Probable cause

The airplane’s inability to climb during takeoff due to a degradation of engine performance due to high density altitude. Contributing to the accident was the pilot’s decision to continue the takeoff.

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 reported that, during takeoff with a density altitude of 6,750 ft and the airplane’s weight near gross weight, the airplane’s acceleration seemed sluggish. The airplane lifted off about 1/3 of the way down the runway after achieving 55 knot rotation speed, but the climb was also “sluggish”. The airplane cleared the airport perimeter fence and began to settle. The airplane subsequently touched down on soft dirt and nosed over. The airplane sustained substantial damage to both wings. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation and he believed that the cause of the accident was a combination of high-density altitude and the airplane’s weight close to the maximum allowable gross weight.
