Federal Register Abstract
The FAA is revising an existing airworthiness directive (AD), which applies to certain Model 737-600, -700, -700C, -800, and -900 series airplanes. That AD currently requires revising the Airworthiness Limitations (AWLs) section of the Instructions for Continued Airworthiness by incorporating new limitations for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. That AD also requires an initial inspection to phase in certain repetitive AWL inspections, and repair if necessary. This AD clarifies the intended effect of the AD on spare and on-airplane fuel tank system components. This AD results from a design review of the fuel tank systems. We are issuing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

SUMMARY: The FAA is revising an existing airworthiness directive (AD),
which applies to certain Model 737-600, -700, -700C, -800, and -900
series airplanes. That AD currently requires revising the Airworthiness
Limitations (AWLs) section of the Instructions for Continued
Airworthiness by incorporating new limitations for fuel tank systems to
satisfy Special Federal Aviation Regulation No. 88 requirements. That
AD also requires an initial inspection to phase in certain repetitive
AWL inspections, and repair if necessary. This AD clarifies the
intended effect of the AD on spare and on-airplane fuel tank system
components. This AD results from a design review of the fuel tank
systems. We are issuing this AD to prevent the potential for ignition
sources inside fuel tanks caused by latent failures, alterations,
repairs, or maintenance actions, which, in combination with flammable
fuel vapors, could result in a fuel tank explosion and consequent loss
of the airplane.

SUPPLEMENTARY INFORMATION:
Discussion
On April 29, 2008, we issued AD 2008-10-10, Amendment 39-15516 (73
FR 25986, May 8, 2008). That AD applied to certain Model 737-600, -700,
-700C, -800, and -900 series airplanes. That AD required revising the
Airworthiness Limitations (AWLs) section of the Instructions for
Continued Airworthiness (ICA) by incorporating new limitations for fuel
tank systems to satisfy Special Federal Aviation Regulation No. 88
requirements. That AD also requires an initial inspection to phase in
certain repetitive AWL inspections, and repair if necessary. That AD
resulted from a design review of the fuel tank systems. The actions
specified in that AD are intended to prevent the potential for ignition
sources inside fuel tanks caused by latent failures, alterations,
repairs, or maintenance actions, which, in combination with flammable
fuel vapors, could result in a fuel tank explosion and consequent loss
of the airplane.
Critical design configuration control limitations (CDCCLs) are
limitation requirements to preserve a critical ignition source
prevention feature of the fuel tank system design that is necessary to
prevent the occurrence of an unsafe condition. The purpose of a CDCCL
is to provide instruction to retain the critical ignition source
prevention feature during configuration change that may be caused by
alterations, repairs, or maintenance actions. A CDCCL is not a periodic
inspection.
Actions Since AD Was Issued
Since we issued that AD, we have determined that it is necessary to
clarify the AD's intended effect on spare and on-airplane fuel tank
system components, regarding the use of maintenance manuals and
instructions for continued airworthiness.
Section 91.403(c) of the Federal Aviation Regulations (14 CFR
91.403(c)) specifies the following:
No person may operate an aircraft for which a manufacturer's
maintenance manual or instructions for continued airworthiness has
been issued that contains an airworthiness limitation section unless
the mandatory * * * procedures * * * have been complied with.
Some operators have questioned whether existing components affected by
the new CDCCLs must be reworked. We did not intend for the AD to
retroactively require rework of components that had been maintained
using acceptable methods before the effective date of the AD. Owners
and operators of the affected airplanes therefore are not required to
rework affected components identified as airworthy or installed on the
affected airplanes before the required revisions of the AWLs. But once
the CDCCLs are incorporated into the AWLs, future maintenance actions
on components must be done in accordance with those CDCCLs.
Relevant Service Information
AD 2008-10-10 cites Boeing Temporary Revision 09-020, dated March
2008, to the Boeing 737-600/700/800/900 Maintenance Planning Data (MPD)
Document, D626A001-CMR. Since we issued that AD, Boeing has revised
Section 9 of the referenced service information. We have reviewed the
revised document. Section 9, Revision September 2009, dated September
2009, of Boeing 737-600/700/800/900 MPD, Document D626A001-CMR, adds no
new procedures in regard to fuel tank safety. We have added paragraph
(l) of this AD to give credit for actions required by paragraphs (g)
and (h) of this AD that were done before the effective date of this AD
in accordance with Section 9, Revision September 2009, dated September
2009, of Boeing 737-600/700/800/900 MPD Document, D626A001-CMR, and the
following earlier revisions: Revision March 2008, Revision April 2008,
Revision June 2008, Revision February 2009, Revision March 2009, and
Revision August 2009.
FAA's Determination and Requirements of This AD
The unsafe condition described previously is likely to exist or
develop on other airplanes of the same type design. For this reason, we
are issuing this AD to revise AD 2008-10-10. This new AD retains the
requirements of the existing AD, and adds a new note to clarify the
intended effect of the AD on spare and on-airplane fuel tank system
components.
Explanation of Additional Changes to AD
AD 2008-10-10 allowed the use of alternative inspections,
intervals, or CDCCLs if they are part of a later revision of the Boeing
737-600/700/800/900 MPD Document, D626A001-CMR, Revision March 2008. AD
2008-10-10 also allowed the use of later revisions of the Boeing 737-
600/700/800/900 MPD Document, D626A001-CMR. Those provisions have been
removed from this AD. Allowing the use of ``a later revision'' or
``later FAA-approved revisions'' of specific service documents violates
Office of the Federal Register regulations for approving materials that
are incorporated by reference. Affected operators, however, may request
approval to use a later revision or an alternative CDCCL, inspection,
or interval, that is part of a later revision of the referenced service
documents as an alternative method of compliance, under the provisions
of paragraph (m) of this AD.
We have revised paragraphs (g)(1), (g)(2), (g)(3), and (h) of this
AD to remove the term ``Revision March 2008 of the MPD,'' which is
defined in paragraph (f) of this AD. We have provided the full document
citation throughout this AD to avoid any confusion about which specific
document is being referenced. However, we have not removed the
``Service Information Reference'' paragraph from this AD. Because this
AD revises AD 2008-10-10, we cannot change paragraph references, which
would adversely affect compliance. Therefore, we have determined that
leaving paragraph (f) of this AD unchanged is a
[[Page 1531]]
less burdensome approach for operators, while still adhering to
standard drafting guidance.
We have revised this AD to identify the legal name of the
manufacturer as published in the most recent type certificate data
sheet for the affected airplane models.
Costs of Compliance
This revision imposes no additional economic burden. The current
costs for this AD are repeated for the convenience of affected
operators, as follows:
There are about 1,960 airplanes of the affected design in the
worldwide fleet. The following table provides the estimated costs, at
an average labor rate of $80 per work hour, for U.S. operators to
comply with this AD.
Estimated Costs

----------------------------------------------------------------------------------------------------------------
FAA's Justification and Determination of the Effective Date
This revision merely clarifies the intended effect on spare and on-
airplane fuel tank system components, and makes no substantive change
to the AD's requirements. For this reason, it is found that notice and
opportunity for prior public comment for this action are unnecessary,
and good cause exists for making this amendment effective in less than
30 days.
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
``Docket No. FAA-2009-1226; Directorate Identifier 2009-NM-149-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 <a href="http://www.regulations.gov">http://www.regulations.gov</a>, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about 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
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 the 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); and
3. 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.

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 Amendment 39-15516 (73 FR
25986, May 8, 2008) and adding the following new AD:
2008-10-10 R1 The Boeing Company: Amendment 39-16164. Docket No.
FAA-2009-1226; Directorate Identifier 2009-NM-149-AD.
Effective Date
(a) This airworthiness directive (AD) is effective January 27,
2010.
Affected ADs
(b) This AD revises AD 2008-10-10, Amendment 39-15516.
Applicability
(c) This AD applies to The Boeing Company Model 737-600, -700, -
700C, -800, and -900 series airplanes, certificated in any category,
with an original standard airworthiness certificate or original
export certificate of airworthiness issued before March 31, 2006.
Note 1: Airplanes with an original standard airworthiness
certificate or original export certificate of airworthiness issued
on or after March 31, 2006, must already be in compliance with the
airworthiness limitations specified in this AD because those
limitations were applicable as part of the airworthiness
certification of those airplanes.
Note 2: This AD requires revisions to certain operator
maintenance documents to include new inspections. Compliance with
these inspections is required by 14 CFR
[[Page 1532]]
91.403(c). For airplanes that have been previously modified,
altered, or repaired in the areas addressed by these inspections,
the operator may not be able to accomplish the inspections described
in the revisions. In this situation, to comply with 14 CFR
91.403(c), the operator must request approval for an alternative
method of compliance (AMOC) according to paragraph (m) of this AD.
The request should include a description of changes to the required
inspections that will ensure the continued operational safety of the
airplane.
Unsafe Condition
(d) This AD results from a design review of the fuel tank
systems. We are issuing this AD to prevent the potential for
ignition sources inside fuel tanks caused by latent failures,
alterations, repairs, or maintenance actions, which, in combination
with flammable fuel vapors, could result in a fuel tank explosion
and consequent loss of the airplane.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
