N77UK – ALEXANDER SCHLEICHER GMBH & CO ASH 31 MI – 2026-04-13 NTSB Accident Report

On April 13, 2026, about 1051 Pacific standard time, an experimental Alexander Schleicher GMBH and Co., Ash 31 Mi Glider, N77UK, was substantially damaged when it was involved in an accident near Williams, California. The pilot sustained minor injuries. The glider was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.

The pilot reported that he departed from Williams Gliderport (CN12), Williams, California, in the self-launching motorglider. During climbout, about 200 ft above ground level, the engine lost power. The pilot verified that the emergency fuel pump was on and then reviewed his landing options. There were power lines straight ahead, so he opted to perform a right turn back to the runway. However, during the turn, the right wingtip struck terrain. Subsequently, the glider’s nose and main gear impacted a plowed field and resulted in substantial damage to the fuselage and wings.

Witnesses located at the airport reported observing the glider depart uneventfully until it passed behind a hangar and was no longer visible. Shortly thereafter, the witnesses observed the glider again in a steep right turn.

The glider was recovered for further examination.
