We're 'negotiating' right now. 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.

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?

The alternator on a Jaguar is open like it was on a Traveler. 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.

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?

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.

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?
