[PLEASE READ!] --> AnPMech-List message posted by: Matt Dralle Dear Listers, Some have asked, "What's my Contribution used for?", and this is certainly a valid question. Here are just a few examples of what your direct List support enables. It provides for the very expensive, business-class, high-speed T1 Internet connection used on the List, insuring maximum performance and minimal contention when accessing List services. It pays for the regular system hardware and software upgrades enabling the highest performance possible for services such as the Archive Search Engine and List Browser. It pays for 16+ years worth of online archive data available for instant random access. And, it offsets the many hours spent writing, developing, and maintaining the custom applications that power this List Service such as the List Browse, Search Engine, and PhotoShare. But most importantly, your List Contribution enables a forum where you and your peers can communicate freely in an environment that is free from moderation, censorship, advertising, commercialism, SPAM, and computer viruses. How many places on the Internet can you make all those statements about these days? I will venture to say - next to none... It is YOUR CONTRIBUTION that directly enables these many desirable aspects of this most valuable List service. Please support it today with your List Contribution. Its one of the best investments you can make in your Sport... List Contribution Web Site: http://www.matronics.com/contribution Thank you for your support!

Please pardon this intrusion. This note is not specific to your particular list, but regardless of what you are building, restoring, or flying, an issue exists that could potentially affect all of you who fly in the United States. That issue is the Washington DC ADIZ. This ADIZ was put into effect as a temporary protective measure for Washington DC airspace after 9/11. There is now an NPRM out to make this airspace *permanent*. The original comment period for this NPRM expired yesterday, November 2. However, the FAA has now extended the comment period for another 90 days, so if you did not get your comments in, HERE IS YOUR CHANCE! Information on the ADIZ, and why we are fighting it, can be found here: http://www.aopa.org/adizalert/ I live underneath the current DC ADIZ, so I get to play with this every time I fly. The AOPA page above gives a good summary of what has happened in this area since it's inception. Help on formulating comments for this NPRM can be found here: http://www.aopa.org/adizalert/help.html Comments on this NPRM can be submitted (online) to the DOT here: http://dms.dot.gov/submit/ Instructions on how to navigate and fill out the DOT page to submit your comments are available here: http://www.aopa.org/adizalert/faa_help.html There are over 18000 comments against this NPRM at this time. If yours is not one of them, please take the time now to submit your comments; every one helps. If this ADIZ becomes permanent, then there could be an ADIZ coming to an airspace near you in the future! I thank Matt for allowing me to send this to you. Even if you don't live near the DC area, please do what you can to protect your flying priviledges... submit your comments!

Anyway, I had asked the rep if the balancing of a prop that required say holes to be drilled in the spinner backing plate to add weights would be considered a minor or major alteration. He said that in his experience, it depends on what FSDO you are dealing with. One thing I have learned already is how inconsistent the Feds are!!!! I was just wondering what the experiences of you folks on the A&P list has been with regard to this? Thanks, Bill ________________________________ Message 4 _____________________________________ Time: 08:53:36 AM PST US From: "Mike Ferrer" Subject: Re: AnPMech-List: Vibration --> AnPMech-List message posted by: "Mike Ferrer" I have the ACES prop balancer and their FAA-approved manual requires a 337 if you add weight. From their manual... "Modification of the spinner bulkhead, either by drilling or adding weights in the form of nuts, bolts, washers, or any combination thereof, requires the completion of FAA Form 337 for return to service."

YES! Each FSDO has its own ... Let's call them uniquities. They are all familiar with prop balancing. So if all you put down in the 337 was, "Attached 8.5 Gram and 14.0 Gram respectively, balance weights at the 12 O'clock and 7 O'clock position on the geared flywheel." That would be enough. Since there was NO Fabrication and NO weighable amount of material removal it would be considered a MINOR Alteration. There are many circumstances where even a large amount of work is considered MINOR Alterations. Consider doing a reupholster job. That is minor. Barry "Chop'd Liver"
