FAA ordered carriers who operate IAE-powered A320-family airframes to perform urgent maintenance on the aircraft.
This order came after a Vietnam Airlines A321-231 had an engine exploded last week while taking off:

Upon examination of the affected aircraft, authorities discovered that the Airbus 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”.
The FAA’s ruling was that 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.” Involving International Aero Engines V2500 powerplants, the emergency airworthiness directive (AD) has been issued to prevent further failures of high-pressure turbines.
