Etienne I know that it is your habit to publicise everything that you do
in aviation to the widest possible audience. But it is completely
unacceptable to say after an accident report "engine had recently been
overhauled by Aerometal (Hungary)", as if to suggest that the engine failure
was something to do with this overhaul one year before. As I wrote to you in
July this year, it was very clear that the engine and the fuel fittings had
had a number of completely unauthorised modifications after delivery to you
and operating the aircraft. These modifications were all in the fuel system,
and it is a reasonable conclusion that the engine failure was caused by a
fuel problem, and indeed that this fuel problem was almost certainly caused
by the changes to the engine subsequent to its installation. There was
absolutely nothing to suggest a basic problem with the original overhaul,
and I hope you will publish a retraction to accept this.

Dude,
The pictures of your Yak 50 are very cool.
The pictures of the guy getting removed from the Yak-52 are so far from being cool it is not funny. I doubt anyone here ever wants to see a fellow aviator in that condition.
Post as many pictures of flying planes as you like, but please don't post any more of crashed ones, especially ones with injured (or worse) people in them.
Regards
Chris

I almost had an engine related problem myself recently. While getting ready to start my new Siai-Marchetti 1019, I decided to turn the individual fuel tank pumps off because I wanted to reduce current draw to that $2500 battery. Startup and departure were normal. While flying at 2000 feet over heavily wooded terrain, out of the corner of my eye I spotted a yellow caution light. LOW MAIN FUEL was written right below the warning light, one that I had never seen come on before. A quick glance at the left inboard tank (which directly feeds the turbine) showed it nearly empty. My INTERNAL light bulb lit up and I quickly turned all the tank pumps back on again, while getting ready to switch the fuel selector to emergency feed. Thankfully luck prevailed and the left inboard was quickly refilled by the other tanks pumps. This close call was 100% my fault. That said, I am not an airplane pilot, and I do not fly right seat on commercial carriers thus it is OK for me to admit I made a mistake. Of course my story has no immediate value to readers of the YAK List, but neither does the posting below.

I think stories all have value. Lessons learned. Goes to show you that new engine or not, professional or not, it’s those that have and those that will have it happen. The one time you don’t plan on it, Boom! As far as blaming the new engine, that also happens. I had a new Bonanza with less than 50 hours. Engine thru bolts separated as did the block. (at 5000’ directly above an airport) Continental didn’t take it personally. It happens. And I didn’t take offense to it when they asked me if I ran the hell out of it like many do with the yak/cj. Of course I didn’t mention it to the world on line. We didn’t have an “On-Line” back then. Just because it ran good in the morning doesn’t mean it won’t blow up in the afternoon.
Keep the stories coming. Whether u admit it or not, most of us will know what happened. So help the next guy to not make the same mistake. Could be the motor, could be the pilot.
I’d be willing to bet that we would still trust our same engine shop to build us an engine again.
