Christen A-1, N9598Z: Accident occurred January 09, 2017 in Milton-Freewater, Umatilla County, Oregon

Aviation Accident Factual Report - National Transportation Safety Board:

FAA Flight Standards District Office: Spokane

NTSB Identification: GAA17CA110
14 CFR Part 91: General Aviation
Accident occurred Monday, January 09, 2017 in Milton-Freewater, OR
Aircraft: CHRISTEN INDUSTRIES INC A 1, registration: N9598Z
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.

The pilot of a tailwheel-equipped airplane reported that while en route the engine had "slight roughness," so he decided to land in an open snow covered field on top of a hill to troubleshoot the issue. The pilot further reported that he was able to resolve the engine issue on the ground and decided to takeoff downhill with a tailwind. During the takeoff roll, the pilot reported that he "noticed [wind] gust on the tail," the main landing gear were "sucked down" in a one-foot snow drift, and the airplane nosed over.

The left wing, fuselage, and vertical stabilizer sustained substantial damage.

The pilot did not report any preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
