## Summary

The FAA proposes to supersede an existing airworthiness directive (AD) for Rolls-Royce Corporation (RRC) AE 3007A and AE 3007C series turbofan engines. That AD currently prohibits any flight following a ground engine start where the engine oil temperature is below 32 [deg]F (0 [deg]C), unless certain preflight operational procedures are followed. This proposed AD would also require those actions, and would also require a terminating action. This proposed AD would supersede the compliance requirements of AD 99-02-51 and all related alternative methods of compliance (AMOCs). This proposed AD results from design improvements to components in the accessory gearbox air turbine starter mounting pad. We are proposing this AD to prevent an in-flight engine shutdown due to loss of engine oil from the starter shaft seal.
