Date: Thu, 13 Jan 2000 10:50:28 -0600 From: David Domeier Subject: COZY: More Cozy Cruisin' We spent New Year's Eve at our condo about 185 miles from here with 2 other couples, one of which left some pills and personal stuff when we left on Jan 2. I decided I needed to patrol the area between here and there with the Cozy yesterday, so why not drop in and retrieve the pills for the lady. It was a very pretty day except the winds were a bit weird. Surface wind was Northeast at 5 knots but at 8500' on a course of 250° there was a significant headwind. A ground speed of 110 was most unacceptable, so I let down to a1000' AGL and recovered 35 knots but it was quite bumpy. The Navaid autopilot coupled to the GPS course did not seem to mind the rough air. It just kept on navigating without much ado. I am most impressed with performance of this low priced autopilot. The S-Tech altitude hold also did very well in the rough air. These aids are most helpful in doing a good job of patrolling and noticing stuff that needs noticing - like good landing spots should one be necessary. Landing at the little airport was uneventful. Total time from engine start to shut down - 56 minutes. This place had a free courtesy car the last time I was there but some jerk must have screwed up the deal. The attendant said the car was no more because of an uproar. I had to take a cab at a cost of $22 round trip. It was an old bear up Ford van, the only cab in the area. I noticed many junk cars parked at this airport, obviously owned by pilots who fly in as did I. Many of them were in better shape than the taxi. I was looking forward to the trip back to St. Louis and pleased to see 211 knots on the ground speed meter at 7500'. (242 mph for you marketing types) I had set up 66% power on fuel flow of 8.7 gph and the machine yields 160 knots TAS at that power setting. About 35 miles out the altitude hold was tripped off and a couple shots of nose down Alex Strong trim started the descent. Speed picked up to 232 knots for a time. Tower approved a straight in approach and I was parked the hangar with 36 minutes logged from engine start to shut down. Not too shabby for a hand built, homemade flying machine. As I've said before, I remain very impressed with the Cozy MKIV. It is a pleasure to launch every time. Hang in there builders and keep mixin' that glue. It's worth it. dd From: "Clark Canedy" Subject: COZY: Chapter corrections Date: Wed, 26 Jan 2000 20:46:05 -0800 I want to thank Larry Capps for building the Cozy corrections by chapter. I would also like to remind the group, especially the new builders, that at least 80% (Estimated) of the corrections have already been made to the TAN colored plans. Because the corrections don't have the NEWSLETTER NUMBER to go with it, its possible that a TAN plans owner could duplicate a change. For example: the chapter 4 change to move the cluster of three bolts on the fire wall up 2" is a problem for the TAN plans owners because one can not tell if that correction has been made by looking at the drawings. Text type changes are easy to reconcile because the TAN plans will reflect the change. I notice that plans numbers builders in the 600, 700, and 800 range are making most of the building inquiries that would indicate that they have TAN plans. For what its worth.....check the news letters that affect the plans version that you have. Date: Thu, 03 Feb 2000 18:57:07 -0500 From: "Marc J.

I don't think the same results will >happen in a Beech Sport or Tomahawk, too inefficient. >A Bonanza or a 206 have lots of weight, you won't get the same results >either. It is possible to calculate exactly what bank angle and speed to use for a 180 degree return to runway on an engine failure, and it's dependent upon a stack of parameters, most of which will be hard to obtain. However, for those that want to explore this more, refer to John T. Lowry's book "Performance of Light Aircraft" (available from http://www.fatbrain.com for about $56). Using his techniques, you can obtain the parameters you need and calculate necessary altitudes and bank angles for a given airplane under given conditions. Rather than speculate about techniques taught by CFI's who may or may not really understand the physics behind flight, better to understand what's important, do some calculations for YOUR aircraft under YOUR conditions, and then practice the 180's while climbing at Vx or Vy at 3000 ft., and then see how much altitude you lose getting back to the imaginary runway. The general calculations show that the bank angle should be just slightly over 45 degrees and the speed should be about 5 kts. over the stall speed at the 45 degree bank. For the example of the Cessna 172 at 2400 lb., 10 deg. flaps, 50 F temp, 3000 ft. runway, climbing at Vx, wind 12 kts., etc., with an failure at 500 ft., the optimum bank angle is 45.5 degrees, the optimum speed is 58 Kts, and you DON'T make it back to the runway - you're short by 1100 ft, even if you do everything perfectly. There's a lot of math in this book, but it's excellent, and really explains how aircraft work. Non-technical types can ignore the math, read the text, get a good qualitative understanding of airplanes, and use his "bootstrap method" to determine complete aircraft characteristics by taking a few simple measurements. I highly recommend it. -- Marc J. Zeitlin mailto:marc_zeitlin@alum.mit.edu http://www.ultranet.com/~marcz/ Date: Mon, 15 May 2000 21:44:50 -0500 From: David Domeier Subject: COZY: Re-certification.... Two FAA guys from the local FSDO came out an re-certified my Cozy today. The new operating limitation concerning major changes will be a part of airworthiness certificate. It will cause the airplane to revert to phase one test status for 5 hours and require a log book entry. It was explained that the operating limitations can not be changed without invalidating the original certificate. So a new certificate has to be issued.....that is the local ruling and probably applies everywhere. The event was was not simply a paper exercise. They did inspect the airplane and all the previous paper. It lasted about 1:30 hours. Another issue is insurance. I called AVEMCO today to get a reading on "exclusions" in my policy. Specifically, the policy excluded hull coverage after major changes for 10 hours and 10 take offs and landings. That applies to loss directly caused by the major change. If the change was a prop and the engine fails, the airplane is probably still insured. Liability insurance is not affected. That seems to be the case even if the airplane was originally covered from first flight with an EAA tech advisor involved. dd Date: Tue, 20 Jun 2000 21:53:32 -0400 From: Jim Sower Subject: Re: COZY: Repairs to canard airplanes Marc, I oversimplified my remarks. Yes I know I am ALLOWED to do the repairs (so long as I get them signed off by an A&P - which is very easy). The thing is that I'm quite certain (and Ken Miller and all the really authoritative folks I know agree) that REPLACING F-22 and surrounding structure on a painted airplane with all the instruments and hardware installed is lots more difficult than CONSTRUCTING that part of the fuselage TUB. I have NO help within range and NO canard builders within 80-100mi. I'm a neophyte and the experts agree that building my Cozy fuselage will be what it takes to acquire the skills to FIX the EZ. I'm pretty well convinced that I'll have to do this the hard way since I'm all by my very own lonesome here. That's the heartbreak part. Last year, I spent from Apr 10 till labor day doing the annual and all the upgrades and engine work. Now I get to miss another flying season. Thanks for your concern.

From: "Jonathan Lones" Subject: COZY: Re: N Numbers Date: Thu, 16 Nov 2000 23:04:46 EST Greetings, I work in new aircraft sales and have reserved several N numbers in the past year. The best place to start your search is the aforementioned website www.landings.com. There you can search both current and reserved registrations, but keep in mind the information is at least a month old. Once you've narrowed it down to a few choices give our friends in Oklahoma City a call at (405) 954-4206. They can tell you which numbers are available. As Mr. Slade noted, they are capable of "wildcard" searches. Just tell them what letter or number combinations you're interested in and they'll read you a list of choices. If you're lucky you may even find a one or two-digit registration such as N1BK or N77BK. Good luck as they are scarce! A few rules to remember: registrations cannot begin with 0 (zero), contain the letters O or I (easy to confuse with zero and one), can consist of up to five characters, the last two of which can be letters, and N1 through N100 are reserved for government use. By the way, N1 is a Gulfstream IV! Hope this helps.

Your local building supply has two-inch round aluminum vents with louvers and a built-in window screen. That's what I use. I trimmed the hole so the vents just push in...no screws. Also, I made two little fiberglass ducts to let air pass around the sides of the rear seat cushion and into the centersection spar.

This provides two functions:

1) a drain to remove any water that may enter the cabin through leaks, and

2) extract the air close to my feet. In removing the air in this manner it
forces the warm air to pass by my feet. Everyone complains that their feet
get cold but the rest of the body is warm.

There are exit holes from the heat duct in the rear pax compartment and I
have installed an overhead heat duct so that warm air will flow forwards,
over the heads of the pilots thus keeping the canopy clear of condensation.

It always struck me as odd that the air should enter the cabin at the rear,
be sent forward in a tube, then extracted at the rear again. The logical
choice would be to bring in warm air at the back and exit the air at the
front.

For Those of you with high-numbered plans (mine's 899) or those who are just getting started, I got a decent enough deal on G10/FR-4 for the LG hardpoints from Abbott Plastics in IL. For a 12"x12"x1/4" piece, they charged me $10. They also charged me IL sales tax ($0.63) and a shipping charge (UPS ground) of $10.58. Nonetheless, I was happy with their friendly service and would recommend them. I figured it would cost me that much to make it with only 22 plies, as per plan. http://www.abbottplastics.com My thanks to whomever mentioned the carbide grit blade in a jigsaw to cut it. I picked up one at Menard's for $3.50. It (still) cuts the stuff very well. (side note.. interesting that all of the Bosch jigsaw blades are made in one place, but the carbide grit blade is made elsewhere...in the UK, same as Permagrit.. coincidence?) I also have a question to the group.. Instead of the 1/4"x1"x1" Alum. inserts in the firewall, is there a reason why I wouldn't want to use the G10 instead? Is it for heat resistance? From a corrosion resistance standpoint, it seems much more desirable. Does anyone have numbers on the crush strength? I guess I'm just curious why not... I'd greatly appreciate any info. How about the "EM-2" aluminum plates on the fwd side of the firewall?

Lynn Cunningham's business (http://www.cunninghamcovers.com/) is located at my field and I have seen plenty of his covers (which are well done), so I had him make me one. When we couldn't make OSH, he asked if he could take mine along as an example and I agreed. I also put up some pictures at http://home1.gte.net/res08ahw/Cover/Cover.htm to let you folks know. I figured if someone was in the market at OSH and could try it to see if it fit, it would better equip them to make a decision. After work today I went to the airport to see what was up for Kevin. His cover was completed weeks ago and was sitting on the table; Lynn was waiting to get a couple of strap measurements off of mine before sending it Kevin's way. Lynn has plenty of work to keep him busy, when I dropped by today he had 3 other people sewing for him. He's a skilled, honest person that keeps plenty busy. It sounds like Howard has a good source as well. Of course, if you can find someone local to sew cover for your plane, you know it's going to fit. Like Howard, I have no financial tie to any of this. _________________________________________ Eric Westland Cozy Mark IV N325PD http://home1.gte.net/res08ahw/index.htm (new address) ----- Original Message ----- From: "Ed Richards" To: "Cozy Builders List" Sent: Tuesday, December 19, 2000 6:12 PM Subject: COZY: Re: Aircraft Covers > Kevin, > You might try Eric Westland.
