    Subject: Dynon (or why Dan C has little IMC time)
    From: "Jim Robinette" <jim@rvator.net>
    --> RV-List message posted by: "Jim Robinette" <jim@rvator.net> I would also guess the reason Dan has so little IMC time is that he lives in sunny SoCal, where IMC can be hard to find on most days! If only we were all so lucky.

Only 15.3 of that is instrument time (24 approaches). So it's not like I'm doing a ton of hard IFR or anything. )_( Dan RV-7 N714D http://www.rvproject.com

    --> RV-List message posted by: "LarryRobertHelming" <lhelming@sigecom.net> I have only 36 hours flying to date. But the other day while just flying along in the clear with somewhat calm winds/updrafts/downdrafts I just glanced at the Dynon and saw it displayed something briefly to the effect that altitude reporting was being discontinued. My standard (old iron) altitude backup display still showed what I consider to be the correct altitude and my Garmin 327 with a Sandia encoder still showed what I consider to be a correct altitude. I have also noticed occasionally the attitude display of the Dynon will show a slight bank momentarily when none is there. I cannot recommend anyone rely solely on the Dynon for IFR flight.

    Subject: Re: Dynon
    --> RV-List message posted by: "Doug Rozendaal" <dougr@petroblend.com> I too use my Dynon as a primary IFR instrument. I too back it up with a Steam gauge Alt and AS as well as a NAVAID autopilot. I am coming up on 2 years and 400 hours with mine, I don't log IFR time closely, but I would bet I have much more than 15 hours of actual time on mine, and I have flown several approaches to, or nearly to minimums. My experience would cause me to echo Dan's comments. If you plan to fly IFR in an RV, no matter what kind of gauges you use, you need to a current and profficient instrument pilot.

What happens is the end play of the crank and drag on the prop is forcing the crank aft in the bearings. Contact Lycoming tech support about crank bearing/crankshaft match issues.

    --> RV-List message posted by: "elsa-henry" <elsa-henry@darlor-watch.com> I wouldn't use a toy baloon as an indicator of a slow leak in your fuel tank under test! All toy baloons have inherent leaks through the porosity of the rubber and will deflate over time. I used a latex surgical glove wrapped and taped to the test vent tube. I Inflated it to twice the size of my wrist...Left it on for week and remained the same (on both tanks) Cheers! Henry Hore. 6-A, C-GELS

    --> RV-List message posted by: "Bob Collins" <bcollinsrv7a@comcast.net> Why not just use the manometer method with the Van's test kit to close off the fuel valve? It works great. A little soapy water and voila! If there's a leak you'll know about it in a couple of seconds.

    Subject: Tapping holes in the canopy frame
    From: Mark Schrimmer <mschrimmer@pacbell.net>
    --> RV-List message posted by: Mark Schrimmer <mschrimmer@pacbell.net> The instructions say to tap the sliding canopy frame and roll bar with a 6-32 tap. The instructions say to drill with a #35 bit and the plans say to use a #36. Which is correct? Also, I see there are several different types of taps available--plug, taper and bottoming taps, with left and right-hand threads. What kind is best for the canopy frame? Last, but not least, is a 5/32" hole in the plexi adequate for expansion, or are some of you drilling the holes larger? Thank you, Mark

    --> RV-List message posted by: Phil Birkelbach <phil@petrasoft.net> #36 drill. You want a right hand through (plug) tap. These would be the most readily available taps. Lubricate the cut with some cutting fluid, keep the tap as parallel with the hole as possible and blow the shavings off of the tap before you back it out and you will have some great threads.

The only answer I can come up with is that the aluminum line suffered a fatigue fracture which weakened the tube and the hydraulic pressure finally blew out the chunk. The line has a loop to provide flexing as the caliper moves in and out - but, flexing aluminum is not know for a long life. In all fairness, there are many RVs flying with this configuration - so the break might be attributed to my installation (stressing the line when I put the loop in it), material weakness, some damage I did not notice, etc. Had over 300 landings before the failure.

Us aviators are ALWAYS "looking forward" . . . to preventing further occurances of preventable accidents (Air Force safety jargon?). Sincerely, you are "breaking new ground" in the area of brakes. (no double pun intended on breaking a brake line?) I've always known I'd never use plastic brake line (many have, and have melted them and lost brakes during/after high speed taxi practice or hard braking on landing). You have just drawn a perfect conclusion from yet another "brink of disaster but saved by the grace of God" event (God MUST love you greatly!!): Aluminum does have crummy fatigue life. So maybe I'll get some automotive steel brake line to fit or adapt to my Cleveland aircraft brakes.

The only answer I can come up with is that the aluminum line suffered a fatigue fracture which weakened the tube and the hydraulic pressure finally blew out the chunk. The line has a loop to provide flexing as the caliper moves in and out - but, flexing aluminum is not know for a long life. In all fairness, there are many RVs flying with this configuration - so the break might be attributed to my installation (stressing the line when I put the loop in it), material weakness, some damage I did not notice, etc. Had over 300 landings before the failure. > >Ed > ----- Original Message ----- > From: John Slade > To: Rotary motors in aircraft > Sent: Friday, June 24, 2005 9:09 AM > Subject: [FlyRotary] Re: Brake Line Incident Photos > > > Wow, Ed! > You're luck the airplane wasn't consumed. > My question - how did that big chunk get blown out of the brake line? > Regards, > John > -----Original Message----- > From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net]On Behalf Of Ed Anderson > Sent: Friday, June 24, 2005 8:58 AM > To: Rotary motors in aircraft > Subject: [FlyRotary] Brake Line Incident Photos > > > For those interested (and may not have seen them) , here are a few photos of my brake line fire incident. > > Big chunk got blown out of brake line as can be seen from Brakelines.jpg photo.

I am told it may take several days before the photos are posted and a notification sent to the RV list. If its not there by Monday, I will try again. Not trying to say that the design is bad, could have been my installation, unnoticed damage to the line or even a material defect. I am aware there are several hundred RVs flying with aluminum brake lines. However, I've also discovered that I am not the only one to have the aluminum brake line fail on an RV. So just wanted to past on the incident I experienced to others on the list. Ed A

    --> RV-List message posted by: linn walters <lwalters2@cfl.rr.com> A short length of flexible, high pressure line would go far in preventing fatigue failures of the aluminum line. I'll probably do that on my -10. Hadn't thought about 'till now. Thanks for the heads up guys (and gals)!

    --> RV-List message posted by: "dick martin" <martin@gbonline.com> Dear Stan, Many of us camp out at OSH, not necessarily out of necessity, but mostly because of the comadarie that is available in the camp areas. It is usually difficult for flyin visitors to get to places in town. However, there are many possibilites for get togethers in the camping areas. It is possible to rent campers etc for the flyin. The OSH vendors are usually booked, however, others are available. If interested, I can provide some names etc. Do not wait until the last minute, because all rentals will be taken. Now , to your original proposal, I would like to see a get together in the camp areas because of the convenience. Do not ask EAA about refreshments ( alcohol, beer etc) as they will advise you NO.

One of the problems I had with rivnuts in general is that you have to drill a pretty large hole to put them in. There is not a lot of room on the canopy frame tubes. I'm going with glue for my canopy and skirts. The canopy is done, and I'm real happy with the results. Skirts are next. -- Mickey Coggins http://www.rv8.ch/ #82007 Canopy
