An Antonov Design Bureau Antonov AN-124-100, registration UR-82072 performing flight ADB-5250 from Ostend (Belgium) to Mazar-i-Sharif (Afghanistan), was accelerating for takeoff from Ostend's runway 26 at about 19:05L (18:05Z) when the crew rejected takeoff at high speed (about 110 knots over ground) due to a poblem with the #2 engine (D-18T, inboard left hand). The aircraft slowed safely and returned to the apron.

On Nov 29th 2019 Antonov Design Bureau told The Aviation Herald: "Because of the surge of the second engine of the AN124-100-150, the decision to the take off was aborted. The aircraft was inspected by Antonov technical specialists and no damage was found. The engine has been sent to the manufacturer for further investigation, and in order to ensure that our obligations to the customer are fulfilled, another aircraft was sent to Ostend."

Ukraine's NBAAI reported in their November 2019 Bulletin that the #2 engine failed at about 110 KIAS during the takeoff run from runway 26. The aircraft slowed safely and returned to the apron. Debris was collected from the runway. Belgium's AIB is investigating the occurrence.

On Mar 11th 2020 the State Aviation Administration of Ukraine released their Airworthiness Directive AD-0890-20 stating that an uncontained engine failure had occurred. The source of the failure had been the destruction of the 2nd stage disk rim of the intermediate pressure compressor. The AD requires:

Within a period of 6 months or until an engine time in service will be 250+50 hours (whichever comes first) after effective date of this AD, conduct one-time eddy current inspection of the 2nd stage disk dovetails of the intermediate pressure compressor in accordance with the instructions of the "Service Bulletin for Inspection No. ISB 18T-72.30-137" of SE "Ivchenko-Progress".

The results of AD implementation shall be sent to the engine manufacturer JSC MOTOR SICH and the TC holder SE Ivchenko-Progress within 3 working days.

In case if any cracks are detected in the area of 2nd stage disk ovetails of the intermediate pressure compressor the engine shall be removed from aircraft and corrective actions in accordance with the instructions of SE Ivchenko-Progress shall be performed.
