No. But it is a convenient time to perform and track the ELT inspection.Are ELT inspections part of an annual inspection?
Yes.Must the ELT inspection be specifically mentioned in log books?
Yeah, I get that.Needs to be tested every 12 months.
If an inspection is required, it must be logged.Yeah, I get that.
What I want to know is if it needs a specific mention in logs

You will see an entry that says some like “inspected ELT in accordance with FAR 91.207(d)”
I was taught that testing is required and that the date of battery replacement is to be noted on the exterior of the unit. I log the ELT testing and the battery replacement date in my airframe logbook.
d) Each emergency locator transmitter required by paragraph (a) of this section must be inspected within 12 calendar months after the last inspection for -
(1) Proper installation;
(2) Battery corrosion;
(3) Operation of the controls and crash sensor; and
(4) The presence of a sufficient signal radiated from its antenna.
That’s the inspection.
Paragraph C is the batteries.
(c) Batteries used in the emergency locator transmitters required by paragraphs (a) and (b) of this section must be replaced (or recharged, if the batteries are rechargeable) -
(1) When the transmitter has been in use for more than 1 cumulative hour; or
(2) When 50 percent of their useful life (or, for rechargeable batteries, 50 percent of their useful life of charge) has expired, as established by the transmitter manufacturer under its approval.
The new expiration date for replacing (or recharging) the battery must be legibly marked on the outside of the transmitter and entered in the aircraft maintenance record. Paragraph (c)(2) of this section does not apply to batteries (such as water-activated batteries) that are essentially unaffected during probable storage intervals.
I have always wondered how 406 elts are tested; can no longer listen on our comm radios.
There's also this:I have always wondered how 406 elts are tested; can no longer listen on our comm radios.
I found this which talks about a test set. (it's an install AC so perhaps not completely applicable to the 12 mo test FAR)
AC91-44A
406 MHz Testing.
Except for the one which has a busted component on the 406 side.Every 406 I’ve seen also transmits on 121.5.

Then you hear 121.5 on the comm, thinking all is well - but it is not transmitting on 406.
