Cessna 172 Ground Loop Results in Landing Gear Collapse

Casualties unknown • Talkeetna, AK, US

A Cessna 172 experienced a ground loop during landing rollout on runway 01 due to crosswind correction, causing the right main gear to collapse and substantial damage to the airframe.

What happened

The pilot, holding a commercial certificate, was operating a single-engine aircraft with one passenger aboard. The flight phase involved landing on runway 01, which necessitated rudder input to counteract a slight left crosswind component. Upon touchdown, during the initial rollout, the airplane began to veer toward the right side of the runway.

To correct this deviation, the pilot applied left rudder in coordination with braking on the left main wheel. Despite these control inputs, the aircraft subsequently ground looped sharply to the left. The impact forces caused the right main landing gear to collapse. Following the collapse, the right wing struck the airstrip surface, resulting in substantial damage to the airframe.

The investigation

Post-acc examination of the aircraft revealed no pre-existing mechanical anomalies that would have contributed to the incident. The pilot confirmed that the airplane was operating normally prior to the landing sequence. The primary failure mode was structural damage induced by the ground loop dynamics rather than a system malfunction.

Findings

The accident occurred during the landing phase of flight at an uncontrolled airstrip. Weather conditions included a slight left crosswind, which required active correction by the pilot. The Cessna 172 (registration N98SW) sustained substantial damage to the right wing and landing gear assembly. The pilot reported not injured, and the passenger was also not injured. The causal factor was the loss of directional control during rollout, leading to a ground loop.

Safety message

Pilots operating tailwheel or conventional gear aircraft in crosswind conditions must remain vigilant for directional control issues during the landing roll. Proper use of rudder and differential braking is critical to prevent ground loops, which can result in severe airframe damage even without mechanical failure.

Probable cause

The pilot's loss of directional control during the landing rollout, which resulted in a ground loop and subsequent collapse of the right main landing gear.
