Airworthiness Directives; Airbus Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to supersede Airworthiness Directive (AD) 2007-10-
10 R1, for all Airbus Model A300 B4-600, B4-600R, and F4-600R series
Page 1574
airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). AD 2007-10-10 R1 currently requires revising the airworthiness limitations section (ALS) of the instructions for continued airworthiness (ICA) to incorporate new limitations for fuel tank systems. Since we issued AD 2007-10-10 R1, the manufacturer has issued more restrictive maintenance requirements and/or airworthiness limitations. This proposed AD would require revising the maintenance program or inspection program to incorporate revised fuel maintenance and inspection tasks. We are proposing 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.

Discussion
On December 2, 2009, we issued AD 2007-10-10 R1, Amendment 39-16134 (74 FR 65398, December 10, 2009). AD 2007-10-10 R1 requires actions intended to address an unsafe condition on all Airbus Model A300 B4-
600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes).
Since we issued AD 2007-10-10 R1, Amendment 39-16134 (74 FR 65398, December 10, 2009), we have determined more restrictive maintenance requirements and airworthiness limitations are necessary.
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2014-0194, dated October 15, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). The MCAI states:
Prompted by an accident * * *, the Federal Aviation Administration (FAA) published Special Federal Aviation Regulation (SFAR) 88, http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgFAR.nsf/0/EEFB3F94451DC06286256C93004F5E07?OpenDocument&Highlight=sfar 88, and the Joint Aviation Authorities (JAA) published Interim Policy INT/POL/25/12. In response to these regulations, Airbus conducted a design review to develop Fuel Airworthiness Limitations (FAL) for Airbus on A300-600 and A300-600ST aeroplanes.
The FAL were specified in Airbus A300-600 FAL document ref. 95A.1929/05 at issue 02 and in the A300-600 Airworthiness Limitation Section ALS variation to FAL document issue 02 ref. 0CVLG110007/C0S issue 01, for A300-600 and A300-600ST aeroplanes.
EASA issued EASA AD 2006-0201 to require compliance with the FAL documents (comprising maintenance/inspection tasks and Critical Design Configuration Control Limitations (CDCCL)).
EASA AD 2006-0201 was superseded by EASA AD 2007-0095 (later revised) which corresponds to FAA AD 2007-10-10 R1, Amendment 39-
16134 (74 FR 65398, December 10, 2009), which retained the original requirements and corrected and updated the compliance paragraphs concerning task ref. 28-18-00-03-1 and CDCCL's.
Since EASA AD 2007-0095R1 was published, Airbus issued A300-600 ALS Part 5, prompted by EASA policy statement (EASA D2005/CPRO) which requests design approval holders to integrate Fuel Tank Safety items into an ALS document. The A300-600 ALS Part 5 is approved by EASA.
Failure to comply with the items as identified in Airbus A300-
600 ALS Part 5 could result in a fuel tank explosion and consequent loss of the aeroplane.
For the reasons described above, this EASA AD retains the requirements of EASA AD 2007-0095R1, which is superseded, and requires implementation of the new and more restrictive maintenance instructions and/or airworthiness limitations as specified in Airbus A300-600 ALS Part 5.
The unsafe condition is 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. You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-
8427.
Related Service Information Under 1 CFR Part 51
Airbus has issued A300-600 Airworthiness Limitations Section), Part
Page 1575
5--Fuel Airworthiness Limitations, Revision 00, dated May 27, 2014. The airworthiness limitations introduce mandatory instructions and more restrictive maintenance requirements. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section of this NPRM.
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design.
This proposed AD would require revisions to certain operator maintenance documents to include new actions (e.g., inspections and/or critical design configuration Control Limitations (CDCCLs). Compliance with these actions 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, 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 (k) of this AD. The request should include a description of changes to the required actions that will ensure the continued operational safety of the airplane.
Notwithstanding any other maintenance or operational requirements, components that have been identified as airworthy or installed on the affected airplanes before accomplishment of the revision of the airplane maintenance or inspection program specified in this AD, do not need to be reworked in accordance with the CDCCLs. However, once the airplane maintenance or inspection program has been revised as required by this AD, future maintenance actions on these components must be done in accordance with the CDCCLs.
Differences Between This Proposed AD and the MCAI or Service Information
The MCAI specifies that if there are findings from the ALS inspection tasks, corrective actions must be accomplished in accordance with Airbus maintenance documentation. However, this AD does not include that requirement. Operators of U.S.-registered airplanes are required by general airworthiness and operational regulations to perform maintenance using methods that are acceptable to the FAA. We consider those methods to be adequate to address any corrective actions necessitated by the findings of ALS inspections required by this AD.
This proposed AD would require operators to revise the maintenance or inspection program within 3 months after the effective date of this AD to incorporate revised fuel maintenance and inspection tasks. The MCAI specifies compliance with the tasks as of the effective date of the MCAI. In developing the compliance time for this action, we considered the degree of urgency associated with addressing the unsafe condition. We find 3 months an appropriate compliance time to complete these actions. This difference has been coordinated with the EASA.
Costs of Compliance
We estimate that this proposed AD affects 122 airplanes of U.S. registry.
The actions required by AD 2007-10-10 R1, Amendment 39-16134 (74 FR 65398, December 10, 2009), and retained in this proposed AD take about 2 work-hours per product, at an average labor rate of $85 per work-
hour. Based on these figures, the estimated cost of the actions that are required by AD 2007-10-10 R1 is $170 per product.
We also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost $0 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $10,370, or $85 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
We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed 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);
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
