ELT installation

[astjp2]

Re: ELT installation

I used to sell airplane parts in Anchorage about 10 years ago and we brought in the Ameri-king elt's because of the D battery option....and they were JUNK, every one that we had in stock had cracks around the screw holes. An FAA inspector from FSDO had bought one for his personal airplane and he brought it back because the advertised voice transmit capability did not work. After trying 4 more, we gave him his money back. You get what you pay for when it comes to ELT's. The D batteries used must also have the manufacturers expiration date to be useable.....If you are doing a new installation, you MUST have the remote capability to turn it on. Whether its with the switch or the ELT itsself. Another little side note, if you install it, you now have to test the structure for the mount to make sure that it does not deflect the airframe more than .030" with about 100lbs of static pressure. My numbers maybe wrong but I think that I am in the right ballpark. There is also a stipulation that it cannot be mounted to the fuselage skin. We had this training in the IA seminar last march from the Fairbanks FSDO.

here is a link for the FAA's powerpoint presentation....

Buy the smallest cheapest one you can find see attached picture

That ELT can not be installed in a new installation. It doesn't meet the current TSO. I don't think that the installation would be approved on a 337 under present standards. I'm not a big fan of the Ameriking ELT either, but have had good luck with the ACK brand. It also uses D cell alkaline batteries. Tom

I have heard this before. But why are they still being sold new if that is the case?

From the EBC website."The EBC 102A met or exceeded the requirements of FAA TSO C-91 and is FCC Type Accepted under Part 87".

From the CFR's.

(1) There is attached to the airplane an approved automatic type emergency locator transmitter that is in operable condition for the following operations, except that after June 21, 1995, an emergency locator transmitter that meets the requirements of TSO-C91 may not be used for new installations:

Replacing the ELT with one of the same type would not be a new installation. New installations require a TSO-C91a ELT. I might have copies of ICA's and 337 for an ACK installation in a T-craft, if I can get them off my old computer. Tom

If it is documented that there was the same make/model installed before a certain date, then a new one can be installed if the old one dies, just had my PMI look at mine and ask about it. long ago, like 1978 there was a 337 filled out, fortunitly, luckily (where is the speel checkeer heer?) for me, O.T.

Re: ELT installation

Well, I guess that leaves me out because my airplane has never had an ELT installed in its life.

OK, I looked up the reg and here is how I see it. The reg mentions TSO-C91 as mentioned. But the EBC-502, which is the one I am looking at is certified under TSO-C91a, as mentioned. So as I see it, I would be ok to mount one of those. I saw an airplane that was built in 2004 with one in it, so I know it has to be legit.

The EBC-502 is OK, but the picture shown earlier was the EBC-102a. From the picture that was shown the mounting did not look like it would pass for a new installation either. Tom

Re: ELT installation

Mine looks like this. Installation is per part 43.
