SUPPLEMENTARY INFORMATION:

Examining the AD Docket
Background On March 18, 2020, an Airbus Model A321231 airplane, powered by IAE
V2533A5 model turbofan engines, experienced an uncontained HPT 1ststage disk failure that resulted in highenergy debris penetrating the engine cowling. Based on a preliminary analysis of this event, on March 21, 2020, the FAA issued Emergency AD
20200751 followed by publication in the Federal Register on April 13, 2020, as a Final Rule, Request for Comments 85 FR 20402, which requires the removal from service of certain HPT 1ststage disks installed on IAE V2522A5, V2524A5, V2525D5, V2527A5, V2527EA5, V2527MA5, V2528D5, V2530A5, and V2533A5 model turbofan engines.
Pratt & Whitney PW determined that the failure of the V2533A5 model turbofan engine was due to an undetected subsurface material defect in an HPT disk that may affect the life of the part. In June 2021, PW expanded its root cause analysis to include a review of records for all other IAE and PW
engines that contain parts of similar material.
On July 29, 2021, PW provided its PW1100G analysis results to the FAA.
PWs analysis identified a different population of HPT 1st-stage and HPT
2nd-stage disks installed on IAE
PW1122GJM, PW1124G1JM, PW1124GJM, PW1127G1JM, PW1127GAJM, PW1127GJM, PW1129GJM, PW1130GJM, PW1133GAJM, and PW1133GJM
model turbofan engines that are also affected by the unsafe condition in AD
20200751 and require removal from service. This condition, if not addressed, could result in uncontained HPT disk failure, release of high-energy debris, damage to the engine, damage to the airplane, and loss of the airplane.
The FAA is issuing this AD to address the unsafe condition on these products.

You may examine the AD docket at https www.regulations.gov by searching for and locating Docket No.
FAA20210780; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal
FAAs Determination The FAA is issuing this AD because the agency has determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.

Federal Aviation Administration FAA, DOT.
ACTION: Final rule; request for comments.
AGENCY:

The FAA is adopting a new airworthiness directive AD for certain International Aero Engines, LLC IAE
PW1122GJM, PW1124G1JM, PW1124GJM, PW1127G1JM, PW1127GAJM, PW1127GJM, PW1129GJM, PW1130GJM, PW1133GAJM, and PW1133GJM
model turbofan engines. This AD was prompted by a root cause analysis of an event involving an uncontained failure of a high-pressure turbine HPT disk that resulted in high-energy debris penetrating the engine cowling on an Airbus Model A321231 airplane, powered by IAE V2533A5 model turbofan engines. This AD requires removing certain HPT 1st-stage and HPT
2nd-stage disks from service. The FAA
is issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective September 27, 2021.
The FAA must receive comments on this AD by October 25, 2021.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
