## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for Pratt & Whitney (PW) JT8D-1, -1A, -1B, -7, -7A, -7B, -9, -9A, -11, -15, -15A, -17, -17A, -17R, -17AR, -209, -217, -217A, -217C, and -219 turbofan engines. This proposed AD would require removing affected rotating parts overhauled by a certain repair vendor, and inspecting or replacing the parts as applicable. This proposed AD results from reports that certain JT8D critical life-limited rotating parts have been returned to service with cracks, corrosion pitting, or dimensions outside of manual limits. We are proposing this AD to prevent failure of critical life-limited rotating engine parts which could result in an uncontained engine failure and damage to the airplane.
