FAA Orders Extra Inspections for Wobbly International Aero Engines
Published Date: 9/5/2025
Rule
Summary
The FAA is making new rules for certain International Aero Engines to keep them safe after a serious engine part broke and caused damage. If you own or work with these engines, you’ll need to update your maintenance manuals and do extra inspections on key parts. These changes help prevent dangerous failures and keep flights safe, with updates required soon to avoid costly problems later.

Mandatory Maintenance Manual Revisions
The FAA requires owners/operators of certain International Aero Engines (models V2522-A5, V2524-A5, V2525-D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, V2531-E5, and V2533-A5) to revise the airworthiness limitations section (ALS) of maintenance manuals or instructions for continued airworthiness and to revise approved maintenance/inspection programs to include new inspections of certain critical rotating parts.
Reduces Risk of Uncontained Engine Failures
The AD responds to an event where an IAE AG Model V2533-A5 engine had an uncontained failure of a high-pressure turbine (HPT) 1st-stage hub that sent high-energy debris through the engine cowling. The new required inspections aim to prevent similar HPT 1st-stage hub failures and help keep flights safer.
