This checklist helps you check each one before the audit. **Sections:** #### How to use the checklist **Body:** Assign each group to the person who owns the area, such as quality for manuals and corrective actions, stores for parts, and the training coordinator for people records. Ask them to tick an item only when they can show the evidence. Review unticked critical items in a weekly meeting until the audit date. Export the list to PDF at the end so the pre-audit review itself is on record. **Bullets:** - Tick only with evidence in hand - Name an owner for each unticked item - Rehearse the retrieval of a few random records #### Where findings usually come from **Body:** Most findings are not about missing procedures. They come from a gap between the written procedure and what staff do, a missed expiry date or a record that cannot be found in time. For that reason, spot checks beat document reviews. Pick a recent work order and follow it from induction to release, checking the data used, the parts fitted, the tools used and the people who signed. If the trail breaks anywhere, the audit would find it too. #### Common mistakes **Body:** Teams often start preparing a week before, discover systemic gaps and patch them with paperwork, which auditors recognise quickly. Another mistake is closing a corrective action with a retraining note instead of fixing the cause. Make sure each action addresses why the problem occurred, check later that it worked, and keep the evidence where the auditor can find it. This list is a general aid and does not replace the requirements of your regulation or your approved system. **Bullets:** - Do not backdate records - Verify, do not just close, corrective actions - Confirm requirements with your authority **Cta:** If audit evidence lives in several systems, we can set up a private search over your records so owners can pull proof quickly and in a read-only way. **Faq:** #### Does this work for both FAA and EASA? **Answer:** It covers topics common to both, such as manuals, authorisations, tooling and records. The regulatory text differs, so check items against the specific rule set that applies to your approval, and add any local requirements. #### How often should we run it? **Answer:** Run it before any external audit and at least once per internal audit cycle. Some stations review the critical items monthly, because expiry dates and calibration status can lapse between audits. #### Who should complete the checklist? **Answer:** The quality manager usually coordinates it, but area owners should confirm their sections. An independent person, not the owner, should verify a sample of ticked items. #### Is passing this checklist the same as passing the audit? **Answer:** No. It is a preparation aid and cannot cover every requirement. Auditors may sample areas that you did not expect, so keep the whole system healthy, not only the items on the list. ## Search terms part 145 audit checklist, repair station audit preparation, faa part 145 checklist, easa part 145 audit, mro internal audit checklist, repair station manual review, maintenance organisation exposition audit --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
