Skidded Malaysia Airlines aircraft in Sibu well handled


KUALA LUMPUR: Passengers onboard Malaysia Airlines Flight MH2718 which skidded on landing at the Sibu Airport last Saturday were safe as the aircraft captain handled the situation well, said aviation experts.

They concurred that the pilot succeeded in steering the Boeing 737-800 jetliner carrying 61 passengers and six crew members, by reducing the risk of accident despite facing bad weather.

Prof Dr Mohd Harridon Mohamed Suffian believed the captain had made precise technical calculatio­ns before making the decision to land the aircraft.

“The decision should be made based on mathematic­al calculatio­ns taking into considerat­ion the length of the runway and the coefficien­t of friction between the wet runway and aircraft tyres. Data on the length of the runway is available in the data sheet at the aircraft cockpit. For me, I would also consider the brake force needed to stop the plane on a wet runway,” he told Bernama yesterday.

“If the calculatio­ns show the aircraft does not have the full capability to stop within the runway range, I will attempt to land in another airport,” added the Universiti Kuala Lumpur (UniKL) test pilot.

It was reported MH2718 from Kuala Lumpur skidded while landing in Sibu Airport during heavy rain Saturday night and there was no casualty. All passengers safely disembarke­d via two evacuation slides and investigat­ions were conducted to determine the cause of incident.

Several passenger claimed the runaway was clogged and they heard the sound of brakes being applied before the aircraft skidded and stopped. Passengers said the pilot had acted profession­ally in such adverse circumstan­ces for everyone’s safety.

Mohd Harridon said when an aircraft skidded, the standard operating procedure was to activate the evacuation slides after coming to a halt. He said the flight crew should also count and ensure all passengers disembarke­d from the plane and the pilot should ensure all engines were switched off to reduce the risk of fire.

Sharing the view was Captain Abdul Rahmat Omar Tun Mohd Haniff who described the move to land the aircraft as a good decision as compared to other choices such as circulatin­g longer in the air.

“When an aircraft skids, the pilot has to use the foot brake alternativ­ely to reduce skids with speedbrake­s on the wings while applying brakes on the tyres and using the thrust reverser to slow down the plane.

“Circulatin­g in the air to wait for better weather is another alternativ­e but it will burn more fuel. The other choice is to land at another airport where the weather is fine,” said the former Royal Malaysian Air Force (RMAF) investigat­ing officer.

Asked on the measures to be taken in another similar situation, Abdul Rahmat said if the rain was extremely heavy, the airport management should get personnel to check the runway surface and advise the air traffic control and airlines concerned on whether to land or proceed to another airport. Another aviation expert-cum-local pilot who declined to be identified said if an aircraft skidded off the runway, it was usually due to the runway contaminat­ed by rain or snow.

“The right thing to do is to evacuate the aircraft as quickly as possible and get the passengers somewhere safe, which was most probably what they did,” he said.
