A Singapore Airlines Airbus A380-800, registration 9V-SKB performing flight SQ-322 (scheduled dep Apr 18th, actual dep Apr 19th) from Singapore (Singapore) to London Heathrow,EN (UK), departed with delay following maintenance works on two engines (Trent 970) at the gate and was climbing out of Singapore when the crew stopped the climb at 10,000 feet and decided to return to Singapore due to the failure of two engine bleed air systems and resulting air conditioning problems. The aircraft landed overweight about 30 minutes after departure and rolled out without further incident, 8 main gear tyres deflated as result of the landing.

A replacement Airbus A380-800 registration 9V-SKE reached London with a delay of 11.5 hours.

The airline reported a number of tyres deflated during landing when the aircraft returned to Singapore due to air conditioning problems.

Passengers reported they had been pushed back and engine start commenced, however two engines did not light up. Maintenance worked on those engines for two hours, then the aircraft departed, however, the air conditioning did not work. The aircraft returned to Singapore and touched down "so hard", a number of tyres burst.

The Aviation Herald learned that engines #3 and #4 (both right hand engines) were suffering from low starter pressure and could thus not be started. The problem was solved after about 2 hours and the aircraft departed. Climbing through 4000 feet the crew received indications that air conditioning systems #1 and #2 had failed, the crew worked the related checklists but were unable to reset the packs. The aircraft performed an overweight landing at 523 tons, the brakes reached temperatures of up to 820 degrees C which resulted in 8 tyres deflating while the aircraft turned off the runway. The passengers disembarked via mobile stairs onto the taxiway.
