Two Singapore Airlines Boeing 787 grounded due to Rolls-Royce engine issue

Singapore Airlines found “premature blade deterioration” during routine inspections of some plane engines, leading the carrier to ground two Boeing Co. 787-10 aircraft in a widening turbine problem for Rolls-Royce.

The carrier, in consultation with the engine-maker, identified other Trent 1000 TEN engines in its 787 fleet to undergo precautionary inspections, Singapore Airlines said in a statement Tuesday.

All these inspections have been concluded, and a remaining check will be completed on a 787-9 aircraft of its Scoot budget carrier by Wednesday.

The new fan issue exacerbates a problem that has beset the Rolls-Royce engine, one of two turbine choices on the 787, since at least 2016. Blade wear has prompted previous groundings of the wide-body planes – Boeing’s most advanced model – for early repairs. It comes at an inopportune time for Boeing, which faces a global grounding of its best-selling 737 Max after two crashes raised safety concerns with regulators.

Rolls-Royce said in a statement it will work with affected customers to accelerate an implementation of enhanced replacement blades and “to ensure that we can deliver on our Trent 1000 TEN future commitments.”
