He noted that the go-around was conducted in conditions that reduced the airplane's performance margin as he was operating at a low altitude, low airspeed, and a high gross weight. During the go-around, the airplane encountered shifting wind conditions and drifted left of the runway centerline. As the pilot attempted to correct the drift while establishing a climb, he exceeded the airplane’s critical angle of attack and entered an aerodynamic stall. The airplane subsequently impacted the ground, which resulted in substantial damage to the fuselage, wings, and empennage. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N135DS](https://openairdocs.org/aircraft/N135DS), registered now, S/N 30, built 2001 (OpenAirDocs) - Reported make and model: Moose SR 2500 - Registry model: [Shaw Donald W MURPHY SUPER REBEL](https://openairdocs.org/model/shaw-donald-w-murphy-super-rebel) (registry code 05610HG) (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: 30 - Year built: 2001 - Airframe hours: 486 - Engines: Lycoming O-540 260 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Special, Experimental (Special); Standard, Normal - Last inspection: Annual, May 2, 2025 - Departed: AUN, Auburn, CA - Destination: Same as departure - Airport: 0Q3, Sonoma Valley Airport, runway 25, 2,700 × 45 ft, asphalt - Equipment: 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. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
