To Chris Cox If you have any sense of self preservation,DO NOT just bolt on a new prop and fly the Yak !! An estimate of $6600 is indicative of a serious ground-strike,and the engine could well be damaged. At its very least,you should remove the gearbox,and send it to be stripped and crack -tested,and at the same time check the run-out on the end of the crank-it should not be more than 0.03mm. We had a UK Sukhoi,where the owner just replaced the prop after a strike,and went on flying.About 3 hours later,when he was taxiing in from an aerobatic sequence,the engine locked solid-a satelite gear in the gearbox had broken up and jammed the whole gearbox. Even at idle,it broke the engine mount,a couple of instruments etc.Had it been 5 minutes before the engine would certainly have come out in flight.

Chris, Richard is absolutely correct. The fact that you need an engine mount leg tells me that engine took a hit in a worst kind of way. I personally would not trust it on a ferry flight. Not sure where the mount is broken but considering it is welded where the arms support and are mounted to the ring. It is bolted to the fire wall in 4 places. It took some force to break a mount that is for sure. You have no idea what kind of force in the form of a rotational moment that was applied to the gears until you tear down the nose case and check. Think about it. It is your rosey pink that is going to be sitting behind it on this ferry flight.

Chris-when you say "the crank" I assume you do not mean the propshaft flange,as you might do with a Lycoming-that is irelevant with a geared engine. Also,you have no way of knowing what damage there might be in the gearbox,and if the original accident broke an engine mount,it was so severe that internal damage is a reasonable possibility. The manufacturer's strict instructions are that ANY ground strike must then have,at a minimum,a gearbox check. In the end,it is not only your neck that could be affected,it is also our insurance premiums and the reputation of these Russian aircraft!!
