What happened
During a scheduled test flight departing from Christiansted, a seaplane experienced significant mechanical issues with its engines. The flight was being conducted on behalf of the FAA at the time of the incident. Upon encountering these engine problems while maneuvering off the coast of Christiansted, the pilot elected to perform an emergency ditching a few miles away from the shore.
All three occupants were successfully rescued following the water landing. While there were no fatalities, the aircraft sustained damage that rendered it a total loss.
Findings
Investigations into the accident identified several contributing elements related to the mechanical failure and the pilot's actions. The primary cause of the ditching was a double engine failure occurring after the flight was attempted despite known equipment deficiencies.
Specific technical observations included:
- A recorded fluctuation of 25 rpm on the left engine during the three days of flight preceding the accident.
- An observed drop to 200 rpm during the climbout phase.
- Inappropriate decision-making regarding in-flight procedures.
- Attempting to operate the aircraft at a level exceeding the pilot's experience or capability.
