Hi
There was a fatal yak52 crash in Poland this last week-end, very tragic for all involved.

I’m just curious on what could have gone wrong and why the pilot didn’t manage to get out of it, looks to me like a normal spin, not flat, but also looks like ailerons are not where they should be to get out of this spin.?

Here is one of the links to the video

I saw another video and the ailerons are not neutral during the spin but around 60 meters (200 feet) the ailerons appear to be neutral, the elevator is still full up indicating the aircraft is still stalled but he stops the spin to the right, gets the aircraft neutral and begins a  slight left turn before impacting the water. It appears he began the recovery too low in order to complete the maneuver. More altitude and he would have successfully recovered.

Foreign objects blocking the elevator at the rear of the fuselage after aerobatics. ?? A typical cause for a fatal crash in the 52 .

The pilot was experienced on the 52, and typically used a spin manoeuvre in
his display sequences. However, looking at the video, it does seem that the
elevator was up – i.e. he was not attempting to recover. Whether this was
due to control restriction or some form of pilot incapacitation I don't
know. But from my previous experience, control jamming tends to be apparent
on detailed inspection, even although it was a violent accident and the
aircraft very badly damaged.

The FOD barrier is mandatory on G-reg Yaks, following the G-YAKW accident. I was talking to two of the former co-owners of that aircraft today in fact. Whether a control restriction was a factor in this case, I have no idea but I’m surprised the FOD barrier is not mandatory everywhere.

I watched the video also and agree with Greg. He started recovering to low. The spin looked flat to me. Jim "Pappy" Goolsby
