Narrative:Witnesses in the area observed the airplane make a slight right bank turn followed by a left bank turn toward the runway. The left bank increased to about 45 degrees, before the airplane “dropped” to the ground. Data extracted from the on-board GPS unit indicated that the pilot overshot the extended runway centerline while on the base leg then made a tight left turn back toward the centerline. The airplane impacted the ground, coming to rest less than 1 mile from the approach end of the runway. Given the witness statements and the GPS track, it is likely that the pilot overcorrected the airplane’s course by making a steep turn at low speed, which led to a stall. A postaccident examination of the engine, airframe, and related systems revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation.
Probable Cause: The pilot’s failure to maintain aircraft control while maneuvering in the traffic pattern, which resulted in an aerodynamic stall.
