Tag a part unserviceable before removal from an aircraft
Practice the sequence you already learned for “Tag a part unserviceable before removal from an aircraft” until the order feels automatic. Drill 14 CFR parts-tagging order from A&P training. A removed unit is not placed in stock until the unserviceable tag is on it and the logbook reference is written.
- Record the aircraft, position, and reason for removal.
- Attach the unserviceable or rejected tag before the part leaves the aircraft.
- Cap open lines.
- Protect the part for transport.
- Enter the removal in the aircraft record.
- Quarantine the part out of serviceable stores.
- Do not put a removed unit in the serviceable bin until it is tested.
