Abstract
The FAA is adopting a new airworthiness directive (AD) for International Aero Engines (IAE) V2500 series turbofan engines. This AD requires repetitive monitoring of N2 vibration on all IAE V2500 series engines to identify engines that might have a cracked high pressure turbine (HPT) stage 2 air seal. This AD results from a report that HPT stage 2 air seals have developed cracks. We are issuing this AD to prevent uncontained failure of the HPT stage 2 air seal.
