(formerly Scott Aviation) oxygen cylinder and valve assemblies, and oxygen valve assemblies, installed on but not limited to various transport airplanes.

AD 2023-13-11 also limited the installation of affected parts and required reporting inspection results and returning certain assemblies to the manufacturer.
