The Air Precision Elt 96 is a three-frequency emergency locator transmitter (ELT) that operates on 121.5, 243 and 406 MHz frequencies. It is designed to transmit a distress signal in case of an aircraft accident, and help the search and rescue teams locate the survivors. The ELT 96 can be installed as an automatic fixed (AF) or automatic portable (AP) device, depending on the aircraft type and configuration.
Air Precision Elt 96 Maintenance Manual
As a critical safety equipment, the ELT 96 requires regular maintenance and testing to ensure its proper functioning and reliability. This article will provide you with a comprehensive maintenance manual for the ELT 96, covering the following topics:
How to perform a self-test on the ELT 96
How to program the identification signal of the ELT 96
How to replace the battery of the ELT 96
How to troubleshoot common problems of the ELT 96
How to Perform a Self-Test on the ELT 96
The ELT 96 has a built-in self-test function that allows you to check the transmitter output power, the battery capacity, and the digital message format. The self-test should be performed at least once a month, or before each flight, according to the manufacturer's recommendations.
To perform a self-test on the ELT 96, follow these steps:
Locate the remote control unit of the ELT 96 in the cockpit.
Press and hold the TEST button for about two seconds. The LED indicator should flash green once.
Release the TEST button and wait for about five seconds. The LED indicator should flash green twice.
If the LED indicator flashes red instead of green, it means that there is a problem with the ELT 96. Refer to the troubleshooting section for more details.
How to Program the Identification Signal of the ELT 96
The ELT 96 transmits a digital message on 406 MHz frequency that contains information such as country ID code, aircraft registration, and serial number. This message helps to identify the source of the distress signal and avoid false alarms. The message can be programmed by using an external programming tool that connects to the ELT 96.
To program the identification signal of the ELT 96, follow these steps:
Obtain the programming tool from Air Precision or an authorized dealer. The part number is ELT 96 A 98 00 000.
Connect the programming tool to the data port of the ELT 96. Make sure that the power switch of the ELT 96 is in OFF position.
Turn on the programming tool and follow the instructions on its display. You will need to enter some data such as country ID code, aircraft registration, serial number, etc.
When you are done, turn off the programming tool and disconnect it from the ELT 96. Perform a self-test to verify that the message has been programmed correctly.
How to Replace
How to Replace the Battery of the ELT 96
The ELT 96 uses a lithium/thionyl chloride battery that provides a minimum of 48 hours of transmission at 5W PERP on 406 MHz frequency. The battery has a shelf life of 10 years and an operational life of 5 years. The battery should be replaced before its expiration date, or whenever the self-test indicates a low battery condition.
To replace the battery of the ELT 96, follow these steps:
Turn off the power switch of the ELT 96 and disconnect it from the aircraft power supply.
Remove the ELT 96 from its mounting bracket and place it on a flat surface.
Unscrew the four screws on the bottom cover of the ELT 96 and remove the cover.
Disconnect the battery connector from the circuit board and remove the old battery.
Insert a new battery with the same part number (ELT 96 A 2560 000 001) and connect it to the circuit board.
Replace the bottom cover and secure it with the four screws.
Reinstall the ELT 96 on its mounting bracket and reconnect it to the aircraft power supply.
Perform a self-test to verify that the new battery is working properly.
How to Troubleshoot Common Problems of the ELT 96
The ELT 96 is designed to be reliable and durable, but sometimes it may encounter some problems that affect its performance. Here are some common problems and their possible solutions:
The LED indicator flashes red during self-test. This means that there is a problem with the transmitter output power, the battery capacity, or the digital message format. Check the following:
Make sure that the antenna is properly connected and not damaged.
Make sure that the battery is not expired or low.
Make sure that the identification signal is programmed correctly.
The LED indicator does not flash at all during self-test. This means that there is no power to the ELT 96. Check the following:
Make sure that the power switch of the ELT 96 is in ON position.
Make sure that the aircraft power supply is working and connected to the ELT 96.
Make sure that
How to Activate and Deactivate the ELT 96
The ELT 96 can be activated automatically or manually, depending on the situation. The ELT 96 can also be deactivated if the distress signal is no longer needed or if it was triggered accidentally.
To activate and deactivate the ELT 96, follow these instructions:
Automatic activation: The ELT 96 has a shock crash sensor (G-switch) that detects an impact force of more than 2.3 G and triggers the transmitter automatically. The ELT 96 will start transmitting on all three frequencies (121.5, 243 and 406 MHz) within 50 seconds after the impact. The LED indicator on the remote control unit will flash red to indicate that the ELT 96 is activated.
Manual activation: The ELT 96 can also be activated manually by using the remote control unit in the cockpit. To activate the ELT 96 manually, press and hold the ON button for about two seconds. The LED indicator will flash red to indicate that the ELT 96 is activated.
Deactivation: The ELT 96 can be deactivated by using the remote control unit in the cockpit. To deactivate the ELT 96, press and hold the OFF button for about two seconds. The LED indicator will stop flashing and turn off to indicate that the ELT 96 is deactivated.
Note: The ELT 96 should only be deactivated if the distress signal is no longer needed or if it was triggered accidentally. If you deactivate the ELT 96 while in distress, you may jeopardize your chances of being rescued.
