The FAA is revising an existing airworthiness directive (AD), which applies to all Airbus Model A300-600 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 caused by latent failures, alterations, repairs, or maintenance actions, could result in fuel tank explosions and consequent loss of the airplane.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of December 28, 2009.
On June 27, 2007 (72 FR 28827, May 23, 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 25, 2010.

On May 7, 2007, we issued AD 2007-10-10, Amendment 39-15051 (72 FR 28827, May 23, 2007). That AD applied to all Airbus Model A300-600 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.
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.
AD 2007-10-10 cites Airbus A300-600 Fuel Airworthiness Limitations, Document 95A.1929/05, Issue 1, dated December 19, 2005. Since we issued that AD, Airbus has revised the referenced service information and issued Airbus A300-600 Fuel Airworthiness Limitations, Document 95A.1929/05, Issue 2, dated May 16, 2007. The revised service information clarifies the new limitations for fuel tank systems, but adds no new procedures. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.
The affected products 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.
This revision imposes no additional economic burden. The current costs for this AD are repeated for the convenience of affected operators, as follows:
This AD affects about 138 airplanes of U.S. registry. The required actions take about 2 work hours per airplane, at an average labor rate of $80 per work hour. Based on these figures, the estimated cost of the AD for U.S. operators is $22,080, or $160 per airplane.
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.
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-2009-1114; Directorate Identifier 2009-NM-157-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 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 Start Printed Page 65400safety 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.
Accordingly, under the authority delegated to me by the Administrator, the FAA amends part 39 of the Federal Aviation Regulations (
2. The FAA amends § 39.13 by removing Amendment 39-15051 (
AD 2007-10-10 R1 Airbus: Amendment 39-16134. Docket No. FAA-2009-1114; Directorate Identifier 2009-NM-157-AD.
(a) This airworthiness directive (AD) is effective December 28, 2009.
(b) This AD revises AD 2007-10-10, Amendment 39-15051.
(c) This AD applies to all Airbus Model A300-600 series airplanes, certificated in any category.
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 the 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 (j) 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.
(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 caused by latent failures, alterations, repairs, or maintenance actions, could result in fuel tank explosions and consequent loss of the airplane.
(f) Within 3 months after June 27, 2007 (the effective date of AD 2007-10-10), revise the ALS of the Instructions for Continued Airworthiness to incorporate Airbus A300-600 ALS Part 5—Fuel Airworthiness Limitations, dated May 31, 2006, as defined in Airbus A300-600 Fuel Airworthiness Limitations, Document 95A.1929/05, Issue 1, dated December 19, 2005 (approved by the European Aviation Safety Agency (EASA) on March 13, 2006), Section 1, “Maintenance/Inspection Tasks” (hereafter referred to as Section 1 of Issue 1 of Document 95A.1929/05); or Airbus A300-600 Fuel Airworthiness Limitations, Document 95A.1929/05, Issue 2, dated May 16, 2007, Section 1, “Maintenance/Inspection Tasks” (hereafter referred to as “Section 1 of Issue 2 Document 95A.1929/05”).
