FAA pauses engine fix because the problem is bigger than they thought

The US aviation regulator withdrew a proposed rule to fix specific engine parts on certain Rolls-Royce aircraft. This means the original fix was not enough, and the problem with the engine blades is more widespread than first realized.

The US aviation regulator had a plan to fix specific engine parts on certain planes. It turns out the problem affects more parts than they first realized. This means the original fix would not have made the planes safe enough, and a more extensive repair will eventually be required. For airlines operating these engines, this delays the immediate maintenance burden but signals a larger, more costly repair in the future.
