🇬🇧 English

The rule updates mandatory safety checks for certain Rolls-Royce Trent 1000 aircraft engines. Operators must inspect high-pressure turbine blades for axial cracks, repeat those inspections at required intervals, and replace blades or carry out extra checks when inspection results show a problem. The change affects airlines, aircraft operators, maintenance providers, and parts planners using the covered Trent 1000 engine models. It also allows an optional terminating action that can end the repeated blade inspections if the specified upgraded parts or configuration are installed.
