## Technical Meaning and Practical Use

A hard-time component must be removed, overhauled or replaced at a specified interval rather than being left in service solely based on observed condition.

Aviation Glossary

**Term:** Hard-Time Component

**Category:** Airworthiness & Maintenance

## Where It Sits in Continuing Airworthiness

Hard-Time Component 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

Hard-time limits may be set by approved maintenance data, life limits or the operator's maintenance program.

## 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.
