During Post Maintenance Checklist Technician found Left-Hand MLG Uplock Hook with worn bushing. This is the third time in a month we have seen this issue. I recalled when we did the Phase 1-4 inspections; [we did] a specific task to inspect the uplocks. I checked the Maintenance Manual and found Task XXXX001 Uplock Detailed Inspection is to be performed every 300-hours. I performed a search in [our] Maintenance/Inventory Tracking Program and the Approved Aircraft Inspection Program (AAIP) and cannot find the task anywhere. It is my belief that since we have been doing the Phase-A and Phase-B Inspections that this task has been overlooked.Recommend that Task Card XXXX001 Uplock Detailed Inspection needs to be incorporated into some kind of scheduled maintenance event.
An Aircraft Maintenance Technician reported finding a third Cessna CE-560XLS aircraft in a month with Main Landing Gear Uplock Hook bushings worn during their Post Maintenance Checklist inspections. Technician believed that since they have migrated from doing Phase 1-4 Inspections to performing Phase-A and Phase-B Inspections; the Uplock Detailed Inspection Task has been overlooked.
