AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Airbus model series airplanes listed above. This AD requires revising the Airworthiness Limitations Section of the Instructions for
Continuing Airworthiness to incorporate new fuel system limitations for airplanes modified in accordance with Supplemental Type Certificate
(STC) ST00092BO. This AD also requires a general visual inspection for tank unit separation and compensator separation of the center, inner, and outer fuel tanks, and trim fuel tanks of the tank units, and corrective actions if necessary. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent a potential of ignition sources inside fuel tanks, which in combination with flammable fuel vapors, could result in a fuel tank fire or explosion and consequent loss of the airplane.
DATES: This AD is effective December 1, 2009.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of December 1, 2009.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to certain Airbus Model A300 B4-601, B4-603, B4-605R, B4-620, B4-622, B4- 622R, F4-605R, F4-622R, and C4-605R Variant F series airplanes. That
NPRM was published in the Federal Register on April 9, 2009 (74 FR 16152). That NPRM proposed to require revising the Airworthiness
Limitations Section (ALS) of the Instructions for Continuing
Airworthiness to incorporate new fuel system limitations for airplanes modified in accordance with Supplemental Type Certificate (STC)
ST00092BO. That NPRM also proposed to require a general visual inspection for tank unit separation and compensator separation of the center, inner, and outer fuel tanks, and trim fuel tanks of
Page 55117
the tank units, and corrective actions if necessary.
Comments
We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public.
Actions Since NPRM Was Issued
Since we issued that NPRM, 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.
We have added Note 2 to this AD to clarify the intended effect of the AD on spare and on-airplane fuel tank system components.
Revision to Paragraph (h) of This AD
We removed a redundant reference to the service information, ``in accordance with Section 2.2.3 of the Goodrich A300-600 Instructions for
Continued Airworthiness, Document T3012-0005-0101, Revision B, dated
June 12, 2008,'' from paragraph (h) of this AD.
Revision to the Product Identification Line
We have revised the product identification line that precedes paragraph (a) of this AD to specify Airbus. For ADs that apply to STCs installed on only one type of airplane, we identify the name of the airplane manufacturer in the product identification line.
Revision to Paragraph (l) of this AD
We have revised paragraph (l) of this AD to include the phrase,
``if done before the effective date of this AD.'' This text was inadvertently omitted. It was our intention to provide credit for operators which have completed the inspections specified in paragraph
(h) of this AD, before the effective date of this AD, using Goodrich
Service Bulletin 300723-0101-28-01, Revision 1, dated July 1, 2004.
Conclusion
We reviewed the relevant data, and determined that air safety and the public interest require adopting the AD with the changes described previously. We also determined that these changes will not increase the economic burden on any operator or increase the scope of the AD.
Costs of Compliance
We estimate that this AD affects 68 airplanes of U.S. registry. We also estimate that it takes about 8 work-hours per product to comply with this AD. The average labor rate is $80 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $43,520, or $640 per product.
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), 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.
You can find our regulatory evaluation and the estimated costs of compliance in the AD Docket.
