Hello Noel Loveys, Thank you for your inputs on this subject, but in the 

interest of stamping out hearsay, gossip, and rumors regarding experimental 

amateur built aircraft I'd like to point out that some of your comments are 

just not applicable in the USA.



The following statements that you wrote are not correct in the USA:



1) "In that case if even on an OBAM aircraft the ELT and transponder must be

installed or signed off by a certified AME (Canada) or A&P (U.S.)"



2) "One of the things I do not like about the new ELT is that aircraft 

cannot

borrow another ELT while one is out having scheduled service done."



3) "...so they wouldn't have to fly without one... Which is legal for up to 

90

days."



Note that the regulatory requirements for having an ELT in a US registered 

civil aircraft operating in the US, and the circumstances permitted for 

flying without an ELT installed, are contained in 14 CFR 91.207. That 

section is too long and complicated to be copied, or even extracted in this 

posting. It may be accessed here:

4) "In fact even a licensed AME is not allowed to change the batteries on an 

ELT

it has to be done by an approved Avionics tech or an approved avionics 

shop."



5) "Amateur built aircraft are another quintal of fish...  They don't even 

have

to carry an ELT."



They do in the USA in accordance with 14 CFR 91.207.



Thanks for your help in posting accuracy.

The minimum for use of ELTs is to demonstrate that the complete system meets

the TSO. Good luck with doing that with a roll your own antenna of unknown

impedance and SWR. ELTs and transponders are two items on OBAM aircraft that

must comply with the TSO.

It sure would be... but for amateur aircraft you might be able to use your

Have to look at your ELT installation instructions. The ELT is TSOed and

might require that you use their antenna.

Subject: RE: AeroElectric-List: ELT Antenna

In this  country any appliance on a certified aircraft with certain

exceptions has to be installed by or checked by a certified AME ( aircraft

maintenance engineer ) and the installation has to be documented in the

airframe log book and noted if there is a separate log book for the

appliance.

One of the things I do not like about the new ELT is that aircraft cannot

borrow another ELT while one is out having scheduled service done.  In the

past the AMO I worked for had a "loaner" ELT that we would put in aircraft

so they wouldn't have to fly without one... Which is legal for up to 90

days.

In fact even a licensed AME is not allowed to change the batteries on an ELT

it has to be done by an approved Avionics tech or an approved avionics shop.

Amateur built aircraft are another quintal of fish...  They don't even have

to carry an ELT.  Mind I don't know anyone who is stupid enough to fly this

land without one.

Hello Noel, Thank you for your most courteous reply. You wrote: "New 406 

mHz. ELTs are identified to specific aircraft in specific configuration."



This is a very important point that you make. Each of those ELT's is also 

identified to a specific Owner/Operator of that specific aircraft and to a 

specific Primary and Alternate 24-Hour Emergency Contact associated with 

that specific ELT and aircraft along with communication information for all 

of those individuals. See here:



http://www.nmea.org/Assets/elt%20406%20registration%20and%20renewal.pdf



The purpose of that contact information is to permit rapid communication 

with one of those individuals should an emergency signal be received by a 

satellite to confirm that the signal is not a false alarm.



Also note that it is possible on that form to submit a Change of ELT 

Information or Ownership and to do it fairly quickly online at:



www.beaconregistration.noaa.gov



This would permit a fairly flexible and timely means of swapping a 406 Mhz 

ELT from one aircraft to another if that became a need and one complied with 

all provisions of the registration requirements.

		   My apologies sometimes I forget that most people on the lists are not

 Canadian and there are several differences in our aviation procedures.



 In Canada an aircraft flown commercially must have an ELT on board. 

 However

 I'm not sure it has to be turned on.  An ELT may be removed for servicing

 for up to 90 days.



 New 406 mHz. ELTs are identified to specific aircraft in specific

 configuration.  One of the new ELT cannot be taken out of one aircraft and

 put in another.  The identifier code on the ELT is "Married "to a specific

 airplane.  My understanding is if a large plane is converted from 

 passenger

 to cargo it must be refitted with a new ELT as there is no vehicle to do

 this.



 I do like to keep up with what is going on south of the 49th so I will 

 have

 a look through your link and at the same time I'll have another look 

 through

 CARs, Canada's equivalent to FARs.



 Thank you.
