Crash of a Piper PA-61P Aerostar (Ted Smith 601) in Sinton

After takeoff for a maintenance check flight, both engines on the twin-engine airplane experienced a loss of engine power. The 7,200-hour pilot had recently purchased the airplane, which had not been flown for nearly four years. The pilot, who is also a certificated airframe and powerplant mechanic, completed the inspection of the airplane prior to takeoff. During the engine run-up, the pilot noticed that the RPM and manifold pressure on the left engine did not correspond with those of the right engine. During the takeoff roll, the pilot believed the RPM on both engines began to rise to near acceptable levels, but not entirely. However, he did not abort the takeoff. The airplane became airborne for a short time, and then began to descend into trees before impacting the ground. The reason for the reported loss of engine power could not be determined.
