October '98 Volume 98.10


This Month

- Keith Williams, President

The October meeting will be on Saturday, Oct 3, at Tom and Marilyn Olson's home: 4170 Riverview Road, CR. The Chapter will furnish hot dogs and buns, coffee, and soft drinks. Each family can bring either a salad or dessert. We'll have a bonfire, so you might want to bring some roasting sticks and marshmallows! Bring lawn chairs and those neat little picnic tables if you have one. Come "whenever"; plan to eat at 5:30. If you have questions, please call Tom at 393-5531. (It won't do any good to call your President, as I will be out of town.)

Flight Testing

Flight testing can be scary, a real drag, or a lot of fun. Tom Olson told

about his flight test program and it was clear that he was enjoying every

minute of it! He didn't even complain about pullin' up to the pumps and

putting $65-worth of avgas in the tanks.

Tom was following, generally, the FAA guidelines for testing of amateur built airplanes. He had also gotten a aircraft flight manual for an RV-4 (I think) off the internet and was modifying it so it would apply to his RV-6A. Tom has gathered data and drawn nice charts to include in the manual. For example, he knows that his glide ratio is 10:1 or better, that he has to slow way down to get the prop to stop, and he has to push the nose down and get up to about 160 MPH before it will turn over again!

The RV-6 builders, and probably many others, must be prolific interneters; Tom sometimes get 60 messages a day from other builders.

One couldn't help but be impressed by the rigor with which Tom did his flight testing. He's now a Technical Advisor and could do a good job of advising regarding flight testing!

Flying Start

EAA's Flying Start program was described briefly. National requests that each chapter do at least one program this year. I recommended that we do become involved in this program, and asked for anyone who might be interested in coordinating Flying Start programs to contact me.

Tom Olson, Terry Scherman, and Keith Williams attended chapter workshops and a leadership meeting at AirVenture '98. Some items from those meetings:

- Chapters with a "home" (hangar or fixed meeting place which they "own" on an airport seem to be much more successful than those which don't. A chapter doesn't have to be huge to have such a home; chapters smaller than ours have their own places.

- Chapters should be politically connected to the local airport commissions. If they don't have a member on the commission, they should at least have a "watchdog" who attends the meetings regularly. Chapters politically involved can often influence the decisions. Those who have watchdogs can at least not be surprised and can provide input to the commission on various subjects of interest.

While it may be impossible to become a strong voice in the CR airport commission, it would be good to be aware of what's going on there. Anyone interested? Marion would seem to offer a much better opportunity for participation. Anyone especially interested in keeping track of what's going on there on a more-or-less regular basis?

- The establishment and maintenance of tax-exempt status was stressed often. The key here is that foundations, companies, and individuals can then make contributions to the chapter and deduct the contribution. This opens the door to exciting possibilities for financial growth. (It doesn't take a rocket scientist to see how this relates to having a home of our own!)

- Chapters should spend some time (it takes a few hours for a few meetings)

reviewing where they want the chapter to be in the future, and writing a mission statement. This can really help guide the chapter and is very helpful in attracting support for programs which provide public benefit (educational programs for youth, for example). It isn't a lot of fun and not all members need participate. However, it was suggested that during the winter months 10 to 20 members get together and consider our future and our mission.


Greg Zimmerman commented on the joys and benefits of volunteering during AirVenture and encouraged everyone to do it next year.

I commented that Ron White, Steve Ciha, and Tom Olson had flown up before the show and put in some time. He apologized for not having gotten an "official" chapter work party together, but that was just one of those things which didn't get done. He called for someone to consider becoming the chapter's Volunteer Coordinator. (See separate article.)

New Members

Bernie Hayes and Randy Hartman have joined Chapter 33 since our last meeting. These are the partners in the Grand Champion Plans-built airplane at AirVenture '98!


If the Chapter "sponsors" new members to national EAA, we get a $10 rebate. If you know someone who wants to join, get a form from me and we'll get our $10! If that's too much hassle, just have them join and write on whatever form they have, "Sponsored by Ch 33".

Next Month

- Keith Williams, President

The November meeting will be on the regular night, Friday, November 6, at the Hills Bank in North Liberty. Meeting will begin at 7:30. The entire program is not yet set, but one important part of it will be election of officers to guide the chapter in the coming year.

Chapter Business

- Keith Williams, President


Election of officers for Chapter 33 will be held at the November meeting. In

preparation, a nominating committee consisting of Tom Olson, Max Dirks, and Greg Downes (Greg Zimmerman an alternate for Downes, if he can not accept) was appointed. If you are interested in a leadership position or have suggestions regarding chapter leadership, please discuss it with someone on the nominating committee.

Completion Certificates

On behalf of the EAA and Chapter 33, the President presented framed completion certificates to Tom Olson, RV-6A, and Bernie Hayes and Randy Hartman, Long EZ.

Officer's Column

- Terry Scherman

As I write this column I think back to the day that I first flew my Long-EZ. The year was 1988 just a little over 10 years ago. I did not have a lot of hours in any aircraft at that time. My log shows that I had around 180 hours, 55 hours of pilot in command in spam cans along with an additional 125 hours in my KR-2.

Many things have happened since that time. I have not had a total engine failure in my Long-EZ, but I have had a crankshaft failure in my KR-2. This crankshaft failure occurred shortly before I flew my Long-EZ for the first time. I was lucky and managed to land it at McBride Airport dead stick.

Over these past 10 years, I now have over 1200 hours logged on my Long-EZ. I have had a number of close calls related to engine failures.

The major problem that I have experienced over the years and undoubtedly the biggest problem I have had with my Long-EZ has been oil cooler failures. To date I have had 5 oil cooler failures. Non of these failures occurred in my 40-hour flight test period. In fact the first one occurred after I had over 200 hours on the aircraft and when it happened I was not aware of it. I had noticed that the oil pressure had dropped off about 15 PSI and wondered about it, but did not think too much about it at that time. Fortunately I was landing at Iowa City when it occurred and only became aware of the problem after I had landed. That time I was really lucky because if I had flown for another 15 minutes, I would not have had any oil left and would have had to make a forced landing.

The last time I had a cooler failure, it occurred about 2 years ago. I had been flying with Ron White and had dropped a little way behind him.

In catching up with him I again noticed that the oil pressure had dropped off as it had done every time that I had broken a cooler. This oil cooler failure scared me more than any of the others. We were only 10 miles from Iowa City and 20 mile from Cedar Rapids. I had initially headed for Cedar Rapids but the oil pressure had dropped very rapidly and kept dropping, so I changed my mind and headed for the Iowa City airport. The pressure had never dropped below 50 PSI before but this time it was down to 35 PSI when I entered the pattern at Iowa City.

I think I have since solved the oil cooler problems, which I believe is being caused by a harmonic problem between the engine, prop and oil cooler. I am sharing this with you because I believe that if you fly, sooner or later you will have some kind of an engine failure. Since I have experienced these problems I fly much more conservatively than I used to. Altitude is always your friend and not having any is definitely not a good idea. My Long-EZ has a very good glide ratio but even its good glide ratio will not do me much good if I'm too low.

Probably the most surprising thing to me about all of this, is the fact that I apparently discovered all of the oil cooler failures within a couple of minutes after they occurred. If you would have asked me if I check my gauges that often I would have told you NO. Apparently I have better habits than I thought that I had. This is another reason that you should pay attention to what you airplane is telling you. Any change in sounds, engine gauge readings or flight characteristics should be made note of and checked out.

I hope this article does not scare you out of flying. I still believe that flying has very acceptable risks associated with it. I find that it is a great way to relieve tension after a hard days work and I would not give it up for anything.

First Flight

Paul Jones has the first, second, and third flights completed successfully on his Solitaire, a Rutan-designed self-launching sailplane. He flies out of Belle Plaine. Paul reported that Marv Hoppenworth and Ron White were helpful in completing this ten-year project.

Time Flown Off

Tom Olson completed his 40-hour test period on his RV-6A and celebrated by flying it to the DBQ flight breakfast.

Volunteer Coordinator

Steve Ciha has volunteered to be the Volunteer Coordinator for our Chapter. In this role, Steve will try to be aware of needs for volunteers at OSH or other aviation-related venues and, in turn, make us aware of these opportunities to participate. His job and his intent is not to be an arm-twister but to make it easy for you to know of the opportunity and to participate. Do you realize that four two-place airplanes could put eight Chapter 33 volunteers on the ground in Oshkosh in less than two hours? That's powerful! If you are even a little bit interested in volunteering, talk to Steve and let him know of your interest. He'll keep his eyes open for a perfect opportunity just for you!

Grand Champion Judging

The Chapter is pleased to have among its members the AirVenture '98 Grand Champion Plans-built builders: Bernie Hayes and Randy Hartman. While Bernie was off in Israel serving The Radio Company, Randy "had" to take their beautiful Long EZ to OSH.

Randy described the emotional roller coaster he's been on, going from the pinnacle of home-building success (Grand Champion) to the depth of despair as he climbed out of the same airplane following a not-quite-on-the-airport landing due to a failed engine. Fortunately, his only physical injuries were slight cuts on his face; his passenger had none. At last report, the airplane is back in CR and is quite repairable.

The "judge me" sticker had over a dozen signatures, a pretty good clue that the plane was considered something special. The toughest part was waiting for all the other awards to be given out, as the Grand Champion, Plans-built, is the last award given!

Randy commented that his goal from day one, which was 15 years ago, was to build a Grand Champion plane. And he and Bernie accomplished the goal!

Congratulations, guys!

GlaStar Fledging in Monticello

I read in the "Tipton Conservative" this week that there is a GlaStar under construction at the Monticello Airport. It is being built by Mr. Robert Kelley of Lisbon. Mr. Kelley is a W.W.II veteran pilot. He hasn't flown in 30 years, but has decided to take it up again. His GlaStar is located in Monticello. He started building it in 1995 and has been working 8 hours a day since then. He now has 1,600 hours and $57,000 invested in his project.
I spoke with Mr. Kelley this evening and he told me that he is nearly ready to do his taxi tests and hopes to fly in November. I twisted his arm a little bit about joining our Chapter. He said he would be willing to show off his airplane at a meeting when it is finished or have us come visit him.

Mr. Kelley tells me that Marv (H is for Have been there) Hoppenworth has visited his project a few times and has been a help to him.

He sounds like the sort of person we want in our Chapter. Let's make him feel welcome. I asked him if he knew Roger Smith or Max Dirks, since he is based in Monticello. He said he didn't think so. WE FINALLY FOUND SOMEONE WHO DOESN'T KNOW MAX DIRKS! Maybe Roger and Max would like to pay him a visit and correct this.

900 Garfield Ave.

Tipton, IA 52772

Marv Hoppenworth has promised to provide me with some information he has regarding the genesis of Chapter 33. That will have to suffice for now. We must get on with our Trivial Pursuit. I am feeling a bit lazy tonight and so I am going to "borrow" the "Puzzler" I heard listening to CarTalk this week since it was related to flying. The story goes that during W.W.II British bombers were dropping out of the sky at an alarming rate(I believe American bombers were falling at a faster rate since they were doing the daylight bombing). Anyway the Royal Air Force consulted a eminent Mathematician and asked him to look at their shot-up bombers and make some recommendations as to where to put armor plating to keep them from being shot down. The question is: Where did he suggest they put the armor plating?

If you know the correct answer, show the rest of us how smart you are and be immortalized in the next newsletter by being the first one to send it to:
