On October 25, 1996, a Cessna 170B (registration N2419D) was involved in an aviation accident near Utica, MT. Investigators recorded the probable cause as: The pilot's improper use of the brakes, while landing a tailwheel aircraft in crosswind conditions. The crosswind was a related factor. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During a full-stall landing in a left crosswind, a pilot's aggressive right brake caused a wheel lock, leading to a directional swing; subsequent left brake application resulted in the aircraft nosing over.
Incident Overview
While attempting a full-stall landing in a left crosswind, the pilot experienced a directional deviation. As the aircraft's nose began to swing into the wind, the pilot applied the right brake with significant force. This action caused the right wheel to lock, and the aircraft immediately started to swing in the opposite direction.
Sequence of Events
Without releasing the right brake, the pilot then applied the left brake with enough force that the aircraft nosed over. The braking inputs resulted in a loss of directional control and a subsequent nose-over event.
Contributing Factors
No contributing factors beyond the described brake applications were identified in the source material.
