GM1 ML.A.302(c)(3) Aircraft maintenance programme ED Decision 2023/013/R ALTERNATIVE MAINTENANCE ACTIONS ‘Maintenance actions alternative to those referred to in point (c)(2)(b)’ refer to when the ICA issued by the DAH or the declarant of a declaration of design compliance are used as the basis for the AMP development and the CAMO, CAO or owner (as applicable), when developing the AMP, decides to deviate from certain of these instructions issued by the DAH or the declarant of a declaration of design compliance, introducing, for example, a less frequent interval than or a different task type (inspection instead of check) from the one established by the ICA. These alternative maintenance actions shall not be less restrictive than those set out in the applicable MIP. This means that the extent of the maintenance to be covered by the deviating task cannot be less than the extent of the corresponding task in the MIP in terms of frequency and task type.
