KLIA2 could be engulfed in flames with drop of a cigarette butt, a DAP lawmaker warned.

Petaling Jaya Utara MP Tony Pua said this is because there is a fuel leak caused by damaged pipes at the airport's apron.

The pipes were damaged due to the same sinking soil that causes flooding on the tarmac, he claimed.

"It is creating a massive safety hazard.

"Simple things like a cigarette butt being thrown down could light up the whole airport," he warned.

Yesterday, two bays at the KLIA2 in Sepang were closed due to fuel spillage .

However, Malaysia Airports Holdings Bhd said the cause of the spillage was unknown.

Pua called on the Transport Ministry to take the necessary steps to remedy the situation.

He also questioned why the ministry had not taken action against the MAHB officers whom the Public Accounts Committee had recommended that action be taken for bungling the construction of KLIA2.

MAHB has spent RM76.5 million to repair defects at the budget airline airport since it began operations in May 2014.

Transport Minister Liow Tiong Lai said the independent audit committee, which was set up in January to investigation safety issues surrounding KLIA2, would table its final audit report by end of this month.

The problems included flood waters in the runway and cracks at the terminal building.

Another special task force, which audits the airport's construction and development, will need six months to draft its detailed report.

DCA briefed on incident

Meanwhile, Bernama reports that in a statement issued today, MAHB said the fuel leaks at Bay Q10 and Q12 of the KL International Airport 2 (KLIA 2) in Sepang are not due to soil depression as reported in the media.

It said according to Kuala Lumpur Aviation Fueling Systems (KAFS) which is responsible for management, operations and maintenance of the pipelines, the pipelines are resting on pile-to-set foundation and hence they are not affected by soil settlement.

"As reported earlier, only two bays - Q10 and Q12 are affected by this incident and KAFS is currently carrying out inspection to identify the root cause. The Department of Civil Aviation has also been briefed on this incident," it said.

The statement also said the airport operations at KLIA 2 are not affected as the are sufficient bays to cater for wide body aircraft daily operations.

"Based on flight operations data, there are nine (9) other contact bays and six (6) remote bays available for wide body aircraft requirements.

"Malaysia Aiports will be engaging closely with the airlines in order to brief them and provide reassurance that the flight operations will not be affected," it said.
