 Hi, I'm 83 Leo Barth and I'm an aviation machinist mate and test cell operator in the jet shop onboard Big E. My job is to repair and test jet engines for the F-18 Hornet and Super Hornet aircraft. Before testing we look over the motor and test equipment to ensure it is all properly installed and restrained. During testing several leak checks are performed to be sure no fuel, oil or air is escaping. Leak checking is the most exciting part of our job because it's done while operating at maximum speeds of over 17,000 RPM and with a 15 foot flame coming from the exhaust. Once testing is complete for the motor it's ready for use by the squadrons.
