I worked in the depot at Warner Robins for many years in various aspects of the 54H60 overhaul line. Now I am the primary Equipment Specialist for the prop, APU/GTC, and fire detection/protection systems at Robins. I am also secondary on the engine. I also have the same responsibilities for the J Model systems. Dowty R391, RR AE2100D3 etc. I have a lot of respect for the Herks!
