Anyone heard of an STC that extends the recommended TBO of subject Continental from 1800 to 2000 hours?
 
Why would you want an STC to change a time that is just a recommendation and nothing more?
 
STC that extends the recommended TBO
There is/was a place in AR that used to advertise an "extension" with their O/H'd engines but I don't think it was an actual STC. However, as mentioned above there really is not a market for that type STC short of Part 135 ops which requires an approved maintenance program. However most 135 O/H extensions are done in house through the the local FSDO as part of their approved 135 OpSpecs. In Part 91 ops (except K) you can run your engines legally as long as the engine will run or make annual, hypothetically that is.

200hrs isn’t much anyway. I’d bet the average 0-200 can make it well beyond TBO anyway.
 
name one company using the 0-200 in part 135 ?
 
The reason I asked is a seller on EBay is advertising a 150 with O200 and a 2000 hour TBO. When I wrote him to question he said his Millenium cylinders have an STC that increases TBO to 2000. I say BS and he was mistaken as a cylinder manufacturer doesn't set TBO for an engine manufactured by someone else.

I don't believe there is even a cylinder manufacturer that will give a warrantee to 2000 hours.
you are correct on the TBO.
 
I think that engine, run right, will out live most owners. Why did it need a top OH?
 
My C-150 with an O-200 had a 2000 hour TBO. It had 2250 on it when I sold it.
 
Who else seen that this is for new engines built after 2012, that also carry ICAs mandating TBO.

Continental Motors Inc.(CMI) provides operational limitations and instructions for your engine along with the requirements for continued airworthiness as specified in the engine Operators, Maintenance, and Overhaul Manuals and Service Bulletins. The Time Between Engine Overhaul (TB

In 2012, Continental Motors introduced its Gold Standard Factory Rebuilt and New Engines. These engines incorporate improvements in technology and manufacturing processes that have allowed us to increase the TBO. The increased TBO is affective on nearly all Continental Motors Factory produced engines beginning in February 2012 as designated by serial number 1006000 and higher. Nearly all models will receive the benefit of a 200 hour increase over the existing TBO. Aircraft owners that fly 40 hour per month will receive up to 400 hours.

Did the 150 from post #1 have one of these engines?

Marginally increase market value, going from timed out to almost timed out?

I doubt it. He claimed 980 hours on an overhaul and 150 STOH when he put on the millennium cylinders. I would think if it were a factory rebuild he would have marketed it as such. He had no eBay history so I'm wondering if it was a
scam.

You can be assured if it has Superior Cylinders it is not a TCM overhaul or new engine.
 
Marketing! :)
Trying to keep up with Lycoming. They do claim that they improved the metallurgy some; I would hope so, since even small Continentals usually need at least valve work by mid-time or so.

I built a 0-200-A for a flying club way back in 2001, that now has 2950 hours since major, it has never had a cylinder removed, It has had all the accessories replaced, the mags have been rebuilt twice, but the 4 ECI cylinders have never been off. Last 100 hour the compressions were low 70s.

Then ECI used better valve and guide technology. That might have forced Continental to do the same. We had two 150s in the flight school and several more 172s, and those O-200s always needed top-end work at around mid-time while the Lycs just thundered on right up to TBO without any complaint whatever. Lyc has used sodium-filled exhaust valves for a long time, and changed the valve guides to a high-chromium-content bronze back in 1999 or so, and their valve issues mostly went away.
 
Do you want permission to run it over TBO? If so my dog says it is fine with her. :)
