Periodic Maintenance for ME406/406HM ELT for the US
In the United States, minimum maintenance requirements for ELTs are stated in FAR 91.207 para-
graph (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 corrosion
3) Operation of the controls and crash sensor
4) The presence of a sufficient signal radiated from its antenna
NOTE: All references to maintenance requirements for the United States shall also apply to all ELT
users outside of the United States unless otherwise required by the installer/aircraft maintenance
procedures or the relevant national regulations.
ELT manufacturer 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 5-year life rating of the battery pack.
ELT Battery removal:
CAUTION: The battery pack contains electrostatic sensitive parts. Take ESD precautions before
handling. Damage may happen to the exposed electric parts and prevent correct operation of the
ELT. Refer to ELT Description, Operation, Installation and Maintenance Manual p/n 570-1600, Rev.
E or later, Para. 5.1 for methods of preventing an EletroStatic Discharge
Remove the 8 securing screws from the battery-side cover. Battery pack is identified by the
1)
embossed text: "BATTERY ACCESS ON THIS SIDE".
2) Carefully lift the battery cover (battery pack) away from the ELT and unplug the flex-cable con-
nected to the pack. Do not pull on the flexible portion of the cable - use the rigid section of the
flex circuit at the connector as a handle.
3) Inspect the battery pack and ELT chassis. The battery cells, components and connectors
should be free of corrosion. Inspect flex-circuit for broken connections or damage. Ensure
the battery housing is free of cracks or other visible damage.
