Part A - Maintained Use, Policy, Failure, and Condition

§ID & TitleStatusKeywords & Search QueriesDependencies
1MNT.1 - Identify the Maintained System, Use, and Permission BoundaryStableKeywords: equipment identity, required function, configuration, control. Query: “Which System and use does this maintenance question concern?” Bound the question and its operating and permission conditions.FPF A.1.SCR, A.2.8.PER; SYSE.13
2MNT.2 - Select and Reopen the Maintenance PolicyStableKeywords: maintenance policy, corrective, preventive, condition-based, failure-finding. Query: “Which task should be retained or changed for this failure?” Compare applicable tasks and response conditions without a technology ladder.MNT.3, MNT.4, MNT.5; FPF C.11.DUA
3MNT.3 - Establish Degradation and Failure Evidence for MaintenanceStableKeywords: failure evidence, mechanism, cause, exposure, censoring. Query: “What does the failure history actually support?” Separate observation, diagnosis and consequence at the resolution needed by the decision.MNT.1, MNT.4, MNT.12; FPF A.10, C.16
4MNT.4 - Monitor and Interpret System Condition for MaintenanceStableKeywords: condition monitoring, alarm, baseline, forecast, remaining life. Query: “What does this signal mean under the actual operating conditions?” Return a qualified condition account or the precise interpretation limit.MNT.1, MNT.3; FPF C.16

Part B - Readiness, Intervention Choice, Coordination, and Protection

§ID & TitleStatusKeywords & Search QueriesDependencies
5MNT.5 - Prepare Maintenance Service Capability, Spares, Tools, and AuthorityStableKeywords: spare applicability, tools, competence, readiness, lead time. Query: “Can the selected maintenance task obtain usable support in time?” Establish task-specific readiness or its action-changing deficiency.MNT.2, MNT.6; SYSE.12; FPF A.2.2
6MNT.6 - Diagnose Condition and Choose a Maintenance ResponseStableKeywords: diagnosis, repair, replace, defer, restriction, recommendation. Query: “What maintenance response is supported now?” Compare plausible maintenance responses and finish sufficient advice without compulsory physical work.MNT.3, MNT.4, MNT.5, MNT.7; FPF C.11.DUA
7MNT.7 - Coordinate Maintenance Intervention and Continuing OperationStableKeywords: outage, service capacity, preparation, testing, restoration, contingency. Query: “Does the whole intervention fit the operating commitment?” Compare complete elapsed demand with the qualified service envelope.MNT.5, MNT.6; OPS.10
8MNT.8 - Isolate, Make Safe, and Authorize the Maintenance InterventionStableKeywords: isolation, energy, protection, intervention permission, scope. Query: “What supports beginning this protected intervention?” Establish applicable actual protection and bounded authority, or return the unmet condition.MNT.1, MNT.5, MNT.7; FPF A.2.8.PER

Part C - Performed Intervention, Functioning, and Return to Use

§ID & TitleStatusKeywords & Search QueriesDependencies
9MNT.9 - Perform and Record the Maintenance InterventionStableKeywords: performed maintenance, deviation, interruption, actual parts, work record. Query: “What work actually occurred and in what resulting state?” Perform within operative conditions and preserve useful intervention evidence.MNT.6, MNT.8; FPF A.13, A.15.1
10MNT.10 - Verify Restored Functioning after MaintenanceStableKeywords: restored function, representative load, verification, test limits. Query: “What required functioning does the evidence support?” Check the actual resulting configuration and return qualified functioning evidence.MNT.9; FPF B.3, A.10, C.16
11MNT.11 - Hand Back and Authorize Resumed Use after Maintenance, with Certification Where RequiredStableKeywords: hand-back, release, certification, control, resumed use. Query: “Who can resume which use of the returned System?” Reconcile functioning, state and applicable release conditions while transferring control.MNT.8, MNT.9, MNT.10; FPF A.2.8.PER

Part D - Information, Programme, Methods, Simultaneous Work, and Culture

§ID & TitleStatusKeywords & Search QueriesDependencies
12MNT.12 - Maintain Maintenance Information and Configuration ContinuityStableKeywords: maintenance history, serial unit, configuration, effectivity, event coding.

14MNT.14 - Compare Maintenance Methods for Retention or ChangeStableKeywords: Method comparison, predictive maintenance, practical worth, variant, refresh.
