I believe one fellow last year mentioned that he was having intermittent cutout with it but he finally traced it down to a wiring short outside of the radio. I plan to put one in the Europa motorglider that I'm building right now. I like the fact that it's small and has the builtin intercom. Perfect for a two-seater.

I wonder how far into Mk-3 production the aluminum H braces went? My Mk-3 was #90 and as all the H braces were installed by the original owner before I bought the project, I do not know what mine are.

Perfect for a | two-seater. Doug/All: Mine too, Doug. How well does the intercom work? Was not clear whether it had a PTT capability for intercom or "turn on, leave on" as I understood from all the searches I did for info last night. Sky Sports sells a wiring harness for $190.00, which is way too much for that. Are you familiar with the requirements for wiring the radio? I wonder if the plug on the wiring harness comes with the radio? If so, it probably will not be that difficult to do my own wiring. Most of my intercom/VHF comm problems have been traced to wiring damage caused by the infamous rats a couple years ago. Every once in a while more damage in the form of chewed wires and cut wire insulation appears. They can do a lot of damage and in places one can not see.

Mine is SN: M3-011, Feb 1991. I am sure Dennis Souder has a good idea when. You can look in the tail boom and see. The aluminum H brace uses very heavy wall tubing and is easy to identify with flash light and eyeball. Primary rivet loosening is near the center of the H brace. Nothing bad, at this time, but definitely getting loser. I was thinking about blocking the fuselage to neutralize the weight on the tail boom, drill the old rivets out and replace. First tell/tale sign of rivet working was the aerothane paint popped off the rivet heads.

I cannot remember Ted, I think we are all concerned about the potential for fires with our planes whether we're aware of it or not. From simple refueling safety to minor leaks or major ruptures such as in a crash. Dallas Shephard recently crashed his Mark 3 and there were no real bad injuries but fuel was running on him and his grandson. He couldn't reach the master switch as I recall.

I cannot remember Recently, at a local airstrip, a wooden experimental [not an ultralight] apparently stalled & pancaked in. Pilot may have survived the impact, but the landing gear sheared the fuel lines & the pilot was engulfed in flames within seconds. The sliding canopy was jammed & he could not open it. The flames were so intense that rescuers could not get to him. The pilot, while screaming in pain, was able to climb over the back of his seat & kick out the side of his burning fuselage & crawl out far enough for rescuers to drag his burning body away from the inferno. Except for metal parts, the plane was consumed in under 2 minutes. Mostly third degree burns over 92% of his body. The pilot lived for a week until they removed life support. We are now planning on maintaining a"'crash-cart" at our field with several fire extinguishers, lots of sterile water, crowbar, axe, firemans coat & helmet,& what-ever else we can think of , all on a fast golf cart.

I really never thought much about fires in a crash...till....at our airpark..about a year an a half ago...a fella in a CGS Hawk took off and for some unknown reason To any of us....got up about 2 or 300 feet...and maybe a half mile...and his bird did a slow wing over and went down..(I didnt see it..I was inside a hangar)..but thats what the boys all said...anyway....when a crowd went running by the doors I went out to see what the commotion was...and looked downfeild..all I could see was the fire... BY the time we got there..(Old men running thru waist high soybeans dont make real good time)...Well..we dont know if it was the crash or the fire that killed him...but is wasnt pretty..and..it was the first time I walked up on a airplane fatality.. It took me awhile to be able to sleep after that of course. What was just about as bad was when a month later...his wife/widow showed up at a fly-in we were having..with his pick-up and all his extra airplane stuff in the back..wanting to sell it all...Of course..his Life-Insurance would not pay off and she was in financial straights... One of the Fellas who was in our crowd when the Hawk went down..and actually..being the Youngest..was the first to make it thru the beans..Had a Z-max...and he is a real smooth pilot...Younger family man(mid-30s)..About 6 months after that crash..he was down low Buzzing a buddies house when he had an engine out....He set it down easy in an adjacent feild...but he got in some mud and it did a nose -over ..didnt look all that bad but when the top of the rudder hit...the fuse busted in half behind the seat...and left the top of his nice eros style full enclosed canopy sitting on the ground. HE could not get out...and...gasoline was running all over the place. NO fire....Now...his buddy didnt see this happen right away and it was they think 15 or 20 minutes before he got over there and lifted up the tail so he could get out. According to his bud..he was almost catatonic....no injuries...but on the verge of insanity. ( or maybe past it)...He will never fly again he swears...and has been in psyco therapy for a year now, and hasnt worked since.. about a month after his crash I might add...his wife called during a club meeting about half hysterical...said he was going to burn down the house..She asked if we would come over and get that wrecked Z-max..because he was going to burn it and it was in the garage...which of course we all loaded up and went..This actually was the first time I personally had seen him since before his crash...And Ill tell ya...I didnt know him anymore..Even his face had changed...I left there more shook up than after the fatal crash. So...as of this last year..It has got me thinking about fires..and making sure I have a good vent design...Fuel pump switch where I can get at it...and what ever else gives me piece of mind.. AS Green said...."Because I want it"...well..thats good enuff for me..and IF I had any good knowledge about how to go about that switch to share..I would attempt to help figger out a good way to do it.. PARTICULARLY if it would keep me from running into anymore wives in the situations like I have seen recently... The combined abilities and knowledge and expierience that is present in this forum would make me believe that if I wanted to make my Kolb fly to the moon....well...this is where I would start asking questions....and hope that just cause all of the talent that is present here didnt think I was gonna get my Kolb to the Moon...I would hope that they all would contribute what they could anyway...

I could even lose power by hitting a bad bump on summer day? ------------------------------ No it would kill the radio, fuel pump, gps, intercom, lights, etc. the engine does not require outside power to run... cdi will work without 12v input. boyd ---------------------- All ELTs have inertial switches, that can be "unarmed' or switched off.

Intuition tells me that thin aluminum legs on the H-section would add little strength to the inside of the fuse tube. The Original Firestar has chromoly steel in both the wings and fuse tube. Old Kolb did it right the first time. I wonder if the new Kolbs are aluminum too. Somehow, I missed this bit of information over the years or the senior moments are becoming more frequent. I have 2500+ landings on mine and don't see any signs of loose rivets on the fuse tube, but then my Kolb is 540lbs gross. I've noticed, John, that you stand on your fuse tube to look at the top of the engine. I have never stood on mine. Even with the chomoly H-section, I would think my weight would stress it quite a bit. I have noticed the main 3/8" bolt has loosened up a turn or two after 15 years. Those bolts in the wings have locktite on them and this one didn't. I made my last winter flight of the season up here in the great northland. I landed on skis out on the lake about 12 times. It's getting too warm, too fast. Yesterday was blue skies and light winds with a high of 34F. The lakes are melting and there goes my winter flying activities.

Sometimes discussions get into finer points of engineering and physics and stuff, which is always interesting, but sometimes the practical matter is that some of the distinctions aren't terribly significant when it comes to actual performance. For someone considering the purchase of a 912 or 912S, I can offer a similar experience to John's. At a flying weight of around 920 lbs, my 912 powered Mark III was still climbing around 450fpm at 10,500 ft, the outside air temperature was around 36F. Maybe with computer controlled fuel injection it would be doing better, but I was cold and ready to stop climbing and come down. Actually, I like to fly along at about 10-15 feet, it makes it seem like you're going faster. ----- Original Message ----- From: "John Hauck" Subject: Re: Kolb-List: Bing 64 - Auto leaning like HAC? > --> Kolb-List message posted by: "John Hauck" > > | The Bing 64 sort of compensate for pressure changes by default > because it is > them.

You can also find a lot of discussion on the AeroElectric list archives, Bob Nuckoll's used to sell them and has a wiring diagram on his web site. It is a great little radio. I can't turn the knobs with gloves on, and you'll want to mount it where you don't have to stretch too much to get at it, because the controls are small, but if you can fit it in a convenient spot it's really nice to use. If I was starting from scratch and a new panel layout, I might look at the ICOM, or something with bigger knobs, but I'm happy enough with the 760. The performance is great. When I first installed it I thought I was picking up RF noise somewhere and went to a lot of trouble moving wires, different antennas, etc., until I figured out it was just cockpit wind and engine noise. With the enclosed cabin it's working a lot better. I'm using a Sigtronics SPO22N portable intercom, permanently mounted to the panel. ----- Original Message ----- From: "William George" Subject: Kolb-List: MicroAir 760 > --> Kolb-List message posted by: William George > > John and troopers, > > I have been using one for a couple of years.

The bent/destroyed wing that I rebuilt had one in it and even though the spar was bent like a banana, the H was fully intact and undamaged. The previous owner was kind enough to include a new steel version in my purchase. The big drawback is repairs, where the rivets go into blind end holes. I cut it up to remove it and the spar from the ribs.

The instrument panel switch while enclosed is not necessarily sealed. The same could be true for the master solenoid depending upon the specific switch. The presence of just the right air/fuel mixture is the key factor - you could submerge the switches in fuel and nothing would likely happen - but put them in just the right air/fuel mixture and even the small arc would ignite the fumes.

I sold several dozen EBC ELTs in early 70s, and installed a lot of them...and cked installations done by others. The worst...and many...were the installations on the leftside cabin interior, right below the windshield on 172s and 150s. This is a piece of .032 or thinner without any stiffening.

GM, 530.587.4119 Dear Fabric Piper Owner / Enthusiast, Thank you for your interest in the upcoming restoration seminar. As the fabric Piper fleet ages and newer, younger owners and restorers take over, I find an ever increasing need to educate the current and future generation of owners and rebuilders on what the standards were when these aircraft were built, the oldest of which are now over 60 years in age. I can sense this lack of knowledge by the questions that are asked and all the phone calls and letters that I receive. The "Type Clubs" 'are doing a great job passing on information and experiences among the membership, but there is still a missing link, especially for those who don't belong to an owners club. It is for this reason that I have decided to put my restoration work to the side and conduct a field training program where I can go to the people, alone with various training aids, and work with them in small groups instead of one on one by mail or over the phone as I have been doing for nearly 20 years now. By using slides, video tapes, diagrams, and actual "hands on" methods of instruc=C2=ADtion and demonstration, there is not a more effective way to pass this information across. An additional advantage is the camaraderie and friendship among the students and the sharing of information and experiences of other students. That's what it's all about. With nearly nineteen years of my life spent working for Piper in such capacities as drafting, technical writing, technical instruction, product support on all the older models, and when called back to work in Vero Beach, was a man=C2=ADager and creator of the Cub Kit program. With all this experience and exposure, I feel well qualified and capable of con=C2=ADducting this mobile school program. I also own four fabric Piper models myself. A 1946 J-3, a PA-12, a PA-15, and the prototype PA- 16 Clipper. This is my goal, to preserve the past for the future, and pass this information on so that these fine airplanes may be preserved, maintained, and enjoyed well into the future. Now to tell you a little more about the upcoming seminar. By the way, if you don't even own an airplane yet, this is a fantastic way to familiarize yourself with each of the models and find out all there is to know from service problems to performance specs, and what you might expect to pay for a particular model that you are interested in. On. the first day we begin with a presentation of the Genealogy of the early Pipers. We'll discuss all the FAA AD notes that per=C2=ADtain to the airframe, engine and accessories. As the class progresses we'll go over the whole restoration process in great detail from tear down to the final inspection and test flight. We'll discuss cleaning, inspection, fabricating parts, and where to get parts and supplies. We'll also talk about covering, painting upholstering, and final touches. There will be demonstrations and a chance for some "hands on" experience. We'll end up with rigging and annual inspections. If time and space allow, workshop duties will include rib repair methods, wing panel tramming, rigging, Graco/Croix paint sprayer demonstration, and even fabric covering and stitching. Each student will receive an information packet including a notebook, pen, and a generous supply of very informative handouts. Decals and some small parts will be displayed for sale during the seminar. Old photos and factory reference books, along with currently published books on Piper history 'II also be displayed. Video's pertaining to Piper history will be shown during evening hours. If desired. workshop duties may continue after the final day, and I will be available, for a fee, for small duties or consulting. Coffee and doughnuts will be supplied, complimentary, every morning. Lunch and dinner will be up to the par=C2=ADticipants. EAA Chapter 1073 will have their BBQs going for a nominal charge and the classroom and instructor will be available for hangar flying. Group dinners at a local restaurant seem to be a popular idea. Don't delay and miss out. Class size is limited. The seminar tuition will still be $300.00 per person for the 2004 year, with spouses and family members under 21 at half price. Returning students from previous seminars will also be half price if space allows. As a courtesy to the host, and for plan=C2=ADning purposes, please pre-pay at least 6 weeks in advance(April 9, 2004). Checks may be made out to Cub Restoration Services. The instructor reserves the right to cancel a class if attendance is not sufficient. All funds received will be returned. Your host will provide lodging and transportation information as well as directions to the seminar site. Come join in and be a part of this friendly and informative session, and bring some photos of your airplane or project with you. I'm looking forward to meeting you.

I was taught the same as Russ when learning to fly - in Cessnas. The reasoning is that the doors can jam shut in a crash, preventing exit from the plane........and that is a very possible scenario in a 152 or 172. With our Kolbs, it's a whole different set-up, and different rules could apply. In the case of the Z-max that Don mentioned, I believe that has a bubble canopy that lifts up for exit from the plane. Since the plane was on its' back, the canopy couldn't be lifted, and the pilot couldn't exit. I'd a gone loco in such a situation, too, with gas pouring all over me. With the Kolbs, it's hard to picture a crunch - in a Mk III - where you couldn't get out one side or the other. You'd sure have plenty of incentive. Also hard to picture the doors jammed closed, tho' I guess Murphy's Law applies here as much as anywhere. Seems to me, never having been there, that they'd be more likely to pop open. Also, in flight, I don't think you could open the doors on a Mk III if you wanted to. What do you think, John ?? Lar.

This guy was using the overvoltage module that causes your alternator circuit breaker to open when the output of your alternator goes above 16 volts or so. His problem was that when he released the starter switch, the voltage spike from the starter contactor coil caused the overvoltage module to trip. Pretty interesting problem to debug. It's relevant to this discussion because it points to a potential problem - the spike from the starter contactor can cause an arc that eventually destroys the switch. I didn't use the Rotax starter contactor on my 912, I used one from B&C that had the spike-catcher diode already installed. If you are using the Rotax contactor you may want to see if arcing is causing any wear to your starter switch. http://www.matronics.com/searching/getmsg_script.cgi?INDEX=1396535?KEYS=master_&_diode?LISTNAME=AeroElectric?HITNUMBER=250?SERIAL=12022313057X?SHOWBUTTONS=YES ----- Original Message ----- From: "jerb" Subject: Re: Kolb-List: crash fires > --> Kolb-List message posted by: jerb > > John & All > Even if a master switch is used, when you trip the panel switch some arcing > will occur on both the panel switch and the master solenoid as the > contracts break.

You can make it a momentary contact switch like a PTT or a panel switch to leave it on all the time. The Sigtronics intercomm was very easy to hook up just the mic and headphone line to the pilot's side of the Microair. The intercom delivers sound to both. I didn't use the PTT wiring of the intercom, I just wired the switch directly to the Microair. Works like a champ. ----- Original Message ----- From: "Jim Ballenger" Subject: Re: Kolb-List: MicroAir 760 > --> Kolb-List message posted by: "Jim Ballenger" > > John > I have talked to Jabiru USA several times about the MicroAir 760.

I was wondering what kind of wire can or should be used for shielded kill switch wires? I have some 18 gauge shielded "security system" wire. Would that work ok for the kill wires? Is there anything else that I should be doing? Do you just shield the kill wires or must I shield the a/c alternator wires going to the rectifier / regulator? I have installed the resister spark plugs but have not installed the shielded caps or ign. wires. I have not had a chance to recheck it since replacing the plugs.

Rather than respond to all of them, this will save me some time. Again, Thanks! I looked at Sky Sports who also sell the MicroAir 760 and the wiring harness. Sky Sports wants $190.00 for the wiring harness. Seems a bit much for my budget, or any one else's, for that matter. Charles, where did you get your radio and wiring harness? Would you mind telling me how much you paid for the harness for the VHF? Aircraft Spruce has the VHF for 743.00, but did not see anything about the wiring harness. Guess could call them in the morning and see if they have it and how much. BTW, that was the best price I could find on the MicroAir 760. How about the intercom? Did you use a seperate intercom or the one in the MicroAir? Duncan McBride uses a Sigtronics intercom. I already have one installed in the aircraft, a Sig 400SN. Anybody got anything else on this radio, or a good alternative, let me know.

I get great results with it, and I didn't even install it correctly - one end should go up and the other down, and I laid them sideways. Anyway, it worked as well as a 1/4 wave whip and a 20" square ground plane in the rear of the fuselage like Richard Pike's, so I stayed with the dipole. A piece of coax runs from the radio to the nose where the center conductor exits the shielding. Equal lengths of the center conductor and shielding separate 180 degrees from each other and extend in as straight a line as possible, which isn't very far. Mine run from the nose just about back to the instrument panel. But it works ok. I'm hunting for the link.
