Source record
Factual narrative
On July 12, 1993, at 1900 central daylight time, a Grumman G-164A, N9780, was substantially damaged upon impact with terrain during a forced landing near McCrory, Arkansas. The commercial pilot, sole occupant of the airplane, was not injured. Visual meteorological conditions prevailed for the aerial application flight. The pilot stated that a loss of engine power was experienced as the aircraft was breaking ground during the takeoff roll. Due to the short length of the airstrip and the barriers at the end of the strip, the pilot felt that aborting the takeoff was not an available option. The pilot broke ground but was not able to clear a willow tree and a ditch at the departure end of the strip. Examination of the engine by the Federal Aviation Administration inspector confirmed that the loss of power was the result of the failure of the number three cylinder assembly. The wreckage was released to the operator at the accident site. -
