Rolls-Royce jet engine inspections can now use a better ultrasound method

The US aviation regulator has updated its rules for inspecting certain Rolls-Royce jet engines. Airlines can now use an improved ultrasonic inspection method instead of just visual checks for cracks in a critical engine part.

Airlines previously had to rely on visual inspections for cracks in a specific part of these jet engines, which is less reliable. The new rule means they can use a more advanced ultrasound technique. This should make it easier to find potential problems before they become serious, improving safety and potentially reducing maintenance downtime.
