The G-switch is designed to be checked during authorized maintenance to ensure that sudden deceleration will trigger the unit. 5. Technical Specifications of the ELT 96 Frequencies: 406 MHz (406.028 MHz) and 121.5 MHz. Power Output: 5 Watts (121.5 MHz) / 5 Watts (406 MHz). Battery Type: Lithium (High-temperature tolerance). Operating Temperature: -20°C to +55°C (typical). Transmission Time: 48 hours minimum at -20°C. 6. Regulatory Compliance
The unit should be inspected annually for corrosion, securely mounted, and ensure the antenna cable is intact.
If the unit is very old (discontinued), you may need to replace it with a current‑model ELT (e.g., Kannad, ARTEX, or ACK) since maintenance data for obsolete units is often withdrawn.
Ensure the master switch on the ELT body is set to the OFF or ARMED position (never leave it in the ON position during service). Air Precision Elt 96 Maintenance Manual
The Air Precision ELT 96 is designed to automatically transmit distress signals following an aircraft accident. It operates on standard aviation emergency frequencies to assist search and rescue (SAR) teams in locating the aircraft. Key Specifications
The is more than a collection of technical data—it is the definitive source for ensuring that when an aircraft goes down, the world will hear the alert. Skipping steps, guessing torque values, or ignoring battery expiration are risks no professional can afford.
Minimum 75 mW on both frequencies throughout the required operating duration. 2. Mandatory Maintenance Schedules The G-switch is designed to be checked during
While a direct PDF of the original Air Precision document is challenging to locate online due to the company's corporate evolution, the necessary instructions are embedded within two sources: (such as for the TB 20, Embraer EMB145, and Saab 340) and generic ELT testing guidelines .
The specifies that the following checks must be performed annually:
Verify the automatic sensor functions correctly using an authorized omnidirectional deceleration test rig. Power Output: 5 Watts (121
The unit features a built-in self-test function to verify the output power of the 406 MHz transmitter and battery capacity.
A built-in self-test should be conducted regularly (e.g., every 6 months) to verify that the unit's electronics are functional. This test must be performed only during the first 5 minutes of any hour to avoid false alarms.
: Operates on 121.5 MHz, 243 MHz (analog), and 406 MHz (digital). Power Output : Minimum 5W for the 406 MHz transmitter.
Maintenance personnel use the manual to verify compliance with the following technical standards:
