๐๐ฎ๐๐ฎ๐ธ๐ต๐๐๐ฎ๐ป ๐๐ถ๐ฟ๐น๐ถ๐ป๐ฒ๐ ๐๐น๐ถ๐ด๐ต๐ ๐ญ๐ต๐ฌ๐ณ was an international cargo flight from Shymkent to Delhi, operated by an Ilyushin Il-76 (Reg. UN-76435) on ๐ก๐ผ๐๐ฒ๐บ๐ฏ๐ฒ๐ฟ ๐ญ๐ฎ, ๐ญ๐ต๐ต๐ฒ.
While descending on Airway G452 the crew contacted Delhi: "Good evening 1907. Passing through 230 for 180, 74 miles from DPN". The controller then cleared the flight to descend to and report at FL150. In the meantime, ๐ฆ๐ฎ๐๐ฑ๐ถ ๐๐ฟ๐ฎ๐ฏ๐ถ๐ฎ๐ป ๐๐ถ๐ฟ๐น๐ถ๐ป๐ฒ๐ ๐๐น๐ถ๐ด๐ต๐ ๐ณ๐ฒ๐ฏ, a Boeing 747 (Reg. HZ-AIH), had departed Delhi at 18:32 for a passenger flight to Dhahran. The Delhi controller cleared the flight to climb to FL140. Because Flight 1907 was approaching from the opposite side, the controller told SV763: "Maintain level 140, Standby for higher."
A little later, Flight 1907 reported reaching FL150. The controller then responded: "Roger. Maintain 150. Identified traffic 12 o'clock, reciprocal Saudia Boeing 747, 14 miles. Report in sight." The Kazakh crew replied by querying the distance to which the controller answered: "14 miles now, roger 1907." The Kazakh plane then descended below its assigned altitude and was flying at 14,190 feet. Shortly afterwards both planes collided and crashed an arid farming area.
๐ฃ๐ฟ๐ผ๐ฏ๐ฎ๐ฏ๐น๐ฒ ๐๐ฎ๐๐๐ฒ:
The root and approximate cause of the collision was the unauthorised descending by the Kazak aircraft to FL-140 and failure to maintain the assigned FL-150.
The factors contributing to the unauthorised descent of Kazak aircraft to FL-140, departing from the assigned FL-150, were:
i) inadequate knowledge of English language of Kazak pilot, resulting in wrong interpretations of ATC instructions.
ii) poor airmanship and lack of proper CRM (Crew Resource Management) skill on the part of PIC (Pilot-in-Command) compounded by leadership quality lacking in him.
iii) Casual attitude of the crew and lack of coordination in the performance of their respective duties by crew of Kazak aircraft.
iv) Absence of standard callouts from any crew member.
