What happened
While on final approach to the runway, the pilot reported to the tower controller a loss of engine power, and that he was attempting to make the runway. Shortly thereafter, the airplane collided with power lines in a residential area about 175 ft short of the runway threshold. A postaccident fire consumed the wreckage.
Postaccident examination of the wreckage revealed that the engine’s throttle control rod was separated from the throttle body control arm. None of the attachment hardware, which comprised of a bolt, washer, castellated nut, and cotter pin, was found. Additionally, no evidence of impact damage was noted in the throttle lever linkage control rod end or the control arm where it attached. The airplane’s most recent annual inspection was 78 flight hours and about 2 months before the accident. During the inspection, a new engine was installed. Based on the available information, it is likely that the throttle control connecting hardware was improperly installed or secured during the most recent maintenance, which resulted in its disconnection and a loss of engine power and throttle control while on final approach.
