What to do
Affected operators must remove and replace the identified low-pressure turbine 1st- and 3rd-stage disks with eligible parts by the next piece-part exposure, not exceeding 2,240 cycles since new for 1st-stage disks and 4,800 cycles since new for 3rd-stage disks. The initial removal must occur within 30 days after the AD's effective date or later as specified. Stakeholders should coordinate with the FAA for any alternative methods of compliance if needed.
Summary
FAA Airworthiness Directive 2018-24-01 is a final rule addressing certain International Aero Engines PW1100G-JM turbofan engine models equipped with specific low-pressure turbine 1st- and 3rd-stage disks. The directive mandates removal and replacement of these disks due to manufacturing defects that could lead to unsafe engine conditions. This AD applies to multiple PW1100G-JM variants including PW1133G-JM, PW1133GA-JM, PW1130G-JM, PW1127G-JM, PW1127GA-JM, PW1127G1-JM, PW1124G-JM, PW1124G1-JM, and PW1122G-JM engines.
What changed
This new airworthiness directive requires removal from service and replacement of affected low-pressure turbine 1st- and 3rd-stage disks identified by serial numbers. The compliance requirement was updated from removal at the next shop visit to removal at the next piece-part exposure, with specific cycle limits for each disk stage. The AD introduces mandatory corrective actions to mitigate risks associated with manufacturing defects in these engine components.
Why it matters
This AD is critical for aviation professionals because it addresses a potential uncontained disk failure that could cause engine damage and compromise aircraft safety. Operators and maintenance organizations must ensure timely compliance to avoid unsafe conditions and maintain regulatory compliance. The directive also clarifies compliance timing to balance safety with operational flexibility during maintenance.
