Location:Akron, OH -   United States of America

Investigating agency: NTSB
Prior to take off, the pilot conducted a pre-flight inspection and engine run-up, and found "nothing unusual." On the take off roll, he rotated at 80 mph. As the airplane began to climb, the pilot said the left engine rpm dropped to 1,500 RPM, and the airplane veered left. He was unable to maintain altitude or directional control, and contacted the ground with the left wing first, followed by the nose. A witness stated that when the airplane was 15-20 feet above the ground, he heard a loud popping noise. The engines revved up and it looked like the airplane was going to land, but continued to climb with louder than normal engine revs. The engines were examined under the supervision of a Federal Aviation Administration (FAA) inspector, and no mechanical deficiencies were noted. The airplane was released to the owner, who later sold it to an airplane salvage company. According to a representative of the salvage company, during a teardown of the left engine, the main bearing was found partially seated on the journal. It appeared blue in color. At the time of the accident, the engine had accrued a total of 1,607 hours since field overhaul.

Probable Cause: the pilot's failure to maintain minimum control single engine airspeed (Vmc) during a loss of power on one engine, which resulted in a loss of control in flight an in-flight collision with terrain. A factor was a shifted main journal, which resulted in a partial loss of engine power.
