Airworthiness Directive coverage
FAA / EASA public regulatory data
- FAAAD 2024-19-15effective Nov 26, 2024Mixed actions
The FAA is correcting an airworthiness directive (AD) that was published in the Federal Register. That AD applies to certain Safran Aerosystems oxygen cylinder and valve assemblies, and oxygen valve assemblies, installed on but not limited to various transport airplanes. As published, the AD number of the AD being removed in the amendatory language of AD 2024-19-15 is incorrect, and the manufacturer name in the applicability and material required to be followed for identification of affected serial numbers in one location contains a typographical error. This document corrects those errors. In all other respects, the original document remains the same.
- FAAAD 2023-13-11effective Sep 5, 2023Prohibition
The FAA is superseding Airworthiness Directive (AD) 2022-04- 09, which applied to certain AVOX Systems Inc. (formerly Scott Aviation) oxygen cylinder and valve assemblies; and oxygen valve assemblies; installed on but not limited to various transport airplanes. AD 2022-04-09 required an inspection of the oxygen valve assemblies, and oxygen cylinder and valve assemblies, to determine the serial number; for certain assemblies and parts, a detailed inspection of the gap between the bottom of the packing retainer and top of the valve body on the assemblies; and replacement of assemblies having unacceptable gaps. This AD was prompted by a determination that additional assemblies and parts are affected by the unsafe condition. This AD requires an inspection of the oxygen valve assemblies, and oxygen cylinder and valve assemblies, to determine the serial number of the valve, cylinder, and entire assembly; for certain assemblies and parts, a detailed inspection for correct spacing of the gap between the bottom of the packing retainer and top of the valve body on the assemblies and replacement of assemblies having unacceptable gaps. This AD also limits the installation of affected parts under certain conditions and reporting inspection results and returning certain assemblies to the manufacturer. The FAA is issuing this AD to address the unsafe condition on these products.
- FAAAD 2022-04-09effective Apr 4, 2022Prohibition
The FAA is adopting a new airworthiness directive (AD) for certain AVOX System Inc. (formerly Scott Aviation) oxygen cylinder and valve assemblies, and oxygen valve assemblies, installed on but not limited to various transport airplanes. This AD was prompted by reports of cylinder and valve assemblies having oxygen leakage from the valve assembly vent hole, caused by the absence of a guide that maintains appropriate spacing between certain parts. This AD requires an inspection of the oxygen valve assemblies, and oxygen cylinder and valve assemblies, to determine the serial number of the valve, cylinder, and entire assembly. For assemblies and parts with certain serial numbers, this AD requires a detailed inspection for correct spacing of the gap between the bottom of the packing retainer and top of the valve body on the assemblies, and replacement of assemblies having unacceptable gaps. The FAA is issuing this AD to address the unsafe condition on these products.
Directives citing this part number in the FAA / EASA regulatory corpus we have processed — not a complete historical AD list. An AD is a compliance requirement that drives scheduled work (inspections, replacements, modifications) on the fleets that carry the part; a directive naming this PN as the replacement part is install demand, not an action against it — and none of this is a prediction that the part will fail.
