Probable cause
The pilot's delayed decision to go around in high-temperature and high-density altitude conditions and his exceedance of the airplane’s critical angle of attack, which resulted in an aerodynamic stall.
Findings · 5
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 landing on a 2,175-ft-long grass runway, the airplane ballooned. He pushed the nose down, but the airplane floated and touched down about midfield. He added that he "briefly touched the brakes" but decided to go around. He added that he raised the flaps to the takeoff position and added full power, but "the delay of power in the diesel and high temperature did not allow for enough climb performance." The left wing aerodynamically stalled, and the airplane impacted vegetation. The airplane sustained substantial damage to both wings and the fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot reported that the wind was light and variable, the temperature was 32°C (90°F), and the density altitude was 2,000 ft.
