3	MNT.3 - Establish Degradation and Failure Evidence for Maintenance	Stable	Keywords: 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
4	MNT.4 - Monitor and Interpret System Condition for Maintenance	Stable	Keywords: condition monitoring, alarm, baseline, forecast, remaining life.

5	MNT.5 - Prepare Maintenance Service Capability, Spares, Tools, and Authority	Stable	Keywords: 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
6	MNT.6 - Diagnose Condition and Choose a Maintenance Response	Stable	Keywords: diagnosis, repair, replace, defer, restriction, recommendation.

8	MNT.8 - Isolate, Make Safe, and Authorize the Maintenance Intervention	Stable	Keywords: 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 & Title	Status	Keywords & Search Queries	Dependencies
9	MNT.9 - Perform and Record the Maintenance Intervention	Stable	Keywords: 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
10	MNT.10 - Verify Restored Functioning after Maintenance	Stable	Keywords: 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
11	MNT.11 - Hand Back and Authorize Resumed Use after Maintenance, with Certification Where Required	Stable	Keywords: 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 & Title	Status	Keywords & Search Queries	Dependencies
12	MNT.12 - Maintain Maintenance Information and Configuration Continuity	Stable	Keywords: maintenance history, serial unit, configuration, effectivity, event coding. Query: “Which history and description apply to this installed state?” Restore event and configuration continuity for the receiving decision.	SYSE.13; MNT.3, MNT.9
13	MNT.13 - Coordinate the Maintenance Programme and Fleet Learning	Stable	Keywords: fleet, programme, failure rate, exposure, support, improvement.
