| Subject: | Cowling Update. Horizontal braces |
Well folks, we're getting there. We met with the FAA last Friday.
I'll need to do the carb heat rise test. I also need to do a dive
test. I need to dive the plane to 220 mph. Should be an interesting
flight test. We were going to use the DERs Mooney as a chase plane,
but, the Tiger has a higher Vne. Weird huh. Now, we have to find
another plane, and I have to pay the pilot to fly a chase plane during
the dive. I have a stock Tiger instrumented and will be doing some
flight tests tomorrow. One of the costs projected for the installation
that I hadn't considered earlier is the cost of the baffles. They are
turning out to be higher than I thought. The installation instructions
are 29 pages so far. But, then, the FAA hasn't had a chance to look at
them yet. $10,000+ and counting . . . . .
I have also hired a structural engineer to come up with a fix for the
horizontal braces. Unlike the current fix which just replaces the
bent/cracked parts with the same parts, this is a whole new
installation. I am also looking into a metal-to-metal bonding
procedure that is more like the original structure and doesn't use fuel
tank sealant as an adhesive. I'm going for an STC for a permanent fix,
just in case I need to fix my plane some day. $4000+ and counting . .

Gary, what kind of schedule would you be on for the test flights? I might
be able to chase you a few times depending on when. I'm having some work
done to my plane later this month/early October but after that maybe? If
the amount of time you need is modest I'm probably available at little to no
cost too:)
My Vne is 204 kt. which I'd think would do it. Vno is 166 and Va is 140
FWIW.
Glad to hear progress is being made.
Jamey
