| Confidence Rating: |  Accident investigation report completed and information captured |
The engine lost partial power during the initial takeoff climb. The pilot stated that the pre-flight inspection and before takeoff run-up revealed no discrepancies. As the airplane departed runway 17, the pilot realized that the airplane was 'climbing slower than usual.' The airplane was crossing the departure end of the runway, at 150 feet agl, when 'the engine speed dropped noticeably.' The engine power continued to decay until it was at idle, the airspeed continued to drop, and consequently, the airplane began to descend. The post accident engine examination revealed that the internal muffler baffle was not secured to its attaching point and was blocking the engine exhaust pipe/manifold. A review of maintenance logbooks and evidence collected during the investigation indicates that airworthiness directive 70-16-05, which mandates a visual inspection of the exterior and interior of the muffler, was not complied with.
Probable Cause: The partial loss of engine power due to a blocked muffler exhaust pipe/manifold as a result of a loose internal baffle. Factors were the improper maintenance by other maintenance personnel and the lack of suitable terrain for the forced landing.
