Event Location
Probable Cause
The pilot’s failure to maintain adequate airspeed and his exceedance of the airplane’s critical angle of attack during the approach to land, which resulted in an aerodynamic stall.
Full Narrative
The pilot of the airplane reported that, during the approach to land, he applied full flaps, but "unfortunately, [he] added power too late and too slowly". Subsequently, "the bottom fell out" and the airplane aerodynamically stalled. The airplane landed hard, the left and right wing impacted the ground, and the airplane skidded to a stop.
The airplane sustained substantial damage to the fuselage and right wing.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
