During transition training, the right main landing gear began to collapse on landing rollout. The aircraft veered right, striking a runway exit sign. Damage was consistent with premature gear retraction.

Incident Overview

During a landing rollout, the right main landing gear began to collapse. The aircraft, which was conducting transition training for insurance coverage for the owner, encountered a 5-knot crosswind from the left after touchdown. The pilot applied left aileron to correct for the crosswind. The airplane subsequently veered to the right and contacted a runway exit sign. The flight instructor aborted the landing, and the aircraft made an uneventful landing at its home base.

Damage Assessment

Inspection revealed damage to the inside of the right main tire, the inner landing gear door, the right main gear actuating arm, and the right wheel well aft bulkhead. The damage was consistent with premature retraction of the landing gear.

System Testing

The landing gear was electrically tested, and no mechanical anomalies were noted.
