Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A300 F4-605R airplanes and Model A310-324 airplanes. This proposed AD was prompted by a report that certain emergency locator transmitter (ELT) lithium batteries lack protection against current injection. This proposed AD would require modification of the airplane circuit connecting the ELT battery, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
