Does anyone know what is the cost for converting an IO-360 KB to an IO-360KB-C-GB? Noise restrictions in this part of Europe (Spain, France, Italy, Portugal) are not really an issue, as far as small piston engines go, it is though up North. Restrictions only affect airliner operations during night hours. In Spain, for example, there are only two check points in Madrid and Barcelona respectively. Aparently they are extremely expensive. The National Agency incharged of running the airports has spent several million Euros installing soundproof windows in houses close to airports.
The Aviation Authorities in my area are much more flexible when dealing with a classic airplane and thay will aprove any work on the plane as long as it is signed by an FAA IA. If it were another airplane, there is no way I could do it, because then I would need an EASA (European Aviation safety Agency) STC, and those are very hard to find over in the U.S. Every item installed on the plane has to be EASA certifyed. It seems as though Europe is trying to protect its industry from you guys and has started a burocracy war. Hopefully it wont last for too long, becaue it is the stupidest thing they've done lately, and they've done a few...

You see that little "flash" of light behind my left wing??? right over there in the water??? And the "smear" of light trailing off my left wing?dacker wrote:George, is that airplane going backwards?![]()

That's the "light" (travelling at 186,000 miles per second) trying to keep up. (Joe is groaning somewhere.)

Re: TCM IO-360 CONVERSION
I think the ISHAM 172K model STC kit is worth about $ 2000- $5000 depending on the options you select, probably the average at $3000. I don't know whether it applies to the 170 or whether the XP kit if available is rated at 210.

Re: TCM IO-360 CONVERSION
O.K. I was waiting for somebody else to ask. George I have not heard the term "Flat rated" applied to piston engines. I understand I think the application to turbines. Could you elaborate?

Re: TCM IO-360 CONVERSION
From What I've red so far, it is rated at 210 with the 5 minutes limit for take off on the XP, I'm trying to findout if it's suitable for the 170. Thanks!

Re: TCM IO-360 CONVERSION
The "flat rated" terminology refers to a power setting limitation that is "flat" from takeoff to the altitude at which full throttle/rpm equals the takeoff power rating. (In other words, as already mentioned, it's an artificially reduced power setting, something less than "maximum rated" power, similar to the way the term is used with regard to turbines.)c170b53 wrote:O.K.

Re: TCM IO-360 CONVERSION
Our charity has three TCM IO-360 engines, one is an IO-360C, an IO-360 A6B and an IO-360 A8B.
It looks like we may have a Cessna 170a in our future. It could be a good plane to use in the bush where we work in Guatemala, providing bush air ambulance service to the Mayan villages. I wish there were some way to match our over-abundance of engines with the 170a by way of an XP conversion but that looks like a part of history now. Does anyone have any suggestions.

Re: TCM IO-360 CONVERSION
If it was my call, I'd find out how fussy the Guatamalan equivalent of the FAA is. It could be that if the airplane was registered in their country you could get by without an engine mount "blessed" by the FAA. After all, that is the pricipal hangup in making that conversion.

If you get to San Lucas Toliman, stop at the mission and ask for Fr Shaffer, he has a long working relationship with the gov. there and may be can put you intouch with the right person to get done what you need....good luck and post back with and update later.rrice wrote:Our charity has three TCM IO-360 engines, one is an IO-360C, an IO-360 A6B and an IO-360 A8B.
