Subject: Re: Pietenpol-List: EAA's new "Sport Pilot" magazineDoc,Thanks for this update. The Sport Aviation publication which comes with EAA membership is an excellent publication however it has little to hold my interest. I called EAA weeks back and asked if they would send me the new SportPilot magazine in lieu of Sport Aviation. I was pleased that the answer was yes. I'm looking forward to that April issue. ThanksCorky in La waiting for the Sport Pilot to pass also.________________________________________________________________________________Date: Wed, 24 Mar 2004 15:22:16 -0500

the Fisher line of aircraft use a plywood spar with sitka spruce caps. Mydad has them on his Fisher Celebrity. Good and strong. I don't have actualdimensions but I'm going over tohis hour on Thursday and can get them ifyou'd like.DJ----- Original Message -----

Subject: Re: Pietenpol-List: Web sparDick:I built an Avid Flyer about 13 years ago. It had plywood ribs with a very wide capstrip. The capstrips were wide enough that Avid did not advise or recommend rib stitching. In fact, the factory Avid Speedwing could zip along at130 MPH and I personally did aerobatics in one. There has never been a situation offabric pulling off of a glue-down capstrip on an Avid. The pilots who worked at Avid flew the devil out of their factory airplanes, on many occasions from Idaho to Sun & Fun.I loaned my Avid to a guy when I was away on a business trip. He stalled it out at about 300 feet and the resulting crash destroyed my airplane (did not injure the pilot). The plywood ribs held up very well. Much to my amazement, Avid spars are made of aluminum tube (both front and rear spars.) The plywood ribis bonded to the aluminum spar with a two part 3M epoxy. Not a single joint failed in the crash but chromoly tubing on the fuselage pulled apart at a couple of weld points and in the middle of tube where no weld was present. WhenI took the wreck home to begin salvaging what I could, I had great difficulty intearing the fabric from the capstrips. If memory serves me correct, the capstrips were about 3/4 inch wide.I had thought about plywood ribs last night and today my goal was to track down a friend of mine who was the GM at Avid to see if I could find out who madetheir ribs. I like the idea of glued-on fabric without rib stitching (despite the fact that there are nonbelievers in this method) because the end result is a very attractive wing, not to mention saving some labor. If I locate someone who can build such a plywood rib, I'll contact you. In the meantime, I'm going to also try and locate Avid's former R&D guy. A terrificpilot and A&P named Jim Raider. (I may have spelled his last name wrong.) Jim is one of those guys who in VERY analytical and wouldn't incorporate something into his project unless it was a proven process. I think Jim built anAvid Magnum with a 160HP Lycoming using plywood ribs and no rib stitching.Sterling BrooksKnot-2-Shabby Airport & Texas Longhorn Cattle Ranch5TA6 (San Antonio Sectional)________________________________________________________________________________
