6 PERIODIC MAINTENANCE (INSTRUCTIONS FOR CONTINUED AIRWORTHINESS):
REFERENCES: FAR Part 91.207, Part 43 Appendix D (i).
FAR Part 91.207 Paragraph (d) FAR Part 91.407
PURPOSE:
To insure continued reliability of your ELT, it must be inspected for damage and wear
which could be caused by age, exposed elements, vibrations, etc. Even the best designed equipment, if not properly
maintained and cared for, will eventually fail.
IMPORTANT NOTES:
The following inspections must be performed, a minimum of one time every year:
6.1
Secure Inspection: Inspect the ELT Main Unit and Mounting Tray to insure all fasteners and mechanical
assemblies are secure.
6.2
Corrosion Inspection for Coaxial Cable: Inspect the Coaxial Cable connecting the ELT Main Unit to the
Antenna for cuts or abrasions on its outer jacket. Disconnect the BNC connectors on each end. Examine both the
BNC connectors and the mating plug on the Antenna and the ELT Main Unit for any signs of corrosion.
6.3
Corrosion Inspection for Remote Wiring Modular Cable: Inspect the Remote Wiring Modular Cable,
connecting the ELT Main Unit to the Remote Unit of signs of wear or abrasion on its outer jacket. Remove the
Modular Connecting Cable and inspect and jack and plug assembly for corrosion.
6.4
Expiration Date Check: Check the expiration date of the ELT Main Unit and the Remote Unit Batteries.
Replace if necessary.
6.5 Battery Leakage Check: Remove the Battery Case and inspect the Battery Compartment for signs of
corrosion or battery leakage. If any battery leakage is present, all batteries must be replaced. The Battery useful life
is 5 years.
6.6 G-Switch Check: Ensure that the Main Switch on the ELT main unit must be selected at “ARM: position at all
times. Activate the ELT using applied force. The direction for mounting and force activation is indicated on the
ELT. The AK-451- (AF)(AP) ELT can be activated by using a rapid forward (throwing) motion coupled by a rapid
reversing action. Verify that the ELT has been activated by use of the Wattmeter, the Airplane’s VHF Radio
Communications Receiver when tuned to
121.5 MHz, or other means (see Note 1). The ELT must then be reset by pressing either the RESET push button
located on the ELT main unit or the ELT Remote Unit.
Note 1:
This is not a measured check. It only indicates that the G-Switch is working.
6.7 Antenna Check: A low quality AM Broadcast Radio Receiver or Equivalent Test Equipment should be
used to determine if energy is being transmitted from the Antenna. When the Antenna of this Radio (tuning dial on
any setting) is held about 6 inches from the activated ELT Antenna, the ELT Aural tone will be heard (see notes 2
and 3). The ELT must be reset by pressing either the RESET push button located on the ELT Main unit or the ELT
Remote Unit.
Note 2:
This is not a measured check, but it does provide confidence that the Antenna is radiating with sufficient power to
aid search and rescue. The Aircraft’s VHF Receiver, tuned to 121.5 MHz, may also be used. This Receiver
however is more sensitive and could pick up a weak signal even if the radiating ELT’s Antenna is disconnected.
Thus, it does not check the integrity of the ELT System or provide the same level of confidence as does an AM
Radio.
Note 3:
Because the ELT radiates on the emergency frequency, the Federal Communications Commission allows these tests
to be conducted only within the first 5 minutes after any hour.
IMPORTANT NOTE:
IN NORMAL CONFIGURATION, THE MAIN SWITCH, LOCATED ON THE
ELT MAIN UNIT, MUST BE SELECTED AT “ARM” POSITION AT ALL TIMES.
