SINGAPORE - A Scoot aircraft returned to Changi Airport about an hour after it departed for Sydney, Australia, after an indicator light in the cockpit went off. The plane had taken off from Singapore at 1.45am on Wednesday.

"As a precaution, the flight crew made the decision to bring the aircraft back to Singapore to have the indicator checked out" a spokesman for the budget carrier said.

All the passengers of flight TZ2 were transferred to another aircraft which took off at 9.43am on Wednesday. All other scheduled flights remain unaffected, he said.

The affected aircraft was checked out by engineers and the indicator light was found to be benign, he added.

Scoot is wholly owned by Singapore Airlines.
