## How the Term Is Used in Aviation

On-condition maintenance keeps a component in service while it meets defined inspection or performance criteria instead of removing it at a fixed overhaul interval.

Aviation Glossary

**Term:** On-Condition Maintenance

**Category:** Airworthiness & Maintenance

## Where It Sits in Continuing Airworthiness

On-Condition Maintenance 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

The maintenance program specifies the tests, limits and inspection methods used to determine continued serviceability.

## 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.
