On November 28, 2002, a Cessna 170B (registration N4465B) was involved in an aviation accident near Mobile, AZ. Investigators recorded the probable cause as: the pilot's improper compensation for the crosswind conditions at touchdown and failure to maintain proper alignment of the tail wheel equipped airplane during landing, which resulted in a ground loop. The crosswind was a contributory factor. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During touch-and-go practice at an abandoned gravel airstrip, the airplane ground looped and nosed over after a crosswind diminished on final approach.
Accident Sequence
The pilot was performing touch-and-go practice takeoffs and landings at an abandoned gravel airstrip. During the approach, the pilot configured the airplane in a crab to the right to counteract a right-quartering crosswind. On final approach, approximately 15 feet above ground level, the crosswind diminished.
The airplane touched down on the runway surface while still in the right crab, with the right main landing gear making initial contact. The airplane then veered to the left, departing the edge of the runway. Subsequently, the main landing gear impacted a dirt berm, resulting in a nose over. The airplane came to rest inverted.
Pilot Report
The pilot reported no pre-impact mechanical malfunctions or failures with the airplane.
