NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
In a postaccident interview, the pilot reported that he did not remember taxiing out for takeoff with the right passenger door open but that he did remember that the right door was open after takeoff and that he advised the control tower operator of his intention to return to the airport. The pilot recalled that, during the return maneuver, there was a vibration, as if the door had come off and struck the rear-mounted propeller, which prompted him to make an emergency landing on a nearby golf course. A witness at the airport reported seeing the right passenger door open during taxi and takeoff.
The right passenger door was located about 1 mile west-southwest of the accident site. A postaccident examination revealed that the door’s locking mechanism was intact and that the lower forward section of the door showed black rubber signature marks that were consistent with contact with the engine drive belt, which was found separated from the engine. Additionally, the cambered surfaces of each of the three propeller blades exhibited rubber impact marks. A postaccident examination of the airframe and engine did not reveal any preaccident anomalies that would have precluded normal operation. A flight instructor reported that, during a postaccident conversation, the pilot told him that he simply missed locking the copilot door and that this resulted in the separation of the door from the airframe.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot did not close and secure the right passenger door, which resulted in an in-flight separation of the door and subsequent loss of engine power due to the door’s collision with the rear-mounted engine assembly.
