Primary finding
Probable cause
The pilot’s failure to maintain adequate airspeed and his exceedance of the airplane’s critical angle of attack during takeoff, which resulted in an aerodynamic stall.
Investigator assessment
Analysis narrative
The pilot of the tailwheel-equipped airplane reported that, during takeoff, the "wind got more gusty than [he] could handle being too low and slow." The airplane aerodynamically stalled and impacted the ground. The airplane sustained substantial damage to the right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. A review of recorded data from the automated weather observation station located about 5 nautical miles west of the accident airport revealed that, about 42 minutes before the accident, the wind was from 200° at 18 knots, gusting to 28 knots. The takeoff direction is unknown.
