4.1 Periodic Maintenance for the United States

Artex suggests testing of the ELT every 1 to 2 months. This provides an indication of the integrity of the ELT and antenna system. If performed at this rate, the accumulated operating time will not reduce the 6-year life rating of the battery pack.
In the US, minimum maintenance requirements for ELTs are stated in FAR 91.207 paragraph (d):
(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 corroson;

(3) Operation of the controls and crash sensor; and

(4) The presence of a sufficient signal radiated from its antenna.

To ensure continued reliability and airworthiness, your ELT must be inspected for damage and wear caused by age, exposed elements, vibration, etc. Inspections are also to take place annually per FAR Part 91.409. FAR 43, Appendix D(i) states in part that each person performing an annual or 100-hour inspection shall inspect the following components of (the ELT):
(1) (ELT unit and mount) for improper installation and insecure mounting.

(2) Wiring and conduits - for improper routing, insecure mounting, and obvious defects.

(3) Bonding and shielding - for improper installation and poor condition.

(4) Antenna, including trailing antenna - for poor conditon, insecure mounting, and improper operaton.

All testing of the ELT referenced in this section may be performed by limiting the transmission of the ELT to 3 sweeps of the 121.5 MHz audio tone. Only transmit within the first 5 minutes after the hour or as specified by local or national regulations. See paragraph 4.4.9 “Self-Test” section.
4.2 Canadian Maintenance Requirements

4.2.1 Regulations

Canadian Aviation Regulations Part V, Chapter 571, appendix G spells out maintenance requirements for ELT use in Canada.   The complete text is available at: http://www.tc.gc.ca/CivilAviation/Regserv/Affairs/cars/Part5/Standards/a571sg.htm 
Maintenance steps for Canada include:
. Corrosion Inspection - (Refer to paragraph 4.4.3)

. Operational Testing – (Refer to paragraph 4.4.9)

. Performance Testing – (Refer to paragraph 4.2.2)

. Battery Replacement and Recharging – (Refer to paragraphs. 4.4.4 and 4.4.5)

. The battery pack is NOT rechargeable.  The reference to recharging in the Canadian regulation is NOT applicable to Artex, Inc. products.

. The battery pack must be replaced if a seven flash error occurs when the ELT is set to “ARM”.

. Shipping Instructions – (Refer to paragraph 4.4.14)

A complete maintenance program must be part of the annual checks for the aircraft.  Artex, Inc. encourages aircraft users to perform simple checks including steps in paragraphs 4.4.1 to 4.4.3, 4.4.6 and 4.4.7 on a monthly basis.
