Aviation Accident Summary FTW00LA248

GUTHRIE, OK, USA

Aircraft #1

N8783S

Cessna 150F

Analysis

During takeoff, the airplane was climbing through 100-150 feet agl when the engine lost approximately 200-300 RPM. The pilot stated that soon after the engine lost power, the stall warning horn sounded at approximately 45-50 mph, while he was 'trying to maintain altitude.' The pilot flew the airplane toward a field, and the engine regained power and immediately lost power again. The pilot extended 30 degrees of flaps to slow his approach to the field. The pilot reported that the field was rough and had '12 to 18-inch ruts.' The airplane touched down in the field with the left main landing gear first, and bounced after impacting a deep rut. The airplane then impacted the ground with the left wing tip. Subsequently, the nose landing gear collapsed, and the airplane nosed over and came to rest inverted. The FAA inspector stated that he could not find any anomalies with the engine that would have prevented its operation.
