## Definition, Documents and Application

The Aircraft Maintenance Manual, or AMM, is manufacturer-approved maintenance data containing procedures for inspection, servicing, removal, installation, adjustment and other aircraft maintenance tasks.

Aviation Glossary

**Term:** Aircraft Maintenance Manual

**Category:** Airworthiness & Maintenance

## Where It Sits in Continuing Airworthiness

Aircraft Maintenance Manual forms part of the technical framework used to establish, maintain or document aircraft airworthiness. Applicability depends on aircraft type, authority, approved maintenance data and the operator's maintenance programme.

## How It Is Used

Technicians use the current applicable revision and must follow referenced tooling, limits and safety precautions.

## Records and Transaction Impact

Technical status must be supported by current records. Buyers, lessors, lenders and MRO organizations normally verify the applicable document, revision, compliance status and remaining maintenance exposure rather than relying on a description alone.
