Our next meeting will be Monday, January 16th, 2006 7:30pm
at the chapter hanger at Gundy's.
Snacks: Last names starting with A-C
I hope everybody had a Merry Christmas and a Happy New Year!
We had a really good 2005 and hopefully 2006 will be just as good if not better. We will have a small change of officers this year. Larry Brooks who was our Secretary for the last couple of years decided not to run again. Larry has done an outstanding job in keeping the Chapter's paperwork in order. I know I appreciated the fine work that he did. Bob Thrasher, who has been a member of Chapter 10 for several years, will now replace Larry as Secretary of our organization. I know Bob will do a good job at Secretary. I hope everyone is aware that we will now have two confirmed glider nuts in leadership positions of Chapter 10. I’m just giving you all fair warning.
If you didn’t attend the Christmas dinner, you sure missed a good time. I believe by the time it started, we had sold all of our available seats for the event. Thank you for your participation. The dinner was catered again by Jamil's, which always does a good job.
Although I didn’t see any of the usual gag gifts this year, I know they are floating around out there somewhere waiting for next unsuspecting person. Be careful, it just might be you next year.
Bart Dalton did his usual excellent job in rounding up a large number of door prizes. I think we especially need to thank Aircraft Specialties for their generous contributions this and every year.
It is time to start thinking about candidates for this year's EAA Air Academy scholarship. For the last several years, Chapter 10 has sent a scholarship student to the Air Academy with all expenses paid. This is an excellent opportunity for a young person to experience aviation in all its glory. If you know a young man or woman between the ages of 12-15 that you think would benefit from the experience, be ready to submit their names. Jeff Wedman will write an article for next month's newsletter that will spell out all the details. I think the entry deadline will be March 30th again this year.
The fire danger out there right now is extremely critical. We had an incident on Gundy's airport a couple of weeks ago where sparks coming from an aircraft caused a small grass fire. Everybody needs to be extra careful right now. Boy, we sure need some rain right now. Lynn Colhtarp joked last week that what we need is one of my patented Poker Runs, preferably the sooner the better. (It must be my knack for scheduling rained-out events.) I don’t know about next week but I do think we ought to have one some time this spring for sure. I’ll let you know when it is going to be.
We are fortunate to have Bob Warren as our guest speaker this month. Bob was a fighter pilot in WWII who flew Warhawks, Lightnings, and Mustangs in combat. The Tulsa World featured him in an article a couple months ago. It seems he P-40 Warhawk that Bob flew and later abandoned on an island in the Pacific Ocean was recovered and recently restored to it's original condition, right down to Bob's name on the cockpit opening. He recently went down to Australia to dedicate this restored aircraft. He has been in aviation his whole life including building his own experimental aircraft. One of the aircraft Bob built is currently hanging in the Oklahoma City Air & Space Museum. It should be an interesting meeting. I hope to see you there.

I hope everyone had a happy holiday. It has been a wonderfully mild winter so far. A little dry, but lots of warmth and sunshine. Let's hope that it continues. There may be dark clouds on the horizon. Craig Loomiller is itching to schedule a couple of poker runs, and we all know what that means!
A new year is upon us. That means dues time again. Still only $20. Probably one of the biggest bargains you'll ever find. Good people, a lot of good information and we seem to feed ourselves pretty well. It's easy to renew, too. Just fill out a simple membership renewal/application form and mail it in or bring it to the next chapter meeting on Monday, January 16th at 7:30PM. See You There!

The following article applies to McCauley Constant Speed propellers only. But that doesn’t mean you should ignore the information, you never know when you might be hitching a ride with some one that does. If all Hell breaks loose, You will know what to do!
Ok, Now that I have your attention, lets start with: What is an Oil-Filled Propeller? McCauley has for a number of years been manufacturing most of their constant speed, full feathering and turbine propellers with the internal hub cavity filled with oil. Most of the turbine propellers use “light weight turbine oil” while all the others are filled with “light weight (20wt) reciprocating engine oil”. This oil within the hub cavity is independent of the engine oil going to and from the governor which, as you know, changes the pitch of the propeller blades to control the rpm.
The only time the two oils might mix is if there were an internal oil leak past an o-ring and yes you guessed it, that is why they use the same type of oil as what's in the engine except the internal hub oil is a very light weight. On the reciprocating engine propellers they also add a small amount of red dye, which mixes with the oil. You can identify an oil-filled propeller by a change letter at the end of the model designation. For example: D2A34C58-O. The “O” at the end indicates this model of prop has been modified to the oil filled version. The change letter will vary with different models. However the easiest way to determine if your propeller is oil filled would be to look for a small filler plug located on the hub. Usually a 1/8” pipe plug.
So why the oil filled modification? Well McCauley says, "Its number one reason is for improved lubrication and the number two reason for crack detection." I won’t argue with which reason should be number 1 or 2 as I know from first hand experience that both reasons are good reasons and best of all, it really works! If you stop and think about it for a minute, with a tightly sealed propeller hub with about a quart of oil that has no place to go will definitely provide excellent lubrication and hardly any chance of internal corrosion. If the hub or blade shank area were to develop a crack then centrifugal force would force this red dye oil out of the crack and onto the cowling and windshield for the pilot and/or hitch hiking passengers to see.
In this article I explained what an oil filled propeller is, how to identify it and why the oil is there. Next month I will continue this article explaining oil leaks from these types of propellers and what to do about them.
Can you guess the highest altitude ever reached by a propeller-driven airplane?
Special Note: As always you can visit my web site: http://www.customprop.com/ to read up on this article or any past articles that I have written, for the answer to this month's question and your entire propeller needs and prop information. Stay safe and stay tuned next month for the next prop tip.
P.S. Happy New Year!
Dr. Dan, The Prop Man
Sad news! I just noticed in the newspaper that Dr. Ed Felmlee (one of our charter members) has died. We will miss him.
Our thoughts and prayers go out to his family.
Some of you may know this already. It is kind of interesting to note that at the 6th, 7th and 8th houses down the West taxiway off the North end of Gundy's three Rans S6's are under construction.
The builders are Clarence Larsen, Paul Shireman and Lynn Coltharp. Clarence started his project last April and he has it covered, painted and the engine hung. Paul and I started in October and we have the fuselage constructed and ready to start construction on the wings.
The construction of these airplanes is a welded steel fuselage and aluminum tubular tail cone with aluminum tubular control surfaces. The wings are also aluminum tube construction including aluminum tube spars. All the aluminum tubes are put together using Cherry-Q pop rivets with stainless steel used in the high stress places and aluminum used in less stressful areas.
We all spend a lot of time visiting each other's hangars asking questions and getting ideas and help from each other. Of course Clarence has been a real help to Paul and me since he is ahead of us in construction. All the "back and forth" makes the project a lot more fun.
The construction seems to go fairly quickly, however, I seem to always come up with a confusion point at each step. The tech help at RANS always has the answer I need and are eager to help. One point of criticism is that they don't seem to have updates and corrections/clarifications to the plans and drawings. This would save them lots of phone calls and save the builders time trying to figure things out on their own.
Anyway we are all having fun building these Light Sport Aircraft and I know we will have a lot of fun flying them.

One of the many benefits of being a member of Chapter 10 is having our own in-house Designated Airworthiness Representative When Chapter member Bart Dalton became a DAR several years ago, he made it a point of performing certification inspections at no charge for any Chapter 10 member. This program has worked well throughout the years and well received by everyone involved. We have had a few people though who have stretched the limits and the intent of this service. To avoid problems in the future, the Board of Directors have been forced to make a policy change concerning this service.
There are now two criteria you must meet to use the Chapter DAR services at no charge:
We have had to make these changes to ensure that this remains a Chapter benefit. We are sorry if this inconveniences anyone, but it was done for the good of all members.

The chapter hangar is still decorated in all it’s regalia from the Christmas party. Well, we did fold up the table cloths at the monthly board meeting on the 9th of January. All the stuff in the ceiling and on the walls is still adorning the place.
Monday the 16th of January is our regular newsletter folding "party" and we decided that would be an opportune time to "de-decorate." So come join us at the folding party and help with the de-decorating. It will not take long if we get several people to show up and help.
By the way, John kurt normally brings a "tall" step ladder to get the stringers disconnected from our "chandelier" so if anyone has a TALL step ladder we will probably need one.
