Singapore Airlines (SIA) said on Thursday it found burn marks on electrical wiring in an Airbus A380 superjumbo after smoke entered a lavatory during a flight earlier this week.
The flight crew activated an extinguisher after smelling smoke coming from one of the aircraft’s toilets while the plane was approaching Changi Airport from Hong Kong, said S. Supramaniam, an airline spokesman.
“When the plane landed, our ground crew inspected the aircraft and they discovered some burn marks on some electrical wirings underneath the lavatory, on the cargo hold,” he said.
“Airbus and SIA are investigating the matter. We have also inspected all the other A380s and nothing was found.”
Supramaniam said there was no fire and the plane landed safely without incident.
SIA became the first airline in the world to commercially fly the double-decker A380 in October 2007. It has 11 A380s in its fleet.
In November last year, an explosion ripped through one engine of an A380 operated by Qantas shortly after takeoff from Singapore with 466 people aboard, forcing it to turn back and make an emergency landing.
