Sikorsky S-43 | Bureau of Aircraft Accidents Archives

On approach to Kingston, at an altitude of 1,600 feet, the crew modified the position of the fuel selector when the left engine stopped. Due to an insufficient speed, the aircraft stalled and crashed into the sea some 16 km off Kingston. All 18 occupants were quickly rescued while the aircraft sank and was lost.
Crew:
Joseph H. Hart, pilot,
H. E. Allen, copilot,
C. L. Mason, radio navigator,
A. C. Lusignani, purser.

Probable cause:

It is the opinion of the Investigating Board that the probable cause of this accident was failure of the left engine as a result of a failure in the fuel system and failure of the airplane to maintain single engine flight.

Circumstances:

After departure from Hong Kong, while overflying the Bias Bay (Daya Bay), the crew encountered poor weather conditions and decided to ditch the aircraft offshore. Upon landing, the float plane named 'Chekiang' hit waves and lost its both wings before coming to rest. Seven passengers found refuge on a wing and were later rescued by the crew of the British destroyed 'HMS Thracian'. Unfortunately, three crew members, among them the copilot George Ohrnberger, were killed. The captain survived and the aircraft was lost.

Captain / Total hours on type:

991.00

Circumstances:

While descending to Cristóbal-France Field (Colón) at an altitude of some 2,000 feet, the pilot informed ATC that he was approaching the city via the Bahía Limón Bay. In limited visibility due to rain falls, the float plane named 'Santa Maria' went out of control and crashed into the sea few km offshore. Debris were found the following floating on water and all 14 occupants were killed.

Probable cause:

The Board is conclusively of the opinion that the accident was caused by the NC15065 striking the water while moving less then 90 miles per hour, tearing the ship to pieces, causing the death of all aboard and that a fire resulted from the impact with the water. The Board is convinced that at the time of the collision the plane had a minimum of 80 gallons of gas which would have burned on the water a sufficient length of time to cause all burns or scorches found one any recovered wreckage. The specific contributing cause of this aircraft colliding with the water is beyond the knowledge of man. However, there must have been a specific contributing cause or causes, and the Board is of the opinion that the most probable contributing cause is one of the following and in the order named:
- Failure of one or both engines due to faulty gasoline system, occurring during the spiraling down mentioned in the pilot's last radio message.
- The encountering of a sudden severe rain, as altitude was being lost by the plane in the spiraling descent, resulting in the blanking out of all visual contact.
