Aircraft involved
Probable cause & findings
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.
Factual narrative
The pilot reported that, during landing on a 2,175 ft grass runway, the airplane ballooned. He pushed the nose down, but the airplane floated and touched down about midfield. He "briefly touched the brakes," but decided to go around. 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 pilot reported that the wind was light and variable, temperature was 32°C (90°F), and the density altitude was 2,000 ft. The airplane sustained substantial damage to the both wings and fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
