Federal Register Abstract
We are superseding Airworthiness Directive (AD) 2005-07-12, which applies to certain the Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. AD 2005-07-12 required detailed and eddy current inspections to detect cracking of the frame web around the cutout for the doorstop intercostal strap at the aft side of the station (STA) 291.5 frame at stringer 16R, and corrective action if necessary. Since we issued AD 2005-07-12, we received reports of new findings of cracking at various locations of the STA 277 to STA 291.5 frames and intercostals, including webs, chords, clips, and shear ties, between stringers 7R and 17R. This new AD requires inspections for cracking at the forward galley door cutout, and corrective actions if necessary. This new AD also reduces a certain inspection threshold required by AD 2005-07-12. We are issuing this AD to detect and correct fatigue cracking of the aft frame and frame support structure of the forward galley door, which could result in a severed fuselage frame web, rapid decompression of the airplane, and possible loss of the forward galley door.

ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are superseding Airworthiness Directive (AD) 2005-07-12,
which applies to certain the Boeing Company Model 737-100, -200, -200C,
-300, -400, and -500 series airplanes. AD 2005-07-12 required detailed
and eddy current inspections to detect cracking of the frame web around
the cutout for the doorstop intercostal strap at the aft side of the
station (STA) 291.5 frame at stringer 16R, and corrective action if
necessary. Since we issued AD 2005-07-12, we received reports of new
findings of cracking at various locations of the STA 277 to STA 291.5
frames and intercostals, including webs, chords, clips, and shear ties,
between stringers 7R and 17R. This new AD requires inspections for
cracking at the forward galley door cutout, and corrective actions if
necessary. This new AD also reduces a certain inspection threshold
required by AD 2005-07-12. We are issuing this AD to detect and correct
fatigue cracking of the aft frame and frame support structure of the
forward galley door, which could result in a severed fuselage frame
web, rapid decompression of the airplane, and possible loss of the
forward galley door.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2005-07-12, Amendment 39-14036 (70 FR 17596,
April 7, 2005). AD 2005-07-12 applied to certain The Boeing Company
Model 737-100, -200, -300, -400, and -500 series airplanes. The NPRM
published in the Federal Register on October 2, 2013 (78 FR 60804). The
NPRM was prompted by reports of new findings of cracking at various
locations of the STA 277 to STA 291.5 frames and intercostals,
including webs, chords, clips, and shear ties, between stringers 7R and
17R. The NPRM proposed to continue to require detailed and eddy current
inspections to detect cracking of the frame web around the cutout for
the doorstop intercostal strap at the aft side of the STA 291.5 frame
at stringer 16R, and corrective action if necessary. The NPRM also
proposed to require new inspections for cracking at the forward galley
door cutout, and corrective actions if necessary. In addition, the NPRM
also proposed to reduce a certain inspection threshold required by AD
2005-07-12. We are issuing this AD to
[[Page 67045]]
detect and correct fatigue cracking of the aft frame and frame support
structure of the forward galley door, which could result in a severed
fuselage frame web, rapid decompression of the airplane, and possible
loss of the forward galley door.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the NPRM (78
FR 60804, October 2, 2013), and the FAA's response to each comment.
Boeing stated that it concurs with the contents of the NPRM (78 FR
60804, October 2, 2013).
Effect of Winglets on AD
Aviation Partners Boeing stated that accomplishing the installation
of winglets per supplemental type certificate (STC) ST01219SE (http://
rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/
082838ee177dbf62862576a4005cdfc0/$FILE/ST01219SE.pdf) does not affect
the actions specified in the NPRM (78 FR 60804, October 2, 2013).
We concur with the commenter. We have redesignated paragraph (c) of
the NPRM (78 FR 60804, October 2, 2013) as (c)(1) in this AD and added
new paragraph (c)(2) to this AD to state that installation of STC
ST01219SE (http://rgl.faa.gov/Regulatory_and_Guidance_Library/
rgstc.nsf/0/082838ee177dbf62862576a4005cdfc0/$FILE/ST01219SE.pdf) does
not affect the ability to accomplish the actions required by this final
rule. Therefore, for airplanes on which STC ST01219SE is installed, a
``change in product'' alternative method of compliance (AMOC) approval
request is not necessary to comply with the requirements of 14 CFR
39.17.
Request To Clarify That Certain Inspections Are Not Required for Areas
With Existing Repairs
Southwest Airlines (SWA) requested that paragraph (h)(1) of the
NPRM (78 FR 60804, October 2, 2013), be revised to include language
stating that when operators are accomplishing Steps 2 and 6 in Part 2
of Paragraph 3.B., ``Work Instructions,'' of the Accomplishment
Instructions of Boeing Alert Service Bulletin 737-53A1241, Revision 1,
dated June 11, 2013, they do not need to do inspections in areas that
are common to repairs that were previously approved by Boeing via FAA
Form 8100-9, ``Statement of Compliance with Airworthiness Standards.''
We infer that the basis for SWA's request is that the existing repairs
have inspections included in the engineering for those repairs, so the
inspections included in the service information are not needed.
SWA also requested that the NPRM (78 FR 60804, October 2, 2013), be
revised to clarify that inspections are not required in areas that are
common to existing repairs that were installed using a certain repair
in the applicable Boeing Model 737 structural repair manual (SRM). SWA
noted that Step 6 in Part 2 of Paragraph 3.B., ``Work Instructions,''
of the Accomplishment Instructions of Boeing Alert Service Bulletin
737-53A1241, Revision 1, dated June 11, 2013, only addresses repetitive
inspections when a new SRM repair is installed. We infer that SWA is
suggesting that the service information should have also addressed
repetitive inspections for areas with a certain existing SRM repair
installed.
We agree with the commenter. The inspections required by paragraph
(h)(1) of this AD include detailed and surface eddy current inspections
that cannot be accomplished with certain repairs installed. Repairs 1,
15, and 16, of Chapter 53 of the applicable Boeing 737 SRM, are
referenced in the Accomplishment Instructions of Boeing Alert Service
Bulletin 737-53A1241, Revision 1, dated June 11, 2013, and are
considered corrective actions for cracking found during the inspections
required by paragraph (h)(1) of this AD. These SRM repairs can also be
used as a preventive modification.
We revised paragraph (h)(1) in this AD to state that
``Accomplishment of a repair specified in Steps 1.a., 2.a., 6.a., or
6.b. of Part 2 of the Accomplishment Instructions of Boeing Alert
Service Bulletin 737-53A1241, Revision 1, dated June 11, 2013, as
applicable, and except as required by paragraph (k)(1) of this AD,
terminates the inspections required by this paragraph for the repaired
area(s) only.''
Request To Address Notes 11 and 13 in the Service Information Regarding
Existing Repairs and Existing Repairs at Certain Body Stations
SWA requested clarification regarding existing repairs common to
the inspection areas addressed in Part 2 of Paragraph 3.B., ``Work
Instructions,'' of the Accomplishment Instructions of Boeing Alert
Service Bulletin 737-53A1241, Revision 1, dated June 11, 2013. SWA
observed that Notes 11 and 13 in Paragraph 3.A., ``General
Information,'' of that service bulletin include provisions for omitting
inspections in areas covered by repairs that were previously approved
by Boeing via FAA Form 8100-9, ``Statement of Compliance with
Airworthiness Standards,'' but those notes are not included or
referenced in Part 2 of Paragraph 3.B., ``Work Instructions.''
SWA also requested approval for existing repairs common to the body
station (BS) 291.5 frame at locations from stringer (STR) 8R to STR 15R
that were previously approved by Boeing via FAA Form 8100-9,
``Statement of Compliance with Airworthiness Standards,'' as
terminating action for the inspection requirements in paragraph (h)(1)
of the NPRM (78 FR 60804, October 2, 2013), for the repaired area only.
Furthermore, SWA requested approval for existing repairs common to
the BS 277 frame and shear ties between STR 7R and STR 17R that were
previously approved by Boeing via FAA Form 8100-9, ``Statement of
Compliance with Airworthiness Standards,'' or that were installed using
certain repairs in the applicable Boeing 737 SRM as terminating action
for the inspection requirements of paragraph (h)(1) of the NPRM (78 FR
60804, October 2, 2013), for the repaired areas only.
We agree that the existing repairs mentioned by the commenter can
be used as terminating action for the inspection requirements of
paragraph (h)(1) of this AD. Several SRM repairs are referenced in
Steps 6.a. and 6.b. of Part 2 of the Accomplishment Instructions of
Boeing Alert Service Bulletin 737-53A1241, Revision 1, dated June 11,
2013, and are considered corrective actions for cracking found during
the inspections required by paragraph (h)(1) of this AD. The notes to
Steps 6.a. and 6.b. state that the SRM repairs terminate the repetitive
inspections. As stated previously, paragraph (h)(1) of this AD was
revised accordingly.
We have also added a new paragraph (i), Terminating Action, to this
AD and redesignated subsequent paragraphs accordingly. Paragraph (i) of
this AD states ``The inspections required by paragraph (h)(1) of this
AD may be terminated at areas with repairs installed prior to the
effective date of this AD, provided the repairs meet the conditions
specified in note 11 or note 13 of paragraph 3.A., ``General
Information,'' of the Accomplishment Instructions of Boeing Alert
Service Bulletin 737-53A1241, Revision 1, dated June 11, 2013.''
Request To Include Exception to the Service Information Specifications
SWA requested that the NPRM (78 FR 60804, October 2, 2013) address
a typographical error that appears in the
[[Page 67046]]
title to figure 5 of Boeing Alert Service Bulletin 737-53A1241,
Revision 1, dated June 11, 2013. SWA noted that the title refers to STR
16R, however, the inspection location is STR 14R.
We agree to address this typographical error in Boeing Alert
Service Bulletin 737-53A1241, Revision 1, dated June 11, 2013, and have
added a new paragraph (k)(3) to this AD to notify operators that the
title to figure 5 should reference STR 14R.
Clarification of Affected Airplanes
We have added ``certificated in any category'' to the applicability
specified in paragraph (c)(1) of this AD to clarify the affected
airplanes.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this AD with the changes described previously and minor editorial
changes. We have determined that these minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM (78 FR 60804, October 2, 2013) for correcting the unsafe
condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM (78 FR 60804, October 2, 2013).
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this AD.
Costs of Compliance
We estimate that this AD affects 419 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Inspections [retained from AD 2 work-hours x $85 None............... $170 per $71,230 per
2005-07-12, Amendment 39 14036 per hour = $170 inspection cycle. inspection cycle.

----------------------------------------------------------------------------------------------------------------
We have received no definitive data that would enable us to provide
a cost estimate for the on-condition actions specified in the service
information.
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 AD will not have federalism
implications under Executive Order 13132. This AD will 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 this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in, 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

reference, Safety.
Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 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)
2005-07-12, Amendment 39-14036 (70 FR 17596, April 7, 2005), and adding
the following new AD:
2014-22-06 The Boeing Company: Amendment 39-18011 ; Docket No. FAA-
2013-0836; Directorate Identifier 2013-NM-126-AD.
(a) Effective Date
This AD is effective December 17, 2014.
(b) Affected ADs
This AD replaces AD 2005-07-12, Amendment 39-14036 (70 FR 17596,
April 7, 2005).
(c) Applicability
(1) This AD applies to The Boeing Company Model 737-100, -200, -
200C, -300, -400, and -500 series airplanes, certificated in any
category, as identified in Boeing Alert Service Bulletin 737-
53A1241, Revision 1, dated June 11, 2013.

ST01219SE (http://rgl.faa.gov/Regulatory_and_Guidance_Library/
rgstc.nsf/0/082838ee177dbf62862576a4005cdfc0/$FILE/ST01219SE.pdf)
does not affect the ability to accomplish the actions required by
this AD. Therefore, for airplanes on which STC ST01219SE is
installed, a ``change in product'' alternative method of compliance
(AMOC) approval request is not necessary to comply with the
requirements of 14 CFR 39.17.
(d) Subject
Air Transport Association (ATA) of America Code 53, Fuselage.
(e) Unsafe Condition
This AD was prompted by reports of new findings of cracking at
various locations of the stations (STA) 277 to STA 291.5 frames and
intercostals, including webs, chords, clips, and shear ties, between
stringers 7R and 17R. We are issuing this AD to detect
[[Page 67047]]
and correct fatigue cracking of the aft frame and frame support
structure of the forward galley door, which could result in a
severed fuselage frame web, rapid decompression of the airplane, and
possible loss of the forward galley door.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Group 1 Airplanes: Inspections and Corrective Actions
For airplanes identified as Group 1 in Boeing Alert Service

(h) Group 2 and Group 3 Airplanes: Inspections and Corrective Actions
(1) For airplanes identified as Group 2 and Group 3 in Boeing
Alert Service Bulletin 737-53A1241, Revision 1, dated June 11, 2013:
Except as provided by paragraph (k)(2) of this AD, at the applicable
times specified in tables 1 and 2 in paragraph 1.E, ``Compliance,''
of Boeing Alert Service Bulletin 737-53A1241, Revision 1, dated June
11, 2013, do detailed and surface high frequency eddy current (HFEC)
inspections, as applicable, for cracking in the forward galley door
cutout, in accordance with Part 2 of the Accomplishment Instructions
of Boeing Alert Service Bulletin 737-53A1241, Revision 1, dated June
11, 2013. Repeat the detailed and surface HFEC inspections
thereafter at the applicable intervals specified in tables 1 and 2
in paragraph 1.E, ``Compliance,'' of Boeing Alert Service Bulletin
737-53A1241, Revision 1, dated June 11, 2013. If any crack is found,
before further flight, do all applicable corrective actions in
accordance with Part 2 of the Accomplishment Instructions of Boeing
Alert Service Bulletin 737-53A1241, Revision 1, dated June 11, 2013,
except as required by paragraph (k)(1) of this AD. Accomplishment of
a repair specified in Steps 1.a., 2.a., 6.a., or 6.b. of Part 2, of
the Accomplishment Instructions of Boeing Alert Service Bulletin
737-53A1241, Revision 1, dated June 11, 2013, as applicable, and
except as required by paragraph (k)(1) of this AD, terminates the
inspections required by this paragraph for the repaired area(s)
only.
(2) Removal and replacement of a cracked part, in accordance
with Part 2 of the Accomplishment Instructions of Boeing Alert
Service Bulletin 737-53A1241, Revision 1, dated June 11, 2013, does
not terminate the repetitive inspections required by paragraph
(h)(1) of this AD.
(i) Terminating Action
The inspections required by paragraph (h)(1) of this AD may be
terminated at areas with repairs installed prior to the effective
date of this AD, provided the repairs meet the conditions specified
in note 11 or note 13 of paragraph 3.A., ``General Information,'' of
the Accomplishment Instructions of Boeing Alert Service Bulletin
737-53A1241, Revision 1, dated June 11, 2013.
(j) Optional Terminating Action
Accomplishment of the preventive modification on the STA 291.5
frame web, in accordance with Part 2 of the Accomplishment
Instructions of Boeing Alert Service Bulletin 737-53A1241, Revision
1, dated June 11, 2013, terminates the inspections required by
paragraph (h)(1) of this AD for the area that is common to the
preventive modification.
(k) Exceptions to the Service Information
(1) Where Boeing Alert Service Bulletin 737-53A1241, Revision 1,
dated June 11, 2013, specifies to contact Boeing for a corrective
action: Before further flight, do the applicable action using a
method approved in accordance with the procedures specified in
paragraph (m) of this AD.
(2) Where paragraph 1.E., ``Compliance,'' of Boeing Alert
Service Bulletin 737-53A1241, Revision 1, dated June 11, 2013,
specifies a compliance time ``after the date on Revision 1 of this
service bulletin,'' this AD requires compliance within the specified
compliance time after the effective date of this AD.
(3) The title to each page of figure 5 of Boeing Alert Service
Bulletin 737-53A1241, Revision 1, dated June 11, 2013, is incorrect
and refers to ``Stringer 16R'' when it should refer to ``Stringer
14R.''
(l) Credit for Previous Actions
This paragraph provides credit for the actions specified in
paragraph (h)(1) of this AD, if those actions were performed before
the effective date of this AD using Boeing Alert Service Bulletin
737-53A1241, dated June 13, 2002, which is not incorporated by
reference in this AD.
(m) 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
