Which statement best describes how the terms 'overhauled' and 'rebuilt' are applied under Part 43?

• A. Overhauled applies to engines; Rebuilt applies to components.
• B. Overhauled and rebuilt are interchangeable.
• C. Overhauled means brand new; rebuilt means used.
• D. Overhauled means only cosmetic work; rebuilt means major work.

Answer: (A)

Under Part 43, these terms describe the level of restoration, and they apply differently to engines versus other components. An engine that is overhauled is taken apart, inspected, and worn or damaged parts are replaced as needed, then it is reassembled and tested to meet approved data and service limits, bringing the engine back to a serviceable condition. This is a major restoration aimed at returning the engine to specified performance standards rather than making it brand new. For other components, the term rebuilt is used to indicate a similar restoration process: disassembly, inspection, replacement of worn parts, and reassembly to a serviceable condition. The focus here is on restoring the component itself, not the entire engine. These terms are not meant to be interchangeable, nor do they imply cosmetic work or simply using a brand-new part. A rebuilt component is not a rebuild of the engine, and an engine that is overhauled is not described as rebuilt.
