On August 1, 2003, a Cessna 170 (registration N3418C) was involved in an aviation accident near Anchorage, AK. Investigators recorded the probable cause as: The pilot's inadequate compensation for a crosswind condition and his failure to maintain directional control of the airplane that resulted in the left wing contacting the runway surface during the landing roll. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A private pilot practicing tailwheel landings experienced a bounce and crosswind lift, resulting in left wing contact with the runway and a ground loop. Damage required replacement of two left wing ribs and the left aileron.
Accident Overview
A private pilot holding a tailwheel endorsement was practicing landings in a tailwheel-equipped airplane at various airports. During the accident landing, the pilot reported a right crosswind of 10 to 12 knots. The airplane bounced on touchdown, and the right wing was lifted by the wind. The pilot attempted to correct the bounce with rudder input, but the left wing contacted the runway surface, causing the airplane to ground loop.
Post-Accident Findings
After the incident, a mechanic examined the airplane and determined that two outboard wing ribs of the left wing and the left aileron required replacement due to damage sustained during the ground loop.
