FAA Emergency Airworthiness Directive 2020-07-51

On March 18, 2020, Vietnam Airlines flight VN920 from Ho Chi Minh City (Vietnam) to Phnom Penh (Cambodia) had an incident. As the Airbus A321 aircraft was accelerating for takeoff, it suffered damage to the right engine, which in turn set the grass on fire next to the runway.

The FAA Emergency Airworthiness Directive (AD) was prompted by investigative findings.  An Airbus Model A321-231 airplane, powered by IAE V2533-A5 model turbofan engines, experienced an uncontained high-pressure turbine (HPT) 1st-stage disk failure that resulted in an aborted takeoff. This condition, if not addressed, could result in release of high-energy debris, damage to the engine, damage to the airplane, and loss of the airplane.
