Summary
A pilot reported that during an approach, blue smoke and oil were observed trailing from the left engine and wing. Shortly thereafter, flames were seen emanating from the left engine nacelle. The aircraft's cabin filled with smoke, prompting the pilot to execute an emergency landing. During the landing rollout, the left wing detached from the airframe. After the aircraft came to a stop, it was fully consumed by fire.
Events
According to the pilot's report, the first indication of a problem was blue smoke and oil trailing from the left engine and wing during the approach phase. Shortly after noticing these signs, flames became visible coming from the left engine nacelle. The cabin then filled with smoke, leading to the decision to make an emergency landing. The landing was accomplished, but during the rollout, the left wing broke off. After the aircraft came to a stop, it was entirely consumed by the ensuing fire.
Investigation
An FAA inspector examined the wreckage and reported that the extent of fire damage precluded determination of the exact source of the fire. The inspector noted that oil-soaked paint chips were found along the airplane's flight path, approximately 900 feet before the touchdown point. No further information regarding the origin of the fire or the sequence of events was available due to the damage.
