Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident

The helicopter impacted water during an autorotation following a loss of engine power. The pilot reported he lost engine power during initial climb and the helicopter landed upright about 75 feet off the shore in about 2-1/2 feet of water. An inspection of the helicopter confirmed flight control continuity. Both fuel tanks contained 25 gallons of fuel and the engine contained 8 quarts of oil. The main and tail rotors showed drivetrain continuity. A large hole was found in the crankcase, near the number one engine cylinder, and the number one connecting rod was protruding from the hole. Examination of the broken connecting rod cap revealed fracture features that were consistent with a fatigue-type failure. Additionally, the material encompassing the fatigue initiation point was galled along with several other areas of the bearing interface.

NTSB Probable Cause Narrative

The loss of engine power due to the fatigue failure of the connecting rod cap. A related factor was the unsuitable terrain the pilot encountered.
