Singapore Airlines (SQ, Singapore Changi) has confirmed it has grounded two of its nine B787-10s following issues with their respective Rolls-Royce 1000 TEN powerplants.

In a statement, the carrier said recent precautionary checks, conducted in tandem with Rolls-Royce, had uncovered signs of premature blade deterioration on select engines. As such, two Singapore Airlines B787-10s have been removed from service pending engine replacements.

"Singapore Airlines is working closely with Rolls-Royce and the relevant authorities for any additional follow-up actions and precautionary measures that may be required going forward," it added.

Singapore Airlines said that in light of the drop in B787-10 fleet numbers, it has been forced to use other aircraft to operate their flights in order to minimise schedule disruption to passengers. However, as capacity may be lower on replacement aircraft, some passengers have been rebooked onto other flights.

For its part, Scoot (TR, Singapore Changi) currently operates ten B787-8s and eight B787-9s. At least one of its -9s has also undergone scrutiny.

Rolls-Royce has yet to issue a public comment.
