# FOD Prevention Program Checklist for Aerospace Manufacturing > Source: https://netray.co/tools/fod-prevention-program-checklist > Publisher: Netray (netray.co), AI and integration engineering for ERP and manufacturing systems. > Section: Free Tools ## Short answer Check your foreign object debris program across tool control, housekeeping, training, work area rules and audits. ## Category aerospace-defense ## Industry Aerospace ## Audience - Quality manager - Production supervisor - EHS manager ## Tool **Kind:** checklist **Scoring Note:** Score is the share of items marked complete. Critical items should be closed before an aerospace customer audit. NAS 412 (the foreign object damage prevention guide) and customer clauses are the usual references; check which apply to your contracts. **Groups:** #### Program and responsibility **Items:** **Text:** A written FOD prevention procedure exists and is controlled in the QMS **Critical:** true **Text:** A FOD focal point or coordinator is named with defined authority **Critical:** true Customer-specific FOD requirements are identified in contract review FOD is covered in management review inputs or quality metrics FOD incidents are recorded and investigated with root cause Suppliers are flowed down FOD requirements where product is exposed #### Tool and hardware control **Items:** **Text:** Tools are inventoried with shadow boards or kits and a check-out record **Critical:** true Tool counts are verified at start and end of each shift or task **Text:** Lost tool procedure stops work until the tool is found or accounted for **Critical:** true Consumable hardware (fasteners, washers, clips) is issued by count and returns are reconciled Personal tools and unauthorized items are controlled or prohibited in critical areas Broken tools are retrieved and fragments accounted for before work continues #### Housekeeping and work area **Items:** **Text:** Clean-as-you-go is required, with debris removed before closing any cavity or panel **Critical:** true Work areas have defined clean zones with entry rules Vacuuming, not blowing with compressed air, is used to remove chips and debris Designated containers exist for trash, chips and hazardous waste Floors, benches and machine tables are inspected at set intervals Cavities, ducts and fuel or hydraulic openings are covered when not being worked Lighting is sufficient to inspect for debris inside assemblies #### Personnel and training **Items:** **Text:** All people entering production areas receive FOD awareness training **Critical:** true Training records are kept and refreshed on a defined cycle Pocket and clothing rules are defined (no loose items, jewelry, badges on loose cords) for critical operations Visitors and contractors are briefed before entering the floor Employees can report FOD hazards without penalty #### Inspection and closing operations **Items:** **Text:** Final FOD inspection is a required sign-off before closing or sealing an assembly **Critical:** true Borescope or mirror inspection is available for enclosed areas Photographs or records capture the pre-closure state of critical assemblies where required Packaging operations include a FOD check and clean packaging materials Shipping containers are cleaned and inspected before loading #### Audits and improvement **Items:** **Text:** Scheduled FOD walks are performed and recorded **Critical:** true Findings from walks drive corrective actions with owners and dates Trends (chips on floor, lost tools, escapes) are reviewed monthly Lessons from customer escapes or returns feed back into procedures ## Content **Intro:** Foreign object debris causes damage and failures that are costly and sometimes dangerous. A FOD program that exists only as a poster fails when audited. Use this checklist to test whether your plant has controls on tools, housekeeping, training, closing inspections and audit follow-up. **Sections:** #### How to use the checklist **Body:** Walk the floor with the checklist rather than answering from the office. Tick an item only when you see evidence: a tool shadow board with a sign-out log, a closing inspection signed on a traveler, a training record. Mark critical items first. The score is a view of coverage, and the notes you add to each failed item become your corrective action list. **Bullets:** - Walk at least one shift change to see tool counts in practice - Interview operators, not only supervisors - Photograph good and bad examples for training - Re-run quarterly and compare scores #### Where the requirements come from **Body:** AS9100D clause 8.5.1 asks for controlled conditions for production, and customers often add FOD clauses referencing the NAS 412 foreign object damage and foreign object debris prevention guide. AS9100 also requires prevention of foreign object damage in its requirements for product preservation and production control. Your contract determines how detailed the program must be, so list every customer flow-down in contract review. #### What good looks like **Body:** Good programs make loss visible. Tools sit in kits where a missing item is obvious. Chips are removed by vacuum before an assembly is closed. A final FOD inspection is a signed operation, not an assumption. When a tool goes missing, work on the affected unit stops until it is accounted for. Trends are reviewed, so a rising count of floor debris triggers action before a customer escape. #### Common mistakes **Body:** Typical gaps are compressed air used to clean assemblies, no closed-loop for lost tools, training that stops after onboarding and FOD walks with no recorded findings. In an ERP or MES, add a FOD check operation to routings for closing steps so the sign-off is enforced rather than remembered. **Cta:** If you want closing-operation FOD sign-offs enforced in your routings and visible in dashboards, we can help configure that in your ERP or MES. **Faq:** #### What is the difference between FOD and FOD? **Answer:** The same letters cover two terms: foreign object debris, the material itself, and foreign object damage, the harm it causes. A prevention program targets the debris so that damage never happens. Most manufacturing programs and the NAS 412 guide address both meanings together. #### Is compressed air allowed to clean parts? **Answer:** Many aerospace programs prohibit blowing debris with compressed air in or near assemblies because it can drive chips into cavities. Vacuum collection is the usual rule. Check your customer and company procedures, since some allow controlled use in specific cleaning steps. #### How often should FOD walks happen? **Answer:** There is no universal figure. Many plants do a short walk each shift in critical areas and a documented audit weekly or monthly. Set the frequency by risk and past findings, and record the results so you can show the program is working. #### Does the checklist replace a customer FOD audit? **Answer:** No. It is a self-assessment that helps you find gaps before a customer or registrar does. Your customers may have their own audit forms and acceptance criteria, which take priority for their contracts. ## Search terms FOD prevention checklist, foreign object debris checklist, FOD program audit, NAS 412 FOD, FOD prevention aerospace manufacturing, FOD walk checklist, tool control FOD, FOD prevention plan template --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
