@A33Zab
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.
Thank you A33Zab, that is very helpful and new to me.
Presumably, since the MOI is advanced operational information there will be an official accompanying SB and an FCOM change if and when the modification is fitted? Does anyone know of such a change so we can study it in more detail?
