Maintainers design a $400 maintenance fixture to save the U.S. Air Force $500k per year

2019-04-30

A cowling, or engine cover, is a critical airframe component that reduces drag and directing airflow into the engine. For the E-8C JSTARS, an aircraft with four massive Pratt and Whitney JT3D-based TF33-102C turbofan engines, each set of engine cowling components can cost up to $80,000 per set. Even a slightly warped cowling renders the entire housing unsafe and unserviceable.
