The purpose of a major engine overhaul is to inspect, recondition and or replace the engine’s “bottom end” components — crankshaft, camshaft, crankcase, gears, bearings, etc. The only things that will impact the overhaul cost are an unserviceable crankshaft or a cracked crankcase, and neither of those items are any more probable for an engine operated beyond TBO.By the way, it’s not just owners who hold these misconceptions. No * Most engine models manufactured after February 2012 have a TBO increase of 200 hours. In my view, the best way to think about published TBO is the way we think about human life expectancy statistics.According to the National Vital Statistics Report published by the Centers for Disease Control, the current life expectancy at birth for a white male in the United States is 75 years. We have 261 CONTINENTAL Airplane Engines for sale.

Our team of highly trained and licensed professionals are here to serve you. The Continental O-190 (Company designations C75 and C85) is a series of engines made by Continental Motors beginning in the 1940s. Since TCM’s published TBO for its TSIO-520-BB engines is 1400 hours, those engines were pretty much “run out” when I acquired the airplane (and the price I paid was adjusted downward accordingly).At 1,400 hours those engines were still running superbly, and all signs pointed to them being in great shape. It offers recommendations, but they are not intended by TCM to be obligatory for any operator. I know that so long as I continue to keep a watchful eye on compression, oil consumption, oil filter inspection, oil analysis, temperatures and performance, I’ll know when the engines are getting tired and it’s time to overhaul them. Converting the A65 to a C75 or A80 is the next easiest. Want to read more from Mike Busch? Those engines and cylinders now have accumulated another 1,600 hours since the overhaul, and so those cylinders have 3,500 hours on them. Consequently, there’s no longer any real advantage to overhauling sooner rather than later. An engine may be long past TBO and still be legally airworthy. CATEGORY 3 . Engine TBO (time between overhauls) seems to be one of the most misunderstood concepts in aviation maintenance. Customers that fly-in to Sebring, FL SEF will get a deep discount on engine removal and installation with an engine overhaul. Divco can do the machine work required. Click here for Press Release.

Engine overhaul should be performed “on condition” based on the inspecting mechanic’s evaluation of engine condition, based on compression checks, spectrographic oil analysis, oil consumption, and subjective assessment of engine performance (e.g., throttle response, power, smoothness of operation). Calendar time also affects this condition and should be taken into account.Particular attention should be paid to throttle response, power, smoothness of operation, oil consumption, to the proper use and maintenance of oil and air filters, and adherence to the recommended oil change periods. WORLD'S PREMIER INDEPENDENT AVIATION NEWS RESOURCE. Continental Motors has increased TBOs up to 400 hours on Gold Standard Factory produced engines. The definitive word on the subject of TBO for engines manufactured by Teledyne Continental Motors is TCM Service Bulletin M91-8 — “Recommended Overhaul Periods for All Teledyne Continental Motors Aircraft Engines” — dated July 10, 1991.

We just did this to my friend's C 140. No, I don’t think so. As Glenn suggests fly at varying power at low density altitudes. Furthermore, if you are still alive at age 86, your life expectancy is 6 years so on average you can be expected to live until age 92.Similarly, according to TCM Service Bulletin M91-8, the “life expectancy at birth” (recommended TBO) of TSIO-520-BB engines (like the ones in my 1979 Cessna T310R) is 1,400 hours. Continental Engine, Model No. Although TCM doesn’t publish figures for “life expectancy at 1,400 hours” for these engines, it only stands to reason that TSIO-520-BB engines that are in good shape at 1,400 hours surely have a good deal of useful life left in them. No, not at all. 470 Series Overhaul. It has a new crank, new pistons and reconditioned rads.

Nearly all models will receive the benefit of a 200 hour increase over the existing TBO. Both Lycoming and TCM publish engine TBOs in the form of non-mandatory service bulletins. Here are a few of the most common misapprehensions about TBO: Nonsense. The accomplishment of cylinder leakage checks and spectrographic oil analysis may be helpful in making this determination. Cylinders delivered after 3pm will count as next day). This is the document in which TCM publishes a table of recommended TBOs for all TCM engine models.TCM service bulletins come in three different grades: recommended, mandatory, and critical. It was clear from the results of the teardown inspection that those engines could have gone considerably longer — at least another 500 hours — with no problem.Those engines received minimalist (i.e., el-cheapo) major overhauls in 1990.

Will I recondition the cylinders or install new ones? (If a crankshaft is going to fail, it’s most likely to fail during the first few hundred hours after manufacture, or after a prop strike.). (An engine may also become unairworthy long before reaching TBO.). Subject to applicable airworthiness directives and service bulletins. To underscore this point, let’s take a look at exactly what TCM says in M91-8 (emphasis mine): Thousands of hours of operating experience indicate that Teledyne Continental Motors (TCM) aircraft engines, when operated within prescribed limitations, instructions and recommendations, can be operated between overhauls for the number of hours listed in the following table.

I wound up flying those engines trouble-free to 1,900 hours (500 hours past published TBO), at which time I started getting nervous and pulled the engines for major overhaul.As it turned out, my nervousness about flying those engines 500 hours past published TBO were completely unfounded. I’m not even going to try to predict how much more useful life those engines have left, but when the time comes to major them, they’ll tell me.I haven’t yet decided exactly what I’ll do when that time comes. Don't exceed rpm limits. Will I have the engines field overhauled again, or exchange them for factory-rebuilt engines? In those days, if you pushed an engine to the point that its cylinders could not be reconditioned, you’d have to spend more at overhaul to buy new ones. Continental C-series Aircraft Engines and their Derivatives The C75 and C85 by Kimble D. McCutcheon Published 25 Feb 2018.

There is no performance change. Those in the former group might theoretically be required to overhaul at published TBO, but most such operators request TBO extensions from their FSDO and these are routinely granted, often for as much as 50% over the engine manufacturer’s published TBO. Furthermore, in those rare cases when these components do fail (e.g., crankshaft fracture), the failure is almost never correlated with time since overhaul. $23,564 for Factory Rebuilt Exchange 5 Week Turnaround; Reputable Overhaul Shop 1 FAA APPROVED .

The compressions are all 75/80 or better, the oil consumption remains about a quart in 15 hours, the oil filters are clean, the oil analysis is excellent, and the engines are running as well as they ever have. Such bolt-on components are routinely replaced during normal maintenance without any need to overhaul the engine. But these “bottom end” components are seldom implicated in catastrophic engine failures. Most policies only require that the aircraft be airworthy and in compliance with FAA inspection requirements. Ask any aircraft owner what the TBO is for the engine(s) on his aircraft and you’ll almost always get the correct answer without hesitation: “My engine has a 1,700-hour TBO.” But ask that owner to explain the significance of that TBO figure and you’ll get all sorts of answers, most of them flat wrong. But w/o a MP gauge or airframe factory power vs altitude data go up to about 5000' DA where full throttle is about 75% power. These engines incorporate improvements in technology and manufacturing processes that have allowed us to increase the TBO.
