Aircraft Accident/Incident Report

Santa Fe, New Mexico 87505
Friday, December 25, 2009 9:30 MST

NTSB Narrative Summary Released at Completion of Accident

During a departure on a cross-country flight the private pilot noticed an oily smoke entering the airplane's cockpit. As the smoke began to accumulate, the pilot's vision was obscured. The pilot landed on the only runway he could see through the smoke. The airplane touched down with the left wing low and the airplane departed the side of the runway. An overpressure condition in the engine's crankcase resulted in oil being driven out of the crankcase and onto the exhaust system. Smoke entered the cockpit through the heater duct system and gaps in the firewall.

NTSB Probable Cause Narrative

An engine overpressure condition that resulted in oil getting on the exhaust and producing smoke which entered the cockpit. Contributing to the accident was the pilot's obscured vision due to smoke.
