Air Precision Elt 96 Maintenance Manual Jun 2026

Inspect the internal compartment for signs of battery acid leakage or corrosion. Clean the battery connector terminals using residue-free contact cleaner. Step 5: Installation

Replace battery pack; Check internal circuitry on a test bench. Crystal oscillator failure; Extreme temperature exposure. Recalibrate oscillator; Replace RF board if drift persists. False Activation Faulty G-switch; Short circuit in cockpit remote wiring.

In the world of aviation, few pieces of equipment carry as much literal weight in a life-or-death scenario as the Emergency Locator Transmitter (ELT). The has long been a staple in general aviation, known for its reliability and compliance with international distress frequency standards. However, an ELT is only as good as its maintenance history. A device that fires a 406 MHz signal to the Cospas-Sarsat satellite network on paper is useless if its batteries are expired, its antenna is corroded, or its G-switch is faulty.

Enumerates specific part numbers for screws, seals, antennas, and battery packs. 2. Required Tools and Test Equipment

The ELT 96 relies on high-energy to sustain its 48-hour output during extreme temperature swings. Air Precision Elt 96 Maintenance Manual

Check the battery compartment and connectors for signs of leakage or oxidation.

Manual cockpit/switch control or automatic visual G-switch mechanism.

The brand has a specific history that affects documentation. Air Precision was originally a French avionics company. In July 2001, Air Precision purchased the business rights of distress beacons from Socata. Later, the company was acquired and became part of Cobham France . Most recently (as of 2022), the company changed its name to Everaxis Aerospace & Defence , which has since surrendered some of the older ETSO authorizations for legacy products.

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. Inspect the internal compartment for signs of battery

The ELT 96 is a highly reliable safety device designed for fixed or portable emergency use within general aviation and commercial aircraft. It transmits distress signals across three vital emergency frequencies: .

The Air Precision Elt 96 uses a specific lithium battery pack. The date is printed clearly on the unit.

Remove the securing screws around the perimeter of the outer housing using the specified non-magnetic screwdriver. Crystal oscillator failure; Extreme temperature exposure

Switch the ELT switch (either on the unit or via the remote panel) to TEST or brief ON for a maximum of 3 seconds.

: The cockpit remote control unit and the main orange housing feature an LED indicator. The manual details specific flash patterns that identify low battery voltage, antenna VSWR mismatches, or internal circuit faults.

Insert the fresh battery pack and secure it with the retention bracket. Plug the battery harness into the motherboard circuit connector until it clicks into place. Step 6: Resealing the Unit

The battery pack must be replaced immediately upon meeting any of the following criteria: The manufacturer's printed expiration date is reached.

Because the unit contains lithium chemistry batteries, it is classified as Dangerous Goods Class 9 for air transport. Ensure compliant packaging, labeling, and documentation accompany the shipment.
