**3.6 Collision between an Illushin IL-76 and a Boeing 747**

On November 12th, 1996, Kazakhstan Airlines Flight 1907, an Ilyushin Il-76 coming from Shymkent, Kazakhstan, was to land in Delhi [17]. In the meantime, Saudi Arabian Airlines Flight SV763, Boeing 747, had departed from Delhi for a passenger flight to Dhahran. Both aircraft collided, plummeted down in flames, and crashed in an arid farming area, resulting in 312 fatalities. The root and approximate cause of the collision was the unauthorized descending by the Kazak aircraft to FL140 and failure to maintain the assigned FL150. This is attributed to inadequate knowledge of English language of Kazak pilot, resulting in wrong interpretations of ATC instructions; poor airmanship and lack of proper CRM (Crew Resource Management) skill on the part of Pilot-in-Command, compounded by leadership quality lacking in him; casual attitude of the crew and lack of coordination in the performance of their respective duties by crew of Kazak aircraft; and absence of standard callouts from any crew member.
