Aircraft Engine Overhaul Keeps Your Plane Healthy

Aircraft Engine OverhaulAn aircraft engine is literally the beating heart of an airplane, and an aircraft engine overhaul is the best way to keep the plane’s “heart” healthy and functioning smoothly.  Environmental conditions are just some of the factors that can play a major role in wear and tear on an aircraft engine, and an overhaul helps address those issues as well as many others.

Aircraft Engine Overhaul 

An aircraft engine overhaul involves removing, tearing down, cleaning, inspecting, repairing and testing all engine parts.  The time between overhauls is determined by each aircraft engine manufacturer, based on a combination of the hours of service and the age of the engine.  The average time between overhauls for most manufacturers is 2,000 hours.  

Reasons for Aircraft Engine Overhaul 

Aircraft engines function in less-than-friendly environmental conditions, with exposure to corrosive saltwater, dust, and dramatic climate changes—all of which can lead to internal corrosion.  In addition, engines that are subject to short-term use often need more frequent aircraft engine overhauls as short-term use results in increased condensation.  Engines in use for less than 40 hours per month will experience corrosion due to condensation, as the moisture does not evaporate off engine parts quickly enough.  Engine components experience significant expansion and contraction due to extreme heat during operation and rapid cool down upon landing.  Metal that is contracted and expanded often degrades, and parts break down due to friction.

Extend the Life of an Aircraft Engine 

The most important reason to undergo an aircraft engine overhaul is that the procedure will extend the life of an aircraft engine. An aircraft engine overhaul keeps the engine running smoothly and extends the life of the aircraft significantly.

Aircraft Engine Overhaul Prices: What You Need to Look For

One of the most important requirements in owning an aircraft is understanding aircraft engine maintenance, so an aircraft engine overhaul may be necessary to keep an engine running like new.  An overhaul consists of removing, disassembling, cleaning, inspecting and repairing an aircraft engine.  Costs can run high with the extensiveness of an aircraft engine overhaul, thus it is important to know what to consider before choosing an overhaul company.

Required                   

Aircraft-Engine-Overhaul-Prices-What-You-Need-to-Look-ForAircraft engine overhaul is always required – this is one of the most important things to remember. Based on the Time between Overhaul (TBO), every aircraft engine must be removed, dismantled, checked and repaired as necessary.  The engine, after being reassembled, is reinstalled in order to remain in service.  For most engines, the TBO is 1,800 to 2,000 hours, which means many years between overhauls for a plane not flown often.

Outsourcing

Asking an aircraft engine overhaul facility whether the work will be outsourced or done on-site is advised.  A company that outsources the overhaul, even if it is a segment of the work, loses quality control over service completion.  Therefore, be sure the facility you choose performs the work in-house.

Costs

Costs of an engine overhaul should be quoted based on the type of aircraft serviced and the time passed since the last overhaul.  Price can also vary on which series of overhaul the customer requests.  Facilities should not offer a “one-size-fits-all” price for aircraft engine overhauls.

Time

The time for completing an aircraft engine overhaul depends on the type of aircraft and the series of overhaul requested.  On average, an aircraft engine overhaul can take between two and three weeks, depending on the engine’s status and any approval delays from the customer for additional repairs.

When choosing a facility to perform an aircraft engine overhaul, it is important to look at what the price actually includes.  A good facility should be able to give you a rough estimate of the time needed, inform you if outsourcing is required, and give you a cost estimate based on the type of aircraft and the series of overhaul desired.  For more information on aircraft engine overhaul, join our online community on Facebook, Twitter and YouTube.

The Importance of Aircraft Engine Overhaul

Aircraft engine overhaul can significantly increase the resale value of an aircraft, but even more importantly, an overhaul can extend the life of an aircraft engine and make the aircraft safer to fly.  Normal wear on the metal parts of an aircraft engine can lead to tolerance increases and poor performance, which could eventually lead to engine failure.  In addition, an aircraft engine overhaul allows for mechanical inspection of the engine to diagnose an issue before it becomes a major problem.

Extend the Life of Your Engine

The-Importance-of-Aircraft-Engine-OverhaulOne 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.  Lubrication is necessary to avoid metal-to-metal contact that can damage engine parts and create an unsafe flying experience.  By performing aircraft engine overhauls as recommended by the engine manufacturer, the life of the plane engine can be extended significantly.

Better Performance

After an aircraft engine overhaul, many owners report a significant increase in performance, with the most notable improvement in engine vibration.  An engine overhaul allows the mechanic to analyze the various moving parts in the engine in order to adjust any out-of-balance internal parts.  The adjustment reduces engine vibration and improves thrust output.

Resale Value

Another important reason to perform regular aircraft engine overhauls is that it increases the resale value of an aircraft.   In fact, engine overhauls have been specifically listed in aircraft evaluation books at an increased value over planes that have not had an overhaul.  There are several lenders that add the full retail cost of an aircraft engine overhaul to the appraised value of an aircraft.  This further confirms that an overhaul of your aircraft engine can significantly increase the resale value of the aircraft.

Safety should be the prime factor in performing regular aircraft engine overhauls, but the fact that an aircraft offers better performance and significantly higher resale value are also excellent reasons for overhauling an aircraft engine.  If it’s time for an aircraft engine overhaul, reach out to Covington Aircraft.  We maintain, overhaul, and sell turbine and radial engines.  Call us at (918) 756-8320.

The Terminology and Standards of Aircraft Engine Overhaul – Part 3

As a final installment in our series of posts intended to demystify the aircraft engine overhaul process, we at Covington Aircraft want to detail the differences between using new and overhauled parts in an engine overhaul, so that you can make the best and most informed decision possible when TBO time comes around again.

When you’re looking to get an engine overhaul, a key point to remember is that the FAA does not require that all parts need to be replaced with brand new OEM equipment. While it is an accepted practice to replace parts such as pistons, rings, bushings, seals and gaskets, it’s also an accepted practice to reuse internal steel parts like connecting rods, the crankshaft, pushrods, gears and drive shafts, among others.

Testing and replacement

radial2

Even if they are reused, all non-new parts are carefully inspected and checked for cracks or defects via non-destructive testing techniques like Magnaflux and dye-penetrant tests. If a part fails to meet specified dimensional limits—either new limits or service limits, depending on the type of overhaul you’ve requested—it will be immediately rejected and replaced, regardless of the owner’s preference on the matter. The downside of this replacement is that some components come in matched sets, which means that a damaged single Planet gear may require the replacement of all Planet gears.

To overhaul or not to overhaul your parts?

When getting an engine overhaul, it can be difficult to decide if you should overhaul your existing cylinders or just replace them with new ones. New cylinders, if available, cost more than overhauling the cylinders you’ve already got. If your existing cylinders don’t have much wear, then it’s probably perfectly acceptable to get them overhauled and reinstalled. Remember that an overhauled cylinder still gets a new cylinder barrel choke and cylinder barrel honed finish, and the guides and seats are refurbished or replaced.

If you’re interested in further information on aircraft engine overhauls for turbine or radial engines, please let us know. We welcome questions and e-mails, and always strive to provide the best service possible to all our customers.

The Terminology and Standards of Aircraft Engine Overhaul – Part 1

This is the first post of two in our efforts to educate aviation enthusiasts, aircraft owners, and business fleet aircraft managers on the terminology of an aircraft engine overhaul.  If you are in need of maintenance or overhaul for your radial or turbine engine, make sure you visit Covington Aircraft’s website for more information!

When TBO time rolls around, are you ready to speak and understand the language enough to make an informed decision?

Air-Tractor-Landing-at-Hangar-1024x676Parents everywhere tell their children, “Read everything before you sign it.”  What good is this advice if you have no understanding of what you are reading?  Sure, many things are intuitive, but a clear understanding of what is offered for services further ensures that you will get value for your dollar.  The following is a listing and discussion of what various terms mean when it comes to aircraft engine overhaul. You may not know how to check the free-play on a valve tappet after reading this, but at least you should know your O.E.M from aftermarket enough to discuss your options.

Terms that are used and approved by the FAA.

NEW ENGINE:

A new engine is one that has been manufactured from all new parts and tested by an FAA-approved manufacturer.  The engine will have no operating history except for test cell time when received.  No FAA-approved manufacturer can approve another entity to manufacture or assemble a NEW ENGINE.

NEW LIMITS:

These are the FAA-approved fits and clearances manufacturers adhere to with new engine.  This may be accomplished using standard or approved undersized and oversized dimensioned parts.

SERVICE LIMITS:

The service limits are the FAA-approved allowable wear fits and tolerances to which a new limit part may deteriorate and still be a useable component.  This may also be accomplished using standard and approved undersized and oversized dimensions.

OVERHAULED ENGINE:

Chey-5-300x225An engine that has been disassembled, cleaned, inspected, repaired in accordance with manufacture overhaul instructions and tested using FAA-approved procedures.  The engine may be overhauled to new limits or service limits and still be considered an FAA-approved overhaul.  The engine’s previous operating history is maintained and it is returned to you with zero time since a major overhaul and a total time since new.  Of course, the total time since new is the same as before the overhaul.

REBUILT ENGINE:

This is an engine that has been overhauled using new and used parts to new limits by the manufacturer or an entity approved by the manufacturer.  The engine’s previous operating history is eradicated, even though the engine may have used components installed that have many hours of operating history, and it comes to you with zero hours total time in service

O.E.M. and AFTERMARKET:

When an engine is overhauled or rebuilt, the new parts that are used during the repair process can come from a variety of sources.  An “O.E.M.” part is a new part that is manufactured by the original engine manufacturer to stringent FAA standards.  An “aftermarket” part is a new part that is manufactured by someone other than the original engine manufacturer and meets or exceeds the same stringent FAA guidelines as a new O.E.M. part.

So, now you know enough to be dangerous! However, put your aircraft engine overhaul into the hands of the experts who have performed thousands upon thousands, either at the Hangar in Okmulgee, OK or wherever you are located, and give Covington Aircraft a call today!  Next week we will go over some other aircraft maintenance terminology. Happy Flying!
