Systems Inc.; Scott Aviation) Oxygen Cylinder and Valve Assemblies, and 
Oxygen Valve Assemblies

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; correction.

-----------------------------------------------------------------------

SUMMARY: 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.

DATES: This correction is effective November 26, 2024. The effective 
date of AD 2024-19-15 remains November 26, 2024.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 26, 
2024 (89 FR 84267, October 22, 2024).

SUPPLEMENTARY INFORMATION:

Background

    AD 2024-19-15, Amendment 39-22857 (89 FR 84267, October 22, 2024) 
(AD 2024-19-15), requires inspecting the oxygen valve assemblies, and 
oxygen cylinder and valve assemblies, to determine the serial number of 
the valve, cylinder, and entire assembly; inspecting certain assemblies 
and parts for correct spacing of the gap between the bottom of the 
packing retainer and top of the valve body on the assemblies, and 
replacing assemblies having unacceptable gaps; limits the installation 
of affected parts; and requires reporting inspection results and 
returning certain assemblies to the manufacturer. This AD applies to 
certain Safran Aerosystems oxygen cylinder and valve assemblies, and 
oxygen valve assemblies, installed on but not limited to various 
transport airplanes.

Need for Correction

    As published, the AD number of the AD being removed in the 
amendatory language of AD 2024-19-15 is incorrect. Paragraph 2.a. of 
the amendatory language refers to ``AD 2013-13-11.'' The correct AD 
reference is ``AD 2023-13-11.''
    Also as published, the manufacturer name in the introductory text 
of paragraph (c) in the regulatory text of AD 2024-19-15 contains a 
typographical error. The correct manufacturer name is ``Safran 
Aerosystems.''
    Also as published, the manufacturer name in the material identified 
in the text of paragraph (l)(1) in the regulatory text of AD 2024-19-15 
contains a typographical error. The correct manufacturer name is 
``Safran Aerosystems.''

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed the following material. This material specifies 
procedures for an inspection to determine the serial numbers of the 
oxygen cylinder and valve assemblies, and the oxygen valve assemblies, 
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, 
parts marking, inspection report, and return of parts to the 
manufacturer. These documents are distinct since they apply to 
different assembly part numbers.

    This material is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section.

Correction of Publication

    This document corrects three errors and correctly adds the AD as an 
amendment to 14 CFR 39.13. Although no other part of the preamble or 
regulatory information has been corrected, the FAA is publishing the 
entire rule in the Federal Register.
    The effective date of this AD remains November 26, 2024.
    Since this action only corrects an incorrect AD number and two 
typographical errors, it has no adverse economic impact and imposes no 
additional burden on any person. Therefore, the FAA has determined that 
notice and public comment procedures are unnecessary.

List of Subjects in 14 CFR Part 39

(d) Subject

    Air Transport Association (ATA) of America Code 35, Oxygen.

(e) Unsafe Condition

    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, and by the manufacturer identifying additional 
assemblies and parts affected by the unsafe condition. The FAA is 
issuing this AD to address oxygen leakage from cylinder and valve 
assemblies. The unsafe condition, if not addressed, could result in 
decreased or insufficient oxygen supply during a depressurization 
event; and heating or flow friction, which could cause an ignition 
event in the valve assembly.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Retained Definition of Detailed Inspection, With No Changes

    This paragraph restates the requirements of paragraph (g) of AD 
2023-13-11, with no changes. For the purposes of this AD, a detailed 
inspection is an intensive examination of a specific item, 
installation, or assembly to detect damage, failure, or 
irregularity. Available lighting is normally supplemented with a 
direct source of good lighting at an intensity deemed appropriate. 
Inspection aids such as mirror, magnifying lenses, etc., may be 
necessary. Surface cleaning and elaborate procedures may be 
required.

(h) Retained Identification of Affected Cylinder and Valve Assemblies, 
With Updated Language

    This paragraph restates the requirements of paragraph (h) of AD 
2023-13-11, with updated language. Within 60 days after September 5, 
2023 (the effective date of AD 2023-13-11), inspect the oxygen valve 
assemblies, and oxygen cylinder and valve assemblies, to determine 
if the serial numbers of the valve, cylinder, and entire assembly, 
are listed in Appendix 1 or Appendix 2, ``Affected Shipments,'' of 
the applicable material identified in paragraphs (h)(1) through (3) 
of this AD. A review of airplane maintenance records is acceptable 
in lieu of this inspection if the serial numbers can be conclusively 
determined from that review.
