Hi Dennis,
If you have a pair of the crimpers shown in the attached (poorly focused)
photos, they can be modified to crimp the flag type terminals that you have.
I used a Dremel tool to create a centred groove in the tip as shown in the
photo. I then used a small diameter chain saw file to finish out the groove
to a good diameter (radius) for crimping flags.
I got the crimper tool from Cleaveland Tools for $12.00 a few years ago.
I hope the photos give enough info. If not email me for more info.

Good Morning All,
I haven't followed this subject thoroughly, but in the messages I have
monitored, I have seen no mention of the FARs pertinent to logging flight time.
The following is from ancient memory, please feel free to shoot it full of
holes!
My recollection is that a pilot is ALLOWED to log as pilot flight time that
time from when the aircraft moves under it's own power for the purpose of
flight until the time the aircraft is parked following the flight.
No flight time may be logged if no flight occurs, yet if you taxi out for
takeoff, encounter extensive ground delays, make a fifteen minute flight around
the pattern, decide to give it up and return to the hangar, it may take as
long as an hour or more all of which can be logged as pilot flight time.
On the other hand, you are REQUIRED to log engine and airframe time of
flight for maintenance purposes.
That has been defined by the FAA as from lift off to touch down.
Taxi time, runups and maintenance checks need not be counted as operational
time for maintenance purposes
No mechanical or electrical device is required to be available to record
either type of time.
A written log maintained by the operator is fine for all.
The FAA does allow a recording tachometer to be used as a substitute for
manually logging the time.
Other methods of logging airframe and engine time have been accepted by the
FAA such as the use of strut switches on airplanes and switches on the
collective for helicopters.
Whatever you use as a substitute for a written log is up to you, the
operator. The only FAA requirement that I recall is that the data be recorded in
some acceptable manner. What is acceptable is to be determined at the hearing!
Does that not jibe with the group's interpretation of the pertinent FARs?
Happy Skies,

I like simplicity. I use Hobbs time for everything. That includes
maintenance cycles for changing oil. If I change it a bit early as compared
to tach time, I should be helping my engine live longer. Idle time
particularly for warm up is important especially in the winter months. I
would not think it would be good to just act as if it did not matter.
However, it is a good idea to use a consistent time system so I don't
disagree with your approach.

Bob & Listers,
I'd be VERY leary about bidding on the item below. The seller wants
payment only by Western Union. This is the classic ploy of a rip off artist
who has high jacked the ligitemite account of an honest EBay seller. Any
time you see payment only by Western Union, be suspicious. Ask the seller
some questions. Ask if you can come over to see the item in person. If it's
a scammer, he'll dodge and hedge.

Listers,
I may have been premature with my last post. I note that the seller will
also accept PayPal and major credit cards, so this may well be a legitimate
auction. However, as an EBay member who has recently had his own account
high jacked, I'm very leery of auctions where Western Union is offered.
Other scam tip offs are a willingness to sell world wide and a very
attractive shipping policy.
When an account is high jacked, the EBay member who's account is used,
has no idea that the items (which will be vapor ware) have been listed to
his account.

I'm concerned you view "worldwide" as a negative. As a frequent ebay purchaser
from the UK, it is always a frustration that many ebay sellers won't ship outside
of the US even though the process is both easy and cheap.
I do agree that "Western Union" is the big red flag. In general I will only buy
using paypal even if it means up-ing the price to cover the costs.
Best Regards
Peter

This is most likely an RFI problem. The transponder talks
to the ground in a stream of short (.5 uS) pulses that
encode your squawk and altitude. While average power from the
transponder is low (well under 1W) the peak power can be 100W
or more.
I'd look for bad connector in transponder coax that may be
radiating the interior of the aircraft. Is this a new condition
or has it existed since day-one for the installation? You
might need to reposition the transponder antenna. Check it's
installation too. Dismount, clean the bonding areas under the
mounting hardware and re-install.

I usually offer shipping to Canada, Mexico and Western Europe when I sell
items on EBay. Like I said, I'm suspicious of items offered "world wide".

How about some of you XC bike riders out there? I haven't researched it, but
I see a lot of bikes with intercoms between pilot & pax, complete with sound
systems and I'd imagine CB radio, etc. I'd imagine good protection at a
lower cost than "aviation" stuff, just like anything else........

I've ridden Goldwings for years and have used the headset/mic units.
They should work, but I'm not so sure they would be any cheaper than a/c

Keep in mind a couple of thoughts.......
This material could very well work in the GA impact applications "most of
the time", but, I am guessing that 3M does not see a market large enough to
commit to the testing and paper work hassles that they would have to work
through. Also, I am assuming that these are "films" of some type and I
would venture to guess that they do not have the ability to be applied to
all the compound curves in our various windows and canopies designs.

On my comant WSI/GPS antenna, they answered my question
more than once about grounds. They said it does not
require a ground plane, but it does require a ground. It needs
to have a ground on the screws at least, just to allow the
active circuitry voltages to power the thing. Other than
that, nothing.

It is obvious3M want nothing to do with any such practice, purely for the
litigation inferred. As for compatibility, I suspect you just buy some and
try it out. I would rather lose ten bucks than my eyesight - might even
stick it on my visor too.

Cheers,
I have one of these very useful devices, because I won it at a
Hamfest (Not a swine convention but a glorified flea market for radio nuts).
I gave it to the local club as there is no way an expensive item such as
this would be used monthly, except antenna labs.
However, in spite of all kinds of warnings, even dedicated hams
burnt the device out, at $50 a pop for commercial repair. SO I keep it, but
will serve to test any antenna in the club. That way it won't become a
charred mote in the back storage.
I say again, try the local ham club (www.ARRL.org) and look for
"Affliliated clubs". Send them an email, or phone and explain your desparate
need. You may have to turn away an army of curious............ but one will
have an antenna analyzer.

Subject: | Battery options? |
--> AeroElectric-List message posted by: "Alan K. Adamson" <aadamson@highrf.com>
Curious of some opinions. I have a Lancair Legacy that is going to be a 24V
dual alt/batt setup. I have the following options for batteries and I'm not
sure which is the most preferred.
A) use 2 full size 24v Concorde batteries, each around 17ah. This creates a
size and weight challenge
B) use 1 full size 24v Concorde and 1 7.2ah backup B&C 24v battery, this
cuts the weight down, but at the expense of less than 2/3s the capacity on
the backup side
C) a derivative of number 1 is to use 1 fullsize 24v concorde and 2 odyssey
type 12v batteries in parallel for the backup side. I'm not sure of the
weight penalty here, but I get better backup current capacity. I believe
that 2 can fit in the same size as 1 24v concorde so battery boxes are not
the issue.
Thots... I suppose I'm borrowing trouble as my wife would say. A backup
battery is just that, scale what's on it for the 7.2ah B&C, use the smaller
size and be done with it....
But I just had to ask,
Alan

That's a LOT of backup....Why do you think you need that much?
Personally I would have the two alts and stick with a single
battery....With a decent load you could still run your alternator
without the bettery if it somehow failed.

Stan,
I use the SL-30 intercom and it's acceptable with my Bose and David Clark headsets.
Doesn't work at all well with the LightSpeed ANR headset that my buddy
has though.
Someone mentioned that it's tough to control volume and squelch. True because
those items are buried a few menu levels "down" from the main screen.
There is no music function and no muting function.
I eventually plan to get an intercom.

Listers,
Is anyone with the Garmin SL-30 nav-comm using the built-in intercom?
If so, is it acceptable? Or do you recommend buying a separate intercom?
Is squelch a problem? Do you have control over squelch? Is there a means to
input music? Is there a muting function?
All advice appreciated.

Dale,
The relay you mention is actually a Ford starter relay. S stands for
START and I stands for IGNITION BYPASS. To engage the relay, you need to
apply 14 volts to the S terminal. For our use, the I terminal isn't needed.
However, you could run a 22 AWG wire from the I terminal up to a "starter
engaged" enunciator lamp on the instrument panel. Run the other lead from
this lamp to your single point ground block. The lamp would warn you if the
relay ever stuck "on".

Subject: | Deer Strike Incident |
--> AeroElectric-List message posted by: <bakerocb@cox.net>
1/30/2006
Hello Fellow Pilots, To expand on the subject of striking animal objects.
A few years back I was involved in a deer strike in a rented Cessna 172
during take off roll while making a touch and go landing at a hard surface,
public use, non controlled field . In my opinion the incident could not have
been avoided. The results were:
1) I was asked to submit a written report to the local FAA FSDO which I did.
2) I had to write a check for $1,000 for the insurance deductible that I was
responsible for. The renting agency had actually raised the deductible
obligation to $5,000, but had neglected to tell me that or have me sign the
new rental agreement to that effect so I convinced them that $1,000 was all
that I owed them.
3) Damage to the aircraft was not that extensive and there was no evidence
of propeller contact at all. But the person who owned the aircraft and had
leased it to the renting agency saw this as an opportunity to have the
engine overhauled at the insurance company's expense. The engine was removed
and shipped back to Lycoming for tear down and rework. The final cost to the
insurance company for airplane repair and engine removal, rework, and
reinstallation was over $11,000 -- I don't know how much over.
4) For the next 3 or 5 years, depending upon which insurance company I
applied to for liability insurance coverage only for my amateur built
experimental airplane, I was refused coverage because of this incident. Some
of the insurance agents cared absolutely nothing about the nature of the
incident, my contribution towards its cause, or the resulting cost, and
refused coverage over the telephone simply because the incident was on my
record.
My recommendations: Don't hit anything. Think long and hard about who you
tell about what you hit.

And when you're reincarnated, don't do something stupid like coming back as

When I was building my slider, I bought some nice weatherstripping from some
outfit, high quality stuff with 3M adhesive etc.. They typically sell only
wholesale, so my "business" was aircraft building. About 4 years later, I
got a letter from the company saying that, unfortunately, they would not be
able to sell to me anymore, being that their new policy prevented use in
airplanes. I admired their recordkeeping.
In a democracy, we get the government we deserve.

Hamfests are a term for amateur operators getting together to swap and
sell surplus equipment. They tend to pick up frequency in February
through June timeline.
Do follow the recommendation to reach out to your local guys. HRO (Ham

However, in spite of all kinds of warnings, even dedicated
hams
burnt the device out, at $50 a pop for commercial repair. SO I keep it,
but
will serve to test any antenna in the club. That way it won't become a
charred mote in the back storage.
I say again, try the local ham club (www.ARRL.org) and look
for
"Affliliated clubs". Send them an email, or phone and explain your
desparate
need. You may have to turn away an army of curious............ but one
will
have an antenna analyzer.

Bob,
Thanks so much for making a personal response!
The condition did not seem to be a problem early in the airplane's
life, but got progressively worse, and then I had the transponder
checked and replaced. Since the cavity was bad, I convinced myself
that maybe the old cavity was spewing electromagnetic radiation
across the spectrum, thereby clobbering my receiver. However,
the problem occasionally returned, and this last weekend was
particularly bad.
I took a look at all the connectors and mounts before, but will do
so again. Actually the first time I had this problem I thought that
the colocated antenna cable runs of the VHF and transponder might
be the problem, . . .
I've never seen two coaxes "talk" to each other if they were
properly installed . . .
. . . and I "re-plumbed" quite a bit of the system to move them apart.
This effort included replacing most of the connectors, none of which had
any effect. Is there an easy way to check connectors or mounts with
a scope?
No, a pretty sophisticated thing called a network analyzer is needed.
If you've recently refurbished the connectors, then this is a very
low order probability. Let's call the coaxes and connectors 'good'.
I've had others tell me that they do not think this is RFI, but rather
the result of the transponder transient injecting some bad stuff onto
either the +14 vdc or the ground circuits of either the radio or the
audio panel. One gent told me he had a similar problem which he believed
was the result of his switching regulator putting trash on the power
line as it tried to deal with the transponder power surge. He said he
put a choke on his audio panel power supply to solve the problem. I'm
now thinking that one of the things I should have checked was whether
the interference only occurs during VHF transmissions, or alternately
clobbers my intercom as well. Maybe any audio would be getting clobbered,
not just VHF, and I only correlated it with VHF reception because
that's the only time my audio was keyed/de-squelched. Might be getting in
through the microphone circuit?
Get a couple of 6v lantern batteries and rig yourself a 12v "test"
battery. Try running the transponder from this battery by disconnecting
the power wire at the bus breaker and clip-leading the battery into the
system. If the noise goes away, then it's conducted onto the 14V line.
If this is the case, filtering at the source is better than filtering
at the victim.
Noted today that The Technician's Notebook by Jerry Gordon lists a service
bulletin KT-76-1 that talks about replacing the power supply inverter
transformer in order to reduce the electromagnetic radiation from the
transponder power supply. I would think that any service bulletin would
have been completed on the rebuilt transponder that I purchased just last
year, but this might be a clue.
Hmmmmm . . . I'm having trouble figuring out how this transformer
would go bad and get worse over time.
Thanks again for all the great advice! Just ordered a new copy of the
"Connection".... the one I have now is #6 or so, and I'm sure there's
a lot more good info in it by now!
Be sure to keep it up to date by downloading revisions from
the website as they are published. You only need to buy the
book once that way!
Check out chapter 16 on noise. I speak of the test battery
technique for powering either victims or antagonists from
the battery to see if observed effects change or go away.
The same chapter speaks of the value of isolating headset
and microphone jacks from airframe ground and carrying their
respective ground leads all the way back to the intercom on
shields or conductors in the bundles.
Be sure to let us know what you find!
