What is the difference between an overhaul and a rebuild?
A “rebuilt” engine should be put back into like-new condition, with all parts examined and replaced if they aren’t within new tolerances. An “overhauled” engine has new parts installed when they are worn beyond limits, but many are left in place because the wear limit hasn’t been exceeded.
When should an aircraft engine be overhauled?
Times typically run between 1,500 and 2,500 hours and there’s usually a calendar factor of about 12 years so the guidance is for whatever comes first. Piston aircraft engines are extremely reliable when properly maintained, when flown regularly and correctly.
Why do we need to overhaul the aircraft?
One of the most important reasons for aircraft engine overhaul is that the process extends the life of the engine, much as a tune-up extends the life of a car engine. Aircraft engines are subjected to rapid heating and cooling during and after a flight and this can put stress on the engine parts.
How many times can an aircraft engine be overhauled?
Engines- in theory they can be overhauled indefinitely. In fact, overhauls are only a recommendation for non commercial ops. Real world- after 2-3 overhauls may as well exchange for a 0 time already overhauled or rebuilt engine.
Why is overhauling necessary?
An engine overhaul is an excellent option for engines that aren’t old or excessively worn but are still experiencing issues. In many cases, an engine overhaul can effectively fix any issues with your engine and save you a significant amount of money over having your engine replaced completely.

How often do you have to overhaul an aircraft engine?
, Instrument-rated private pilot. In small aircraft, how often do engines have to be overhauled? Typically, a piston engine of small aircraft will have a recommended TBO (time between overhaul) of 1,500 to 2,000 hours. If the aircraft is used for commercial purposes, the TBO is mandatory.
Is your aircraft engine ready for an overhaul?
This engine was ready for an overhaul. The inside of the aircraft engine is subject to its own atmospheric climate that can be very hazardous to the internal steel parts it contains. When the engine is warmed up and cooled down in the normal routine of operation, there can be a significant amount of condensation that accumulates inside.
What is the definition of overhaul in aviation?
Apart from that usage, the term MRO (Maintenance, Repair and Overhaul) seems to be used in the airline industry to describe maintenance facilities, but there isn’t any specific definition that I could find. So there’s no single definition of “overhaul”.
