On 21 September 1995, the Antonov An-24 aircraft crashed during its final approach to Mörön Airport, resulting in the death of 41 out of the 42 individuals on board.

Aircraft

The aircraft involved was an Antonov An-24RV, bearing serial number 57310103 and construction number 101-03. It was produced in 1975 by the Antonov Serial Production Plant and was delivered to MIAT Mongolian Airlines during the period of the Mongolian People's Republic. The plane was registered as BNMAU-10103 at the time of the accident. Although the registration МТ-1008 had been designated for this aircraft, it had not been assigned before the crash occurred.

Accident

Flight 557 carried a total of 37 passengers alongside six crew members from Ulaanbaatar to Mörön. During the flight, the pilots opted to continue under visual flight rules, judging weather conditions to be sufficient for this mode. However, on their descent toward the destination, they began lowering altitude too early. At approximately 12:30 local time, the aircraft impacted Choho Geologloh Uul mountain. This collision resulted in fatalities among all six crew and 36 passengers. The sole survivor was a passenger named Ulziibayar Sanjaa.
