Accident Details

After departing from Honolulu Airport, the aircraft experienced a double engine failure during the initial climb. It lost altitude and crashed into the sea a few dozen yards offshore. Four passengers were rescued from the water, while five other occupants, including the pilot, were killed. The aircraft subsequently sank and was lost.

Probable Cause

The official investigation determined that the probable cause of the accident was a double engine failure during initial climb due to mismanagement of fuel by the pilot. Several contributing factors were identified:

  • Fuel starvation
  • Failure to maintain flying speed
  • Inadequate preflight preparation
  • Failure to use the pre-departure checklist
  • Improperly loaded aircraft
  • Seats improperly installed
  • Takeoff with rear auxiliary tanks that were not serviced
  • Fuel selector valve configuration different from other aircraft flown
  • All cabin seats separated

These factors collectively led to the loss of engine power and subsequent crash.
