Walker Cay

While in level flight the pilot reported both engines failed and all attempts to restart them were unsuccessful. The pilot then ditched the airplane in the ocean, and it sank and was not recovered. The pilot and three passengers were rescued 2 days later. According to fuel consumption estimates there should have been adequate fuel for the entire flight and a reserve.

The pilot stated that start, taxi and takeoff were normal until after he raised the gear handle and the aircraft was climbing thru approximately 150 to 200 feet agl. At that time, he noticed that the left engine rpm was decaying. There was insufficient runway remaining to abort, so he elected to feather the left engine and continue the takeoff. The left prop stopped rotating before it feathered. With additional drag from the left prop, the aircraft would not climb or maintain level flight. The pilot was able to fly the aircraft over buildings and other obstacles (up to 75 feet tall) near the airport boundary. Just beyond these obstacles, the aircraft struck trees and crashed in a wooded area. There was a small post-impact fire near the accessory section of the right engine. An exam and teardown of the left engine revealed that an impeller shaft bearing, Pratt & Whitney part number 288943, had failed and allowed the impeller to rub against the diffuser. No other preimpact failures were found. The pilot, sole on board, was slightly injured.

On final approach to Walker Cay Airport, the twin engine airplane struck tree tops and crashed. All three occupants escaped with minor injuries and the aircraft was damaged beyond repair.
