(TMI) – Safety fears have cropped up again in klia2 as taxiways and aircraft parking bays are slowly sinking due to torrential rain and impact from the hundreds of aircraft landings and take-offs at the new budget airport terminal.

They also said there were reports of some AirAsia Airbus 320 passenger aircraft moving on the bumpy parking bays despite having safety-chocks to block the wheels from turning. AirAsia is the airport terminal’s biggest customer.

“What happened was when brakes were released on the main wheel, the aircraft moved back due to the slope/depression. In this case, the momentum was just enough to cause it to climb and stop on the chock. The aircraft chocks that we used are as per Airbus specs.

“This has been happening every day and we have asked our guys not to be anywhere behind the aircraft when we release the brakes. It’s becoming very dangerous,” a source told The Malaysian Insider.

It is learnt that AirAsia is working with airport operator Malaysia Airports Holdings Bhd (MAHB) to resolve the matter although the airport had passed checks by the International Civil Aviation Organisation (ICAO) weeks before it opened for business.

It is understood that MAHB workers have been busy resurfacing the tarmac at the klia2 terminal after AirAsia officials complained of the soft ground conditions, and are using densiphalt – a composite paving material of asphalt and concrete, rather than just asphalt that is normally used for such areas.

“We have felt a very hard impact to the aircraft when taxiing at speed around 15 knots.

“Three of them are at zone wing P before the sky bridge when taxiing towards runway 33. As I remember it’s abeam bay P3 & P5. The other 2 around bay Q7. Will update further if manage to taxi on U4 again,” the pilot said in the report sighted by The Malaysian Insider.

The pilot also told his airline that he had been avoiding taxiway U4 since May 11 by “requesting other taxi routing from ground if traffic permits for pax comfort”.
