## Summary

We propose to adopt a new airworthiness directive (AD) for Rolls-Royce Corporation (RRC) AE 2100D2A and AE 2100D3 model turboprop engines and AE 3007A2 model turbofan engines. This proposed AD was prompted by the possibility of a low-cycle fatigue failure on certain turbine wheels. This proposed AD would require removing the affected turbine wheels at the next engine shop visit or before reaching the new reduced life limit, whichever occurs first, and replacing them with parts eligible for installation. We are proposing this AD to address the unsafe condition on these products.
