Probable cause

The pilot's selection of a departure runway of inadequate length for the density altitude, resulting in the airplane not gaining sufficient lift, departing the runway, and impacting terrain.

Findings · 3

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 of the twin-engine airplane reported that prior to takeoff, he "didn't lean out the motors". He reported that during the takeoff roll, "there wasn't enough lift and probably the density altitude was involved." The airplane ran off the departure end of the runway into a field, impacted terrain, and sustained substantial damage to the empennage. The pilot reported that the accident was because of "pilot error." The pilot reported there were no pre-impact mechanical failures or malfunctions with the airframe or engines that would have precluded normal operation. The computed density altitude for the departure airport was 8,570 feet at the time of the accident.

Factual narrative

The pilot of the twin-engine airplane reported that prior to takeoff, he "didn't lean out the motors". He reported that during the takeoff roll, "there wasn't enough lift and probably the density altitude was involved."

The pilot reported that the accident was because of "pilot error." The pilot reported there were no pre-impact mechanical failures or malfunctions with the airframe or engines that would have precluded normal operation. ADDITIONAL INFORMATION The computed density altitude for the departure airport was 8,570 feet at the time of the accident. The Federal Aviation Administration aviation safety inspector reported that the pilot was not rated for multi-engine airplanes and that the airplane was not airworthy prior to the accident.
