FAA issues emergency AD following Vietnam Airlines A321 uncontained IAE V2533 engine failure
22 March 2020

The U.S. FAA issued an emergency airworthiness directive following an uncontained engine failure of an IAE V2533-A5 engine of an Airbus A321.

On March 18, Vietnam Airlines flight VN920, an Airbus A321-231, powered by IAE V2533-A5 model turbofan engines, experienced an uncontained high-pressure turbine (HPT) 1st-stage disk failure on takeoff from Ho Chi Minh City-Tan Son Nhat Airport in Vietnam. The flight crew aborted the takeoff.

As a result of this occurrence, the FAA issued an emergency AD on March 21, 2020, requiring removal from service of affected HPT 1st-stage disks with specific part numbers, installed on IAE V2500 engine models. The FAA considers this an interim action as the root cause of this incident is still under investigation.
