We are issuing this AD to prevent fracture of the first- stage PT blade, possible engine fire, and damage to the airplane. (e) Actions and Compliance Unless already done, within 60 months after the effective date of this AD or when the affected PT blades are at module level exposure, whichever occurs first, do one of the following: (1) Replace the affected first-stage PT blade with a blade eligible for installation; or (2) Perform a one-time X-ray inspection of the affected first- stage PT blades, using paragraph 3.F.(2) of the Accomplishment Instructions of P&WC Service Bulletin No. PW100-72-21823, Revision 3, dated March 8, 2013. (f) Installation Prohibition After the effective date ofthis AD, do not install into any engine any first-stage PT blade that has not passed the inspection required by paragraph (e)(2) of this AD.
