Cessna 170 N179MM accident near Salt Lake City, Utah

Probable cause

The pilot’s failure to maintain aircraft control during the landing roll.

NTSB analysis

The pilot reported that he started his cross country flight in the tailwheel-equipped airplane in San Antonio, Texas with two rest stops in Roswell and Farmington, New Mexico. When landing to stop for a third time, the pilot checked the airport's automated weather, which indicated a “quartering right crosswind” of about 8 knots. The approach and landing were uneventful. During the landing roll a gust of wind struck the airplane and the airplane initiated a right turn. Despite the pilot’s control inputs the airplane ground looped, collapsing the left main landing gear and substantially damaging the left wing, fuselage and empennage. The pilot reported no mechanical failures or malfunctions with the airframe or engine prior to the accident. The accident airport’s automated weather observation system reported at the time of the accident, wind was from 240 at 13 knots. The pilot’s total flight time for the day was approximately 8.5 hours.
