NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

According to the pilot-rated passenger, who was the registered owner of the airplane, shortly after departure one of the pilots smelled "something kind of funny." The commercial pilot noticed that the oil pressure indicator was not registering any pressure, so he instructed the pilot-rated passenger to monitor the oil temperature gauge. Both pilots began scanning the surrounding terrain in case of a forced landing. The engine then began to "buck" and then lost power. The commercial pilot declared an emergency to air traffic control and informed them that they were making a forced landing. The airplane touched down in rough terrain, which resulted in substantial damage to the wings and fuselage. The Federal Aviation Administration inspector who responded to the accident site reported that engine oil was present on the left side of the cowling, over the left wing, and down the belly of the airplane. He opened the cowling and noted that the oil dipstick was in place and the oil filter remained secured to the engine. The aircraft engine was inspected by a National Transportation Saftey Board investigator, who discoved that oil was dripping from the base of the oil cooler. Closer examination of the oil cooler revealed a bulge in the metal between the fifth and sixth base cap. In the bulged area there was a .4 centimeter crack in the metal, through which oil was leaking out.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

Loss of engine power during cruise flight due to a crack in the oil cooler and subsequent loss of engine oil.
