In which cases can component maintenance with rating A be performed?

Under Rating A, simple maintenance of components installed in the aircraft can be done according to the CMM, which can even be disassembled for better access, as long as they do not involve extra maintenance of the aircraft. These tasks are released by the CRS of the aircraft where the component was installed.

Therefore, according to the standard, it is not possible to keep a component under rating A outside the aircraft to be installed on another aircraft, since the standard states that the component must be installed on that aircraft and its maintenance released with the CRS of the aircraft. If the organisation wants to do so, it should ask for the scope of components, even for simple tasks.
