Left Main Gear Collapse During Takeoff Roll

Casualties unknown • Ketchikan, AK, US

Aircraft veered right immediately after takeoff power was applied, resulting in the collapse of the left main landing gear and contact between the left wing and the ground during the initial phase of departure.

What happened

According to statements provided by both the instructor pilot and the private pilot involved, the incident occurred shortly after takeoff power was added to the engine. Immediately following this action, the airplane began to veer sharply to the right side of the runway. This directional deviation led directly to the structural failure of the left main landing gear, which subsequently collapsed under the stress of the off-center load.

As the aircraft continued its uncontrolled movement, the left wing made contact with the ground surface. At the time these events unfolded, both pilots were actively sharing control of the aircraft. The crew later explained that they were attempting to expedite their departure because an airline jet was waiting behind them for clearance to use the same runway.

Findings

The sequence of events indicates a loss of directional control during the critical takeoff phase. The initial veering to the right suggests a potential asymmetry in thrust or a braking issue, which overwhelmed the pilots' ability to maintain the centerline. The subsequent collapse of the left main gear was a direct consequence of this lateral deviation and the resulting ground contact forces.

Safety message

While external pressure from other traffic can create urgency, maintaining strict adherence to standard takeoff procedures is essential. Pilots must prioritize aircraft control and runway alignment over schedule pressures, especially during the high-energy phase of departure where structural integrity is vulnerable to asymmetric loads.
