The FAA is adopting a new airworthiness directive AD for all Pratt & Whitney PW PW2037, PW2037M, PW2040, and F117PW100 model turbofan engines. This AD was prompted by a report of an uncontained engine failure resulting from cracks in the knife edge of the high-pressure turbine HPT 2nd-stage air seal assembly. This AD requires fluorescent penetrant inspections FPIs and visual inspections of the HPT 2nd-stage air seal assembly and, depending on the results of the inspections, replacement of the HPT 2nd-stage air seal assembly with a part eligible for installation. This AD also requires replacement of the affected HPT 2nd-stage air seal assembly, depending on the engine model, at either the next engine shop visit or the next piece-part opportunity.
The FAA is issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective September 1, 2021.

SUPPLEMENTARY INFORMATION:
Background The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 by adding an AD that would apply to all PW PW2037, PW2037M, PW2040, and F117PW100 model turbofan engines. The NPRM published in the Federal Register on June 1, 2020
85 FR 33043. The NPRM was prompted by a report of an uncontained engine failure resulting from cracks in the knife edge of the HPT 2nd-stage air seal assembly. After further analysis, it was determined that the knife-edge crack was due to seal rubbing that elevated the HPT 2nd-stage air seal assembly temperature and induced fatigue. In the NPRM, the FAA proposed to require initial and repetitive borescope inspections BSIs, FPIs, and visual inspections of the HPT 2nd-stage air seal assembly and, depending on the results of the inspections, replacement of the HPT 2nd-stage air seal assembly with a part eligible for installation. The NPRM also proposed to require replacement of the affected HPT 2ndstage air seal assembly, depending on the engine model, at either the next engine shop visit or the next piece-part opportunity. The FAA is issuing this AD
to address the unsafe condition on these products.
