| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot stated that during the landing rollout the right main landing gear collapsed, and the airplane exited the runway. Company maintenance personnel examined the right gear and found that a dynamic brake relay, which provides a momentary surge of reverse current to the right main landing gear for positive stopping was defective. This defective part allowed the motor to drive the gearbox past prescribed limits, inducing a bend into the right main landing gear connecting rod. Once gear down was selected, the rod was placed under a compression load, which caused it to bend even further, and not extend the gear.
Probable Cause: failure of the right main landing gear's dynamic brake relay, that resulted in the motor driving the gearbox past prescribed limits, resulting in a bent connecting rod, and failure of the gear to extend.
