Probable cause

The pilot's failure to maintain the proper glidepath and his subsequent abrupt maneuver to avoid trees, which led to the exceedance of the airplane's critical angle of attack and resulted in an aerodynamic stall during landing and a subsequent loss of directional control.

Findings · 4

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, on short final, the airplane was too low, too slow, and right of the runway centerline, and that he overcorrected to clear trees located at the approach end of runway 12. Subsequently, the airplane stalled and touched down on the upsloping approach end of the runway. The right wing struck rising terrain in the safety area on the right side of the runway, and the airplane skidded across the grass safety area and came to rest on the parallel taxiway. The airplane sustained substantial damage to both wings and the engine mounts. The runway had rising terrain at both the approach and departure ends. The airport facility directory noted that runway 12 had 20-ft-tall trees 25 ft from the runway threshold and required a 4:1 glideslope to remain clear of them. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Factual narrative

The pilot reported that on short final, the airplane was too low, too slow, and right of the runway centerline, and that he overcorrected to clear trees located at the approach end of runway 12. Subsequently, the airplane stalled and touched down on the upsloping approach end of the runway.

The airplane sustained substantial damage to both wings and the engine mounts. The runway had rising terrain at both the approach and departure ends. The airport facility directory identifies that runway 12 had 20-foot tall trees that are 25 feet from the runway threshold and requires a 4:1 glide slope to remain clear. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
