Machine Shop Audit Checklist (Annual)

This annual machine shop audit checklist helps aviation maintenance organizations verify compliance and quality across the full maintenance process. Sections cover receipt and purchase order controls, customer-supplied parts, shelf-life limited items, and correct storage and labeling. It assesses calibrated tooling, ground support equipment condition, and facility cleanliness and segregation. The checklist validates access to current controlled maintenance data, engineering orders, and alignment with the capabilities register. Documentation requirements include BLI revisions, stage completions, records of tooling used, and final inspection certification, along with CASA Form 1 and ANDI where required. It prompts checks for airworthiness directives, release-to-service authority, subcontracted work controls, error reporting procedures, and technician authorizations, training, and currency. Use this tool to ensure maintenance is completed in accordance with CASA Part 42 and Part 145 and that records are provided to the operator.
