  1. The parts manual calls out a "la France or equivalent". Not much help there.
  2. The Ryan overhaul instructions allow elongated holes in the elevator connect tube and elevator spars to be drilled out to the next size, not to exceed 1/8 inch larger diameter of the original hole size. Make sure that the new hole is drilled concentric around the original hole center line. Regards, Ron
  3. Skybound is the current certificate holder for these brakes. They have what new stock is available. When you rebuild the master cylinders, make sure that the chain is the correct length or you will not be able to bleed the brakes. I believe the "at rest" gap is 5/32" but check with Jim to verify that. 6910 "A" Buford Hwy Dorazille, GA 30340 1-770-446-6797 Jim Greene, owner Regards, Ron
  4. During inspection, prior to covering my vertical fin, I found a crack that runs completely around the circumference of the rudder post at the landing wire attach hole. Just the leading edge tube and the fabric holding it together. Make sure you take a good look when you have the parts opened up. Fin shows no evidence of prior damage. Ron
  5. Thanks Joel! I have the original paper manuals but hate to run the chance of damaging them in the shop. Regards, Ron
  6. Reviewing the Ryan rigging manual, there is a statement to use SPEC X bolts in the stub wing aft spar attachments and NOT standard AN bolts. The parts manual calls for WS-58-XXX bolts in this area. SPEC bolts can be higher or lower strength or close tolerance bolts. I cannot find a reference in any of my Ryan manuals or the aircraft hardware manuals that I have for the specification for these WS-58 bolts. Does anyone have a print or reference for these bolts? I wonder how many Ryan's are flying with standard AN bolts in this location? Might be worth a look to see what you have installed. You can see the upper bolts from inside the aft cockpit with an inspection mirror and a light. Ron
  7. Although common knowledge seems to suggest that there were no markings on the Ryan PT-22 other than the official paint scheme and buzz numbers, looking through the issues of "Propwash" from Sequioa Field, they actually applied different colors to the front cowls on some aircraft. I have a picture of a Sequioa Field PT-22 that has a yellow cowling. I am assuming my personal aircraft was painted to match this aircraft. When they removed the red ball in the national insignia in early 1942, it appears that they also painted the rudder yellow or in some cases silver, to remove the red stripes. Red was not a healthy color to have on your aircraft in those times. These rudders also had the new dope codes applied. This appears to possibly be a field modification. Not sure why Mike did not paint the national insignia on the bottom of his wings. He might have known that they did something different in the field. Propeller spinners seem to have remained silver as the props were probably changed out on a regular basis and they would not have taken the time to repaint them. Hub caps, propeller spinners and air intake scoops were usually left off to facilitate the daily maintenance requirements. A few later aircraft are all silver with standard star and bar national insignia with no buzz numbers on the aft fuselage. These are few and far between. I see no special paint schemes on the pitot masts. All pictures that I have show them yellow on yellow winged aircraft. In practice, making the pitot mast stand out might not be a bad idea. I have not figured out the reasoning behind the buzz number sequence. Common practice in the AAF was to use the last three numbers of the military serial number, i.e., 550 for 41-15550. With the Ryan's, it is unusual to see an original picture from Sequoia with a "high" buzz number such as "550", although I have a picture from Eagle field with buzz numbers in the three hundreds. I would love to hear from someone with additional information. They might have just started with "1" on the first aircraft assigned to the field and numbered them in sequence. This would appear to be an unusual military practice, but again, I see few high buzz numbers in the issues of "Propwash" that I have. Does anyone have class books from another Ryan contract school that might shed light on paint schemes used there? Regards, Ron N15550, ex N441V
  8. On the internet there was a site that had several copies of the Sequoia AAF yearbook "Propwash" available for viewing. I cannot find it now in any search. Does anyone have a link to this site? Was great to research aircraft paint scheme's. Trying to determine when the red ball was removed from the national insignia and when the "stars and bars" were applied. I know the dates that the orders were issued, but does anyone have an idea when they were normally accomplished? During inspection? When a component, i.e. wing was replaced? I have pictures of all three insignias, but the pictures are not dated. Thanks, Ron
  9. Barry, Service instructions are 19 PSI for the mains. This is for the Shinn wheels with 6.00 X 6, four ply tires. Not sure what the Firestone wheels with 7.00 X 6 low pressure tires require. I doubt if there are any of those flying anymore. One of the experts might chime in with pressures for tires with more than four plys. Regards, Ron
  10. Congratulations Barry! If she flies as good as she looks, I would say that she is a keeper! Ron
  11. JH, just happened to find this info. Hope it helps. Ron
  12. You might try Sensenich in Florida. They rebuild their own brand and could probably steer you towards a shop that can work on the Fahlin if they do not work on them. Just a thought.
  13. I am in need of all four of the brake line clamps that hold the metal brake lines to the landing gear strut tube. Thanks, Ron iflypby@aol.com
  14. I am in the process of rebuilding my Arens tab control and found that someone has been in there before. Now I know why it needs to be rebuilt! If someone could take the time to give me a measurement it would be greatly appreciated. If you would roll the elevator trim to the full nose up position (back) and then measure the difference between the end of the outer housing and the start of the threads on the inner rod back at the trim tab, I can properly attach the inner cables. Or, if someone has a spare Arens tab control that they would be interested in selling? Thanks, Ron
  15. Ken Wilson is a respected historian who has specialized in the Stearman aircraft. I liked his work so much that I had him do the research on my Ryan. He has the machine to cut the original stencil for all the labels and dope codes. He also researched the military history of my aircraft. It also was based at the Visalia-Dinuba School of Aeronautics at Sequoia Field. Ken Wilson idora@wowway.com 1-812-477-7176 Ron
