It is highly recommended to check the digital format on the initial installation of the unit. This
is done with the use of a WST or equivalent tester. There are no requirements for annual retest
of this information.
7.9 Antenna Test
It is highly recommended to check the antenna for proper operation on the initial installation of
the unit. This is done with the use of a WST or equivalent tester. There are no requirements for
annual retest of this information.
As part of the annual type inspection:
•
Ensure that the antenna is securely fastened to the aircraft
•
Check for cracks or abrasions in the surface of the antenna
•
Ensure the antenna has proper sealing around the base to skin
•
Ensure that coaxes are properly secured with strain-relief provided
•
Ensure that coaxes are not interfering with any moving parts
7.10 G-Switch Check
Emerging Lifesaving Technologies provide instructions to activate the G-Switch for test
purposes. A rapid forward motion that comes to an abrupt stop (football pass method) will
usually set off the G-switch. The antenna must be installed during this procedure. The unit will
go into fault mode as indicated by rapid green light on the unit if it is activated with a 50 ohm
load applied or an antenna installed. Always check to insure the green light comes on and then
reset the unit within 30 seconds of the test. These or any other method approved by the local
aviation governing authority is acceptable.
7.11 Records Keeping
ICA that is performed on US registered aircraft is required to be annotated in the permanent
records of the aircraft. The annual check should be incorporated into the annual-type inspection
and include reference to 91.207d. It is not required to annotate the bi-monthly inspection.
