On 24 September 2017, a Boeing 747-8UF, which had just made an easterly takeoff from Hong Kong on a moonless night but in good visibility, deviated from its correctly acknowledged SID clearance towards steep terrain and a resultant EGPWS PULL UP Warning was immediately actioned resulting in a terrain clearance of approximately 670 feet. The Investigation found that the SID track deviation was caused by the inadvertently incorrect input of a SID clearance which was supposed to be issued only to locally-based operators whereas the flight concerned was being operated by a foreign operator on behalf of a locally-based one.
