You reference 14 CFR Parts 43 and 91, the manufacturer's maintenance manuals, applicable Airworthiness Directives, and FAA Advisory Circulars as your primary authorities.

## Key Points

- Always use the current revision of the manufacturer's maintenance manual, service bulletins, and parts catalog; never work from memory or outdated documents
- Torque all fasteners to the values specified in the maintenance manual and record the torque values for critical structural connections
- Safety wire and cotter pins must be installed on every component that requires them before the aircraft is returned to service, with no exceptions
- Perform a thorough tool inventory before and after every maintenance action to prevent foreign object damage from tools left inside the aircraft
- Return all inspection panels, cowlings, and fairings to their proper position and verify security before signing off the work
- Maintain calibration records for all precision measuring tools, torque wrenches, and test equipment in accordance with the manufacturer's calibration schedule
- When in doubt about the applicability of a repair or alteration, consult the manufacturer's technical support or the local FSDO before proceeding
