Louisburg, NC, USA

Aircraft #1

N93002

Cessna 152

Analysis

The CFI and student were completing a cross-country flight, and were six miles from the destination airport flying at 2500 feet, when the engine started to run rough for 20 to 30 seconds then quit. The CFI went through the emergency checklist but was unable to restart the engine. The CFI selected a nearby field for an emergency landing. During the landing roll, the nose wheel collided with a ditch and collapsed. Examination of the airplane revealed the nose gear collapsed, the propeller bent, and the firewall damaged. The engine teardown revealed wear and fretting on the main journals, and bearing movement that resulted in engine oil starvation to the crankshaft.. The center journal was loose and appears to have spun, cutting off the oil passage. The last engine overhaul was on January 22, 2001, and approximately 1,102.7 hours had been flown since that overhaul.
