Amateur-built S7 N8932L accident near Gardner, Kansas

Probable cause

The pilot’s exceedance of the airplane’s critical angle of attack during the takeoff, which resulted in an aerodynamic stall and loss of airplane control at too low of an altitude to recover.

NTSB analysis

The pilot was in the front seat and a passenger, who is a flight instructor, was in the rear seat. Due to his injuries, the pilot was unable to recall what happened during the accident sequence. The passenger reported that during the takeoff, the airplane began to drift to the right. The airplane came near another airplane that was on the grass and the pilot “pitched up” to avoid the other airplane. The airplane exceeded its critical angle of attack, which resulted in an aerodynamic stall and loss of airplane control at an altitude too low to allow for recovery. The passenger estimated the aerodynamic stall occurred at 50 ft agl. The airplane impacted terrain, came to rest upright, and a postimpact fire ensued. The airplane sustained substantial damage to the fuselage and both wings.

The passenger reported that the engine was producing full power until the time of impact, and he did not hear any abnormal engine noises during the accident flight. A postaccident examination confirmed flight control continuity for the airframe.
