AD NUMBER: 2014-17-02

PRODUCT: Certain Honeywell ASCa Inc. emergency locator transmitters (ELTs) installed on various transport category airplanes.
ACTION: Final rule; request for comments.

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2013-18-09 for the product listed above. 2013-18-09 required various one-time general visual inspections of the ELT transmitter units (TUs), and corrective actions if necessary.

This new AD corrects the manufacturer's name in the AD applicability and adds a source of approval for an installation. AD 2013-18-09 was prompted by a fire on a parked and unoccupied airplane; preliminary information indicated combustion in the area of the ELT TU. This new AD was prompted by the identification of an error in the applicability of AD 2013-18-09.

The FAA is issuing this AD to detect and correct discrepancies of the battery wiring installation inside the TU, which could result in an electrical short and possible ignition source.

DATES: This AD becomes effective September 9, 2014. Comments must be received by October 9, 2014.
