The defining event best describes what happened. - [Landing-landing roll: Loss of control on ground](https://openairdocs.org/ntsb-events/230) (defining event); cases with it: [Piper PA-18A 150, 11 cases](https://openairdocs.org/ntsb-events/230/sequence.md?model=7101837), [All aircraft, 4,585 cases](https://openairdocs.org/ntsb-events/230/sequence.md) ## Analysis The pilot stated that she was flying the airplane from the front seat, and the airplane owner (who is also a pilot) was in the rear seat. The pilot in the front seat turned final early to maintain aircraft separation and made a short and slightly steep final approach. She said that while landing she flared the airplane a little high, and it bounced twice during the landing. During the second bounce, the pilot in the rear seat assisted the recovery by applying corrective input. The pilot in the front seat could not recall if she continued to apply control inputs or if the pilot in the rear seat had assumed the controls. Positive control transfer was not accomplished. The airplane ground looped to the right, substantially damaging the left wing when the wing tip struck the runway. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The pilot stated that she was flying the airplane from the front seat, and the airplane owner (who is also a pilot) was in the rear seat.
