Accident account

The Antonov An-24RV operated by Angara Airlines was operating a passenger flight to Tynda, Russia, with 42 passengers and 6 crew members on board. On July 24, 2025, while the crew was conducting an approach to Tynda Airport, the aircraft struck a wooded area approximately 14 kilometers from the airport and was destroyed. All 48 occupants were killed.

The crew had discontinued an initial approach before making a second attempt to land. During the second approach, the aircraft descended below its assigned altitude, struck the treetops and then impacted the terrain. A fire broke out following the impact.

Weather conditions were poor, with visibility of 7,000 meters, light rain showers, scattered clouds at 210 meters and a broken cloud layer at 600 meters. The aircraft was approaching in instrument meteorological conditions (IMC). The accident resulted from a discrepancy between the altitude reference level based on the QNH pressure actually set on the barometric altimeters and the reference level used by the crew for assigned flight altitudes (based on QFE). This led to the aircraft flying approximately 600 meters below the assigned altitude, without the crew being aware of the deviation, colliding with treetops and the ground.

The accident resulted from a combination of the following factors:

  • The crew's lack of adequate preparation for operations at aerodromes that had transitioned to QNH-based procedures, resulting in errors in the use of aerodrome pressure settings (QNH/QFE) at Tynda Airport.
  • The air traffic controller's transmission of the QNH value, expressed in millimeters of mercury, without a prior request from the crew.
  • The crew's failure to verify the consistency between the barometric pressure settings in use and the assigned altitude values.
  • Air traffic control's inability to monitor the aircraft's altitude using radar equipment due to the unavailability of the secondary surveillance radar system at Tynda Airport.
  • The crew's deactivation of the aural alert of the Ground Proximity Warning System (GPWS).

The aircraft was registered RA-47315. It was completely destroyed in the accident.
