Thai aviation authorities are investigating an incident where a Singapore Airlines Airbus A330-300 was forced to divert to Bangkok after smoke was detected in the cargo hold.
The aircraft, registered as 9V-STO, was operating flight SQ446 between Singapore and Dhaka on April 22, but it diverted to Bangkok's Suvarnabhumi airport after the crew received an indication of smoke in the rear cargo hold.
"Extinguishing agents were discharged in the cargo hold and the aircraft landed uneventfully shortly after 20:00 Bangkok time," a spokesman for the airline says.
Passengers and crew were able to disembark safely from the aircraft using stairs and emergency services attended to the rear cargo hold, he adds.
SIA says that the aircraft will be flown back to Singapore once it has been cleared by the Thai authorities and checks have been carried out. The carrier is also conducting its own investigation into the incident.
Flightglobal's Ascend Online database shows that the A330 was delivered to SIA in June 2010 and is managed by DVB Bank Aviation Asset Management. It is powered by Rolls-Royce Trent 772 engines.
