4. Maintenance

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 United States, 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 corros on; i

(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 installat on 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 condition, insecure

mounting, and improper operat on.

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 “Self-test” section.
