The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2016–9189; Directorate Identifier 2016–NM–114–AD] RIN 2120–AA64 Airworthiness Directives; The Boeing Company Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737–600, –700, –700C, –800, –900, and –900ER series airplanes. This proposed AD was prompted by reports of passenger service units (PSUs) becoming detached from the supporting airplane structure in several Model 737 airplane incidents that exceeded the design emergency load requirements for the PSUs. This proposed AD would require modifying the PSUs and life vest panels by removing the existing inboard lanyard and installing two new lanyards on the outboard edge of the PSUs and life vest panels. We are proposing this AD to prevent PSUs and life vest panels from detaching from the supporting airplane structure, which could lead to passenger injuries and impede passenger and crew egress during evacuation. DATES: We must receive comments on this proposed AD by November 28, 2016. SUMMARY: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov.

Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA– 2016–9189; Directorate Identifier 2016– NM–114–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments. We will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion We have received reports of PSUs becoming detached from the supporting airplane structure in several Model 737 airplane incidents that exceeded the design emergency load requirements for the PSUs. These incidents resulted in injuries to passengers’ faces and heads, which may have occurred when the PSUs became dislodged and encroached into the passengers’ occupiable space. Additionally, many of the PSUs above aisle seats that separated from their overhead bins were found in the cabin aisle. Such an obstruction in the rows and aisles, especially at overwing emergency exits, could delay emergency evacuation for passengers and crew. Detached PSUs and life vest panels, if not corrected, could result in passenger injuries and impede passenger and crew egress during evacuation. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Service Bulletin 737–25–1707, dated September 24, 2015. The service information describes procedures for modifying the PSUs and life vest panels by removing the existing inboard lanyard and installing two new lanyards on the outboard edge of the PSUs and life vest panels. 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 We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and 
-900ER series airplanes. This proposed AD was prompted by reports of 
passenger service units (PSUs) becoming detached from the supporting 
airplane structure in several Model 737 airplane incidents that 
exceeded the design emergency load requirements for the PSUs. This 
proposed AD would require modifying the PSUs and life vest panels by 
removing the existing inboard lanyard and installing two new lanyards 
on the outboard edge of the PSUs and life vest panels. We are proposing 
this AD to prevent PSUs and life vest panels from detaching from the 
supporting airplane structure, which could lead to passenger injuries 
and impede passenger and crew egress during evacuation.

DATES: We must receive comments on this proposed AD by November 28, 
2016.

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

Discussion

    We have received reports of PSUs becoming detached from the 
supporting airplane structure in several Model 737 airplane incidents 
that exceeded the design emergency load requirements for the PSUs. 
These incidents resulted in injuries to passengers' faces and heads, 
which may have occurred when the PSUs became dislodged and encroached 
into the passengers' occupiable space. Additionally, many of the PSUs 
above aisle seats that separated from their overhead bins were found in 
the cabin aisle. Such an obstruction in the rows and aisles, especially 
at overwing emergency exits, could delay emergency evacuation for 
passengers and crew. Detached PSUs and life vest panels, if not 
corrected, could result in passenger injuries and impede passenger and 
crew egress during evacuation.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Service Bulletin 737-25-1707, dated September 
24, 2015. The service information describes procedures for modifying 
the PSUs and life vest panels by removing the existing inboard lanyard 
and installing two new lanyards on the outboard edge of the PSUs and 
life vest panels. 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

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

[[Page 70648]]

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously. For information on the 
procedures and compliance times, see this service information at https://www.regulations.gov by searching for and locating Docket No. FAA-2016-
9189.

Costs of Compliance

    We estimate that this proposed AD affects 1,087 airplanes of U.S. 
registry. We estimate the following costs to comply with 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.
    We are 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.

Regulatory Findings

    We 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979),

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 adding the following new airworthiness 
directive (AD):

The Boeing Company: Docket No. FAA-2016-9189; Directorate Identifier 
2016-NM-114-AD.

(a) Comments Due Date

    We must receive comments by November 28, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to the Boeing Company Model 737-600, -700, -
700C, -800, -900, and -900ER series airplanes, certificated in any 
category, as identified in Boeing Service Bulletin 737-25-1707, 
dated September 24, 2015.

(d) Subject

    Air Transport Association (ATA) of America Code 25; Equipment/
furnishings.

(e) Unsafe Condition

    This AD was prompted by reports of passenger service units 
(PSUs) becoming detached from the supporting airplane structure in 
several Model 737 airplane incidents that exceeded the design 
emergency load requirements. We are issuing this AD to prevent PSUs 
and life vest panels from detaching from the supporting airplane 
structure, which could lead to passenger injuries and impede 
passenger and crew egress during evacuation.

(f) Compliance

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

(g) Installation

    Within 60 months after the effective date of this AD: Do the 
applicable actions required in paragraphs (g)(1) and (g)(2) of this 
AD, in accordance with the Accomplishment Instructions of Boeing 
Service Bulletin 737-25-1707, dated September 24, 2015.
    (1) For all airplanes: Remove the existing lanyard and install 
new lanyard assemblies in the PSUs.
    (2) For Group 2 airplanes, as identified in Boeing Service 
Bulletin 737-25-1707, dated September 24, 2015: Remove the existing 
lanyard and install new lanyard assemblies in the life vest panels.

(h) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle Aircraft Certification Office (ACO), 
FAA, has the authority to approve AMOCs for this AD, if requested 
using the procedures found in 14 CFR 39.19. In accordance with 14 
CFR 39.19, send your request to your principal inspector or local 
Flight Standards District Office, as appropriate. If sending 
information directly to the manager of the ACO, send it to the 
attention of the person identified in paragraph (i)(1) of this AD. 
Information may be emailed to: 9-ANM-Seattle-ACO-AMOC-Requests@faa.gov.
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair, modification, or alteration required by this AD 
if it is approved by the Boeing Commercial Airplanes Organization 
Designation Authorization (ODA) that has been authorized by the 
Manager, Seattle ACO, to make those findings. To be approved, the 
repair method, modification deviation, or alteration deviation must 
meet the certification basis of the airplane, and the approval must 
specifically refer to this AD.
    (4) For service information that contains steps that are labeled 
as Required for Compliance (RC), the provisions of paragraphs 
(h)(4)(i) and (h)(4)(ii) of this AD apply.
    (i) The steps labeled as RC, including substeps under an RC step 
and any figures

[[Page 70649]]

identified in an RC step, must be done to comply with the AD. If a 
step or substep is labeled ``RC Exempt,'' then the RC requirement is 
removed from that step or substep. An AMOC is required for any 
deviations to RC steps, including substeps and identified figures.
    (ii) Steps not labeled as RC may be deviated from using accepted 
methods in accordance with the operator's maintenance or inspection 
program without obtaining approval of an AMOC, provided the RC 
steps, including substeps and identified figures, can still be done 
as specified, and the airplane can be put back in an airworthy 
condition.
