A Hong Kong Airlines Airbus A330-200, registration B-LHA performing flight HX-707 from Hong Kong (China) to Denpasar (Indonesia) with 280 people on board, was climbing out of Hong Kong's runway 25L when the crew stopped the climb at 6000 feet reporting a hydraulic leak. The aircraft continued the climb to FL090 while positioning for the return to runway 25L. Upon touchdown on runway 25L loud bangs were heard associated with a large cloud of white smoke, the aircraft rolled out without further incident and became disabled on the runway with two tyres blown. The passengers disembarked onto the runway and were bussed to the terminal.
The runway was closed for about 105 minutes until the aircraft was towed off the runway.
The airline reported the aircraft experienced a technical problem prompting the return.
A replacement A330-200 registration B-LNI reached Denpasar with a delay of about 5 hours.
On Oct 16th 2019 Hong Kong's AAIA reported ECAM messages about green and blue hydraulic system pressures being low appeared prompting the crew to declare Mayday and return to Hong Kong. During landing on Hong Kong's runway 25L tyre #5 burst disabling the aircraft on the runway for about 100 minutes until the wheel assembly was replaced. The occurrence was rated a serious incident and is being investigated by Hong Kong's AAIA.
On Jun 15th 2020 the AAIA released their preliminary report and wrote:
On 29 September 2019 at about 1223 hrs, a Hong Kong Airlines Limited Airbus A330-243 aircraft, flight HX707 took off from Runway 25L at the Hong Kong International Airport (VHHH). Upon reaching 1500 ft on climb out at about 1225 hrs, the Electronic Centralized Aircraft Monitoring (ECAM) warnings and the associated messages indicated that the pressures in the Green and Blue hydraulic systems were low.
The flight crew carried out the emergency procedures accordingly, subsequently declared MAYDAY and decided to return to VHHH for a full emergency landing.
The aircraft landed and stopped safely on Runway 25L with the No. 5 tyre burst. The runway was subsequently closed for about an hour and forty-five minutes.
The inspection of the left landing gear wheel well revealed that a manual valve had detached from the Green hydraulic system Ground-Service Manifold and a Blue hydraulic system return pipe was punctured.
