Aircraft involved
Probable cause & findings
The pilot’s failure to maintain a proper glidepath and crosswind correction during landing, which resulted in an aerodynamic stall.
Factual narrative
The pilot reported that, while landing in a crosswind, the approach was "too low" and he added power. The airplane then "rolled and veered" to the left. He added that marks on the terrain indicated that the left wing struck the ground and tracks showed that the airplane touched down on the pavement before the runway threshold. The airplane then exited the runway, the nose landing gear collapsed and the airplane came to rest nosed down. The airplane sustained substantial damage to the engine mount, left wing and fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The automated weather observation system located at the accident airport reported that, about the time of the accident, the wind was from 330° at 8 knots. The pilot landed on runway 30.
