What does the maintenance checks in Phase 4 immediately follow?

The maintenance checks in Phase 4 directly follow the previous maintenance weeks that occur after Phase 3. This sequence is important because Phase 4 focuses on conducting maintenance checks that ensure the accuracy and effectiveness of the maintenance performed in prior phases.

Phase 3 typically encompasses various maintenance activities, including planned maintenance system (PMS) tasks, and the checks in Phase 4 serve to verify that these tasks were completed correctly and that the systems and equipment are functioning as intended. This continuity is crucial for maintaining operational readiness and ensuring that any deficiencies identified during Phase 3 are addressed.
