Summary
We propose to adopt a new airworthiness directive (AD) for all International Aero Engines AG (IAE) V2525-D5 and V2528-D5 model turbofan engines. This proposed AD was prompted by reports of cracked turbine exhaust cases (TECs). This proposed AD would require initial and repetitive inspections of the affected TEC and, depending on the results of the inspections, its replacement with a part eligible for installation. We are proposing this AD to address the unsafe condition on these products.
