 CORPORAL JASON MILLER
CORPORAL SCOTT ROBERTSON
In December 2003, Corporals Jason Miller and Scott Robertson, both Aviation Technicians, were performing a routine power turbine change on a GE-T-58-100 Sea King engine. The two technicians had removed the power turbine from the engine and were preparing to install a new one. They noticed that the third stage nozzle had developed cracks along several of the vanes. The third stage nozzle is not part of the power turbine and therefore an inspection in this area of the engine is not called for.
Corporals Miller and Robertson immediately called for the Non-Destructive Testing (NDT) technicians and researched CFTOs to determine if the cracks were within acceptable limits. The NDT results revealed that the cracking on the third stage nozzle was beyond acceptable limits. The unserviceable nozzle was removed from the engine and sent back to the contractor for overhaul.
Corporal Miller and Corporal Robertson both displayed extreme professionalism, attention to detail and initiative, preventing the possible loss of a valuable CF asset. These cracks had the potential for serious or fatal injury if they had not been noticed. Both Corporal Miller, a journeyman, and Corporal Robertson, an apprentice, are commended for their dedication, alertness, and attention to detail in preventing a potentially hazardous in-flight emergency. Their actions warrant this For Professionalism award.
Corporal Miller and Corporal Robertson are still serving with 12 Air Maintenance Squadron, 12 Wing Shearwater.
