aircraft electronics expert Bob Nuckolls of AeroElectric Connection.
Snacks: Last names starting with M
by Craig Loomiller
You're probably wondering what happened to my president's column last month. Well here's the story. I actually did write an article, you can go to our website and read it if you want. I wrote it just like I always do and then sent it to our newsletter editor Lynn Coltharp. I usually include it as an attachment with a message in the main e-mail of "here it is, Lynn". At least that was my plan for last month as well; I just forgot to include the attachment as part of my message. I then left town for the next three days. Lynn tried to reach me but was unable to make contact. I'll make up for it this month. I'm sorry Lynn.
Speaking of Lynn and the newsletter, this month's newsletter is being assembled by our web-site editor, Bob Minich. Lynn's brother is critically ill and Lynn has gone down to Texas to be with him. If you get a chance, please say a prayer for his family. I know he would like that. Lynn has included a request in the last couple of newsletters about wanting to step down as the editor. Lynn has been the editor for as long as I can remember. Is there somebody out there that would like to take over the job, I'm sure Lynn would appreciate it. I told him that I would take it over at the end of the year but didn't really want to do the newsletter and be President at the same time. It would be nice if someone would step up and help us out for a while. Who knows? You might even like it.
Back in February, we scheduled an electronics wizard to come in and be our guest speaker. His name is Bob Nuckolls and is from Wichita, Kansas. If you remember, we had a pretty bad snow storm that day and I just knew he wasn't going to make it. Bob has agreed to a return visit. Bob has a website at http://aeroelectric.com/.
If you get a chance, you need to go there and check it out. Be sure to check out the section titled Downloadable Reference Materials. Then select "articles" and you will find a treasure trove of information concerning experimental aircraft and electrical wiring. Be sure to come out for our June meeting. I am looking forward to what he has to say.
I've been spending a lot of time working on a cabin my wife and I bought last winter and it sure is cutting into my flying time. The last couple of times I got to fly my glider, the conditions haven't been very favorable. It always seems like the days I go to the cabin; the soaring weather always gets better. I wonder why that is. I'm getting ready to do a weekend trip down to Talihina again. What a beautiful place to fly airplanes. I'm planning on really getting out and doing some cross-country flying there. I'll let you know how I do.
If you see Dana Ham, please congratulate him on the first flight of his RV-6A. I heard that it went extremely well. I'll see if we can get him to talk about it at a future meeting.
Richie Shroff is always sending me neat little things off the internet and I've been meaning to pass this onto the rest of you for quite some time now. I am now just getting around to it. Richie like myself has found out just what a neat program Google Earth is. If you haven't been there (earth.google.com), you do not know what you are missing. I firmly believe that it is probably the greatest invention so far in this 21st century. I have literally traveled allover the world using this program and it has all been free. Richie asked me to go to the following coordinates and identify what kind of airplane is pictured. Check it out, it's pretty neat.
52-deg 20-min 10.90-sec N
0-deg 11-min 43.24-sec W
This location
is about 100 miles North of London.
I would like to close with an e-mail that Sherrie Redding sent me. Sherrie is a school teacher in Skiatook and the wife of local aviator Jeff Redding. She has put together a summer aviation program for local kids and has asked us to be a part of it. We have agreed and are going to provide Young Eagles rides for the kids. Here is her message:
I just wanted to touch base with you about the Young Eagles Flights on Saturday, June 24. As of today, there are 20 participants (the maximum is 25). I already have the registration forms and will have them filled out when you arrive (I think I have enough...if not, I will let you know ahead of time!)
The folks at Sand Springs Parks & Recreation Department are providing "Breakfast with the Pilots" that morning. Do you know how many pilots and ground crew will be there? I would like to let them know about how many people to expect. Last I heard, they are planning to serve pancakes.
I will help with the paperwork/certificates again. If I know how many will fit into each plane, I can group them together as well.
Thank you again for all you have done for me!
-- Sherrie Redding
Sherrie came out and helped us on our last Young Eagle event and it would be real nice if we have a good turn-out for this event to help her out. Remember to mark your calendar For Saturday June 24th.
See you at the meeting,
Craig

I sure hope everyone had a chance to go to Bartlesville for the Biplane Expo. I had asked a coworker, Keith Farrar, if he wanted to go to the Ponca City breakfast and then on to Bartlesville for the biplanes and he agreed that would be good. Keith has been to Ponca City with me once before so he knew how hectic it can get flying in and out of Bartlesville for the breakfast. I was expecting a lot of traffic especially since we didn't get off the ground until late. I like to get to Ponca around 7:00 to beat the traffic but we were fogged in and had to wait it out for about 45 minutes. The traffic wasn't too bad in Ponca, even though we did arrive later. The food was good and the folks were friendly as usual.
We headed over to Bartlesville and found that a mass of airplanes were trying to get in at the same time we were. Earlier that morning I had called flight service and the briefer warned me that there may be a lot of traffic due to the Ponca breakfast and the Biplane Expo. He wasn't kidding. The radio was non-stop and it was tough to get a word in edge wise. I just called out my position and continued to do so throughout the traffic pattern and I was asked to watch for the J3 in front of me and that was the only communication with the tower I had. Less is definitely better.
The old biplanes were great and the home built biplanes were there in numbers as well. I talked to Charlie Harris the week after the biplane show and he said the quality of the biplanes were exceptional this year. He went on to tell me that there were a total of about 300 airplanes with 75 of them biplanes and 225 non-biplanes. About 1800 gate fees were collected.
The expo had a New Standard D-25 1929 model, giving rides this year. The New Standard can carry four riders up front and the pilot in the back. The rides this year were $40 for a "round the patch" ride or $60 for a 15 to 18 minute ride. The plane was busy both days from 9 AM to 5 PM and gave around 300 people an open cockpit ride. The owner, Rob Lock, aka Waldo Wright was probably very pleased with the turn out. Rob owns another New Standard that makes its home at the Kermit Weeks Museum. The other New Standard that has given rides in the past is owned by Steve and Susan Oliver but has been undergoing restoration. We may see it this fall at the Tulsa Fly-in 50th anniversary.
The honored guest this year was Brigadier General Robin Olds. The general was a West Point graduate and was a tackle on the 1942 West point football team and the team captain. He was also selected as an All American that same year. In the summer of '42 he was sent to Tulsa Oklahoma's Spartan School of aeronautics to learn to fly PT-19s. He went on to fly P38s and P51s in WWII. He missed Korea but went on to Vietnam where he flew F4 Phantoms and commanded a wing of F4s. He had a total of 17 victories, 13 in WWII and 4 in Vietnam, which made him a triple ace. We were pleased to have such an honored guest at the biplane expo.
There were some biplanes that came some distance. The biplane that came the longest distance was Barry Branin from Morro Bay, California. That would be just south of San Francisco. He flew a rare 1935 YMF-5 Waco. There were only 18 ever built and there are only 3 originals still flying. It took an 8 year restoration to bring it up to the Grand Champion award winning airplane it is. You will see that Barry was also Grand Champion at this year's expo. Congratulations Barry!
Charlie wanted me to let everyone know how much the Biplane Association appreciates the help and support that EAA 10 gives to the Expo. He said it takes 200 to 300 volunteers to put the show on and EAA 10 is a big help.
If you didn't make the expo this year there is always next year. Oh yeah, Charlie also wanted to know why he is not getting the hard copy of the news letter. Did you pay your dues Charlie?

Friday the 12th of May, Lynn Coltharp, Paul Shireman and I loaded up the Comanche and made a planned 10:00 AM departure for Hondo. This put us at Bob's BBQ in Ada at 11:15. John Nys, Mark Fridley and Bob Thrasher made a much less well planned departure in the RV 10 around 9:00 or so (amateurs). There was plenty of "Fair Food" at the fly-in so they didn't go hungry, but it certainly wasn’t Bob’s.
It was a beautiful day and both flights were uneventful. We arrived in the Hondo area and began the convoluted published approach procedure about 1:15 PM. The approach for arrivals from the north involved over flying three or four local landmarks like bridges, highway intersections, water towers and cemeteries. We actually found at least half of them. There wasn't a real high traffic load, but there was considerable confusion on the approach frequency. Maybe it was caused by the Tiger Moth replica that was flying the approximately ten-mile approach route at 45 mph!
We were finally handed off to the tower and completed most of a normal approach. Then there was some type of confusion on the runway, aborted takeoff I think, and we were given a request for a 360 on final at about 400 feet with full flaps. I was busy moving levers and knobs, and watching the air speed, but Paul seemed to be clenching at something in the right seat. Probably just stiff after a long flight?
We taxied clear to the east side of the airport and there were only a half dozen or so camping spots left. We had jackets on at Gundy's, and the camping gear was still cold as we pulled it out of the baggage compartment, but it was HOT at Hondo! I think it was just a shock, because it didn't seem too bad after we had been there for a while.
The campgrounds are fine and some nice new showers are close by. It's too far to walk to the main show ramp, but the shuttle service was pretty good. I think that they were running five most of the time.
We found the John, Mark and Bob on the ramp and visited with them a couple of times before they left for home around 5:00. We also ran across John Hudec's beautiful Waco and found him shortly afterward. Of course he took home all their gold.
There were lots of nice planes of all varieties. Lynn and Paul looked all the Rans planes over closely and talked to some of the owners. I think that visiting fly-ins while you are in the middle of a project must be when it is the most fun.
We departed around 10:30 Sunday morning into a 600 foot overcast. We circumnavigated some thunderstorms in north Texas and fought up to 35 mph headwinds, and some rough air on the way home but arrived back at Gundy's a few minutes after 1:00. I talked to John Hudec at the Biplane Expo and was relieved to find that he had finally made it back home. Actually it only took him a couple of days with an overnight in Fredericksburg. The low clouds and thunderstorms didn't get any better until Monday and the headwinds never did let up.
All in all, it was a very nice fly-in. They had good food and entertainment both nights. Music on Friday and Mike Melville, the first civil aviation astronaut, gave an interesting talk on Saturday night. There were lots of forums on Saturday. The facilities at the old airbase are very nice; there is boundless ramp space, and adequate camping and RV parking. The Hondo city officials were introduced Saturday evening and appeared to be excited about having the event. If you want to stay in a hotel or motel, San Antonio and five smaller towns are within five to 30 miles. There was shuttle service advertised to area motels starting on Thursday, but we didn't really check it out.
Maybe SWFRI has found a home after bouncing around south Texas for the last eight years.

With the high stress already exerted on the propeller during normal operating conditions the last thing your propeller or engine needs is an overspeed condition.
What exactly is an overspeed condition? Every engine has an RPM operating limitations. Exceeding that limitation or exceeding redline is an overspeed and can tear the propeller, engine or airframe up in a heartbeat if the rpm is too great. Although most overspeed instances are not of a severe nature, it is still imperative that the proper action is taken after any overspeed condition occurs.
What can cause an overspeed condition? An inaccurate tachometer, a faulty propeller or a faulty governor is at the top of the list. In my personal experience while performing dynamic balance, I have found an average 90% of all mechanical tachometers to be out of tolerance. I found one the other day that was indicating 175 rpm less then the actual rpm. In that situation, the pilot thought he was flying at 2500 rpm when he was actually flying at 2675 rpm. Lucky for him, the red line on that aircraft was 2700 rpm. In these type of cases the overspeed condition is usually not severe but can go unnoticed for a long time.
When the propeller or governor fails, the overspeed can be much worse and require immediate action from the pilot in command. I don't have the expertise or credentials to instruct any pilot on what action to take if an overspeed condition occurs. I can tell you that different propellers, governors & types of aircraft all operate a little differently from one to the other. A twin-engine aircraft for example almost always uses oil pressure for low (fine) pitch/high rpm compared to a single engine aircraft, which will use oil pressure for high (course) pitch low rpm. Hence! A Twin-engine propeller will seek the feather position when there is a loss of oil pressure and a single engine propeller will seek high rpm (overspeed) with a loss of oil pressure.
Remember what I said! Not all aircraft operate the same. A single engine aerobatic propeller can operate like a twin engine and seek high pitch with a loss of oil pressure. As you can see, it's very important for the pilot to know how the propeller operates on the aircraft they are flying. I can tell you this: With an out of control propeller/governor, it can be possible to control the rpm to some degree with power & airspeed. So I will recommend that one of the first things a pilot do is: Retard the throttle to idle if you're at a safe altitude. The second thing a pilot should do is: Reduce your airspeed if you're at a safe altitude and have the airspeed to reduce. Of course the list goes on and on of things to do and I suggest you consult your flight manual for the manufacturer's recommendations.
Now what action should you take if your bird experiences an overspeed condition? The propeller manufacturers want to know how much a propeller exceeded the rpm in percentages and for what length of time. Each manufacture has different criteria so you will need to consult a propeller shop or propeller manufacture for the action required. For example: You could go to my website www.customprop.com and click on the link (information) then (McCauley) There you will see service letter 1998-23. This service letter will show a chart of the action to be taken based on percentage of overspeed.
One final thing: It is recommended and in some cases required for the tachometer to be checked for accuracy at each annual inspection. Custom Propeller will perform this check free of charge as a courtesy if you fly into Gundy's Airport (identifier O38) home of EAA Chapter 10.
Name a similarity between an air traffic controller and a pilot.
Be the 10th person to email me with the answer and you will win a prize!
Thank you for taking the time to read this news letter. I hope it will be of some benefit to you and hope that you will pass it along to your friends.
As always you can visit my web site, 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. Until then y'all have a great day and be careful!

I have been doing the newsletter for longer than I can remember and it would be good for the chapter to get a new slant on the newsletter. Burnout has set in on me.
So – this is a plea for someone to take over the newsletter for a while! Don't be afraid you will get "stuck" with it forever. Like last time, when Bob Minich stepped in, I will be willing to get "back on the job" after I have enjoyed a period of time away from the newsletter.
Please let me, or one of the chapter officers, know if you would be willing to take over the newsletter for a while.
Thanks
Lynn
