1989-02-25: Stinson 108-1 (N97764) — Albany, OR

Albany, OR, US

On February 25, 1989, a Stinson 108-1 (registration N97764) was involved in an aviation accident near Albany, OR. Investigators recorded the probable cause as: The student pilot's improper use of flight controls during a crosswind landing, specifically using rudder instead of aileron to correct a wing drop, which resulted in a swerve, left wingtip drag, and main gear failure. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A student pilot experienced a landing gear failure and nosed-over incident during a crosswind solo landing when incorrect control inputs caused the aircraft to swerve off the runway.

What happened

The accident occurred while a student pilot was conducting their first solo flight. During the landing phase, the aircraft encountered significant crosswind conditions. Upon touchdown, the plane touched down on the left side of the runway. As the left wing dropped due to the wind, the pilot attempted to correct the attitude by applying right rudder instead of using the ailerons. This incorrect control input caused the aircraft to swerve sharply to the right.

During this uncontrolled swerve, the left wingtip struck the ground. The impact caused the left main landing gear to fail structurally. With the loss of support on that side, the aircraft departed the paved surface and continued forward until it nosed over.

The investigation

Examination of the event focused on the pilot's control inputs during the critical phase of landing in crosswind conditions. The sequence of events indicated that the initial touch-down position was off-center to the left. The subsequent failure of the left main gear was a direct result of the wingtip dragging and the resulting mechanical stress from the swerve.

Findings

The primary factor contributing to the accident was the pilot's improper use of flight controls during a crosswind landing. Specifically, the student relied on rudder input rather than aileron correction to manage the wing drop. This technique failure led to the loss of directional control, ground contact with the wingtip, and subsequent structural failure of the landing gear.

Probable cause

The student pilot's improper use of flight controls during a crosswind landing, specifically using rudder instead of aileron to correct a wing drop, which resulted in a swerve, left wingtip drag, and main gear failure.
