The Airbus A330 plane "encountered heavy rain and veered slightly off the runway on landing" yesterday, scheduled for 9:20 am (local time), before it was steered safely back, the airline said in a statement.
"The aircraft was towed to the gate and customers disembarked normally," the airline said in a statement, adding that a replacement plane was sent to Yangon for the return flight.
The plane, flight SQ998 on a daily route to Myanmar, was carrying 265 passengers and crew, the airline told AFP.
On May 9, an Airbus A380 superjumbo operated by the airline on a flight to Hong Kong was forced to turn back to Singapore after pilots received a warning about a problem with a cargo door.
In January, one of the airline's A380 fleet was forced to make an emergency landing in Azerbaijan after suffering a drop in cabin pressure.
The flag-carrier subsequently said its investigation into the incident focused on a main deck door that appeared to have suffered a leak.
Singapore Airlines has 19 A380s with five others on order, operating on routes from Singapore to various destinations including Hong Kong, Frankfurt, London and Los Angeles.
