These are " horizontal stabilizer reinforcements"! These may help
hold the tail together should the AN 4 bolt ever break. These are CNC
cut and made from Stainless steel. They will bolt right on and are an
exact fit for the front and rear.. As you can see in the picture you
may have to relocate your Dorsal fin bracket down an inch. I recommend
these on older high time airframes. The Challenger is a solid aircraft
but AN bolts can, over time break due to being over-tightened. This
will not show up on a pre flight or an annual condition insp. This is 1
modification that may save your life! I will be selling them at $20
a pair, that will include shipping! Get your order in as soon as you
can and I will get a set sent off to you. Cash works but I can take a
check for the amount. just make your check out to Jim Robinson.
We have installed several sets on
Challengers, both single and the 2 place, here at Erie Airpark. Fly
safe! Jim Robinson.

There is a new breed of recreational airship taking flight on the
fringes of aviation. These blimps are intended for fun, not transport.
The key innovation: substituting hot air for helium or hydrogen as a
lifting gas. Hydrogen, the lightest element, is dangerously combustible.
Helium, though inert, is expensive. If an airship uses hot air, as
balloons do, you can just let the air escape at the end of each flight,
fold up the envelope and store it. "Here you have a corner of aviation
that has been dormant for decades, for generations. What we've come up
with is a disruptive technology."
