Accident Summary
Shortly after takeoff at night, the airplane impacted a pond located approximately one-quarter mile east of the airport. The accident was not witnessed, and the wreckage was discovered approximately 10 hours later. The airplane was oriented nose-down and partially submerged in six feet of brackish water. A fuel slick was observed on the water's surface.
Investigation Findings
Fueling records indicated that the airplane had been adequately fueled for the takeoff. Examinations of the airframe and both engines revealed no evidence of pre-impact mechanical malfunctions. The flap system was found in the full 40-degree extended position; however, the flap position at the time of takeoff could not be determined from the available evidence.
Pilot Information
The pilot held approximately 900 hours of total flight experience, of which about 100 hours were accrued at night and 475 hours in the accident airplane.
