Narrative:
The pilot and three passengers departed on a personal cross-country flight when the pilot heard and felt a sudden reduction in engine power during initial climb. He told the tower controller that he had engine trouble and requested an immediate landing. The pilot was unable to maintain altitude and, as a result, deployed the airplane's emergency parachute system. After a successful parachute deployment, the airplane contacted power lines shortly before it impacted the ground in a nose-level attitude. After the airplane landed, the occupants egressed, and a fire erupted that destroyed the airframe.
A postaccident engine examination revealed that the induction tube coupler closest to the No. 1 cylinder was partially disconnected from its associated inductiontube. Although both coupler clamps were tight, the clamp closest to the No. 1 cylinder did not overlap its associated induction tube. Additionally, the cylinder No. 3 induction tube was fractured at the cylinder mounting flange. A laboratory examination of the cylinder No. 3 induction tube revealed multiple areas of fatigue; however, the cause of the fatigue could not be conclusively determined due to postfracture damage. The material properties of the induction tube were consistent with the manufacturer's specification for an annealed aluminum alloy. A review of the engine logbook was inconclusive as to whether the induction system tubes had been removed for maintenance in the 7.4 years since the engine had been rebuilt. The two separations in the induction system likely caused an imbalance of the intake pressures and the partial loss of engine power during initial climb.



Probable Cause: The two separations in the induction system due to improper installation and/or maintenance, which resulted in a partial loss of engine power during initial climb.
