blog: Yak-18 added to the Foundation

With a lot of patience, blood, sweat and tears, Jean Micheal Le Grand finished his Yak-18 project with OO-IAK “MAX “ and we are proud to welcome him within the Yakkes Foundation.

June 12 was D-Day, the Yak-18 was airborne for the first time since a long time. Jean Micheal is a proud man, and he should be, what a beauty!

The Yak-18 prototype was nicknamed “MAX” by the NATO and has flown for the first time back in 1945. It was the concept for several military trainers. The Yak-18, which became the standard trainer for Air Force flying schools and DOSAAF, is in wide use in China, Poland, Russia, and in many other countries.

Revisions of the Soviet Union's basic Yakovlev UT-2M trainer in 1943 included the enclosing of the tandem cockpits and the replacement of a tailskid with a tailwheel. The new variant, designated the UT-2MV, provided the basis for the Yak-18 prototype, first flown in 1945, when the dust of the last WWII battle had hardly settled. With an all-metal structure and mixed fabric/metal covering, the aircraft went into production in 1947, with a comparatively small engine. Built in large numbers as a "tail dragger," the plane was redesigned as the Yak-18U in 1955, with increased wing dihedral, longer fuselage and partially-retractable tricycle landing gear, for use as a jet pilot primary trainer. Despite significantly increased weight, the plane used the same old Shvetsov M-11FR radial engine as the prototype, with predictably disappointing performance. But after it was given a new engine, the 260hp Ivchenko AI-14R radial, in a revised cowling, it served for many years as the primary trainer in the Soviet Union and many client nations, under the designation Yak-18A. There were other variants, sometimes in quantity, such as the Yak-18P, a single-seat aerobatic aircraft that first flew in 1961.

Manufacture of the Yak-18 trainer was suspended in 1967 with 6,670 of all versions built, many for export. However, in that same year, production was begun on a significant redesign, the Yak-18T, which was virtually a new machine, a four-place sport/touring aircraft, with side-by-side seating for the pilot(s) and passengers. Production of the Yak-18T continued into the 1980's, with more than 1,000 built. Like many popular aircraft, the Yak-18T has a certain Phoenix-like quality. Thus, the independently operated Smolensk aircraft factory resumed roduction of the plane in 1993.

Back in 1998 Jean Michel Legrand, Airbus captain at Sabena Airline, became interested with vintage aircraft. A friend of Jean Michel told him that he knew of a wreckage of a Yak-18 at a former airspace base in Baikonour Russia. After getting the parts of what once used to be a Yak-18 into Poland, they started to work on the project. Finding the missing parts was the most difficult part of the project. Fortunately, many CJ5 parts actually fit quite nice. In Poland, Woicheck Gorzyck of DuskaAir in Wroclaw masterminded the restoration. Most of the work was actually done in it’s own home, housing the fuselage in the hallway, wings in the basement and engine parts in the living. it was always very special to visit the project, says Jean Michel.


Gorzyck’s dad, who used to be a mechanic at Yak-18’s during the cold war in the Polish air force, loved the project and volunteered his assistance. His experience was worth gold.


Early 2008, the project was about to be finished and the aircraft was transported to Belgium where it has been assembled. June 7, al paperwork was finished, June 12, the aircraft went airborne again after having been earth-bound for a long long time. Great job Jean Michel!

In the future this Yak-18 will be presented at many events, flown by Jean Michel. Keep visiting our website for the schedule.

column: Dealing in Russian aircraft by Richard Goode

Over the years many people have asked me how and why I got into this curious business which is, I suppose, totally fascinating and absorbing, but also utterly frustrating in probably equal amounts!

It all went back to the 1978 World Aerobatic Championships - the first in which I had competed; I was then flying a Pitts Special. I was totally in awe of the Yak-50s, which had of course, dominated the 1976 World Championships but were facing tougher competition from the Czechs, with the new Zlin 50, as well as rather better Americans. Also the Russians were affected by the recent death of Letsko, the 76 Champion, who had been killed following airframe failure in his Yak-50 (itself caused by over enthusiastic flying), which had happened a couple of weeks before the Championship.

I then made every effort that I could to purchase a Yak-50 – contacting Yakovlev themselves; the Russian Embassy and Trade Delegation in London etc. This led me into a variety of interesting encounters with Russian spies and British Counter-Intelligence. However after a year or so it became clear that the Russians really were simply not geared to selling a light aircraft of this sort to the West.

The breakthrough came in 1986, when a friend of mine, Wolfgang Jaegle, who was in the German Team, and shared my enthusiasm for Yaks, put together a deal with the East German (then DDR) flying authorities who had had 50s for some eight years, but flew them very little, and were interested in buying Zlin 50s. The deal was essentially one to provide the engines; props; oil coolers, and a few other Western-sourced components to Zlin to make the new aircraft, in exchange for six Yak-50s. Wolfgang invited me to join the deal, and after a long and interesting story and formation ferry-flight from East Germany, I ended up with two; Wolfgang kept two and we sold two to the States.

I was then lucky enough to obtain very good sponsorship for the 50s from Vladivar Vodka, an English Vodka company, which tries very hard to be Russian, so the idea of promoting through Russian aircraft was a good one. This relationship worked well for some three years, until Vladivar themselves were taken over. However it brought me to the attention of the Russians as being the one person in the West who seemed to be successfully operating Yaks without any formal support (indeed the Russians continued to deny that these 50s were even in the West).

Sukhoi then brought out the Su-26 in the middle eighties, and by 1989 were keen to sell them to the West. Sukhoi contacted me to see if I was interested in flying the 26 when it came to Farnborough – I am sure you can imagine my reply! In the event it had an unusual engine problem, so, although I sat in it, I was unable to fly, which was somewhat frustrating. However the Russians then invited me to Moscow with a view to fly the plane and (they hoped) buy one. I suppose, somewhat inevitably, this is what happened. Those were heady days; the Russians had lots of money – when I went to Moscow I had a huge “Chaika” limousine at my disposal, and it was clear that Sukhoi really were going places. In order to maximise the publicity, I persuaded Sukhoi to deliver my first 26 in a big Iluyshin-76 transporter, and indeed was able to persuade our Ministry of Defence that it could be allowed to fly into Royal Air Force Abingdon, the first time that a Russian Military aircraft had flown into a RAF base.

I was developing a good relationship with the commercial guys at Sukhois, and it was not long before they asked me if I would help them sell Sukhois in the West. They were in the process of recruiting a US Agent called Brian Becker, so he and I divided the world between us with him having the US – obviously the biggest single market, and me having the rest of the world. In those days Russian production worked well; there was no problem with parts; and, although there was the odd delay, aircraft came out on time and to specification. However it was not without its dramas – on one occasion I went to Moscow, with the particular aim of inspecting a new Sukhoi destined for an Australian customer, only to be told that the entire factory (clearly a top secret establishment) was closed to all foreigners and that I was not going to be allowed in. I created quite a fuss, pointing out I had come to Moscow to see this one plane, and after a lot of high level discussions, I was allowed to the rear of the Sukhoi factory in the middle of the night, which then opened up onto the historic Moscow Central Airfield (which was still being used by Sukhoi for initial light aircraft test flying); the backdoor of the factory was opened; the Sukhoi was pushed out; I inspected it under powerful light they provided; it was then pushed back inside and I was allowed to go back to my hotel.

Before I go further, you should understand that at that stage there was no private aviation at all in Russia. Effectively everything was military; Aeroflot, i.e. everything that was remotely General Aviation, and finally DOSAAF, which was the sport flying side of the military, but controlling parachuting/gliding and of course fixed-wing flying.

So DOSAAF controlled almost all flying as far as 52s were concerned. This meant that all over the Soviet Union there were individual flying clubs to which any citizen could go, and if they had the ability; fly; do aerobatics etc. However it was a very military environment, and very far from a social club!

What had happened was that DOSAAF placed a huge order (about 150 aircraft) in early 1990 for 52s to be delivered that year and in 1991. Of course the Soviet Union then collapsed, and so a lot of these aircraft were delivered – this was always done in hermetically sealed wooden containers with the aircraft disassembled – to airfields all over what was now Russia, but with no money to assemble them, let alone fly them. My friends at Sukhoi got to hear about a number of these aeroplanes, and having the right high-level contacts with DOSAAF arranged to do a deal, whereby DOSAAF would sell; I would buy; they would handle all intermediary transactions. This was quite a successful line of business for us, I think that, overall, we sold over thirty of these “never used” 52s, with the last one being in, I think, 2000. In the beginning all had a huge amount of equipment, including ladders; covers; jacks; tools; spares etc, but by the time that we got to the later aircraft most of this had been stolen!

Our relationship with individual DOSAAF Regional Managers, led us to realise that there was an awful lot of older 52s lying about, and, by and large, not being used. We began to buy these aeroplanes and, after overhaul, sometimes in Russia, sometimes in Lithuania and of course sometimes in the UK, then sold them.

At this stage various other people were coming into the market, and although we tried, insofar as was possible, to ensure that everything that we bought was legal; had been officially cleared for sale, without any doubt a lot of aircraft and associated equipment was quietly removed from airfields at a stage that the local manager had been paid to take a day off work or whatever!!

Engines were another area where we quickly became involved. Each DOSAAF airfield tends to have a number of spare engines – a lot new (unused but old-stock), but mainly overhauled. Again, with no flying occurring in Russia, DOSAAF was keen to keep income going, and so we began to buy, and of course sell, these engines, as we did with other parts.

About this time the entire banking system in Russia collapsed, and this was at a stage that we had a lot of business going, so I was forced to make regular visits to Russia with a briefcase packed with US $ in cash, simply to pay for the aircraft that we had bought.

Inevitably this led into all other areas of activity. I was then introduced to Slava Kondratiev – the Designer of the Yak-55, and subsequently the Sukhoi 26, who was not only a brilliant designer, but also, by Russian standards, a good businessman. He was fed up with working for large organisations like Yakovlev and Sukhoi, so set up his own Design Bureau, and initially designed the SP-91 (the rather ugly metal Sukhoi Su-29 equivalent), but with the advantage of being either single or double cockpit. He then put the Yak-18T back into production – that had stopped in 1984. So we began selling them directly from the Smolensk factory. They were incredibly cheap – I recollect us selling new aircraft for (then) US $60,000! After a while we then asked the Russians to help us make higher performance 18Ts, with lighter weight; PF, 400hp engines; two piece windscreens; far lighter weight etc. I only wish that we could still buy them at those sorts of prices – current batch of new 18Ts for Russian Ministry of Transport are US$640,000 each!

The next area of activity was new production Yak-3 and Yak-9 aircraft. The distinction was a marketing one, with the 3 being single-seater and the 9 a 2-seater. This programme had began with an order for ten aircraft from the US “Planes of Fame” museum, but I could see that there was considerable potential beyond that so we started placing orders for these brand new Second World War Fighters to sell to customers. Again quite a success story, until the Orenburg factory, where they were made, fell out with the local Mafia; guys came in with machine guns one night and literally took everything, from the Yak-3/9 business, including all jigs, fittings and drawings, in eight articulated trucks and drove off!!

Then, of course, came engines. As we were selling aircraft, inevitably we needed more engines, whether to replace time-expired ones; for unfortunate customers who had done wheels-up landings; or for upgrades to 400hp for Sukhoi owners. At that stage Vedeneyev was on its knees – all its government funding having stopped, so they were desperate to have new business. We began giving them all our engine overhaul business, as well as finding unused but old stock engines in Russia; sending them back to Vedeneyev, where they were stripped down; checked; converted to PF specification; dynamometer-tested and then we would sell them.

To fast-forward to today, things are much more difficult! Sukhoi has stopped making new aircraft; new 18Ts are out of anyone’s price range; the Yak-54 production has started and then stopped, and now is about to restart in the Russian Far East; no new engines have been built since 1994, but fortunately engine overhaul is continuing; most of the decent aircraft have already come out of Russia, and one legacy of President Putin is extreme export controls, which means that anything that is aviation related has to be referred to the FSB (the new KGB) for approval, and this can take months, simply to export, for example, a tyre.

So where will it go? I honestly do not know. I can say that business is a lot more difficult – of course we are in more difficult economic times – but many of our traditional areas of business have, for totally different reasons (as above) simply disappeared. However we have sold approaching three hundred aircraft and almost two hundred engines over the years, so we have quite a customer base to continue to service, and, indeed, we are still getting some good aircraft!

blog: Schaffen-Diest & end of season party 2008

Schaffen-Diest was pretty much end-off-airshow season for 2008. We will have some more photo and training flights in the next months, but its end for public events.

There will be an end of year party somewhere in November, keep visiting us for the details.

The 25th Schaffen-Diest Fly-Inn was a good one, over 300 aircraft have visited the small airfield. Eric Coeckelberghs did do some excellent aerial work together with our Yak-52, Yak-52, Texan T6 and Yak-18.
As usual there was super party at Schaffen-Diest, as always one of the best. We would like to thank Guy Valkekens and the rest of the organisation of the Schaffen Diest Fly-Inn for its hospitality. http://flyin.dac.be/

column: Undercarriage slam, by Dennis Savarese

Preventing the undercarriage from slamming down into position with the aircraft on jacks while doing the annual undercarriage extension test (it WILL get your attention), can be eliminated. First let me explain why the undercarriage slams into position when using the normal emergency undercarriage extension procedure. This procedure instructs us to move the undercarriage handle to the NEUTRAL position before opening the emergency air valve. As a refresher, the only reason we use the emergency undercarriage extension procedure is because the main air system is empty (for whatever reason). Under normal operating conditions, with the undercarriage handle in the UP position, the main air tank supplies air pressure to the UP side of the undercarriage actuators while the compressor refills the main air tank. This air pressure acts as a "cushion" when the undercarriage handle is moved to the DOWN position. ie: air pressure on the UP side of the actuator is exhausting out through the undercarriage handle ( the "woosh" you hear when you move the handle or with the handle in the NEUTRAL position). The NEUTRAL position empties the air pressure from actuators. With no air pressure in the main air system, there is no "cushion". In the normal emergency extension procedure, with the undercarriage in NEUTRAL, when the emergency knob is opened, air pressure from the emergency air bottle rushes into the DOWN side of the actuators through a simple shuttle valve on each actuator (which isolates the emergency from the main system on the down side of the actuators) forcing the undercarriage to slam into the DOWN position.

Use the following procedure to eliminate the slamming of the undercarriage during emergency extension tests:

- using appropriate aircraft jacks, raise the airplane off the ground

- assure the rear undercarriage handle is in the NEUTRAL position with the slide lock in place and the front undercarriage handle is in the DOWN position

- in the front cockpit, turn the main air valve on and turn on the BATTERY/MAIN switch and the appropriate toggle switch/breaker for the undercarriage lights

- confirm the DOWN undercarriage lights are on

- next, move the undercarriage handle slide lock to the left

- raise the undercarriage by moving the undercarriage handle to the UP position

- confirm the UP undercarriage lights are on

- turn off the main air valve

- with the undercarriage handle still in the UP position, proceed to the EMERGENCY UNDERCARRIAGE EXTENSION TEST

EMERGENCY UNDERCARRIAGE EXTENSION TEST

- DO NOT MOVE THE UNDERCARRIAGE HANDLE TO THE NEUTRAL POSITION at this time as this will exhaust the remaining air pressure on the up side of the actuators

- slowly open the emergency air valve; you should see the undercarriage UP lights go out and the DOWN lights may also remain off

- with the emergency air valve still open, move the undercarriage handle from the UP to the NEUTRAL position; air pressure will begin to exhaust through the handle

- the undercarriage will now move gently into the DOWN position and the DOWN lamps will light. Explanation: the air pressure that remained on the UP side of the actuators by leaving the undercarriage handle in the UP position now acts as the "cushion" or "shock absorber" when the emergency valve is opened

- close the emergency air valve

- move the undercarriage handle from the NEUTRAL position to the DOWN position

- now you must release the pressure on the actuator shuttle valves.

IF THIS IS NOT DONE, THE UNDERCARRIAGE WILL NOT FUNCTION USING THE NORMAL PROCEDURE.

- On standard Yak 52's with pneumatic brakes, using the brake handle on the stick, squeeze and release the brake handle until there is no longer any air pressure exhausting when you release the brake handle. This is accomplished when the relief valve just below the front seat on the right side offers a sound much like a human passing gas. Once the relief valve has sounded off, you may then open the main air valve. The actuators will now pressurize on the DOWN side.

- On Yak 52TW's and W's since neither has pneumatic brakes, the factory installed a pressure relief valve for the emergency system on the rear corner of the console on the right side. Open this valve and let the air exhaust. Once you no longer hear air leaking out, close the valve.

- Next, OPEN THE MAIN AIR VALVE and perform a NORMAL undercarriage retraction/extension from either the front or rear cockpit. Be sure the undercarriage handle is in NEUTRAL in the cockpit you are NOT operating the undercarriage from.

- It is recommended to cycle the undercarriage from the rear cockpit as well during the annual testing of the undercarriage.

Good luck,

blog: A dirty job...

After a very slow start of Yakkes season finally everything is back on track. The red Yak suffered some problems and in combination with bad weather makes that our baby was more in the hangar than outside. The bus also suffered a lot of problems with its chassis. We’ve renovated the bottom of the bus completely and it will be ready for the airshows.

Last weekend, it was Sanicole Airshow time. The most favorite airshow of all. So much fun and so much to do. Besides the airshow demo both the Yak and the T6 were used for photo ship to take some beautiful shots. Eric Coeckelberghs, our photographer, had the time of his life. A dirty job, but somebody has got to do it.

See you all in Schaffen-Diest, August 16.

blog: Texel Fly-Inn 2008

The 2008 Texel Fly-inn was, .as always, well planned and a joy to visit for the red Yak. Perfect weather, with a gusty wind later in the afternoon, attracted all sorts of flying machines. For Yakkes Erik Kraaijenhof and Eric Coeckelberghs (los dos Enricos), took off from Eindhoven to grab some pictures, preferably from the air, of the DC6, Catalina and the DC3 at Texel.
Unfortunately the DC6, after a lot of confusion, never showed up!
But a unique combination of the Dakota and Catalina created some great shots from the air. We even have the Catalina on film during a “splashdown” waterlanding. Images will be published soon.

Thanks to a well oiled organisation led by Mister Ed (de Bruin) and son the Texel Fly-inn was a great succes!
Stay tuned !

blog: Fitting a smoke system in a Yak 52

by Theo Hendriks G.W.K.,A & P,I.A.
It started with a smoke system that is designed for Yak52 and can be purchased via Spruce.

The Baggage compartment seems to be the best place, but when I did a bit research with our Russian mechanic, he adviced me to install behind the baggage compartment there used to be 20 Kg of radio equipment that was removed, so no center of gravity problems when installed.
The main problem was how to fill the tank? The only option was to install a filler-cap, so we ordered a filler cap as well. First I tried if it would fit in this space, there was a unused bracket that was in blocking the tank, so it had to be remove first.

To build a bracket that was strong enough, a profile or extrusion and a bend sheet of 2024 T3 alclad is been used. The L shape profiles is standard kit equipment.


Another problem showed up. You are not able to reach the aft screws to secure the reservoir to the bracket.
The plastic “wings” are removed from the screws and installed them with a nut to secure them. Now you are able to slide the reservoir into the bracket and can be secured.



Also a rising bracket was riveted to the lower L shape plate to secure the tank on the top side


An adapter was designed to fit on the tank filler cap so a 2 inch hose could fit. The new filler cap was installed behind the canopy so that the area was as flat as possible and would not cross any beams or ribs on the inside. 3 rivets where removed and 2 countersink rivets where installed in stet, one hole was use to install the filler cap with a screw and nut.


Finally a connection was made between the tank and filler cap with cast iron elbow’s and 2 inch Mil-H 6000 hose. Then I realized that when this tank is overfilled with paraffin or diesel it will leak via the vent line on till the level was equal. To prevent this I installed the vent line over the filler connection.
The Yak has an 24 Volt system and the smoke system is designed for 12 Volt so a converter is added to the kit. Behind the instructor seat is enough open space to install and cool it.
In the wiring diagram delivered with the kit they added the converter before the arming switch, that means that the converter is always active, it has been changed in a way that the arming switch arms the hole system including the converter. The Landing-lights where removed earlier so I used that switch to arm the system. To Activate the system I installed a switch right of the starter-switch (Red) and a LED that comes on when the system is armed. With your hand on the throttle you can reach the switch. A remote switch is installed on the control stick to activate they system shortly.


And Yes !! it does work !!

blog: Howely smoke !!!

Look what they are doing to our bus !!!This is a mighty GAP, this is where the bar will be, so it will accessible from the outside also. Handy Hendriks installed a smoke system to the red Yak. I took him a bit time more than planned but it's installed now. Theo installed it in a way that we still can use our cargo hole, some smart work. So it's testing time! Light her up Theo.
No doubts it works fine !
Poor tailchasers in the future :-)
Nice, isn't ?
Good Job Theo !

blog: Let's blow it up....

Maintenance time. All panels are removed which gives the opportunity to take some rare images.


Gear check, see the footage.

Let's blow up the air bottles !
Here a look from the inside, the upper bottle is the emergency bottle, the lower one is the main 50 psi airbottle. All Yak's do have an airsystem for the flaps, gear, breaks and startengine. No hydraulics or what so ever for these systems.

The fusulage from the inside, see the steering cables.When the back seat is removed, other angles of the cockpit can bee seen.Scary moments

Low-cost High flyers

Couple of weeks ago a friend of the Yakkes Foundation, ATCbox.com requested us to co-operate with Stichting Hoogvliegers (High Flyers Foundation). The foundation targets to give very, very ill children the day of there live by arranging a never to forget flight for them. Of course the Yakkes Foundation is willing to co-operate, however as you know the Yak is not the most comfortable aircraft to do some scenic flights. So we thought in this particular very special case we could make an exception by calling one of our sponsors and ask them for a BIG favor. The sponsor in this case is Solid aiR, and YES, they are willing to co-operate and give them a ride with the Dornier 328 VIP. We can write a huge and large story, however, one images will tell a multiply of thousands words, so what about a couple of images? If your hart is at the right place, place support these guys, they need it more than who else! Stichting Hoogvliegers








Again, sponsor those guys: Stichting Hoogvliegers
they need you ! It's worth it, every penny !

Is it a Yak?

Nope, it’s the T-6 form Hanno Wesdorp and Zlin from Victor Telkamp. Excellent formula for a fun afternoon at Hilversum. Here some shot we took.



And GUESS who talked herself into the T-6 ???
At the way back to Sanicole, our newest Yakkes member had the ride of his life !
which resulted in a great new ground crew :-)
Stay tuned, great news is coming up soon !
Btw, are you a Yakkes member already for the 2008 season? http://www.yakkes.com/join.php

Schaffen-Diest; old-timer fly-inn

Together with approx 290 other aircraft, Yakkes joined the 2007 Oldtimer Fly Inn at Schaffen-Diest. Arriving at a lousy weather Friday with a very low overcast, poor visibility and a lot of cold beer, it turned out to be a great happening with beautiful weather at Saturday and Sunday.

A lot of old friends were present and a lot new ones. Finally had the chance to meet Hans Hollink again with his brand new 400hp Yak-52, RA-3411K, boy what a beast. It shines like a… well it shines very well, excellent paint job.

Peter was enjoying himself with Sasha, the Yak-50, busting the airfield from several directions, getting all spotters run like hell :-)


Saturday afternoon it was time for price-winner Mr. Marco Beurskens to collect his prize:a free Yak-ride! After the safety-briefing Marco was strapped in the tiny seat.Demonstrating the capabilities of this wonderfull machine and enjoying the beautiful flying weather Erik Kraayenhof
took Marco up in the skies for a fifteen minute ride. After touchdown the very pleased price-winner declared:



"Never thought I could win this prize by simply becoming a member of the Yakkes Foundation!" What about you? WIN A FREE RIDE

Rehearsal fun

Before each airshow you do have to rehearsal. This is to get familiar with the scenic and to show that you are safe. Sometime it gives you the chance to have some great shots.
