Incident Sequence
The pilot reported that during takeoff, the engine began to miss at approximately 300 feet above ground level, and a definite loss of power was felt. The pilot attempted to raise the landing gear, but the airspeed was below the automatic gear extension speed, preventing gear retraction. The pilot then repositioned the gear handle to the down position, which stopped the warning horn that had sounded. The pilot was able to fly the aircraft over some wires but could not maintain airspeed. Subsequently, the landing gear collapsed during a landing in a soft farm field.
Investigation Findings
An investigation revealed a fuel leak at a union joint in the fuel line from the left wing. No other preimpact malfunction or failure was evident. The gross weight was estimated to have been approximately 87 pounds over the maximum limit. Additionally, the density altitude was approximately 3,500 feet, with a temperature of about 110 degrees Fahrenheit.
