A Sydney-bound Scoot flight returned to Changi Airport yesterday after being in the air for about an hour.
A spokesman for the low-cost airline told The New Paper: "Flight TZ2 to Sydney turned back when an indicator light appeared in the cockpit."
One of the passengers, Mr Shannon Tan, said that the flight turned back at about 2.45am.
Scoot said: "As a precaution, the flight crew made the decision to bring the aircraft back to Singapore to have the indicator checked out."
The airline added that the affected aircraft was swopped with a new one.
"All passengers were transferred to the new aircraft and a new set of crew was deployed to operate the flight," the Scoot spokesman said.
Scoot, which is wholly owned by Singapore Airlines, added: "The affected aircraft was checked out by engineers and the indicator light was found to be benign."
When asked what the indicator light was for, it declined comment.
The flight took off again at 9.43am.
While he was at Changi Airport, Mr Tan texted a friend to say that passengers of the affected plane had to board a bus at the airport after the plane turned back.
"The bus was supposed to take the passengers to the new aircraft. However, while the crew were preparing the plane, we were left waiting in front of the bus," said Mr Tan in the message, which the friend forwarded to The New Paper.
Mr Tan was not contactable after the second flight took off. The return flight from Sydney to Singapore was also delayed as a result of the aircraft swop.
