Aircraft Accident/Incident Report

Gustavus, Alaska 99826
Saturday, July 1, 2006 10:40 AKD

NTSB Narrative Summary Released at Completion of Accident

The private certificated pilot was in cruise flight about 2,000 feet above the ground (agl) on a Title 14, CFR Part 91, cross-country personal flight. He began to smell, and then see, what appeared to be smoke emanating from the engine, which subsequently lost power. He lowered the flaps and landing gear and performed an emergency landing on a beach. During the landing roll, the nose gear collapsed. The pilot reported that while waiting for rescue, he discovered that the number four cylinder connecting rod had fractured, and was protruding through the top of the engine case. Postaccident examination of the engine revealed that the number 4 connecting rod was fractured at the base of the rod beam. Fragments of the rod cap, the rod bearing, and the connecting rod bolts had thermal and mechanical damage. The rod cap bolts were necked down at the point of fracture. Fragments of the rod bearing were located in the engine oil sump. The engine had accrued 1,482 hours since its last overhaul in 1970, and 9 hours since its last annual inspection on June, 24, 2006. The engine manufacturer's recommended Time Between Engine Overhaul (TBO) for the accident engine is 1,500 hours, or every 12 years.

NTSB Probable Cause Narrative

The fracture of an engine connecting rod during cruise flight, which resulted in a forced landing on a beach, a collapsed nose landing gear, and substantial damage to the fuselage.
