## Summary

We propose to adopt a new airworthiness directive (AD) for certain Pratt & Whitney Canada Corp. (P&WC) PW118A, PW118B, PW119B, PW119C, PW123, PW123B, PW123C, PW123D, PW123E, PW123AF, PW124B, PW125B, PW126A, PW127, PW127E, PW127F, PW127G, and PW127M turboprop engines. This proposed AD was prompted by reports of fractures of the 1st stage power turbine (PT) blade. This proposed AD would require inspection of the 1st stage PT blades and the removal from service of those blades that fail the inspection or their replacement with blades eligible for installation. We are proposing this AD to prevent fracture of the 1st stage PT blade, possible engine fire, and damage to the airplane.
