Accident Number: WPR20CA036

Registration: N864SC
Aircraft: JAVRON PA-18 Replica
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Personal

The pilot stated that he was planning to perform an off-airport landing on the shore of a reservoir where he had successfully landed many times before. After an approximate 30-minute flight, the pilot configured the airplane for landing on the shoreline. During touchdown, the passenger, who was positioned in the rear-seat, inadvertently applied the brakes. Because of the brakes being depressed on touchdown, the airplane immediately nosed-over coming to rest inverted.

The airplane sustained substantial damage to the wing strut.

The pilot reported that there were no preimpact mechanical anomalies with the airplane that would have precluded normal operation.

  1. Beautiful plane, scenic location. Then: "During touchdown, the passenger, who was positioned in the rear-seat, inadvertently applied the brakes.".
    The heart breaks just to read about this one. Glad they walked away, hope that bird gets fixed and back to service.
