==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 [[Course (navigation)#Aircraft heading|heading]] of 199 degrees instead of 140. ATC subsequently gave the proper heading, but instructed the crew to descend to {{convert|600|m|ft|abbr=on}}, whereas the minimum safe altitude for the surrounding terrain was {{convert|4620|m|ft|abbr=on}}.<ref name="airdis"/> 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 [[Flight Regulations of the Civil Aviation of the USSR|Soviet flight regulations]], the crew chose to make a turn instead, continuing their descent to {{convert|600|m|ft|abbr=on}}.<ref name="airdis"/> Having informed ATC of their situation, the crew received a [[Ground proximity warning system|ground proximity warning]]. Instead of making an urgent [[climb (aeronautics)|climb]], the crew delayed any attempt to climb until 1–2 seconds before impact.<ref name="airdis"/>

The aircraft crashed into Dolan Mountain, at an altitude of {{convert|690|m|ft|abbr=on}}, {{convert|30|km|mi nmi|abbr=on}} from [[Almaty airport]], disintegrating and catching fire.<ref>{{cite web | url =http://www.megapolis.kz/art/I_nikogo_ne_zashchitila_vdali_obeshchannaya_vstrecha_-2012_05_13| script-title=ru:И никого не защитила вдали обещанная встреча…|publisher =Megapolis.kz|language=Russian|date=14 May 2012| accessdate = 5 December 2013}}</ref> At the time of the accident there was [[cumulo-nimbus]] cloud cover at an altitude of {{convert|3000|-|4500|m|ft|abbr=on}}  with [[cloud top]]s of {{convert|7000|-|8000|m|ft|abbr=on}} and a visibility of {{convert|10|km|mi nmi|abbr=on}}.<ref name="airdis"/>

==Investigation==
The crash of Flight 5463 was attributed to the following causes:<ref name="Gero">{{cite book |title=Aviation Disasters Second Edition |last1=Gero |first1=David |publisher=Patrick Stephens Limited |year= 1996 |pages=176–177 }}</ref>-

*Violation of the approved approach scheme to [[Alma-Ata airport]]
