PERIODIC MAINTENANCE CHECK LIST
WITH COMPLIANCE CROSS REFERENCES
In the United States, minimum maintenance requirements for ELTs are stated in FAR
91.207 paragraph (d): Each emergency locator transmitter required by paragraph (a)
of this section must be inspected within 12 calendar months after the last inspection
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 components of the ELT.
In Canada, The periodicity of operational checks is at the operator's discretion, but the
check shall only be conducted during the first five minutes of any UTC.
NOTE 1: All references to maintenance requirements for the United States shall also
apply to all ELT users outside of the US unless otherwise required by the installer /
aircraft maintenance procedures or the relevant national regulations.
NOTE 2: Ameri-King suggests Functional Testing of the ELT every 1 to 2 months.
WARNING : Do not allow test duration to exceed 5 seconds. A false alarm may
be generated.
Any time the ELT is activated, it is transmitting a 121.5 MHz and 243.0 MHz distress
signal. If the ELT operates for approximately 50 seconds, a “live” 406 MHz distress
signal is transmitted and is considered valid by the Cospas-Sarsat satellite system.
Any time that the ELT Main Switch is lifted and flipped from “OFF” to “ARM”, a
406 MHz self test signal is transmitted (after 25 seconds), however it is specially
coded as a “self test” signal that is ignored by the COSPAS-SARSAT satellites.
