Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2014-0057; Directorate Identifier 2013-NM-210-AD; 
Amendment 39-18044; AD 2014-25-03]
RIN 2120-AA64

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 
series airplanes. This AD was prompted by reports from multiple 
operators that have found fatigue cracking in the corners of the 
forward galley service doorway. This AD requires repetitive inspections 
for any cracking of the skin and bear strap doublers in the corners of 
the forward galley service doorway, and corrective action if necessary. 
This AD also provides optional terminating actions for certain 
repetitive inspections. We are issuing this AD to detect and correct 
fatigue cracking, which could result in rapid loss of cabin pressure.

DATES: This AD is effective January 16, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of January 16, 
2015.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain The Boeing Company 
Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. The 
NPRM published in the Federal Register on February 25, 2014 (79 FR 
10429). The NPRM was prompted by reports from multiple operators that 
have found fatigue cracking of the skin and bear strap in the corners 
of the forward galley service doorway. Some of the reported cracks were 
found outside of areas of directed or recommended inspections, or in 
areas modified as specified in previous revisions of Boeing Alert 
Service Bulletin 737-53A1116. Some airplanes were found to have 
multiple cracks in the corner areas. The NPRM proposed to require 
repetitive inspections for any cracking of the skin and bear strap 
doublers in the corners of the forward galley service doorway, and 
corrective action if necessary. The NPRM also proposed to provide 
optional terminating actions for certain repetitive inspections. We are 
issuing this AD to detect and correct fatigue cracking, which could 
result in rapid loss of cabin pressure.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM (79 
FR 10429, February 25, 2014) and the FAA's response to each comment.

Request To Clarify Terminating Action for Initial Inspection

    Southwest Airlines (Southwest) requested that the NPRM (79 FR 
10429, February 25, 2014) be revised to include provisions in paragraph 
(i)(1) of the proposed AD for terminating the requirement proposed by 
paragraph (g) of the proposed AD for initial inspections in the areas 
of the upper aft corner that are covered by the repair. Southwest noted 
that paragraph (i)(1) of the proposed AD provides for terminating the 
repetitive inspections required by paragraph (g) of the AD. Southwest 
also stated that it would like clarification on whether accomplishment 
of a repair also terminates the initial inspection requirements of 
paragraph (g) of the proposed AD for the upper aft corner.
    We agree to revise paragraph (i)(1) of this AD. Notes in the tables 
of paragraph 1.E., ``Compliance,'' of Boeing Alert Service Bulletin 
737-53A1116, Revision 4, dated September 30, 2013, state that 
accomplishing certain repairs terminates repetitive inspections in the 
areas covered by the repair. We have determined that accomplishing the 
repair as required by paragraph (i)(1) of this AD would also terminate 
the initial inspection requirement for that repaired corner. We have 
coordinated this issue with Boeing and revised paragraph (i)(1) of this 
AD to terminate the initial inspection requirement as well. We have 
also revised paragraphs (i)(2) and (i)(3) of this AD accordingly.

Request To Add a Repair as a Method of Compliance

    Southwest requested that paragraph (i) of the proposed AD (79 FR 
10429, February 25, 2014), be revised to specifically provide for 
repairs accomplished using information from certain repair procedures 
specified in Boeing Alert Service Bulletin 737-53A1116, Revision 4, 
dated September 30, 2013, and to allow accomplishment of those repairs 
as terminating action for the inspection requirements of paragraph (g) 
of the proposed AD. Southwest also requested an additional provision to 
allow Repair 2 of section 53-10-01 of the Boeing 737-300/-500 
Structural Repair Manual as terminating action for the initial and 
repetitive inspections proposed in paragraph (g) of the proposed AD.
    We partially agree with the request. Certain repair procedures are 
addressed in Boeing Alert Service Bulletin 737-53A1116, Revision 4, 
dated September 30, 2013, as possible methods of corrective action or 
preventative modification. Provisions for these repair procedures are 
provided in paragraphs (i)(2) and (i)(3) of this AD. However, Repair 2 
of section 53-10-01 of the Boeing 737-300/-500 Structural Repair Manual 
was not addressed in Boeing Alert Service Bulletin 737-53A1116, 
Revision 4, dated September 30, 2013, or considered during development 
of this AD. We do not consider that delaying this action until the 
manufacturer revises the service

[[Page 73815]]

information to include the information in Repair 2 is warranted. To 
delay this action would be inappropriate since we have determined that 
an unsafe condition exists and that actions required by this AD must be 
conducted to ensure continued safety. Operators may apply for an 
alternative method of compliance (AMOC) under the requirements of 
paragraph (m) of this AD.

Request To Revise Credit Paragraph

    Southwest noted that paragraph (k) of the proposed AD (79 FR 10429, 
February 25, 2014), gives credit for inspections of the upper corners 
of the forward galley doors, provided that the preventative 
modification is also inspected in accordance with the requirements of 
paragraph (g) of the proposed AD. Southwest also noted that paragraph 
(k) of the proposed AD does not specifically mention whether credit is 
given for previous repairs that were accomplished using the specified 
service information or explain how these repairs affect compliance with 
the initial inspection requirements of paragraph (g) of the AD.
    We agree to clarify the intent of paragraph (k) of this AD. If any 
inspection of the upper corners of the forward galley service door was 
accomplished before the effective date of this AD using any of the 
service information identified in paragraphs (k)(1), (k)(2), (k)(3), 
and (k)(4) of this AD instead of Boeing Alert Service Bulletin 737-
53A1116, Revision 4, dated September 30, 2013, those inspections are 
considered acceptable for compliance with certain requirements of 
paragraph (g) of this AD. Certain modifications specified in those 
previous service bulletins that were previously determined to be 
terminating action for inspections, have now been determined to need 
further inspection in accordance with paragraph (g) of this AD and 
Boeing Alert Service Bulletin 737-53A1116, Revision 4, dated September 
30, 2013. Paragraphs (i)(1) and (i)(2) of this AD address repairs of 
the upper corners and clarify that accomplishing the repairs terminates 
the requirements of paragraph (g) of this AD for the inspections of the 
repaired area. Repetitive inspections specified in paragraph (g) of 
this AD are required and are only terminated if optional terminating 
action specified in paragraph (i) of this AD is done. We have not 
changed the AD in this regard.

Request To Accommodate Certain AMOCs

    Southwest noted that Note 14 in the Accomplishment Instructions of 
Boeing Alert Service Bulletin 737-53A1116, Revision 4, dated September 
30, 2013, specifies that inspections as given in that service bulletin 
for the upper forward corner are not necessary in the repaired area if, 
among other conditions, ``the repair has been approved as an 
Alternative Method of Compliance (AMOC) to AD 2008-11-04.'' Southwest 
pointed out that AD 2008-11-04, Amendment 39-15526 (73 FR 29421, May 
21, 2008), has been superseded by AD 2014-05-21, Amendment 39-17794 (79 
FR 14992, March 18, 2014), and requests that Note 14 of the 
Accomplishment Instructions of Boeing Alert Service Bulletin 737-
53A1116, Revision 4, dated September 30, 2013, also apply to repairs 
approved as an AMOC to AD 2014-05-21.
    We partially agree with Southwest's request. We cannot revise 
Boeing's service information. However, we have added paragraph (j)(3) 
to this AD to provide an exception to Boeing Alert Service Bulletin 
737-53A1116, Revision 4, dated September 30, 2013, and allow a Boeing-
provided repair that has been approved as an AMOC to AD 2014-05-21, 
Amendment 39-17794 (79 FR 14992, March 18, 2014), for the repaired area 
only, provided the approval was made before the effective date of this 
AD and the repair doubler covers the doorway upper forward corner and 
the upper hinge cutout.

Effect of Winglets on This AD

    Aviation Partners Boeing stated that accomplishing the supplemental 
type certificate (STC) ST01219SE (http://rgl.faa.gov/
Regulatory_and_Guidance_Library/rgstc.nsf/0/
ebd1cec7b301293e86257cb30045557a/$FILE/ST01219SE.pdf) does not affect 
the actions specified in the NPRM (79 FR 10429, February 25, 2014).
    We concur with the commenter. We have redesignated paragraph (c) of 
the NPRM (79 FR 10429, February 25, 2014) as (c)(1) and added new 
paragraph (c)(2) to this final rule to state that installation of STC 
ST01219SE (http://rgl.faa.gov/Regulatory_and_Guidance_Library/
rgstc.nsf/0/ebd1cec7b301293e86257cb30045557a/$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.

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:
     Are consistent with the intent that was proposed in the 
NPRM (79 FR 10429, February 25, 2014) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 10429, February 25, 2014).
    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
--------------------------------------------------------------------------------------------------------------------------------------------------------
             Action                      Labor cost              Parts cost          Cost per product                 Cost on U.S. operators
--------------------------------------------------------------------------------------------------------------------------------------------------------
Inspection......................  19 work-hours x $85 per   None...............  $1,615 per inspection    $676,685 per inspection cycle.
                                   hour = $1,615 per                              cycle.
                                   inspection cycle.
--------------------------------------------------------------------------------------------------------------------------------------------------------

    We have received no definitive data that would enable us to provide 
cost estimates for any on-condition actions specified in this AD. We 
have no way of determining the number of aircraft that might need this 
repair.

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

[[Page 73816]]

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

    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 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.

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 adding the following new airworthiness 
directive (AD):

2014-25-03 The Boeing Company: Amendment 39-18044 ; Docket No. FAA-
2014-0057; Directorate Identifier 2013-NM-210-AD.

(a) Effective Date

    This AD is effective January 16, 2015.

(b) Affected ADs

    None.

(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-
53A1116, Revision 4, dated September 30, 2013.

rgstc.nsf/0/ebd1cec7b301293e86257cb30045557a/$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 from multiple operators that

or modified doorway corner only.

(j) Exceptions to the Service Information

    (1) Where Boeing Alert Service Bulletin 737-53A1116, Revision 4, 
dated September 30, 2013, specifies a compliance time ``after

[[Page 73817]]

the Revision 4 date of this service bulletin,'' this AD requires 
compliance within the specified compliance time ``after the 
effective date of this AD.''
    (2) Where Boeing Alert Service Bulletin 737-53A1116, Revision 4, 
dated September 30, 2013, specifies to contact Boeing for repair 
instructions: Before further flight, repair the cracking using a 
method approved in accordance with the procedures specified in

has been approved as an alternative method of compliance (AMOC) to 
AD 2008-11-04, Amendment 39-15526 (73 FR 29421, May 21, 2008). This 
AD also does not require inspections for the upper forward corner 
given in Boeing Alert Service Bulletin 737-53A1116, Revision 4, 
dated September 30, 2013, if there is a Boeing-provided repair 
approved as an AMOC to the corresponding requirements of AD 2014-05-
21, Amendment 39-17794 (79 FR 14992, March 18, 2014), for the 
repaired area only, provided the approval was made before the 
effective date of this AD and the repair doubler covers the doorway 
upper forward corner and the upper hinge cutout.

(k) Credit for Previous Actions

    This paragraph provides credit for the inspections of the upper 
corners of the forward galley service doors specified in paragraph 
(g) of this AD, if those actions were performed before the effective 
date of this AD using any of the service information identified in 
paragraphs (k)(1) through (k)(4) of this AD (which are not 
incorporated by reference in this AD), provided that any 
preventative modification installed using this service information 
is inspected in accordance with paragraph (g) of this AD.
    (1) Boeing Service Bulletin 737-53-1116, dated July 21, 1988.
