also.. if a LAME has endorsed the maintenance release with 'Oil cx + filter insp IAW Lyc SB 480E' at '7339 (or F/SW 1889) or each 4 mths'. it will have to be carried out regardless of AD/ENG/4 and as that SB does include filter screen inspection and filter disassembly / inspection which a pilot cannot carry out under Schedule 8. For example if the engine had made metal previously or any other maintenance concern this could be added as an extra requirement to the AD.
Discussing this with the maintenance organisation and the LAME that issued the MR is the best advice.
