As he was maneuvering around the traffic pattern, he initially planned a wheel landing, where the main landing gear touch down first, followed later with the tail wheel settling down on the runway. During touchdown, he did not add sufficient power and decided to transition to a three-point landing, in which all three landing gear touch down simultaneously. The airplane bounced upon touchdown, and he briefly lost visual sight of the runway. The airplane touched back down again with the nose pointed left of the runway centerline. Despite the pilot’s attempts to regain directional control, the airplane departed the left side of the runway into a dirt area. The right main gear dug into the terrain and the airplane nosed over. During the accident sequence, the airplane sustained damage to the right wing. The pilot reported that the airplane had no pre impact mechanical malfunctions or failures that would have precluded normal operation. ## Aircraft - Registration: [N686X](https://openairdocs.org/aircraft/N686X), registered now, S/N 207 (OpenAirDocs) - Reported make and model: WEAVER Harmon Rocket - Registry model: [Weaver Fred A HR II](https://openairdocs.org/model/weaver-fred-a-hr-ii) (registry code 05614PQ) (OpenAirDocs) - Registry engine: [Amateur-built UNKNOWN ENG](https://openairdocs.org/engine/amateur-built-unknown-eng) (registry code 99999) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 207 - Year built: 2003 - Airframe hours: 415 - Engines: Lycoming IO-540 316 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Special, Experimental (Special) - Last inspection: Annual, May 4, 2025 - Destination: Same as departure - Airport: COE, Pappy Boyington Field, runway 02/20, 5,400 × 75 ft, asphalt - Equipment: Satellite tracking device, Electronic primary flight display, Electronic multifunction display, Data recorder, Auto-pilot, ADS-B ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
