What the agency says
The FAA is adopting a new airworthiness directive (AD) for certain International Aero Engines, LLC (IAE) Model PW1124G1-JM, PW1127G-JM, PW1127GA-JM, PW1129G-JM, PW1130G-JM, PW1133G-JM, and PW1133GA-JM engines. This AD was prompted by a report that certain high-pressure compressor (HPC) 2nd stage rotors and HPC 4th stage rotors have potentially degraded knife-edge seals and abrasive coating of the rear wing 4th stage rotor due to having been cleaned in alkaline solution without masking the knife-edge seal coating. Operating in this condition could result in material degradation and fracture of the HPC 2nd stage rotor and HPC 4th stage rotor. This AD requires replacement of certain HPC 2nd stage rotors and HPC 4th stage rotors. The FAA is issuing this AD to address the unsafe condition on these products.
