NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

As the pilot leveled the airplane at 2,500 ft mean sea level during the descent for landing, he advanced the throttle but observed no response from the engine. He could not restore engine power; however, the propeller continued to spin. He noted that the throttle “felt very loose” when he attempted to add power. The airplane was unable to maintain altitude, so the pilot performed a forced landing in a field. The airplane collided with trees before coming to rest in the field, which resulted in structural damage to the airframe and minor injuries to the occupants.
During a postaccident examination of the airframe and engine, the portion of the engine throttle cable that was normally clamped just forward of the upper right engine firewall was found forward of and unclamped from its clamping device. Examination of the remainder of the wreckage did not reveal evidence of a mechanical malfunction or failure. It is likely that the throttle cable became unsecured during the flight and led to the lack of throttle response reported by the pilot.


The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
  • A loosening of the engine throttle cable from its support clamp during flight, which resulted in a loss of throttle control.
