Aeroflot Flight 5463 was a Soviet domestic passenger flight from Chelyabinsk to Almaty which crashed on 30 August 1983 while approaching Almaty. The Tupolev Tu-134A collided with the western slope of Dolan Mountain at an altitude of 690 m (2,260 ft). As a result of the accident, all ninety people on board were killed. Crew error was cited as the cause of the accident.[1]
Accident[]
Having received the information about the aircraft's location, air traffic control (ATC) gave an erroneous instruction to turn. The crew also mistakenly chose a heading of 199 degrees instead of 140. ATC subsequently gave the proper heading, but instructed the crew to descend to 600 m (2,000 ft), whereas the minimum safe altitude for the surrounding terrain was 4,620 m (15,160 ft).[1] Knowing that the aircraft was on collision course with mountainous terrain and having the right to ignore the ATC in this situation, according to the , the crew chose to make a turn instead, continuing their descent to 600 m (2,000 ft).[1] Having informed ATC of their situation, the crew received a ground proximity warning. Instead of making an urgent climb, the crew delayed any attempt to climb until 1–2 seconds before impact.[1]
The aircraft crashed into Dolan Mountain, at an altitude of 690 m (2,260 ft), 30 km (19 mi; 16 nmi) from Almaty airport, disintegrating and catching fire.[2] At the time of the accident there was cumulo-nimbus cloud cover at an altitude of 3,000–4,500 m (9,800–14,800 ft) with cloud tops of 7,000–8,000 m (23,000–26,000 ft) and a visibility of 10 km (6.2 mi; 5.4 nmi).[1]
Investigation[]
The crash of Flight 5463 was attributed to the following causes:[3]-
- Violation of the approved approach scheme to Alma-Ata airport
- Failure of the executive flight manager to monitor the situation
- Violation of the flight operations manual by the crew for following the instructions of the final controller to descend below a safe altitude.
