Airworthiness Directives; Airbus Model A318-111 and -112 Series 
Airplanes, and Model A319, A320, and A321 Series Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is revising an existing airworthiness directive (AD), 
which applies to all Airbus Model A318-111 and -112 series airplanes, 
and all Model A319, A320, and A321 series airplanes. That AD currently 
requires revising the Airworthiness Limitations section of the 
Instructions for Continued Airworthiness to incorporate new limitations 
for fuel tank systems. This AD clarifies the intended effect of the AD 
on spare and on-airplane fuel tank system components. This AD results 
from fuel system reviews conducted by the manufacturer. We are issuing 
this AD to prevent the potential of ignition sources inside fuel tanks, 
which, in combination with flammable fuel vapors, could result in a 
fuel tank explosion and consequent loss of the airplane.

DATES: This AD is effective December 14, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of December 14, 
2009.
    On August 28, 2007 (72 FR 40222, July 24, 2007), the Director of 
the Federal Register approved the incorporation by reference of certain 
other publications listed in the AD.
    We must receive any comments on this AD by January 11, 2010.

SUPPLEMENTARY INFORMATION: 

Discussion

    On July 13, 2007, we issued AD 2007-15-06, Amendment 39-15135 (72 
FR 40222, July 24, 2007). That AD applied to all Airbus Model A318-111 
and -112 series airplanes, and all A319, A320, and A321 series 
airplanes. That AD required revising the Airworthiness Limitations 
section (ALS) of the Instructions for Continued Airworthiness to 
incorporate new limitations for fuel tank systems.
    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 ALS. But once 
the CDCCLs are incorporated into the ALS, future maintenance actions on 
components must be done in accordance with those CDCCLs.

Relevant Service Information

    AD 2007-15-06 cites Airbus A318/A319/A320/A321 Fuel Airworthiness 
Limitations, Document 95A.1931/05, Issue 1, dated December 19, 2005; 
and Airbus A318/A319/A320/A321 ALS Part 5--Fuel Airworthiness 
Limitations, dated February 28, 2006. Since we issued that AD, Airbus 
has revised the referenced service information and issued Airbus A318/
A319/A320/A321 Fuel Airworthiness Limitations, Document 95A.1931/05, 
Issue 2, dated July 8, 2008. The actions described in this service 
information are intended to correct the unsafe condition identified in 
the MCAI.

FAA's Determination and Requirements of This AD

    The affected product(s) have been approved by the aviation 
authority of another country, and are approved for operation in the 
United States. We are issuing this AD because we evaluated all 
pertinent information and determined the unsafe condition exists and is 
likely to exist or develop on other products of the same type design. 
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.

Costs of Compliance

    Based on the service information, we estimate that this AD would 
affect about 720 products of U.S. registry. We also estimate that it 
would take about 2 work-hours per product to comply with the basic 
requirements of this AD. The average labor rate is $80 per work-hour. 
Based on these figures, we estimate the cost of the AD on U.S. 
operators to be $115,200, or $160 per product.

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-2009-1073; Directorate Identifier 2009-NM-174-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.

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.

Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by removing amendment 39-15135 (72 FR 
40222, July 24, 2007) and adding the following new AD:

2007-15-06 R1 Airbus: Amendment 39-16097. Docket No. FAA-2009-1073; 
Directorate Identifier 2009-NM-174-AD.

Effective Date

    (a) This airworthiness directive (AD) is effective December 14, 
2009.

Affected ADs

    (b) This AD revises AD 2007-15-06, Amendment 39-15135.

Applicability

    (c) This AD applies to all Airbus Model A318-111 and -112 
airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -
133 airplanes; Model A320-111, -211, -212, -214, -231, -232, and -
233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -
231, and -232 airplanes; certificated in any category.

    Note 1: This AD requires revisions to certain operator 
maintenance documents to include new inspections and critical design 
configuration control limitations (CDCCLs). Compliance with the 
operator maintenance documents is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired 
in the areas addressed by these inspections and CDCCLs, the operator 
may not be able to accomplish inspections and CDCCLs 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 according to paragraph (i) of this AD. The request should 
include a description of changes to the required inspections and 
CDCCLs that will preserve the critical ignition source prevention 
feature of the affected fuel system.

Unsafe Condition

    (d) This AD results from fuel system reviews conducted by the 
manufacturer. We are issuing this AD to prevent the potential of 
ignition sources inside fuel tanks, 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.
