AD: CFM International, S.A. Turbofan Engines

AD 2022-14-02 Requires The Replacement Of Certain HPT Stage 1 Disks And A Stages 610 Compressor Rotor Spool

The FAA is adopting a new airworthiness directive (AD) for certain CFM International, S.A. LEAP-1A23, LEAP-1A24, LEAP-1A24E1, LEAP-1A26, LEAP-1A26CJ, LEAP1A26E1, LEAP-1A29, LEAP-1A29CJ, LEAP-1A30, LEAP-1A32, LEAP-1A33, LEAP-1A33B2, and LEAP-1A35A (LEAP-1A) model turbofan engines.

This AD was prompted by a manufacturer investigation that revealed that certain high-pressure turbine (HPT) rotor stage 1 disks (HPT stage 1 disks) and a stages 6-10 compressor rotor spool were manufactured from material suspected to contain iron inclusion. This AD requires the replacement of certain HPT stage 1 disks and a stages 610 compressor rotor spool. The FAA is issuing this AD to address the unsafe condition on these products. This AD is effective July 18, 2022. 

Supplementary Information: The FAA was notified by the manufacturer of the detection of iron inclusion in three non-LEAP1A HPT rotor disks. Further investigation by the manufacturer determined that the iron inclusion is attributed to deficiencies in the manufacturing process. The investigation by the manufacturer also determined that certain CFM International, S.A. LEAP-1A HPT stage 1 disks and a stages 6-10 compressor rotor spool manufactured using the same process may have reduced material properties and a lower fatigue life capability due to iron inclusion, which may cause premature fracture and uncontained failure. This condition, if not addressed, could result in uncontained debris release, damage to the engine, and damage to the aircraft. The FAA is issuing this AD to address the unsafe condition on these products.
