A Cathay Dragon Airbus A321-200, registration B-HTD performing flight KA-896 from Hong Kong to Shanghai Pudong (China), was climbing through FL080 out of Hong Kong's runway 07R when the crew received indication that all ADIRUs (#1, #2, #3) disagreed with each other. The crew continued the climb stopping the climb at 7000 meters. The position data transmitted by the aircraft's transmitter suggested the aircraft was about 145nm southeast of Hong Kong at FL231 heading towards Laoag (Philippines) when the aircraft turned around to return to Hong Kong with both Flight Management Guidance Computers having failed. The aircraft returned to Hong Kong for a safe landing on runway 07R about one hour after departure.

A replacement A321-200 registration B-HTJ reached Shanghai with a delay of 3.5 hours.
