Master Corporal Gouthro, an Aviation Technician at 403 Squadron, was performing an end-of-day check on a Griffon aircraft. A recent arrival on Squadron, Master Corporal Gouthro was not yet authorized on type and a qualified technician was observing his work. During his inspection of the swashplate assembly Master Corporal Gouthro noticed that there appeared to be no jam-nut on the link assembly. As Master Corporal Gouthro was aware that all rod-ends had to be secured he elected to investigate for further evidence of a locking system. His survey revealed that there was indeed a locking-nut, but that it had backed-off, was out of normal view, and had therefore been overlooked on previous inspections. He immediately advised his supervisor and the aircraft was grounded. Though inexperienced on the Griffon, Master Corporal Gouthro displayed outstanding professionalism in finding an impending threat to flight safety and in preventing what could have been a catastrophic failure of the main rotor-head assembly. |
