He has done a lot of modified alternators and thinks he can by-pass any testing based on his data and the previous flight test data. Keep your fingers crossed. -----Original Message----- From: flyv35b Sent: Wed, Apr 7, 2010 6:29 am Subject: Re: TeamGrumman-List: AG5B and the Jaguar cowling Gary, I didn't realize that was the case with your baffling. That sounds like a welcome improvement for accessibility to the alternator. I realize that logic does not play an important role in their decision mak ing many times but it sounds like it is your DER that is making the decisi on as to whether another cooling test should be run or not. Doesn't he ha ve the authority to make such a decision based on the facts and info avail able?

I have ho les in the cabin heat duct that vent directly on the alternator. During tests, the alternator was a little warmer, but not by enough to make a difference. Cliff, it's the FAA. Logic does not come into the picture. -----Original Message----- From: flyv35b Sent: Tue, Apr 6, 2010 2:24 pm Subject: Re: TeamGrumman-List: AG5B and the Jaguar cowling What makes them think it would run hotter just because it's 24 volts? Also, It's on the cold side of the baffle and shouldn't see much engine or exhaust heat. No real difference from an AA-5B is there? Cliff ----- Original Message ----- From: teamgrumman@aol.com Sent: Tuesday, April 06, 2010 10:08 AM Subject: Re: TeamGrumman-List: AG5B and the Jaguar cowling So, I talked to the DER about the AG5B and my cowling. All was going pretty well until he asked what else, besides the air box, was change d in the AG5B. I told him, "They made it 24 volts." So, the FAA may want a climb cooling test to see if the alternator on an AG5B runs ho tter than an AA5B. What a pain in the ass. -----Original Message----- From: teamgrumman@AOL.COM Sent: Mon, Apr 5, 2010 12:41 pm Subject: TeamGrumman-List: AG5B and the Jaguar cowling Here is something I ran into last night. The bottom cowling attach ho les on the late model (Tiger LLC) Tigers do not have the same spacing as real Tigers. For some reason, the spacing is changed by 1/8 inch on the outboard holes (the bottom corners and the holes near the stru t) and as much as 1/2 inch for the holes between them. What a waste of engineering. Not only that, but, that means the cowlings are not interchangeable wi th AA5Bs. But, then, with the funky inlet, who'd want to? Right? ator?TeamGrumman-List">http://www.matronics.com/Navigator?TeamGrumman-List ttp://forums.matronics.com ibution">http://www.matronics.com/contribution href="http://www.matronics.com/Navigator?TeamGrumman-List">http://www.ma tronics.com/Navigator?TeamGrumman-List href="http://forums.matronics.com">http://forums.matronics.com href="http://www.matronics.com/contribution">http://www.matronics.com/c ator?TeamGrumman-List">http://www.matronics.com/Navigator?TeamGrumman-List ttp://forums.matronics.com ibution">http://www.matronics.com/contribution href="http://www.matronics.com/Navigator?TeamGrumman-List">http://www.ma tronics.com/Navigator?TeamGrumman-List href="http://forums.matronics.com">http://forums.matronics.com href="http://www.matronics.com/contribution">http://www.matronics.com/c ======================== =========== ======================== =========== ======================== =========== ======================== =========== ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message teamgrumman-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/TeamGrumman-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/teamgrumman-list Browse Digests http://www.matronics.com/digest/teamgrumman-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
