On Nov 15th 2025 the FAA superseeded EAD 2025-23-51 with the new
Emergency Airworthiness Directive 2025-23-53 including MD-11, MD-11F, MD-10-10F, MD-10-30F, DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, and DC-10-40F aircraft. The FAA reasoned:
Since the FAA issued emergency AD 2025-23-51, it has been determined that additional airplane models are subject to the same unsafe condition. The engine-pylon structure of the Model MD-11 and MD-11F airplanes is similar in design to that of the Model MD-10-10F, MD-10-30F, DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, and DC-10-40F airplanes. The FAA, therefore, is superseding emergency AD 2025-23-51 to add these additional airplane models to the applicability of this emergency AD.
