Andy has had it since May but, despite chasing, has yet to come back with the formal approval. The same applies to the revised mods 75 & 76. I think it would be helpful if I added your notes to the Mod 71 documentation. If you are happy with this I will send you a revised draft in a few day. When you are happy I will pass to LAA for formal approval. Out of interest, why was the forward, top, inboard corner of the stbd foot well removed in the attached picture?

I am about to install the Dynon servos but lacking your update to the Mod, I compared the Dynon SV32 to the TruTrak B servo and having concluded that they are almost identical I came up with the attached mounting scheme. I would appreciate your comments and a copy of the Mod 75 and Mod 76 revisions. I designed and fabricated all of the mounting hardware to suit the Dynon servo since the factory did not offer a Mod - if you'd like I will send you the detailed drawings.

At Europa's request (David Goddard said he was too busy) I had it approved by the LAA. I have passed the factory the master copy but as yet they have not got round to putting it up. Mod 77 (Push rod rudder drive) and Mod 78 (Glider wing fix) have gone up recently but the revised versions of 75 and 76 (which include the Dynon servos) are not up yet. The opening for the tube to pass into the spring hook is a bit tight. It is perfectly OK to take off the inside corner to allow the tube in as Jeff B suggested.

In the May 2006 version of the Mod it looks like the openings face aft but in the 2011 version the opening is forward. I elected to use the latest version for guidance. The Landing Gear Frame in my kit has several additional members so there is not much room for the upper hooks to move in either direction - they are trapped between two narrowly spaced tubes. In my case your other suggestions about getting the springs in place don't apply since I am doing Mod 71 right after Mod 72, so the engine is on the floor and not in the way. I also eliminated most of the hassle getting the springs in place by removing the tie wires and the four bolts on the pillow blocks that are the pivot points for the nose gear arm. With the leg free to move a bit (still restrained by the safety cable) I could get the lower hooks in place with minimum fuss. Of course, with the engine on the floor that leaves me to contemplate how to load the springs with sufficient force to remove the spacers.

Note that I install the springs with the openning forward. Please note the left and right hand wind requires you to place the springs so that they do not rub against the center tube. The springs can be installed facing aft but the last snap in is a bit difficult unless the entire wheel well is open or you are very strong. Forgive me that I do not have my tech article on how to install the springs any longer as folks were just not having problems and it went to archive somewhere. Bob Borger and Gary Leinberger may have photo's of us doing theirs if you ask.. Please round over the spring as per the drawing to make snapping the spring over the top tube less painful. You may do the lower part as well. One indispensible tool is a piece of stainless cable with handles on both ends to snap the spring up and over the top. I have one of the guys standing on the wheel well and pull it up to snap in the spring over the upper tube. Then he bounces on the front until the 5/16 and 1/4 inch bolts fall out. The other nice to have tool is a set of threaded rods with a couple of curved ends to help hold the gear up while I install, but rope or a strap works also...I just like steel to protect me from a rope brake or strap slip. It takes me with two helpers (for added weight), about 45 minutes to install the springs. Description: cid:image004.jpg@01CC6618.7F05B330 Description: cid:image005.jpg@01CC6618.7F05B330 Small pieces of stainless between the spring and frame glued in or just set in sealant will keep the spring from scratching up your frame and rusting later on. Even with an engine on you can see that putting a cable through the hook on the spring and pulling from above is an easy safe method to snap the spring in. Technique: I normally put the engine on to add weight when I am doing this operation alone. I put a strap around the gearbox and nose gear leg to pull the spring a bit to get the bolts to fall out then repeat. Please use safety precautions so as not to injure yourself when stretching and installing the springs and you will find it is an easy install.

The diameter of the Landing Gear Frame is 1.55 inch (39.4 mm) and the opening in the spring that must hook onto it is 1.35 inch (34.3 mm). This seems to allow for either of two solutions, neither one particularly elegant. 1) use brute force to deform the hook in the spring, 2) cut off some of the end of the hook.

I do not get into the loop on the finals of these mods as I am not the only person putting in changes. I would like to see the final issues sent to Andy if it is not too much trouble. Different folks are responsible for different mods so I am not privy to all the final touches until the Gods at the LAA pass judgment I'm afraid I just am too much of a maverick and "git 'er done", rather than mother may I. The clearance was necessary for a Jason Parker Fuel injected Rotax and a specialized frame for a 50 amp alternator that belt drives off the rear of the crank shaft and the alternator bracket didn't quite fit... We measured three times and it just was a little too tight, so I needed another 1/2 inch. Those little compromises we make for clearances. By putting the alternator off a belt drive, the maintenance and access in the engine compartment is superb, but the frame is a proprietary frame, similar to the Rotax frame, but modified for clearances for the belt...

If you don't have the engine, make friends with three 200 lb. agile guys to spring things into action. I am surprised that you don't leave the gear leg attached final as it is quite easy to snap the spring into place even working alone. As Bob Borger indicated in his email it takes a bit of rounding of the spring end, and a bit of a pull to get them in. One thing that was not forwarded though is I use a few 5/16 inch bolts to help lengthen the spring. Hopefully Bob's photo album shows that we took the time to prep and make sure the spring was dead straight. I have an unfair advantage that I have done many of these and frankly miss what I consider is obvious, which is not. Apologies for leaving that info out.
