Silk Way West Airlines flight 7L625, a Boeing 777-F (VP-BMU), and MNG Airlines flight MB380, an Airbus A330-343 (P2F) (TC-MCN) were involved in a loss of separation event during departure from Hong Kong Airport (HKG).
Both flights were cleared by ATC to depart from Runway 07C and Runway 07R respectively, following standard flight procedures. After taking off, both cargo flights were subsequently instructed by ATC officers to climb to 5 000 feet and 3 000 feet, respectively, to maintain vertical separation. However, as the climbing rates of the two cargo flights varied from what the ATC officers had anticipated, the desired vertical separation was not achieved. During this time, both cargo flights followed standard departure procedures and maintained visual contact with each other. When the aircraft were approximately 7 nautical miles northeast of HKIA, the traffic collision avoidance system of the Silk Road Western Airlines' B777 cargo flight issued an alert to its crew, and the aircraft then descended to 2 500 feet. After the incident, both aircraft continued to their destinations according to their flight plans.
Based on preliminary data on hand, the closest spacing between the two aircraft was approximately 0.4 NM (750 m) horizontally and 100 ft vertically, with the aircraft on converging headings.
