Pitcairn PA-18, N12680: Accident occurred November 18, 2016 at Northeast Philadelphia Airport (KPNE), Philadelphia, Pennsylvania

Additional Participating Entity: 
Federal Aviation Administration / Flight Standards District Office; Philadelphia, Pennsylvania 

Aviation Accident Factual Report - National Transportation Safety Board: https://app.ntsb.gov/pdf


NTSB Identification: GAA17CA092
14 CFR Part 91: General Aviation
Accident occurred Friday, November 18, 2016 in Philadelphia, PA
Aircraft: PITCAIRN PA 18, registration: N12680
Injuries: 1 Uninjured.

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

According to the pilot of the tailwheel-equipped gyroplane, he landed on the right main landing gear. The gyroplane begin rolling to the right, but the gyroplane's heading was aligned to the left of the runway heading and continued in a left direction of travel. He attempted to correct the gyroplane's right roll by moving the control stick to the left, however, the aileron movement did not subside the roll. He reported that in hindsight, opening the throttle and right rudder application may have subsided the roll, "but my mental preparedness was biased to preventing a ground loop, not a dynamic rollover". However, the gyroplane continued to roll right and impacted the ground. The gyroplane came to rest on the runway and sustained substantial damage to the main rotor system, right wing, and the empennage.

The pilot reported that his lack of experience in the gyroplane model contributed to the accident, because the critical angle was exceeded in this gyroplane more quickly than other gyroplanes that he was accustomed to flying.

The pilot reported that there were no pre-accident mechanical malfunctions or failures with the gyroplane that would have precluded normal operation.
