Probable cause

The pilot's failure to properly configure the airplane for takeoff, which resulted in the exceedance of the airplane's critical angle of attack, an aerodynamic stall, and subsequent impact with terrain.

Findings · 4

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot was taking off and had begun to climb out when, the airplane's critical angle of attack was exceeded, an aerodynamic stall occurred, and the airplane impacted terrain. The airplane sustained substantial damage to the fuselage. A postaccident examination of the airframe by Federal Aviation Administration aviation safety inspectors found the trim was configured in a nose up setting for a landing profile. The pilot reported there were no preimpact mechanical malfunctions or failures with the airframe and engine that would have precluded normal operation.

Factual narrative

The pilot was taking off and had begun to climb out when the airplane's right wing dropped. The pilot responded by pushing the airplane's nose over but the wing struck the runway and the airplane subsequently impacted terrain causing substantial damage to the fuselage. A postaccident examination of the airframe by Federal Aviation Administration aviation safety inspectors found the airplane's elevator trim was configured in a nose up setting for a landing profile. The pilot reported there were no preimpact mechanical malfunctions or failures with the airframe and engine that would have precluded normal operation.
