Cathay Pacific said on Saturday that maintenance on its operational fleet of Airbus A350 jets has been completed, and all aircraft requiring engine component replacement have been repaired successfully and cleared for operation.

Hong Kong's flag carrier said earlier that 15 aircraft needed components replaced, after their engineering team inspected its fleet of A350s.

The company had cancelled dozens of flights since an engine glitch forced the return of a plane bound for Zurich on Monday.

The airline had said earlier that the engine component failure identified in its planes is the first of its kind on any A350 aircraft in the world.
