The commercial pilot stated that, during the takeoff roll, the airplane swerved to the right, and he corrected to the left and aborted the takeoff; however, the airplane departed the left side of the runway and collided with an embankment. At the time of the accident, a quartering tailwind was present. The pilot had no previous experience in the accident airplane make and model or in any other multiengine airplane equipped with engines capable of producing 300 horsepower. During a postaccident conversation with a mechanic, the pilot stated that the airplane "got away from him" during the attempted takeoff. Because a postaccident examination of the airplane did not reveal any evidence of a preimpact mechanical malfunction or failure of the airplane's flight controls or nosewheel steering system that would have precluded normal operation and the pilot did not have any previous experience operating this make and model of airplane, it is likely that the pilot lost directional control during takeoff with a quartering tailwind.

After takeoff while over the departure end of the runway, deep gray colored smoke was observed by the tower controller trailing the right engine. The pilot was alerted of this and advised the controller the flight was returning. Witnesses reported seeing smoke trailing the right engine and that the airplane rolled to the left, pitched nose down, impacted trees, and then the ground. A fatigue crack was detected in the exhaust aft of the No. 6 cylinder of the right engine; and incomplete fusion of a weld repair was also noted. Heat damaged components from the right engine were replaced and the engine was started and found to operate normally. A foreign object of undetermined origin was found in the intake area of the No. 3 cylinder. Analysis of the voice tape revealed both engines/propellers were operating near full rated rpm when the pilot acknowledged the transmission that smoke was trailing the right engine, one engine/propeller rpm then decreased to about 2,160 rpm. Examination of the flight controls revealed no evidence of preimpact failure or malfunction. Flap positions at impact could not be determined. Calculations indicate that the airplane was approximately 55 pounds over the maximum certificated takeoff weight at takeoff.

The airplane departed at night after maintenance was performed on the left engine. The pilot attempted to return to the airport and while on base leg struck the ground inverted and nose down. The left engine propeller was found feathered. On the left engine, the # 5 cylinder was off the engine and the # 5 piston with the connecting rod still attached were found nearby. Interviews revealed that during maintenance, the # 1,3,5,and 6 cylinders had been removed and reinstalled; however, the # 5 cylinder had not been tightened. Several people had worked on the airplane at various stages of the work. The maintenance facility did not have a system to pass down what had been accomplished, and the FAA did not require the tracking of work accomplished in other than 14 CFR Part 121, or 14 CFR Part 145 facilities.
