Aviation Glossary :: Major Overhaul  Aviation Glossary :: Major Overhaul FAA Written Test Preparation
Aviation Glossary Welcome to the Dauntless Aviation Glossary!

At Dauntless, our editorial staff maintains the web's largest unified glossary of aviation terms. This glossary is built from a combination of official, quasi-official, and proprietary sources (including original material that we develop oursselves). Uniquely, we often provide multiple definitions of a given term so that you can find that which best applies to you. In order to maximize your learning efficiency, this glossary (and similar ones for our international users) is incresingly fully integrated into our aviation learning apps, including our FAA written test prep and FAA practical test prep software and apps. If you like this glossary, you'll love them with their polished learning environments and world's best and clearest content (please do give them a try.).

Overhaul. In the general aviation industry, the term engine overhaul has two identifications that make a distinction between the degrees of work done on an engine:
  1. A major overhaul consists of the complete disassembly of an engine, inspected, repaired as necessary, reassembled, tested, and approved for return to service within the fits and limits specified by the manufacturer's overhaul data. This could be to new fits or limits or serviceable limits. The determination as to what fits and limits are used during an engine overhaul should be clearly understood by the engine owner at the time the engine is presented for overhaul. The owner should also be aware of any parts that are replaced, regardless of condition, as a result of a manufacturer's overhaul data, service bulletin, or an ariworthiness directive.
  2. Top Overhaul consists of the repair of parts outside of the crankcase and can be accomplished without completely disassembling the entire engine. It can include the removal of cylinders, inspection and repair to cylinders, inspection and repair to cylinder walls, pistons, valve-operating mechanisms, valve guides, valve seats, and the replacement of pistons and piston rings. A top overhaul is not recommended by all manufacturers. Some manufacturers indicate that if a powerplant requires work to this extent, it should be given a complete overhaul.
