Owner/operator: Katekavia

Registration Number: RA-46524

Location: 0,4 km W of Igarka Airport (IAA) – ÿ Russia

Phase of Flight: Approach

Status: Destroyed, written off

Casualties: Fatalities: 12 / Occupants: 15

Component Affected: Aircraft (specifically the approach phase and the flight path)Aircraft (specifically the approach phase and the flight path)

Investigating Agency: MAKMAK

Category: Accident

On August 2, 2023, an Antonov 24 passenger plane crashed while on final approach to Igarka Airport (IAA) in Russia. The flight, carrying four crew members and eleven passengers, was cleared for an approach to runway 12. Initial reports indicate a significant incident involving a catastrophic crash, resulting in the deaths of all passengers and one crew member. The aircraft drifted to the right, striking trees at a distance of 477 meters short of the runway and 234 meters to the right of the extended centerline. A fire erupted, destroying the aircraft. The cause of the crash was determined to be a failure to execute a timely and correct approach due to conditions exceeding the airfield and pilot’s minimum safe height. The aircraft descended below 100 meters, lacking reliable visual contact with approach lights and runway lights, leading to a collision with trees and the ground. The incident was attributed to meteorological shortcomings, specifically an incorrect weather forecast regarding cloud cover, visibility, and severe weather, coupled with inaccurate information regarding the actual weather path at the Middle Marker. The investigation into the Tu-134A incident at Kurumoch airport highlighted the importance of improved meteorological support operations.On August 2, 2023, an Antonov 24 passenger plane crashed while on final approach to Igarka Airport (IAA) in Russia.

Description

An Antonov 24 passenger plane crashed while on final approach to Igarka Airport (IAA). Flight KTK-57 had originated at Krasnoyarsk-Cheremshanka Airport (UNKM) for the three hour and ten minutes flight to Igarka. There were four crew members and eleven passengers on board. The actual load was 3,412 kg, including 10 adult passengers, 1 child, 206 kg of baggage and 2426 kg of cargo (among which 900 kg of food and 1,366 kg of building materials). The cargo was located on the first 4 rows of passenger seats. Flight 57 departed at 21:41 local time, August 2. The flight towards Igarka was uneventful. Visibility at Igarka was limited due to fog. The flight was cleared for an approach to runway 12. The crew continued the approach below 100 m even though they had not established positive visual contact with the runway. The airplane drifted to the right until it struck trees at a distance of 477 m short of the runway and 234 meters to the right of extended centreline. It came to rest after sliding 140 m through trees. A fire broke out, destroying the aircraft. All eleven passengers and one crew member were killed in the accident. Rosaviatsia reported the weather at the time of the approach to be: clouds at 220 meters, visibility 3.5 km02:00, rain, wind 150 ø 3 m / sec. CONCLUSION: (translation from Russian original) The cause of the crash of AN-24RV RA-46524 was the execution of an approach in conditions worse than the weather minima of the airfield, aircraft, and pilot. The failure of the crew to take a timely decision for a missed approach when the plane descended below the minimum safe height (100m) in the absence of reliable visual contact with approach lights and runway lights. This caused the aircraft to strike trees and the ground in controlled flight. Factors contributing to shortcomings in the meteorological services of this flight were: – Incorrect weather forecast with regards to cloud ceiling, visibility and severe weather – fog. – Inaccurate information about the actual weather on the glide path at the Middle Marker with course 117ø, radioed to the crew 40 minutes before the accident. The timely implementation of recommendations to improve meteorological support operations developed by the Commission to investigate the crash of Tu-134A RA-65021, which occurred at the airport Kurumoch, Samara March 17, 2007, could have prevented the crash of AN-24RV RA-46524.

Primary Cause

Failure to execute a timely and correct approach due to conditions exceeding the minimum safe height, resulting in a collision with trees and ground.Failure to execute a timely and correct approach due to conditions exceeding the minimum safe height, resulting in a collision with trees and ground.
