The TBO figures published by Lycoming and TCM are not airworthiness limitations. Here are a few of the most common misapprehensions about TBO: Nonsense. TELEDYNE CONTINENTAL ® AIRCRAFT ENGINE . Recommended service bulletins are used for conveying helpful hints to owners and mechanics, but they are merely suggestions and compliance is strictly up to the individual operator.M91-8 is one of these lowest-priority service bulletins. There is no performance change. In other words, if you’re still kicking at age 75, you can expect on average to live until age 86. $550.00. The STC is Issued on per engine serial number basis. Furthermore, in those rare cases when these components do fail (e.g., crankshaft fracture), the failure is almost never correlated with time since overhaul. Continental C75-12: By the early 1940s, Continental had pushed the 171 in³ 4-cylinder A-series engines as far as it could. Don't exceed rpm limits. Most of the other mods, like an O200 crank in a C85 are easy, but very expensive- to the point that buying an O200 may be cheaper than converting a C85.

Those in the latter group are no more obligated to comply with published TBO than are Part 91 operators. Any operation beyond these periods is at the operator’s discretion and should be based on the inspecting mechanic’s evaluation of engine condition and operating environment. 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. 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). Aircraft owners that fly 40 hour per month will receive up to 400 hours. Will I recondition the cylinders or install new ones? I imagine I’ll be flying behind them for a while longer (knock on wood).This time around, I’m not even the slightest bit nervous about continuing to fly past TBO. But these “bottom end” components are seldom implicated in catastrophic engine failures. Supersedes M87-11 REV. If you exclude fuel starvation or exhaustion (i.e., pilot error), most engine stoppages involve mechanical failure of some “top end” engine component like a cylinder, exhaust valve, piston, magneto, turbocharger, exhaust stack, etc. Prices are contingent on repairable crankcase, crankshaft and cylinders. There are lots of TBO-related old wives tales that are widely believed by owners and mechanic alike, and they can cost owners a great deal of money. Those engines and cylinders now have accumulated another 1,600 hours since the overhaul, and so those cylinders have 3,500 hours on them. 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. Nearly all models will receive the benefit of a 200 hour increase over the existing TBO. This figure would also be appropriate for adjusting the “blue book” value of my airplane to account for higher- or lower-than-average engine time.Does this mean that I should have euthanized my engines when they reached 1,400 hours SMOH (since major overhaul), despite the fact that they were running great, had excellent compressions, low oil consumption, no metal in the oil filters, and excellent oil analysis reports? We just did this to my friend's C 140. The overhaul periods listed are recommendations only. Factory Quote.

These recommended overhaul periods in no way alter TCM’s warranty policies. Our aircraft engine cylinder shop offers our customers repair and overhaul capabilities for their cylinder needs. 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. 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.

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. Continental has a break-in section in their overhaul manual. Engines used in frequent type service have an additional 200 hour increase. No, I don’t think so. I certainly hope not! Mandatory service bulletins are less urgent, normally not accompanied by an AD, and normally “mandatory” only for commercial operators. These are complex decisions that I discuss at considerable length in my Savvy Owner Seminar. 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. 14 watching. 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. 2, SB97-6, 6A.

It offers recommendations, but they are not intended by TCM to be obligatory for any operator. Not so. The wording of TCM’s service bulletin M91-8 makes it explicitly clear that: Bottom line is that if an engine is still going strong when it reaches TBO, there’s absolutely no reason to consider removing it from service for major overhaul, and every reason to continue flying until it starts showing signs that overhaul is warranted.

The accomplishment of cylinder leakage checks and spectrographic oil analysis may be helpful in making this determination. Click here for Press Release. (An engine may also become unairworthy long before reaching TBO.). These engines incorporate improvements in technology and manufacturing processes that have allowed us to increase the TBO. Continental Motors has increased TBOs up to 400 hours on Gold Standard Factory produced engines. (As previously noted, many commercial operators routinely run their engines to 150% of manufacturer’s TBO with the FAA’s official blessing.). Free shipping.
