Aviation Accident Data Summary - National Transportation Safety Board: 

NTSB Identification: WPR14CA277
14 CFR Part 91: General Aviation
Accident occurred Tuesday, July 01, 2014 in Hysham, MT
Probable Cause Approval Date: 09/30/2014
Aircraft: JONES HATZ CB1, registration: N39761
Injuries: 2 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 reported that after returning back from an approximate 45-minute local flight, he aligned the tailwheel equipped bi-plane for a landing on the active runway. The pilot noted there was an approximate 10-knot crosswind. During the landing roll, the airplane veered right and continued off the runway surface. The airplane ground looped which resulted in the collapse of the landing gear. As a result of the impact, the airplane incurred substantial damage to the wings. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot's failure to maintain directional control during the landing roll with a crosswind, which resulted in a ground loop.
