Swearingen SA227 N561UP accident near Rock Springs, Wyoming

Probable cause

The pilot's failure to maintain directional control while taxiing in gusting tailwind conditions.

NTSB analysis

The pilot reported that, while taxiing with a tailwind, he realized that the airplane was moving too fast and that he then applied brakes and reverse engine thrust. He added that he attempted to turn the airplane but was unable to do so and that a strong crosswind "forced" the airplane to the left and off the airport parking ramp. Subsequently, the airplane struck a lamp post and came to rest.

The airplane sustained substantial damage to the left wing.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

The automated weather observation system located at the airport reported that, about the time of the accident, the wind was from 280° at 21 knots, gusting to 27 knots.
