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 E:\FR\FM\25JNP1.SGM 25JNP1 29819 Federal Register / Vol. 84, No. 122 / Tuesday, June 25, 2019 / Proposed Rules 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 Inspection (retained action from AD 2013-07-09) (40 airplanes). Inspection (new action) (2,100 airplanes) ...... 1 work-hour × $85 per hour = $85 ................. $0 $85 $3,400 1 work-hour × $85 per hour = $85 ................. 0 85 178,500 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. VerDate Sep<11>2014 20:41 Jun 24, 2019 Jkt 247001 Parts cost Cost on U.S. operators Labor cost The FAA has received no definitive data that would enable the agency to provide cost estimates for the oncondition actions specified in this proposed AD. khammond on DSKBBV9HB2PROD with PROPOSALS Cost per product 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, PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 (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 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2.

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.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

SUPPLEMENTARY INFORMATION:

Comments Invited

    The FAA invites you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under the ADDRESSES section. Include ``Docket No. FAA-2019-0480; 
Product Identifier 2019-NM-041-AD'' at the beginning of your comments. 
The agency specifically invites comments on the overall regulatory, 
economic, environmental, and energy aspects of this NPRM. The agency

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

 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

(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.
