Airworthiness Directives; the Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: We are superseding Airworthiness Directive (AD) 2014-03-06 for
all the Boeing Company Model 737-100, -200, -200C, -300, -400, and -500
series airplanes. AD 2014-03-06 required repetitive inspections for
cracking of the aft support fitting for the main landing gear (MLG)
beam, and the rear spar upper chord and rear spar web in the area of
rear spar station (RSS) 224.14; and repair if necessary. This AD
clarifies two paragraph references. This AD was prompted by a
determination that two paragraph references were in error. We are
issuing this AD to detect and correct cracking of the aft support
fitting for the main landing gear (MLG) beam, and the rear spar upper
chord and rear spar web in the area of rear spar station (RSS) 224.14,
which could grow and result in a fuel leak and possible fire.

SUPPLEMENTARY INFORMATION:
Discussion
On January 18, 2014, we issued AD 2014-03-06, Amendment 39-17743
(79 FR 12368, March 5, 2014), for all the Boeing Company Model 737-100,
-200, -200C, -300, -400, and -500 series airplanes. AD 2014-03-06
required repetitive inspections for cracking of the aft support fitting
for the main landing gear (MLG) beam, and the rear spar upper chord and
rear spar web in the area of rear spar station (RSS) 224.14; and repair
if necessary. AD 2014-03-06 resulted from reports of cracks found in
the aft support fitting, the rear spar upper chord, and the rear spar
web. We issued AD 2014-03-06 to detect and correct cracking of the aft
support fitting for the main landing gear (MLG) beam, and the rear spar
upper chord and rear spar web in the area of rear spar station (RSS)
224.14, which could grow and result in a fuel leak and possible fire.
Actions Since AD 2014-03-06 Was Issued
Since we issued AD 2014-03-06, Amendment 39-17743 (79 FR 12368,
March 5, 2014), two incorrect paragraph references were found. The
references to paragraphs (g) and (g)(1) in paragraph (h)(2) of AD 2014-
03-06 are incorrect. The correct reference should be to the
introductory text of paragraph (h) and paragraph (h)(1) of AD 2014-03-
06. Paragraph (h)(2) of AD 2014-03-06 is the corrective action for the
inspections required by the introductory text of paragraph (h) and
paragraph (h)(1) of this AD. In order to mandate the corrective actions
for the inspections required by the introductory text of paragraph (h)
and paragraph (h)(1) of this AD, we have revised the references in
paragraph (h)(2) of this AD.
FAA's Determination
We are issuing 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 these same type
designs.
AD Requirements
This AD requires repetitive inspections for cracking of the aft
support fitting for the MLG beam, and the rear spar upper chord and
rear spar web in the area of RSS 224.14; and repair if necessary. This
AD corrects these paragraph references.
[[Page 39301]]
FAA's Justification and Determination of the Effective Date
AD 2014-03-06, Amendment 39-17743 (79 FR 12368, March 5, 2014),
clearly indicated that inspections, and repairs if necessary, are
required. Since this new AD merely corrects incorrect paragraph
references, notice and opportunity for public comment before issuing
this AD are unnecessary.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not provide you with notice and an opportunity to
provide your comments before it becomes effective. However, we invite
you to send any written data, views, or arguments about this AD. Send
your comments to an address listed under the ADDRESSES section. Include
the docket number FAA-2014-0341 and directorate identifier 2014-NM-102-
AD at the beginning of your comments. We specifically invite comments
on the overall regulatory, economic, environmental, and energy aspects
of this AD. We will consider all comments received by the closing date
and may amend this AD because of those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this AD.
Costs of Compliance
We estimate that this AD affects 353 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Parts Cost on U.S.

----------------------------------------------------------------------------------------------------------------
We have received no definitive data that would enable us to provide
cost estimates for the on-condition actions specified in this 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
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 part 39 of the Federal Aviation
Regulations (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)
2014-03-06, Amendment 39-17743 (79 FR 12368, March 5, 2014), and adding
the following new AD:
2014-12-13 The Boeing Company: Amendment 39-17874; Docket No. FAA-
2014-0341; Directorate Identifier 2014-NM-102-AD.
(a) Effective Date
This AD is effective July 25, 2014.
(b) Affected ADs
This AD replaces AD 2014-03-06, Amendment 39-17743 (79 FR 12368,
March 5, 2014).
(c) Applicability
(1) This AD applies to all The Boeing Company Model 737-100, -
200, -200C, -300, -400, and -500 series airplanes, certificated in
any category.
(2) Installation of Supplemental Type Certificate (STC)
ST01219SE (http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/2C6E3DBDDD36F91C862576A4005D64E2?OpenDocument&Highlight=st01219se)
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 57, Wings.
(e) Unsafe Condition
This AD was prompted by reports of cracks found in the aft
support fitting, the rear spar upper chord, and the rear spar web.
We are issuing this AD to detect and correct cracking of the aft
support fitting for the main landing gear (MLG) beam, and the rear
spar upper chord and rear spar web in the area of rear spar station
(RSS) 224.14, which could grow and result in a fuel leak and
possible fire.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
