B/E Aerospace Protective Breathing Equipment Part Number 119003-11 and Part Number 119003-21
We are superseding Airworthiness Directive (AD) 2016-11-20 for certain B/E Aerospace protective breathing equipment (PBE) that is installed on airplanes. AD 2016-11-20 required replacing part number (P/N) 119003-11 PBE units. Since we issued AD 2016-11-20, we received a report that PBE units, P/N 119003-21, within a certain serial number range are made with candle tube material determined to have a low yield strength and may be volatile upon use or disposal. This AD retains the actions required in AD 2016-11-20 and requires inspecting and replacing P/N 119003-11 and 119003-21 PBE units. We are issuing this AD to address the unsafe condition on these products.

Ameri-King Corporation Emergency Locator Transmitters
We are adopting a new airworthiness directive (AD) for certain Ameri-King Corporation emergency locator transmitters (ELTs) as installed on various aircraft. This AD was prompted by multiple reports of ELT failure and a report of noncompliance to quality standards and manufacturer processes related to Ameri-King Corporation ELTs. This AD requires repetitive inspections of the ELT for discrepancies; repetitive checks, tests, and verifications, as applicable, to ensure the ELT is functioning; and corrective actions if necessary. This AD also allows for optional replacement of affected ELTs and, for certain aircraft, optional removal of affected ELTs. We are issuing this AD to address the unsafe condition on these products.
