They have started production of individual components - some six hundred cylinders for example have been made. They are currently making a small batch of ten M9F engines (430-hp) for us, but largely from existing unused parts. The good news however is that their production schedule over the next year will include fifty totally new M14P engines, and building up from that. However I am sure much more expensive than in the past. A problem however is the availability of bought-in components such as magnetos and carburettors, of which new items are simply not available in production quantities. Nevertheless testing of their electronic fuel injection system is going well, as is electronic ignition. In any case there are Western analogues for these if needed.

I had only one aim, which was to stop AMATEURS making such modifications. If, however, those who are doing the modifications know enough of the original control surface design data; know the materials of which the original surfaces were made of; do proper structural designs; restore the mass-balance position, and most importantly, do theoretical and practical flutter tests (and that doesn't mean diving beyond VNE alone), then absolutely fine. I have no idea of the technical background of the organisations/people who are doing such modifications, and it is likely that they are skilled and capable. I am simply advising those who are not skilled and knowledgeable in such areas, that modifications of control surfaces are perilous unless you know exactly what you are doing. If you have seen the effects of control surface flutter, as I have, you will understand. It will turn a flying aircraft to twisted metal in a couple of seconds. In passing, I once had a flutter on an elevator trim tab on a Yak-52 (when the linkage separated), and when it reached a critical speed, I thought the whole aeroplane was going to come apart - and that for a little trim tab!

I received probably the same set of emails defending the mods. I am neither against metalized control surfaces nor do I think they are inherently unsafe. I was just thinking about the risk/reward ratio for doing them. Metal control surfaces are common and work well. Most airplanes have them. But they must be designed and balanced properly. The stronger they are, the more they will mass. And the more they mass, the more balancing weight needed. When you remove them to paint them and then replace them, they must be rebalanced. If someone makes a mistake there *may* be a problem. Fabric-covered surfaces don't have that problem because the fabric masses so little. Here a balancing error is not likely to cause a problem. Fabric degrades. OTOH, that prompts you to recover periodically. And when you do, you get a look at the inside of the control surface, not a bad thing. To me metalized control surfaces represent a greater risk for catastrophic failure than do fabric-covered control surfaces. The risk is not great but then, the rewards do not seem to be that great either. Given that, it just seems *TO* *ME* that it isn't worth the effort. But on this whole risk thing, what mods really do reduce errors and failures? I see increasing fuel capacity as being a good thing as running out of gas has always been a problem. The risk is that the mod will compromise the structure. The reward is that the pilot is less likely to run out of gas by overextending. There are more "ran out of gas" incidents in the accident stats than "airframe failure in flight" accidents. So everything is risk/reward. And do I think that the metalized control surfaces are bad? Well, knowing both Barry and Doug I suspect they are of high quality.

There are relatively minor reasons not to - such as ribs being made of too thin metal to properly rivet, but the fundamental reason must be the unacceptability of non-aviation designers making unofficial modifications on control surfaces.<<< My -52TW (the first one manufactured by Aerostar) has over 400 hours on it, and no problems with the metal control surfaces...and I fly a lot of acro. However, I do believe my experience has been better (luckier?) than most. I know of several -52W and -52TW owners who have suffered cracks in the rudder and elevators. I have not heard of any cracks in the ailerons. If they do not crack they are better looking and longer lasting than fabric. But if they crack...well, not so good. A roll of the dice? Last year at OSH I talked to Cristian (from Aerostar) about the metal surfaces and he thought Aerostar *might* return to fabric covering. I do not know what their final decision was. I offer all this as just something to consider. Your mileage may vary and never attempt this at home. Fly safe.

George Coy told me that Aerostar had about 25 more new ones that they could build up. Terminus in also had a limited quantity. However, while arranging for my freshly OH'd M-14P to be shipped from Vladimirs place, I mentioned what I'd heard. Vladimir says that the Russian factory is still making them as well as OH. He has 4 in OH now, available in about 6 months if anyone is interested. If anyone needs an engine overhaul, Vlad will arrange another batch, but it won't be as cheap as the last batch.<<<< Fellow Yak drivers, My understanding of this issue is that NOBODY is making some of the parts required to build COMPLETELY NEW STOCK M-14P's. Overhauling them is another issue. The following is from George & Cliff Coy's web site at GESOCO.com; "They {meaning Romania} have a limited supply of some parts. Primarily the carburetors and cam disks. The factory {in Russia} that made the original carburetors is no longer in production. They now make furniture and no one at the factory remembers how to make the carburetors. The tooling was all scrapped as well. We are investigating replacing the Russian pressure carb with a fuel injection system. We are also looking to other sources for the carburetors." Please correct me, George or anyone else, but I believe that after the last of these new carbs, new cam disks, and also new magnetos are gone, nobody will be able to build entirely new and complete M-14P's as we know them now...just versions that partly new and partly overhauled. Or, more likely, they'll also make totally new engines with newly designed fuel injection, electronic mags, etc., etc. With the market's demands, Romania's Motorstar (active M-14P manufacturer), the Russian businesses, and organizations like Bill Blackwell's "Stinky Works" (really cool M-14P stuff) I suspect we will be able to get "new" engines for a while longer. Just not as "stock" as today's. Thank goodness we don't need new Merlins!!
