From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Pilot states his engine quit at the 180 degree position downwind of runway 27 at Twin Lakes (8A7). Pilot elected to use carb heat just before this event instead of further out. Pilot suspects engine quit due to carb ice. Aircraft speed was 65 mph, altitude 1,000 feet AGL (1,600 MSL). Once engine quit pilot elected to initiate a very tight, hard left to final to ensure he cleared the tall trees at the end of runway. Pilot knew he was too fast and too high for a normal landing so he chose to hold a full side slip to bleed off as much speed as possible. He got the aircraft slowed and on the ground just prior to the end of the runway, which was too close. Rather than run off runway which is a very steep drop to the tree line, pilot elected to turn into brush and vines to bring aircraft to a full stop. At this point the airplane came to a stop and gently flipped over on its back causing right wing spar to crack.
