Cockburn Harbour - Port-au-Prince
Captain / Total hours on type:
While approaching Port-au-Prince on a flight from Cockburn Harbour, South Caicos, the crew reported an engine failure. Few minutes later, all communications systems failed. The airplane descended and eventually crashed into the sea few km off shore. Rescuers were dispatched on scene and one pilot was found alive while three other occupants were killed.
It was determined that the crew was forced to shut down one engine due to oil exhaustion. Later, two other engines should be shut down as well for the same reasons. The following contributing factors were reported:
- The pilot-in-command attempted operation with known deficiencies in equipment,
- Inadequate preflight preparation,
- Oil exhaustion, engine lubrication system,
- Improper in-flight decisions,
- Communications and navigation equipment: transmitters and/or receivers failure,
- Forced landing off airport on water,
- High oil consumption,
- No oil,
- One engine shut down en route, diverted when two more engines shut down.
