Probable cause

The partial loss of engine power for reasons that could not be determined based on the available information, which resulted in the forced landing attempt and impact with power lines.

NTSB narrative

The pilot reported that, after departing on the personal flight, he observed that the manifold pressure was low and the airplane performance was poor. The engine began running roughly and lost partial power. The pilot maneuvered the airplane for an emergency landing on a nearby highway. During the descent, the airplane impacted power lines, then impacted the ground and came to rest vertically against a grove of trees along the highway. The airplane sustained substantial damage to the fuselage. Examination of the engine, engine accessories, and airframe did not reveal evidence of any preaccident mechanical malfunctions or failures that would have precluded normal operation. The propeller assembly showed blade damage consistent with some degree of rotation at impact; however, the amount of power to the propeller could not be determined. Based on fueling documents provided and the pilot's statements, there was likely sufficient quality fuel for the engine to operate normally. The reason for the loss of partial engine power could not be determined.
