Accident Overview
The aircraft experienced a loss of power at approximately 400 feet above ground level (AGL) shortly after takeoff. The pilot decided to land along the shoreline and ditched the aircraft about 100 yards offshore. The aircraft sank after about five minutes and was not recovered from the 27-foot deep water.
Occupants and Rescue
All four occupants were able to exit the aircraft through the airstair door and sustained only minor injuries. Two occupants swam to shore, while the other two were rescued by the Coast Guard.
Fuel Service
Before the flight, the pilot requested that all four fuel tanks be topped off. The line attendant who serviced the aircraft mistakenly identified it as a King Air and added 110 gallons of Jet A fuel.
Probable Cause
The official probable cause determined that the accident occurred due to a partial loss of engine power from a mechanical failure or malfunction. Contributing factors included improper fuel grade, improper maintenance or service of the aircraft by airport personnel, and inattentive aircraft service by the pilot in command.
