Summary
We propose to adopt a new airworthiness directive (AD) for certain International Aero Engines AG (IAE), V2525-D5 and V2528-D5 turbofan engines, with a certain number (No.) 4 bearing internal scavenge tube and a certain No. 4 bearing external scavenge tube installed. This proposed AD was prompted by a report of an engine under-cowl fire and commanded in-flight shutdown. This proposed AD would require replacement of certain part number (P/N) No. 4 bearing internal scavenge tubes, and alignment checks of certain P/N No. 4 bearing external scavenge tubes. We are proposing this AD to prevent engine fire and damage to the airplane.
