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.

What is the difference between overhaul and rebuilt?

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.

How much does an aircraft engine overhaul cost?

It is recommended that most piston aircraft engines be rebuilt every 1,800 to 2,000 or so hours. This TBO time is set by the engine manufacture. Overhaul costs can easily run around $18,000 so an aircraft with a run-out engine will cost quite a bit less than one with a newly rebuilt engine.

How long does an airplane engine last?

Airline engines (for example the Rolls Royce Trent series) usually have TBOs of over 15000 hours. The record for maximum time for an engine on wing (i.e. use in aircraft before removal for overhaul) is well over 40,000 hours. The life of an engine is given by the manufacturer and are different for different engines.

What is a major engine overhaul?
