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
making many times but it sounds like it is your DER that is making the
decision as to whether another cooling test should be run or not.
Doesn't he have the authority to make such a decision based on the facts
and info available?

The alternator on a Jaguar is open like it was on a Traveler. I have
holes 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
changed 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
hotter 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
holes 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 strut) 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
with AA5Bs. But, then, with the funky inlet, who'd want to? Right?
