vilas is correct.
The documents entitled Modification Operational Impacts (MOI) are provided for information only.
MOIs are issued to inform operators, particularly operators'
flight operations and training departments, about the impact the referenced modification and/or Service Bulletin (SB) has on the operation of the aircraft as described in the flight operations documents mentioned in the MOI.
The MOIs particularly describe the impact a modification or a SB has on the FCOM.
Unless specifically listed in the MOI, other flight operations manuals may be affected without indication in the MOI.
MOIs provide a generic and non-customized technical description of the modification/SB, and briefly describe the associated operational impact.
Operators can use MOIs as support material to decide whether to apply the SBs to their fleet.
Operators can also use the MOIs as advance operational information in anticipation of an SB retrofit.
In all cases, the MOIs are to be used for information only, and the contractual flight operations manuals remain the support documentation of reference for flight crews.
