Probable cause
The decision of the pilot to attempt operations outside the forward center of gravity limit. Contributing to the accident was the pilot's selection of an inadequate runway for the conditions.
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 attempted a takeoff from a 2,300-foot-long dry turf runway with a five-knot crosswind from the right side. A witness stated that the airplane never seemed to gain momentum, its tail did not raise during the take off, and its brakes locked at the last minute before hitting the fence at the end of the runway. The airplane then flipped over on its back causing damage to the right wing, vertical fin, and rudder. The pilot suffered minor injuries and the second pilot was not injured. A postaccident weight and balance calculation showed that the 575-pound combined weight of the two front seat occupants placed the airplane outside the allowable forward center of gravity limit. A postaccident performance planning calculation showed that on a grass/turf runway the takeoff distance would be approximately 2,299 feet with zero flaps, no wind, and with weight and balance within limits.
Factual narrative
The pilot attempted a take off from a 2,300 foot long dry turf runway with a five knot crosswind from the right side. A witness stated the airplane never seemed to gain momentum, did not raise the tail during the take off, and "locked the brakes" at the last minute before hitting the fence at the end of the runway. The airplane then flipped over on its back causing substantial damage to the right wing, vertical fin, and rudder. The pilot suffered minor injuries and the second pilot was not injured. A post accident weight and balance calculation showed that the 575 pounds combined weight of the two front seat occupants placed the airplane outside the allowable forward center of gravity limit. A post accident performance planning calculation showed that with operations on grass/turf runway the takeoff distance would be approximately 2,299 feet with zero flaps, no wind, and with weight and balance within limits.
