Company Model 737 airplanes. AD
2012–19–11 currently requires
incorporating design changes to
improve the reliability of the cabin
altitude warning system by installing a
redundant cabin altitude pressure
switch, replacing the aural warning
module (AWM) with a new or reworked
AWM, and changing certain wire
bundles or connecting certain
previously capped and stowed wires as
necessary. For certain airplanes, AD
2012–19–11 also requires prior or
concurrent incorporation of related
design changes by modifying the
instrument panels, installing light
assemblies, modifying the wire bundles,
and installing a new circuit breaker, as
necessary. Since we issued AD 2012–
19–11, we have determined that certain
airplanes were not included in the
requirement to incorporate related
design changes. This proposed AD
would add, for certain airplanes, a
requirement to incorporate related
design changes. This proposed AD also,
for certain airplanes, no longer gives
credit for accomplishing certain
previous actions. We are proposing this
AD to prevent the loss of cabin altitude
warning, which could delay flightcrew
recognition of a lack of cabin
pressurization, and could result in
incapacitation of the flightcrew due to
hypoxia (a lack of oxygen in the body),
and consequent loss of control of the
airplane.
DATES: We must receive comments on
this proposed AD by September 12,
2014.

Discussion
On September 19, 2012, we issued AD
2012–19–11, Amendment 39–17206 (77
FR 60296, October 3, 2012), for certain
The Boeing Company Model 737
airplanes. AD 2012–19–11 requires
incorporating design changes to
improve the reliability of the cabin
altitude warning system by installing a
redundant cabin altitude pressure
switch, replacing the AWM with a new
or reworked AWM, and changing
VerDate Mar<15>2010

Jkt 232001
certain wire bundles or connecting
certain previously capped and stowed
wires as necessary. For certain
airplanes, AD 2012–19–11 also requires
prior or concurrent incorporation of
related design changes by modifying the
instrument panels, installing light
assemblies, modifying the wire bundles,
and installing a new circuit breaker, as
necessary. AD 2012–19–11 resulted
from a report of a flightcrew not
receiving an aural warning during a lack
of cabin pressurization event. We issued
AD 2012–19–11 to prevent the loss of
cabin altitude warning, which could
delay flightcrew recognition of a lack of
cabin pressurization, and could result in
incapacitation of the flightcrew due to
hypoxia (a lack of oxygen in the body),
and consequent loss of control of the
airplane.
Other Related Rulemaking
The concurrent actions for AD 2012–
19–11, Amendment 39–17206 (77 FR
60296, October 3, 2012), are the primary
corrective actions for AD 2011–03–14,
Amendment 39–16598 (76 FR 6529,
February 7, 2011), and AD 2013–02–05,
Amendment 39–17326 (78 FR 6202,
January 30, 2013). AD 2011–03–14 and
AD 2013–02–05 provide the necessary
wiring configuration to perform the
corrective actions for AD 2012–19–11.
AD 2011–03–14 (for certain Model 737–
100, –200, –200C, –300, –400, and –500
series airplanes) and AD 2013–02–05
(for certain Model 737–600, –700,
–700C, –800, –900, and –900ER series
airplanes) were issued to prevent failure
of the flightcrew to recognize and react
to a valid cabin altitude warning horn,
which could result in incapacitation of
the flightcrew due to hypoxia (a lack of
oxygen in the body), and consequent
loss of control of the airplane.
Actions Since AD 2012–19–11,
Amendment 39–17206 (77 FR 60296,
October 3, 2012), Was Issued
Since we issued AD 2012–19–11,
Amendment 39–17206 (77 FR 60296,
October 3, 2012), we have reviewed new
service information for the actions
required by paragraph (g) of AD 2012–
19–11, which refers to Boeing Special
Attention Service Bulletin 737–21–
1164, Revision 1, dated May 17, 2012,
as one of the appropriate sources of
service information. Boeing Special
Attention Service Bulletin 737–21–
1164, Revision 2, dated August 23,
2013, provides essentially the same
procedure for accomplishing the
actions, except for certain airplanes,
Boeing Special Attention Service
Bulletin 737–21–1164, Revision 2, dated
August 23, 2013, specifies to contact the
PO 00000
Frm 00016
Fmt 4702

manufacturer for the installation and
replacement of certain wire bundles.
We also have reviewed new service
information for the concurrent actions
required by paragraph (h) of AD 2012–
19–11, Amendment 39–17206 (77 FR
60296, October 3, 2012), which refers to
Boeing Alert Service Bulletin 737–
31A1325, dated January 11, 2010; and
Boeing Alert Service Bulletin 737–
31A1332, Revision 3, dated March 28,
2012; as the appropriate sources of
service information. Boeing Alert
Service Bulletin 737–31A1325, Revision
1, dated July 5, 2012; and Boeing Alert
Service Bulletin 737–31A1332, Revision
4, dated October 31, 2013; provide
essentially the same procedures for
accomplishing the concurrent actions,
except, for certain airplanes, Boeing
Alert Service Bulletin 737–31A1325,
Revision 1, dated July 5, 2012, specifies
to contact the manufacturer for
modification, installation, and repair
instructions. Boeing Alert Service
Bulletin 737–31A1332, Revision 4,
dated October 31, 2013, also specified
that airplanes having line numbers
YA091 through YA097 were
inadvertently removed from Boeing
Alert Service Bulletin 737–31A1332,
Revision 3, dated March 28, 2012, and
are now included in Group 1 airplanes
as identified in Boeing Alert Service
Bulletin 737–31A1332, Revision 4,
dated October 31, 2013.
In addition, we are also correcting a
typographical error in paragraph (i)(1) of
AD 2012–19–11, Amendment 39–17206
(77 FR 60296, October 3, 2012), which
refers to paragraph (h) of that AD;
paragraph (i)(1) of AD 2012–19–11
should refer to paragraph (g) of that AD.
Operators that accomplished Boeing
Special Attention Service Bulletin 737–
21–1165, Revision 1, dated July 16,
2010, get credit for the actions in
paragraph (g) of this AD; operators
cannot get credit for the concurrent
actions required by paragraph (h) of this
AD because they cannot accomplish the
concurrent actions using Boeing Special
Attention Service Bulletin 737–21–
1165, Revision 1, dated July 16, 2010.
We have revised paragraphs (i)(2)
through (i)(4) of AD 2012–19–11,
Amendment 39–17206 (77 FR 60296,
October 3, 2012), to specify certain
airplane variable numbers to clearly
identify the airplanes that are allowed to
receive credit for previous actions using
certain service information and to match
the information specified in AD 2013–
02–05, Amendment 39–17326 (78 FR
6202, January 30, 2013). The airplanes
identified in paragraphs (j)(2) through
(j)(4) of this proposed AD match the
airplanes specified in paragraphs (i)(1)
through (i)(3) of AD 2013–02–05; these
E:\FR\FM\29JYP1.SGM
29JYP1
43985
Federal Register / Vol. 79, No. 145 / Tuesday, July 29, 2014 / Proposed Rules
paragraphs give credit for doing actions
specified in Boeing Alert Service
Bulletin 737–31A1332, Revision 1,
dated June 24, 2010; and Boeing Alert
Service Bulletin 737–31Al332, Revision
2, dated August 18, 2011.
However, airplanes having variable
numbers YA001 through YA008,
YA251, YA501 through YA508, and
YC321 through YC325, were allowed to
take credit for actions as specified in
paragraph (i)(2) and (i)(3) of AD 2012–
19–11, Amendment 39–17206 (77 FR
60296, October 3, 2012). Airplanes
having variable numbers YA001 through
YA008, YA251, YA501 through YA508,
and YC321 through YC325 are now
excluded from the credit for doing
certain actions given in paragraphs (j)(2)
and (j)(3) of this proposed AD; therefore,
we have provided a new compliance
time for those airplanes in paragraph (i)
of this AD.
Relevant Service Information
We reviewed the following service
information:
• Boeing Special Attention Service
Bulletin 737–21–1164, Revision 2, dated
August 23, 2013.
• Boeing Alert Service Bulletin 737–
31A1325, Revision 1, dated July 5, 2012.
• Boeing Alert Service Bulletin 737–
31A1332, Revision 4, dated October 31,
2013.
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–2014–
0487.
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.
Proposed AD Requirements
This proposed AD would retain all
requirements of AD 2012–19–11,
Amendment 39–17206 (77 FR 60296,
October 3, 2012). This proposed AD
would add, for certain airplanes, a
requirement to incorporate related
design changes. This proposed AD also,
for certain airplanes, no longer gives
credit for accomplishing certain
previous actions.
Differences Between This Proposed AD
and the Service Information
Boeing Special Attention Service
Bulletin 737–21–1164, Revision 2, dated
August 23, 2013; and Boeing Alert
Service Bulletin 737–31A1325, Revision
1, dated July 5, 2012; specify to contact
the manufacturer for instructions on
how to repair certain conditions, but
this proposed AD would require
repairing those conditions in one of the
following ways:
• In accordance with a method that
we approve; or
• Using data that meet the
certification basis of the airplane, and
that have been approved by the Boeing
Commercial Airplanes Organization
Designation Authorization (ODA) whom
we have authorized to make those
findings.
Costs of Compliance
We estimate that this proposed AD
affects 1,618 airplanes of U.S. registry.
We estimate the following costs to
comply with this proposed AD:
ESTIMATED COSTS
Cost per
product

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

Action
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 have 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) Is not a ‘‘significant rule’’ under
the DOT Regulatory Policies and
Procedures (44 FR 11034, February 26,
1979),
(3) Will not affect intrastate aviation
in Alaska, and
(4) 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.

flightcrew not receiving an aural warning
during a lack of cabin pressurization event.
We are issuing this AD to prevent the loss of
cabin altitude warning, which could delay
flightcrew recognition of a lack of cabin
pressurization, and could result in
incapacitation of the flightcrew due to
hypoxia (a lack of oxygen in the body), and
consequent loss of control of the airplane.

Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to supersede Airworthiness Directive (AD) 2012-19-
11, which applies to certain The Boeing Company Model 737 airplanes. AD
2012-19-11 currently requires incorporating design changes to improve
the reliability of the cabin altitude warning system by installing a
redundant cabin altitude pressure switch, replacing the aural warning
module (AWM) with a new or reworked AWM, and changing certain wire
bundles or connecting certain previously capped and stowed wires as
necessary. For certain airplanes, AD 2012-19-11 also requires prior or
concurrent incorporation of related design changes by modifying the
instrument panels, installing light assemblies, modifying the wire
bundles, and installing a new circuit breaker, as necessary. Since we
issued AD 2012-19-11, we have determined that certain airplanes were
not included in the requirement to incorporate related design changes.
This proposed AD would add, for certain airplanes, a requirement to
incorporate related design changes. This proposed AD also, for certain
airplanes, no longer gives credit for accomplishing certain previous
actions. We are proposing this AD to prevent the loss of cabin altitude
warning, which could delay flightcrew recognition of a lack of cabin
pressurization, and could result in incapacitation of the flightcrew
due to hypoxia (a lack of oxygen in the body), and consequent loss of
control of the airplane.
DATES: We must receive comments on this proposed AD by September 12,
2014.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Discussion
On September 19, 2012, we issued AD 2012-19-11, Amendment 39-17206
(77 FR 60296, October 3, 2012), for certain The Boeing Company Model
737 airplanes. AD 2012-19-11 requires incorporating design changes to
improve the reliability of the cabin altitude warning system by
installing a redundant cabin altitude pressure switch, replacing the
AWM with a new or reworked AWM, and changing certain wire bundles or
connecting certain previously capped and stowed wires as necessary. For
certain airplanes, AD 2012-19-11 also requires prior or concurrent
incorporation of related design changes by modifying the instrument
panels, installing light assemblies, modifying the wire bundles, and
installing a new circuit breaker, as necessary. AD 2012-19-11 resulted
from a report of a flightcrew not receiving an aural warning during a
lack of cabin pressurization event. We issued AD 2012-19-11 to prevent
the loss of cabin altitude warning, which could delay flightcrew
recognition of a lack of cabin pressurization, and could result in
incapacitation of the flightcrew due to hypoxia (a lack of oxygen in
the body), and consequent loss of control of the airplane.
Other Related Rulemaking
The concurrent actions for AD 2012-19-11, Amendment 39-17206 (77 FR
60296, October 3, 2012), are the primary corrective actions for AD
2011-03-14, Amendment 39-16598 (76 FR 6529, February 7, 2011), and AD
2013-02-05, Amendment 39-17326 (78 FR 6202, January 30, 2013). AD 2011-
03-14 and AD 2013-02-05 provide the necessary wiring configuration to
perform the corrective actions for AD 2012-19-11. AD 2011-03-14 (for
certain Model 737-100, -200, -200C, -300, -400, and -500 series
airplanes) and AD 2013-02-05 (for certain Model 737-600, -700, -700C, -
800, -900, and -900ER series airplanes) were issued to prevent failure
of the flightcrew to recognize and react to a valid cabin altitude
warning horn, which could result in incapacitation of the flightcrew
due to hypoxia (a lack of oxygen in the body), and consequent loss of
control of the airplane.
Actions Since AD 2012-19-11, Amendment 39-17206 (77 FR 60296, October
3, 2012), Was Issued
Since we issued AD 2012-19-11, Amendment 39-17206 (77 FR 60296,
October 3, 2012), we have reviewed new service information for the
actions required by paragraph (g) of AD 2012-19-11, which refers to
Boeing Special Attention Service Bulletin 737-21-1164, Revision 1,
dated May 17, 2012, as one of the appropriate sources of service
information. Boeing Special Attention Service Bulletin 737-21-1164,
Revision 2, dated August 23, 2013, provides essentially the same
procedure for accomplishing the actions, except for certain airplanes,
Boeing Special Attention Service Bulletin 737-21-1164, Revision 2,
dated August 23, 2013, specifies to contact the manufacturer for the
installation and replacement of certain wire bundles.
We also have reviewed new service information for the concurrent
actions required by paragraph (h) of AD 2012-19-11, Amendment 39-17206
(77 FR 60296, October 3, 2012), which refers to Boeing Alert Service
Bulletin 737-31A1325, dated January 11, 2010; and Boeing Alert Service
Bulletin 737-31A1332, Revision 3, dated March 28, 2012; as the
appropriate sources of service information. Boeing Alert Service
Bulletin 737-31A1325, Revision 1, dated July 5, 2012; and Boeing Alert
Service Bulletin 737-31A1332, Revision 4, dated October 31, 2013;
provide essentially the same procedures for accomplishing the
concurrent actions, except, for certain airplanes, Boeing Alert Service
Bulletin 737-31A1325, Revision 1, dated July 5, 2012, specifies to
contact the manufacturer for modification, installation, and repair
instructions. Boeing Alert Service Bulletin 737-31A1332, Revision 4,
dated October 31, 2013, also specified that airplanes having line
numbers YA091 through YA097 were inadvertently removed from Boeing
Alert Service Bulletin 737-31A1332, Revision 3, dated March 28, 2012,
and are now included in Group 1 airplanes as identified in Boeing Alert
Service Bulletin 737-31A1332, Revision 4, dated October 31, 2013.
In addition, we are also correcting a typographical error in
paragraph (i)(1) of AD 2012-19-11, Amendment 39-17206 (77 FR 60296,
October 3, 2012), which refers to paragraph (h) of that AD; paragraph
(i)(1) of AD 2012-19-11 should refer to paragraph (g) of that AD.
Operators that accomplished Boeing Special Attention Service Bulletin
737-21-1165, Revision 1, dated July 16, 2010, get credit for the
actions in paragraph (g) of this AD; operators cannot get credit for
the concurrent actions required by paragraph (h) of this AD because
they cannot accomplish the concurrent actions using Boeing Special
Attention Service Bulletin 737-21-1165, Revision 1, dated July 16,
2010.
We have revised paragraphs (i)(2) through (i)(4) of AD 2012-19-11,
Amendment 39-17206 (77 FR 60296, October 3, 2012), to specify certain
airplane variable numbers to clearly identify the airplanes that are
allowed to receive credit for previous actions using certain service
information and to match the information specified in AD 2013-02-05,
Amendment 39-17326 (78 FR 6202, January 30, 2013). The airplanes
identified in paragraphs (j)(2) through (j)(4) of this proposed AD
match the airplanes specified in paragraphs (i)(1) through (i)(3) of AD
2013-02-05; these
[[Page 43985]]
paragraphs give credit for doing actions specified in Boeing Alert
Service Bulletin 737-31A1332, Revision 1, dated June 24, 2010; and
Boeing Alert Service Bulletin 737-31Al332, Revision 2, dated August 18,
2011.
However, airplanes having variable numbers YA001 through YA008,
YA251, YA501 through YA508, and YC321 through YC325, were allowed to
take credit for actions as specified in paragraph (i)(2) and (i)(3) of
AD 2012-19-11, Amendment 39-17206 (77 FR 60296, October 3, 2012).
Airplanes having variable numbers YA001 through YA008, YA251, YA501
through YA508, and YC321 through YC325 are now excluded from the credit
for doing certain actions given in paragraphs (j)(2) and (j)(3) of this
proposed AD; therefore, we have provided a new compliance time for
those airplanes in paragraph (i) of this AD.
Relevant Service Information
We reviewed the following service information:
Boeing Special Attention Service Bulletin 737-21-1164,
Revision 2, dated August 23, 2013.
Boeing Alert Service Bulletin 737-31A1325, Revision 1,
dated July 5, 2012.
Boeing Alert Service Bulletin 737-31A1332, Revision 4,
dated October 31, 2013.
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-2014-0487.
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.
Proposed AD Requirements
This proposed AD would retain all requirements of AD 2012-19-11,
Amendment 39-17206 (77 FR 60296, October 3, 2012). This proposed AD
would add, for certain airplanes, a requirement to incorporate related
design changes. This proposed AD also, for certain airplanes, no longer
gives credit for accomplishing certain previous actions.
Differences Between This Proposed AD and the Service Information
Boeing Special Attention Service Bulletin 737-21-1164, Revision 2,
dated August 23, 2013; and Boeing Alert Service Bulletin 737-31A1325,
Revision 1, dated July 5, 2012; specify to contact the manufacturer for
instructions on how to repair certain conditions, but this proposed AD
would require repairing those conditions in one of the following ways:
In accordance with a method that we approve; or
Using data that meet the certification basis of the
airplane, and that have been approved by the Boeing Commercial
Airplanes Organization Designation Authorization (ODA) whom we have
authorized to make those findings.
Costs of Compliance
We estimate that this proposed AD affects 1,618 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Parts Cost per
Action Labor cost cost product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Install a redundant cabin Up to 62 work-hours x $33,576 Up to $38,846.. Up to $62,852,828.

wire bundles or connect certain
capped and stowed wires
[retained actions from AD 2012-
19-11, Amendment 39-17206 (77
FR 60296, October 3, 2012), for
1,618 airplanes].
Modify the instrument panels, Up to 92 work-hours x 5,292 Up to $13,112.. Up to $20,926,752.

----------------------------------------------------------------------------------------------------------------
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 have 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) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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
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)
2012-19-11, Amendment 39-17206 (77 FR 60296, October 3, 2012), and
adding the following new AD:
The Boeing Company: Docket No. FAA-2014-0487; Directorate Identifier
2014-NM-026-AD.
(a) Comments Due Date
The FAA must receive comments on this AD action by September 12,
2014.
(b) Affected ADs
This AD replaces AD 2012-19-11, Amendment 39-17206 (77 FR 60296,
October 3, 2012).
(c) Applicability
This AD applies to The Boeing Company airplanes, certificated in
any category, as identified in paragraphs (c)(1) and (c)(2) of this
AD.
(1) Model 737-100, -200, -200C, -300, -400, and -500 series
airplanes, as identified in Boeing Special Attention Service
Bulletin 737-21-1164, Revision 2, dated August 23, 2013.
(2) Model 737-600, -700, -700C, -800, -900, and -900ER series

Conditioning.
(e) Unsafe Condition
This AD was prompted by the report of a flightcrew not receiving
an aural warning during a lack of cabin pressurization event. We are
issuing this AD to prevent the loss of cabin altitude warning, which
could delay flightcrew recognition of a lack of cabin
pressurization, and could result in incapacitation of the flightcrew
due to hypoxia (a lack of oxygen in the body), and consequent loss
of control of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Retained Installation
This paragraph restates the actions required by paragraph (g) of
