Summary
On July 28, 2017, a Mark Goldberg BEARHAWK PATROL (N410BP) was involved in an incident near Oshkosh, WI. All 2 people aboard were uninjured. The aircraft sustained substantial damage.
The National Transportation Safety Board determined the probable cause of this incident to be: The pilot's failure to maintain directional control during the landing roll in crosswind conditions, which resulted in a ground loop.
The pilot of the tailwheel-equipped airplane reported that, during the landing roll in crosswind conditions, when "transitioning from rudder to braking the tail started rapidly swinging to the left due to wind." He added that "rudder correction was ineffective" and he applied wheel brakes, but the airplane continued in the ground loop clockwise, the left main landing gear collapsed, and the left wing impacted the runway.
The left wing sustained substantial damage.
The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
An automated weather observation station, about the time of the accident, at the accident airport, reported wind from 040° at 8 knots.
This incident is documented in NTSB report GAA17CA451. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N410BP.
