Removing old antennas

Kage,

I do agree with you about it being ignored. Alot of pilots/owners are
not aware of this loophole. In fact, AOPA I believe,or maybe it was
Aircraft technician, Did an article on this very same subject. What
gets most people is that the equipment was deactivated and every thing
is fine but they fail to make a logbook entry noting the deactivated
equipment was in fact inspected.

As for your comments infering that because an A&P works on A Piper
Arrow, he is a shade tree mechanic....well it's just an assholic
comment.I have seen outstanding single engine mechanics.

By the way, I have been working on GII, GIII, GIV for about 20 yrs.
Have done engine changes, 72 month inspections..just about
everything....And Yes, I have left SAV. with properly deactivated
equip....

Dream on mamma,

Say what you want. Like I said, it is generally ignored by shade tree
mechanics working on Piper Arrows. But if you bring your Gulfstream into a
legitimate shop your inoperative equipment WILL be repaired, replaced,
removed or required inspections performed and the equipment returned to
service.

Jay,

You have no choice. You are REQUIRED to remove inoperative equipment.
Part
91.405 (c).

Best,
Karl.

BTW, the reg says the equipment must be repaired, replaced, removed or
inspected at the next required inspection. What they mean by "inspected"
is
if a required inspection is due. Not just the mechanic peering at a
piece of
inop equipment and letting it go for another year! This rule is
regularily
ignored by the GA community. But it would never fly at a reputable
repair
facility. Once the antennas are removed you will have to revise the
equipment list and weight and balance.

WRONG!!!!!
91.405(c)
each owner operator blah blah blah (c)shall have any inoperative
instrument or item of equipment permitted to be blah blah blah.
Inspected means. You have that piece of equipment inspected to be
sure it is still deactivated.

For an example: Say I have a Piper Arrow with inop air conditioning.
I can deactivate and placard that system. Never have it fixed. As long
as. At the next required inspection.(IE 100 hr or annual), I inspect
it to make sure it is still deactivated and placarded AND Make a
logbook entry of such.

Good to go till next inspection....

Of course, Joe, I said that tongue in cheek, knowing it would get a rise.
This IS Usenet! One must keep the standards up.

I guess the point is that one can find some scum bag mechanic to sign off on
anything. Just like you can find some "assholic" pilot to fly that same
airplane away. My own mechanic was charging $35/hr. five years ago. He was
always complaining about the way he was treated by his customers.They always
wanted something for nothing, for him to sign off on questionable items,
borrowing his tools, borrowing his hangar, questioning his knowledge about
airworthy parts, showing him how to "correctly" do his job.....etc, etc.

I seriously urged him to raise his rates, which he did, in several increases
over the years. He is now at $95/hr. He is still busy. But, ALL of the
freeloaders have gone away. Plus, he has time for his own projects that make
him far more money than doing annuals. I am now suggesting to him that $105
sounds somehow psychologically lower than $95. I want him to stay in the
business and be comfortable. His knowledge of my airplane is exceptional and
his basement is full of new parts from his old, closed, large shop, from
which he too, escaped.

Congratulations on escaping SAV.

Karl

I cannot speak to your airframe. When we did the calcs on Voyager, we figured
we added roughly half a knot for each antenna we put inside the fuselage. I'd
probably guess about the same for you.

Worth the bother? Perhaps. Surely makes a cleaner looking airplane, even WITH
the scab patches over the old antenna holes (painted to match, of course).

"Scab patches"? I just bought one of the little 99 cent steel hole plugs
at Coast to Coast Aerospace, when I pulled the LORAN antenna off the Fly
Baby.... :-)

Wouldn't a steel plug used in an aluminum base be a potential source
of galvanic corrosion?
Hope there's plenty of paint between the dissimilar metals and better
yet, that the plugs are made of stainless steel or, at least, have
been passivated.

It probably would, if the darn plug would just stay in. :-)

We're coming up on our annual inspection in May, and there are at least four
antennas on our bird that do nothing. I'll bet there's a few feet of cable
going to each one, too.

Does removing an antenna net you any extra speed, or is it mainly a weight
reduction thing?



It depends on the location -- antennae on the top of the fuselage or
ahead of the windshield are in the highest-drag places and may give you
a knot.

Another effect to consider is that, (even unused) antennae may affect
radio transmission coverage. they can resonate with your transmitter and
cause distortions and scalloped radiation patterns.

Advice: get rid of unused antennae!

You will probably gain 1-2mph for removing all 4 antennas.

My question: What are the antennas?

My question: What are the antennas?

A previous owner (2 owners ago, a guy I know well) had installed a complete
glass panel -- one of the first anyone had seen.

Well, okay, it wasn't a "complete" glass panel, like the new Garmin G1000,
but it was as close as you could get five years ago. Multi-function
display, up-linked weather, the whole nine yards.

When he bought his awesome Comanche 400, he took all those goodies with
him... :-(

In typical aviation fashion, the shop disconnected the wires and left the
antennas.

So, on top I've got an Apollo antenna (GPS, I presume), and two Com antennas
that appear to go no where. On the bottom I've got several unidentified
antennas that can probably go, too.

I'll have to dig around some more at the annual to see what goes where.

If the Apollo antenna looks like a comm antenna, then it's probably an
Apollo loran antenna. A GPS antenna would look like a thin disk. One
thing you might want to consider is keeping one of the extra comm antennas
and use it for your handheld comm. In an emergency, it would work a lot
better than the rubber duck. I keep meaning to install the extra comm
antenna I bought years ago, for that purpose.
