Probable cause
The passengers interference with the control yoke, which resulted in the airplane entering an unusual attitude, and the pilot overstressing the wings during the recovery.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot was demonstrating a stall, with flaps extended, to the passenger who abruptly pushed the control yoke forward. According to the pilot, the airplane went beyond vertical and descended from 3700 to 1200 ft MSL before he recovered. The pilot landed shortly afterwards. Post examination of the airplane revealed, the flaps, and wings were substantially damaged.
