FAA Orders Fixes After Engine Blades Cause Fires

## Summary

The FAA is making important safety fixes for certain International Aero Engines models after some fan blades broke and caused fires. Starting February 17, 2026, affected engines must have parts removed, replaced, and reinstalled to keep flights safe. This update helps prevent engine fires and keeps planes flying smoothly, with maintenance costs expected but worth the safety boost.

## Abstract

The FAA is adopting a new airworthiness directive (AD) for all International Aero Engines, LLC (IAE LLC) Model PW1122G-JM, PW1124G-JM, PW1124G1-JM, PW1127G-JM, PW1127G1-JM, PW1127G1A-JM, PW1127G1B-JM, PW1127GA-JM, PW1129G-JM, PW1130G-JM, PW1133G-JM, PW1133GA-JM, PW1428G- JM, PW1428GA-JM, PW1428GH-JM, PW1431G-JM, PW1431GA-JM, and PW1431GH-JM engines. This AD was prompted by multiple reports of fan blade fracture events, three of which resulted in an engine under cowl fire or pool fire. This AD requires removal of one loop cushion clamp from the hydraulic fuel pressure fuel oil cooler fuel tube assembly (CP09 tube assembly), replacement of the thermal management system (TMS) clevis mounts with redesigned TMS clevis mounts, and reinstallation of the loop cushion clamp, as applicable. The FAA is issuing this AD to address the unsafe condition on these products.

## Effects PRIA read

- Stops engine fires from blade fractures: benefit, high. The FAA requires changes to certain International Aero Engines models after multiple fan blade fractures, three of which caused engine under-cowl or pool fires. The AD is intended to prevent a fuel leak from a fan blade fracture and avoid an uncontrolled engine fire or airplane damage, and is effec…
- Required maintenance actions and timing: cost, medium. Beginning February 17, 2026, operators of affected IAE engine models must remove one loop cushion clamp (part number ST1540-06) within 30 days after the effective date or on installation, and must replace the thermal management system (TMS) clevis mounts with redesigned mounts at the next engine sh…
- Estimated per-engine and national compliance costs: cost, high. The FAA estimates costs per engine: $765 to remove the loop cushion clamp, $26,095 to replace the TMS clevis mounts (labor $9,095 plus $17,000 parts), and $765 to reinstall the clamp. The FAA estimates this AD affects 586 U.S.-registered engines, with estimated costs to U.S. operators of $448,290 f…
- Allows reuse of certain bolts if inspected: benefit, low. The FAA agreed to allow certain part-numbered bolts to be reused if they pass the specified inspections and procedures in the updated service material. The AD references PW Alert Service Bulletin PW1000G-C-72-00-0214-00A-930A-D, Issue No. 006, dated August 19, 2025, and provides credit for earlier…
- Definition of 'engine shop visit' includes quick-turns: cost, low. The AD defines an 'engine shop visit' as the induction of an engine into the shop for maintenance and states that quick-turn shop visits are considered engine shop visits for this rule. Operators may request an AMOC if they can justify an alternative approach.
