200 sections · 1,360 audit questions · Implementing Rule, AMC and GM · v2025-09-02
Part-145 sits at the operational end of the maintenance chain — every shall and should in the Implementing Rule maps to a procedure the AMO has to evidence in practice, not just declare in the MOE.
Authoring this Part surfaced ~30 paragraphs where the AMC narrows the IR enough that the audit question has to change shape — particularly in the personnel and certifying-staff subparts, where the IR sets the obligation and the AMC sets the actual standard. Those shifts are reflected in the checklist’s See-also fields and in the way the Compliance Matrix groups its rows.
