    Subject: Yak-52 (and CJ-6 etc) Airworthiness
    --> Yak-List message posted by: "Richard Goode" <richard.goode@russianaeros.com> To correct Jerry Painter, I don't believe Mark Jefferies said that you could operate Yak-52/CJ-6 in the US on a foreign register. The reason for this is simple - they have restricted Certificates of Airworthiness - which you would call 'Experimental.' Such certificates are valid only in the country of issue. They can be made valid in another country, but only with specific overflight permission from the CAA/FAA in that country, which they might do for a short period, but not long-term. Conversely, aircraft such as the Yak-18T, An2 and Su-29 do have Normal Category Type-Certificates, and therefore can fly on their foreign register in the US, or indeed anywhere else.

    Subject: Re: Airworthiness Certification
    --> Yak-List message posted by: "AEROSTAR" <aerostar@aerostar.ro> Dear friends , We update here information we have in relation with a potential type certification for YAK 52 aircraft , considering the discussions issued this period in this forum . The standard YAK 52 aircraft is designed by OKB Yakovlev , in Russia . The project has a certification in Russia , this certification making possible to use the aircraft by DOSAAF , for the local training . The standard design used for YAK 52 was AP 23 , a very well & safe set of requirements , this standard being similar with the western standard FAR 23 . In this respect , the aircraft design is considered safe and perform . Technically , to can obtain a Type Certification for YAK 52 an to be valid for FAA , the aircraft must to be designed to respect FAR 23 standard , it being accepted in US . To do this , the aircraft needs to be redesigned in some areas , where these two standards ( AP 23 and FAR 23 ) are different . This design work will request an investment . Another investment is to build minimum a stress airframe and an aircraft prototype , in order to develop a program of tests defined by these FAR 23 standards . The design , the calculations and the results of all tests must be inspected by a civilian authority and accepted as respecting the requirements of the standards . In our case , the aircraft must repeat the entire program for certification respecting FAR 23 requirements . This full process takes time and money , making necessary an investment . And it is not small , many companies spending millions dollars to certify an equivalent aircraft . This process can be supervised by FAA itself or by a local aviation authority in other country and FAA to agree this . To do this , is necessary to exist a Bilateral Agreement between the countries involved , in our case USA and Russia / Romania. This agreement needs to cover the Light Aircraft domain , section where YAK 52 can be included . USA and Romania in this moment have a Bilateral Agreement signed together but it is not cover yet the Light Aircraft section , in our case being still not valid for YAK 52 . It could be extended , if the two countries consider to be in their interests . If exists a strong interest or the marketing researches define a good potential for sales , these processes could be started , if an investment is to be available . I consider an investment for few millions dollars . For sure , a Type Certified YAK 52 aircraft will cost significant more compared with the present price , to can recuperate this potential investment . For sure , being type certified , YAK 52 will have an extended market , the aircraft being legal available to be used by the flying schools , companies Experimental category . If almost 100 type certified aircraft could be worldwide sold with around 250 000 $ each , maybe a type certification can be considered . The situation for today allow YAK 52 to be used as Experimental aircraft , as an " Ex - military " aircraft . The new models we produce now are Experimental also , registered as " Ex - military " aircraft ( YAK 52 W ) or " For Exhibition " ( YAK 52 TW ) . You cannot make money with the aircraft with these registrations , but you can use the aircraft to enjoy you , for your own personal use . Europe and Australia accept the aircraft with registrations similar with the Experimental registration in US . The aircraft has a good real value , with good performances , with a reasonable price and very low operational cost , many countries wishing to have it in their inventory . Some countries are using the aircraft for their national airforces , the training system being considered very acceptable for them using YAK 52 aircraft . Sincerely , Cristian Dragoi + 40 721 241 306 ( cell ) + 40 234 575 070 ext. 1402 ( tel ) + 40 234 572 445 ( fax ) aerostar@aerostar.ro www.aerostar.ro

From my perspective though, I personally do not know of anyone who would be willing to give up the Experimental certification on their aircraft in exchange for a Standard Airworthiness Certificate in the Normal category.

I have the kits and ordered a complete one as a spare in case I can't get one open. The old ones work fine but I have no history on their last overhaul. Plan on doing the uplocks too. Any comments on techniques would be nice. Ron Wasson

The Tunica Air Races are looking for acts. The dates are June 2-5. Show of hands...how many would be interested in doing mass flyovers for the show if we can get them to pay for fuel/oil/smoke oil for the show. We may have to stage from Memphis to the act though, as ramp space is extremely short... not sure of many details on this one yet...but if you are interested drop me a line!

    Subject: Paddle Blade Setting
    --> Yak-List message posted by: "cpayne@joimail.com" <cpayne@joimail.com> I am in the process of doing just a bit of testing on prop blade angle setting vs performance and I have improved my adjustment technique a bit. In general I have followed the written procedure as published by Jill Gernetzke but added a refinement: AFTER setting blade angles using the smart level, follow up with a square-sided laser level that can project a line. Set the level chordwise against the back of Blade 1 in the same place that you put the Smart Level (8" from the tip). Place a shiny straight edge on the hanger floor so that it's edge is lit up with the laser line lengthwise. Rotate Blade 2 to the same level position and lay up the laser level the same reference spot as Blade 1. If the projected line does NOT line up with the edge of the staight edge, carefully reposition the blade angle to the same spot. As always, recheck your work after tightening but before cotter pinning. Makes for Smoooth running! My goal here is to *find* the sweet spot between the blade angles and governor setting so that 2900 RPM can be achieved at the coarsest blade angle setting that will allow it. CJ's with the M-14P/paddle blade need not be constrained to the same setting as the Yak; but it will be within the same general range. A final flight test is made for each setting at climb and top end speed with levers full forward. Craig Payne

I assume yours are faster. Wait a minute, Aren't you running the M14 (360 Hp?) instead of a HS-6A? Our secret labs are working around the clock to reverse engineer the pics of your speed mods we took at waycross....Thought we were being pretty crafty till you walked up and asked us "what do you want to know?" Been meaning to ask, Speed mods are usually not cumulative, what mods have given the most noticable performance improvement?

    --> Yak-List message posted by: cjpilot710@aol.com Another beautiful day here in Florida. I just finished rebuilding the cooling cowl vanes (Chinese call them "Fish Scales"). This was quite a job. I've spent long days in the hangar this week. The two aluminum ring castings had worn though in a number of places; to the point that a number of the vanes were just flopping around. I disassemble the entire unit, and took the castings to a local weld shop were they filled up the all holes and worn out sections. I than sat down with a file and dressed them back to shape. Next I made drilling jigs to re drill the all the holes. Wall-la!, she's back on the machine and works just fine. As simple as these mechanisms are you can screw them up. Position of the holes are very important. It is possible to put them back together, up side down and backward! All the parts will fit beautifully, but she won't work worth a *&$%. Yes I did do just that. Since there are 28 vanes, it means undoing your mistakes 28 times! Maybe someone could tell me how much a replacement system cost. Than I can either feel proud of myself or wonder why I put myself though so much work. Did I mention that it was a beautiful day here? :) Jim "Pappy" Goolsby

I have not been able to find a new set for 2 years now, so you just saved yourself 1250 at the minimum! Not a bad days pay even for a big iron driver!! You should have asked me about the backwards thing, I have experience in that area also. What did you use for the long pivot bolts?

It is VERY crude right now but is up and running and yours truly is enrolled in night school to try to learn the fine art of web design, ya I know, old dog, new tricks, it's doubtful at best. I'll update the list and refine the site as I bumble my way through the class. Wish me luck, I'll need it. Geeze, I'm the new kid again, back is school after 40 years! Always Yakin, Doug Sapp -----Original Message----- From: owner-yak-list-server@matronics.com [mailto:owner-yak-list-server@matronics.com]On Behalf Of cjpilot710@aol.com Subject: Yak-List: "Fish Scales" rebuilt. --> Yak-List message posted by: cjpilot710@aol.com Another beautiful day here in Florida. I just finished rebuilding the cooling cowl vanes (Chinese call them "Fish Scales"). This was quite a job. I've spent long days in the hangar this week. The two aluminum ring castings had worn though in a number of places; to the point that a number of the vanes were just flopping around. I disassemble the entire unit, and took the castings to a local weld shop were they filled up the all holes and worn out sections. I than sat down with a file and dressed them back to shape. Next I made drilling jigs to re drill the all the holes. Wall-la!, she's back on the machine and works just fine. As simple as these mechanisms are you can screw them up. Position of the holes are very important. It is possible to put them back together, up side down and backward! All the parts will fit beautifully, but she won't work worth a *&$%. Yes I did do just that. Since there are 28 vanes, it means undoing your mistakes 28 times! Maybe someone could tell me how much a replacement system cost. Than I can either feel proud of myself or wonder why I put myself though so much work. Did I mention that it was a beautiful day here? :) Jim "Pappy" Goolsby

    --> Yak-List message posted by: "cpayne@joimail.com" <cpayne@joimail.com> Robert, The biggest "secret" is to get the gear doors to fit well. You should be able to just slip your thumbnail in the gap; I use thin rubber strips on the geardoors to prevent chafing. An Amazing amount of speed is lost from "droopy doors". It also helps to (carefully) bend those thingys on the rudder and ailerons so that the airplane flys straight...The biggest benefit is a good fuel burn at economy settings. In formation with Yaks, I burn 9.2gph to the Yak's 15gph. Start by first leveling the airplane side to side and then getting the Slip/Skid balls centered before flight testing for which tabs to bend. BTW, I'm missing pages 3 & 4 and 202 & 220 of section 073.10.03 of the M-14P engine manual. The Carb section. Anyone have them? Craig Payne

    --> Yak-List message posted by: "A. Dennis Savarese" <DSAVARESE@ELMORE.RR.COM> Craig, I have it and will put it together and email it to you. You said you were missing pages 202 & 220? I've never seen page 220. Are you talking about the task cards?
