More facts are coming out in reference to the ASH26 motorglider crash that killed Dave Kinsell this past August. Looks like the guy spun in from about 260 feet and hit the terrain at a near 80 degree angle, the engine was extended and the last speed was near or less than 50 knots at the turn to final attempt. The final resting place of impact was nearly 90 degrees from the base to final turn, and the oxygen bottle was found 300 feet from impact. Why weren't his shoulder straps buckled, you certainly don't prepare to jump from 260 feet. The glider never reached an altitude higher than his initial climb, although his flight trace showed him trying to thermal on three or four occasions from initial climb to the final impact
on one previous flight dated 10-22-22 near the same location he decided not to start his engine until he was 263m AGL or 862 feet AGL. Looks like this was a classic stall spin, very unfortunate. OBTP

The preliminary report said the mast was partially extended. In the crash pictures, it appeared to be in the "cooling" position, about 30 degrees up from the fuselage. That's normal operation to cool the muffler for about 4-6 minutes after a self-launch.

860' AGL is sufficient for a safe attempt at restarting IF you are on downwind for a good field, and the glider is configured for landing. One attempt to start is about all the time you have, any fiddling around with a problem becomes very risky.

The 10-22-22 restart was over hilly, rocky ground, not nearly as benign as the farmland he crashed in this year, but importantly, there was a very good looking dirt strip nearby with a hangar or house next to it. That time he did it right.

Yes, that time the engine started. OBTP

Eric, if I was a betting man I would bet that the engine was never started and the partial extension was from the tremendous impact. OBTP

It's possible, but it might be the extension attempt failed, or the retraction failed. If we had the flight trace with engine noise level, we could make better guesses.

A bit of new information regarding the accident, looks like it has been determined that the engine was out and probably did not start. Pilot was probably distracted got super slow and spun in on the turn to his anticipated landing spot. OBTP
