RIN 2120-AA64
Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2013-07-09, which applies to certain The Boeing Company Model 737-700,
-700C, -800, and -900ER series airplanes, Model 747-400F series
airplanes, and Model 767-200 and -300 series airplanes. AD 2013-07-09
requires a general visual inspection for affected serial numbers of the
crew oxygen mask stowage box units, and replacement or re-
identification as necessary. Since the FAA issued AD 2013-07-09, the
agency has determined that the affected parts may be installed on
airplanes outside the original applicability of AD 2013-07-09. This
proposed AD would retain the requirements of AD 2013-07-09 and expand
the applicability to include those other airplanes. The FAA is
proposing this AD to address the unsafe condition on these products.
DATES: The FAA must receive comments on this proposed AD by August 9,
2019.

Discussion
The FAA issued AD 2013-07-09, Amendment 39-17413 (78 FR 22178,
April 15, 2013) (``AD 2013-07-09''), for certain The Boeing Company
Model 737-700, -700C, -800, and -900ER series airplanes, Model 747-400F
series airplanes, and Model 767-200 and -300
[[Page 29819]]
series airplanes. AD 2013-07-09 requires a general visual inspection
for affected serial numbers of the crew oxygen mask stowage box units,
and replacement or re-identification as necessary. AD 2013-07-09
resulted from reports indicating that certain crew oxygen mask stowage
box units were possibly delivered with a burr in the inlet fitting. The
burr might break loose during test or operation, and might pose an
ignition source or cause an inlet valve to jam. The FAA issued AD 2013-
07-09 to address this possible ignition source, which could result in
an oxygen-fed fire; or an inlet valve jam in a crew oxygen mask stowage
box unit, which could result in restricted flow of oxygen.
Actions Since AD 2013-07-09 Was Issued
Since the FAA issued AD 2013-07-09, it has been determined that the
affected parts may be installed as rotable spares on airplanes outside
of the applicability of AD 2013-07-09, thereby subjecting those
airplanes to the unsafe condition. Therefore, the applicability in this
proposed AD has been expanded to include all The Boeing Company Model
737-700, -700C, -800, and -900ER series airplanes, Model 747-400F
series airplanes, and Model 767-200 and -300 series airplanes.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Boeing Alert Service Bulletin 737-35A1121,
Revision 1, dated November 7, 2011; Boeing Alert Service Bulletin 747-
35A2126, Revision 1, dated September 29, 2011; Boeing Alert Service
Bulletin 767-35A0057, Revision 1, dated November 17, 2011; and
Intertechnique Service Bulletin MXP1/4-35-175, Revision 2, dated May
10, 2011; which the Director of the Federal Register approved for
incorporation by reference as of May 20, 2013 (78 FR 22178, April 15,
2013). This service information 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.
FAA's Determination
The FAA is proposing this AD because the FAA evaluated all the
relevant information and determined the unsafe condition described
previously is likely to exist or develop in other products of these
same type designs.
Proposed AD Requirements
This proposed AD would retain all requirements of AD 2013-07-09,
and expand the applicability to include all The Boeing Company Model
737-700, -700C, -800, and -900ER series airplanes, Model 747-400F
series airplanes, and Model 767-200 and -300 series airplanes. This
proposed AD would require accomplishing the actions specified in the
service information specified previously.
Costs of Compliance
The FAA estimates that this proposed AD affects 2,140 airplanes of
U.S. registry. The agency estimates the following costs to comply with
this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection (retained action from AD 1 work-hour x $85 per hour $0 $85 $3,400

airplanes).
Inspection (new action) (2,100 1 work-hour x $85 per hour 0 85 178,500
airplanes). = $85.
----------------------------------------------------------------------------------------------------------------
The FAA has received no definitive data that would enable the
agency to provide cost estimates for the on-condition actions specified
in this proposed AD.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, Section 106, describes the
authority of the FAA Administrator. Subtitle VII, Aviation Programs,
describes in more detail the scope of the Agency's authority.
The FAA is issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
This proposed AD is issued in accordance with authority delegated
by the Executive Director, Aircraft Certification Service, as
authorized by FAA Order 8000.51C. In accordance with that order,
issuance of ADs is normally a function of the Compliance and
Airworthiness Division, but during this transition period, the
Executive Director has delegated the authority to issue ADs applicable
to transport category airplanes and associated appliances to the
Director of the System Oversight Division.
Regulatory Findings
The FAA has determined that this proposed AD would not have
federalism implications under Executive Order 13132. This proposed AD
would not have a substantial direct effect on the States, on the
relationship between the national Government and the States, or on the
distribution of power and responsibilities among the various levels of
government.
For the reasons discussed above, I certify that the proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Will not affect intrastate aviation in Alaska, and
(3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
List of Subjects in 14 CFR Part 39

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD)
2013-07-09, Amendment 39-17413 (78
[[Page 29820]]
FR 22178, April 15, 2013), and adding the following new AD:
The Boeing Company: Docket No. FAA-2019-0480; Product Identifier
2019-NM-041-AD.
(a) Comments Due Date
The FAA must receive comments on this AD action by August 9,
2019.
(b) Affected ADs
This AD replaces AD 2013-07-09, Amendment 39-17413 (78 FR 22178,
April 15, 2013) (``AD 2013-07-09'').
(c) Applicability
This AD applies to all The Boeing Company airplanes,
certificated in any category, as identified in paragraphs (c)(1),
(c)(2), and (c)(3) of this AD.
(1) Model 737-700, -700C, -800, and -900ER series airplanes.
(2) Model 747-400F series airplanes.
(3) Model 767-200 and -300 series airplanes.
(d) Subject
Air Transport Association (ATA) of America Code 35, Oxygen.
(e) Unsafe Condition
This AD was prompted by reports indicating that certain crew
oxygen mask stowage box units were possibly delivered with a burr in
the inlet fitting. The burr might break loose during test or
operation, and might pose an ignition source or cause an inlet valve
to jam. We are issuing this AD to address this possible ignition
source, which could result in an oxygen-fed fire; or an inlet valve
jam in a crew oxygen mask stowage box unit, which could result in
restricted flow of oxygen.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
