Probable cause

The pilot's failure to maintain a proper landing flare, which resulted in an aerodynamic stall, bounced landing, and subsequent secondary stall during a go-around attempt.

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, during the approach to land, as he reduced power the descent rate increased and he flared to reduce the descent rate. He added that the flare was high, and the airplane aerodynamically stalled about 6 ft. above the runway and bounced. When the airplane bounced, the airplane veered to the left and he applied power to go-around. During the go-around, as the airplane approached obstacles off the runway, he "pulled up too much," and the airplane aerodynamically stalled and impacted the ground. The airplane sustained substantial damage to the fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
