Airworthiness Directives; Airbus Model A300 B2-1C, B2-203, B2K-3C, B4-103, B4-203, B4-2C Airplanes; Model A310 Series Airplanes; and Model A300 B4-601, B4-603, B4-605R, B4-620, B4-622, and B4-622R Airplanes

Summary:

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

Cracks have been found on pylon side panels (upper section) at rib 8 on Airbus A300, A310 and A300-600 aircraft equipped with General Electric engines. Investigation of these findings indicates that this problem is likely to affect aircraft of this type design with other engine installations. This condition, if not corrected, can lead to reduced strength [structural integrity] of the pylon primary structure.

* * * * *

The unsafe condition is reduced structural integrity of the pylon primary structure, which could cause detachment of the engine from the fuselage. We are issuing this AD to require actions to correct the unsafe condition on these products.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on September 21, 2009 (74 FR 48024). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

Cracks have been found on pylon side panels (upper section) at rib 8 on Airbus A300, A310 and A300-600 aircraft equipped with General Electric engines. Investigation of these findings indicates that this problem is likely to affect aircraft of this type design with other engine installations. This condition, if not corrected, can lead to reduced strength [structural integrity] of the pylon primary structure.

In order to detect any crack propagation at an early stage, thus avoiding an extensive repair, Airbus issued Service Bulletins (SB) A300-54-0075, A310-54-2018 and A300-54-6015. * * *

This AD requires the implementation of this * * * inspection programme.

The unsafe condition is reduced structural integrity of the pylon primary structure, which could cause detachment of the engine from the fuselage. Required actions include repetitive detailed visual inspections, or repetitive eddy current and detailed visual inspections, to detect cracks, depending on the airplane configuration, and corrective actions if necessary. The corrective actions include repairing the cracking, and contacting Airbus for repair instructions and doing the repair, as applicable. You may obtain further information by examining the MCAI in the AD docket.

Comments

We gave the public the opportunity to participate in developing this AD. We considered the comments received.

Request To Clarify Reporting Requirement

American Airlines requests that we remove the requirement for reporting findings to Airbus. The commenter states that Appendix 1, 2, and 3 in Airbus Service Bulletin A300-54-6015 require findings to be reported; however, the proposed rule specifically excludes Appendix 1, 2, and 3 in Table 2 of this AD. American Airlines states the difference is not addressed in the proposed rule. The commenter also states that reporting findings within a specified time period has no effect on improving safety and should not be mandated by the proposed rule.

We agree that reporting inspection findings to Airbus is not necessary in this AD for the reasons stated by the commenter. Since the MCAI requires reporting inspection findings to Airbus and it is not our intent to require those reports, we have added Note 2 in this AD to clarify that this AD does not include a reporting requirement.

Request To Refer to Paragraph 3.B. in Airbus Mandatory Service Bulletin A300-54-6015, Revision 02, Dated June 26, 2008, for Inspection Task

The commenter, R. L. Vernon, requests that paragraph (f)(1) of the NPRM refer to paragraph 3.B. of Airbus Mandatory Service Bulletin A300-54-6015, Revision 02, dated June 26, 2008, rather than paragraph 3.E., for the inspection task. The commenter statesthat paragraph 3.E. incorrectly calls for the access panels to be removed, rather than installed.

We concur with the request to refer to paragraph 3.B of Airbus Mandatory Service Bulletin A300-54-6015, Revision 02, dated June 26, 2008. It appears there is a typographical error in paragraph 3.E. of Airbus Mandatory Service Bulletin A300-54-6015, Revision 02, dated June 26, 2008, which instructs operators to remove access panels rather than to install access panels. We have revised paragraph (f) of this AD to refer to the specific section of the Accomplishment Instructions of Airbus Mandatory Service Bulletin A300-54-6015, Revision 02, dated June 26, 2008, for that action. We have also revised paragraphs (f)(4) and (f)(7) of this AD to refer to paragraph 3.C. rather than paragraph 3.B. of the Accomplishment Instructions.

Request To Extend Grace Period

FedEx requests that the grace period for the inspection to detect cracking be extended from 250 flight cycles to 350 flight cycles. FedEx states the inspection threshold/grace periods do not fit into their planned scheduled maintenance checks. FedEx states that 61 of 95 affected airplanes have exceeded the AD compliance threshold, and thus will be subject to the grace period of 250 flight cycles. FedEx states that the grace period of 250 flight cycles does not allow all airplanes to be inspected at a B-check (every 500 flight hours), thereby requiring the airplanes to be inspected at a special visit.

We do not agree with the request to extend the grace period. An extension to the grace period cannot be provided easily and depends on the airplane and structure configuration, as well as the number of flight cycles and flight hours accumulated from repair embodiment or from first flight. Under the provisions of paragraph (g)(1) of the final rule, we will consider requests for approval of an extension of the grace period if sufficient data are submitted to substantiate that the new grace period would provide an acceptable level of safety. We have not changed the AD in this regard.

Request for Clarification of Table 1 of the NPRM

FedEx requests that the compliance times listed in Table 1 of the NPRM be written more clearly. FedEx states that the 18,000-flight-cycle criterion appears to be arbitrary and adds confusion for the reader. FedEx provides an example that excludes the criterion of 18,000 flight cycles.

We disagree with the request to change Table 1 of the NPRM. The thresholds specified in the second column of that table were derived from the note in the Configuration 01 table in paragraph 1.E.(2) of Airbus Service Bulletin A300-54-6015, Revision 02, dated June 26, 2008. The note states that the inspection is to be done within 2,000 flight cycles without exceeding 20,000 total flight cycles/40,000 total flight hours from first flight. The compliance times specified in Table 1 of this AD reflect the intent of Airbus Mandatory Service Bulletin A300-54-6015, Revision 02, dated June 26, 2008. We have not changed the AD in this regard.

Conclusion

We reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We determined that these changes will not increase the economic burden on any operator or increase the scope of the AD.

Differences Between This AD and the MCAI or Service Information

We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information.

We might also have required different actions in this AD from those in the MCAI in order to follow our FAA policies. Any such differences are highlighted in a NOTE within the AD.

Explanation of Change of Costs of Compliance

Since issuance of the original NPRM, we have increased the labor rate used in the Costs of Compliance from $80 per work-hour to $85 per work-hour. The Costs of Compliance information, below, reflects this increase in the specified hourly labor rate.

Costs of Compliance

We estimate that this AD will affect 230 products of U.S. registry. We also estimate that it will take about 4 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $78,200, or $340 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 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 this AD:

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.

Examining the AD Docket

You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647-5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

Subject

(d) Air Transport Association (ATA) of America Code 54: Nacelles/Pylons.

Reason

(e) The mandatory continuing airworthiness information (MCAI) states:

“Cracks have been found on pylon side panels (upper section) at rib 8 on Airbus A300, A310 and A300-600 aircraft equipped with General Electric engines. Investigation of these findings indicates that this problem is likely to affect aircraft of this type design with other engine installations. This condition, if not corrected, can lead to reduced strength [structural integrity] of the pylon primary structure.

“In order to detect any crack propagation at an early stage, thus avoiding an extensive repair, Airbus issued Service Bulletins (SB) A300-54-0075, A310-54-2018 and A300-54-6015. * * *

“This AD requires the implementation of this * * * inspection programme.”

The unsafe condition is reduced structural integrity of the pylon primary structure, which could cause detachment of the engine from the fuselage. Required actions include repetitive detailed visual inspections, or repetitive eddy current and detailed visual inspections, to detect cracks, depending on the airplane configuration, and corrective actions if necessary. The corrective actions include repairing the cracking, and contacting Airbus for repair instructions and doing the repair, as applicable.

Actions and Compliance

FAA AD Differences

Note 1:

This AD differs from the MCAI and/or service information as follows:

(1) Although the MCAI/service information allows further flight after cracks are found during compliance with certain actions, this AD requires that you repair the crack(s) before further flight.

(2) Although the MCAI specifies to send all inspection results to Airbus, this AD does not include that requirement.

Other FAA AD Provisions

(g) The following provisions also apply to this AD:

(1)Alternative Methods of Compliance (AMOCs): The Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal maintenance inspector (PMI) or principal avionics inspector (PAI), as appropriate, or lacking a principal inspector, your local Flight Standards District Office. The AMOC approval letter must specifically reference this AD.

(2)Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service.

(3)Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501et seq.), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.
