Amateur-built CH601-HDS N4263 accident near Frankston, Texas

Probable cause

The pilot's failure to maintain adequate airspeed while maneuvering at low altitude, which resulted in the airplane exceeding its critical angle-of-attack and experiencing an aerodynamic stall. Contributing to the accident was the pilot's decision to make a steep turn at low altitude.

NTSB analysis

The pilot and passenger were returning home after attending a fly-in at another airport. The passenger reported that, during the descent to land, the pilot spotted a boat on the lake that they were overflying and began to follow it at low altitude. The pilot then made a steep turn, which resulted in the airplane exceeding its critical angle-of-attack and experiencing an aerodynamic stall. The pilot then lost airplane control, and the airplane subsequently impacted the water. The pilot and passenger were rescued by nearby boaters. The airplane wreckage was not recovered from the water; neither the pilot nor passenger reported any anomalies with the airplane before the accident.
