Rolls-Royce jet engine inspections get a new ultrasound method

US aviation regulators are updating rules for inspecting certain Rolls-Royce jet engines. The new rules allow for a more advanced ultrasonic inspection method to detect cracks in fan disks. This means airlines can use a better tool to check engine safety, potentially reducing the need for visual inspections.

Airlines that operate jets with these specific Rolls-Royce engines now have a more reliable way to check for dangerous cracks. The old method relied on visual inspections, which can miss small flaws. This change means a better chance of catching problems before they cause an engine failure, improving flight safety.
