Probable cause

The pilot’s exceedance of the airplane’s critical angle of attack during a turn, which resulted in an aerodynamic stall/spin.

Findings · 3

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that, while maneuvering about 1,300 ft mean sea level (about 600 ft above the ground), he initiated a 180° right turn, and about halfway through the turn, the airplane began to descend rapidly and would not respond to flight controls. The airplane struck a tree, spun to the right, and came to rest on a residential house. Postaccident examination conducted by the pilot revealed that all controls were intact and operational. The airplane sustained substantial damage to the fuselage, empennage, and both wings. In a written statement provided to the local police department, the pilot reported that he lost control of the airplane, and it "spiraled down" and then struck a tree and a house. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. Given the pilot's statement, it is likely that the airplane entered an aerodynamic stall/spin when the pilot exceeded the airplane's critical angle of attack during a turn.
