This just in from the FAA - looks specific to one size but might merit investigation. SUBJ: Landing Gear, Tire Tube. Goodyear Aviation Tires, Flight Mate Butyl SAIB: CE-11-47R1 Inner Tube, 7.00-8.00-6. Date: January 30, 2012 This is information only. Recommendations aren’t mandatory. Introduction This Special Airworthiness Information Bulletin (SAIB) alerts operators, pilots, and aircraft manufacturers of possible inner tube failures made from butyl rubber by Goodyear Aviation Tires, (Goodyear) . At this time, the failure of the inner tubes is not an unsafe condition that would warrant airworthiness directive (AD) action under Title 14 of the Code of Federal Aviation Regulations (14 CFR) part 39. The SAIB has been revised to incorporate updated information from Goodyear and highlight inner tube failures are not limited to only cold weather operations. Background There have been several reports of Goodyear inner tubes failures during cold weather operations. The failures were reported following short flights or following ground operations. Goodyear is aware of these failures and has made several attempts to improve the cold weather performance of its inner tubes. In November 2008, Goodyear incorporated a change to its compound for their butyl rubber inner tubes. Since then, the reliability of the inner tubes had increased, but cold weather failures were still reported. Therefore, Goodyear has started to test another improvement to their butyl rubber inner tubes made from an updated compound. Following successful field testing, Goodyear will make the improved inner tubes available. Goodyear inner tube failures are not limited to only cold weather operations, additional failures have been reported. Goodyear is aware of the issues from the field and began an improvement program to investigate and improve the inner tubes. A flex crack was occasionally observed on the natural fold from the extrusion process during manufacturing. The compound was modified to reduce the impact of extrusion, optimize splicing pressure and improve flex which should improve crack resistance. Additionally cold temperature properties of the tube were improved to further enhance performance for cold temperature operations. Inner tubes were produced with the improved compound and field tested with positive results. As of August 15, 2011 the production has been changed over to the modified compound for 5.00-5 inner tubes. Recommendations The FAA recommends you provide special attention during pre-flight to airplane tires with Goodyear butyl rubber inner tubes by: Checking to ensure that all tires are properly inflated and are holding pressure; Being prepared to compensate for a flat tire during landing as this might pull the airplane to the affected side; and Providing extra awareness during cross wind landing conditions on narrow and on short runways.

Quote: Bnicolette For my weight and balance, I have been using the fltplan.com version and have made a couple "canned" versions that I keep in my clipboard can that represent most of my flights. Full fuel, 1 pax, full fuel 2 pax, 50 gallons/1pax, etc. That way I have most of my configurations covered and current in the event of a ramp check since everything is on my iPhone these days.

Great timing @RETIRED-SOME posted what looks to be your exact issue on another thread - check his link Mike Re: Teflon hose life Posted Jan 25, 2012 11:58 AM Wow,,,what a lot of conversation on gyro instrument hoses. I helped fix a problem with a mooney a few years ago and was surprised at what i found. My find, with photos, is located at the "FAQ Section' of our web site www.AerotechComponents.com , under the sentenance that starts out witn... "I Own A 1999....." If anyone out there has photos of information on this type of problem,,,let me know,,,, we'll add them to the FAQ section of our site and hopefully help someone out in the future. « Last edit: Jan 25, 2012 12:12 PM by RETIRED-SOME»

All I know is that I warm the oil up before putting it in - pours faster that way. And I prefer colder fuel to warmer when delivered - you get more in a gallon that way.

I read that as well - google search turned this up http://www.ntsb.gov/aviationquery/brief2.aspx?ev_id=20091114X32349&ntsbno=ERA10FA062&akey=1 a Piper PA-28R-200

Quote: devildog I just bought my 1968 M-20-F six months ago and am about to spend a bundle on panel upgrade. I paid the $9,000 deposit and am on the list for the new Avidyne IFD540 gps. The local A&I will be installing that and a new JPI Fuel Flow monitor, JPI EDM 700 engine monitor and an HSI. I do not have the cash for a new HSI and am looking for a recently rebuilt or overhauled non-slaved EDM360A. I will be removing the current llMorrow flybuddy gps and one of my King KX55 and CDI indicators to make room for the new Avidyne IFD540. Please respond if you have one or know of a good price on one. So far the best price I found was at Bennett Avionics for $3,500

I've been toying with the idea of elimnating the three individual covers and going with a single piece across the cowl - any thoughts?

I sump all three - first thing on preflight is the gasolator I'm in there lowering the flaps anyway - by the time I'm done with the rest its all evaporated. The wing sumps don't give me enough to pour back in.

Smiles - it's all relative - I spent about 6 hours toll - two cans of abs cement and some fiberglass and four cans of interior plastic paint - You can't tell where the cracks were. The repairs are made on the back side of the plastic, unless you are missing big chunks I definitely recommend it.

Do a search on the forum for ABS - that is the interior plastic - many of us have had success in repairing and refurbishing our plastics if you don't want to go the replacement route.

Don't know his price but here is an example http://cgi.ebay.com/ebaymotors/1967-Mooney-M20F-Executive-?cmd=ViewItem&item=200703383205 Radios could be better.

There is no difference in the oxygen - here's a interesting read on a home fill solution as well.. http://www.avweb.com/news/pelican/182079-1.html

LOL - all fun n games till someone gets pissed.

.... I didn't see Nazi ....

Well you were partly there in removing the plastic from above - the cable is likely broken at the control arm - the left vent in front will give you access to the mechaism and cable - but to get to it you have to pull off the duct tape covering the many little screws - I pulled both front vents when I did mine.

Quote: rogrbal My M20F has overhead fresh air vents from air scoop door on top of aircraft. The air scoop open and shut control knob on aircraft overhead does not control scoop door when turned. I have to manually open and shut the door when preflighting / post flighting. The question is how do I fix the problem? It was not evident / obvious how to get at the control when I took the plastic interior ceiling down. Has the wire going to the vent broken? or is it slipping? How do I get to the inside of the flat vent tubing to fix the problem? Thanks for the help. rogrbal@gmail.com

Gear down - portable com you'll kinda look like a piper and still beat the 172 there. Just don't go over Vle

Although there's a full blown compressor where I share space I have one of the basic plug it in the cigarette lighter compressors available at any auto store, or Harbor Freight

I've been looking into oxygen systems as well but will be going for individual bottles in lieu of a single. the D bottle is 13 cubic feet and will provide 14 man hours as opposed to 24 cubic ft and 26 man hours for an E bottle. Benefits are individual adjustment of flow per person - you can bring or leave behind a bottle or two. You can get four individual bottle, regulator and oxymizer cannulas from a medical outlet for far less than a single bottle four place setup from aerox or nelson or skyox.
