Cathay Pacific flight CX86, operated by Atlas Air, overflew mountainous terrain below the Minimum Sector Altitude shortly after takeoff from Hong Kong-Chek Lap Kok International Airport.
The Boeing 747-87UF cargo plane took off from runway 07R at 23:43 LT (15:43 UTC). It was cleared for the OCEAN 2A Standard Instrument Departure (SID). This calls for a heading of 073 after takeoff, heading towards the PORPA waypoint. After PORPA the aircraft would have to turn right, after passing the mountainous area on Lantau Island.
However, the flight did not follow the SID and turned right soon after takeoff, overflying Lantau Island. The aircraft crossed a 1443 feet high mountain. ADS-B data of the flight show a recorded altitude of between 2050 and 2475 feet amsl as the aircraft overflew the mountain.
The Minimum Sector Altitude there was 3000 feet
