Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Airbus Model A300 series airplanes; 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); and Model A310 series airplanes. The NPRM published in the Federal Register on February 17, 2017 (82 FR 10968) (“the NPRM”). The NPRM was intended to complete certain mandated programs intended to support the airplane reaching its limit of validity (LOV) of the engineering data that support the established structural maintenance program. The NPRM proposed to require inspecting the forward passenger doors to identify the part number, and for affected doors, inspecting to identify existing repairs and doing corrective actions if necessary. We are issuing this AD to detect and correct widespread fatigue damage of the forward passenger doors, which could result in reduced structural integrity of the airplane.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2016-0079, dated April 21, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for all Airbus Model A300 series airplanes; 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); and Model A310 series airplanes. The MCAI states:

In the frame of the “Ageing Aeroplane Safety Rule Project”, a review of the A300, A300-600 and A310 Structural Repair Manuals (SRMs) was performed against Fatigue and Damage Tolerance criteria to satisfy the ageing aeroplane regulation.

As a result of this review, some repairs concerning the forward passenger door flanges were identified as no longer applicable and had to be de-activated. Those repairs may however have been accomplished on some aeroplanes passenger door flanges prior to de-activation of the repair.

This condition, if not detected and corrected, could reduce the structural integrity of the aeroplane.

To address this potential unsafe condition, Airbus issued Service Bulletin (SB) A300-52-0180, SB A300-52-6084 and SB A310-52-2076 to provide inspection instructions.

For the reasons described above, this [EASA] AD requires identification of the forward passenger door part number (P/N) and a one-time Detailed Inspection (DET) of the forward passenger door frame segments inner flanges for SRM repair embodied and, depending on the results from the identification and inspection, accomplishment of corrective action(s) [e.g., repair].

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-2016-9574.

Comments

We gave the public the opportunity to participate in developing this AD. The following presents the comment received on the NPRM and the FAA's response to that comment.

Support for the NPRM

FedEx agrees that the inspection is necessary and supports the intent of the NPRM.

Request To Change the Reporting Requirement

FedEx stated that it does not have a process in place to report the inspection results specified by paragraph (i) of the proposed AD using the on-line Airbus reporting tool. FedEx asked that it be allowed to use the older method of reporting identified in Airbus Service Bulletins A310-52-2076, Revision 01, dated October 14, 2014; and A300-52-6084, Revision 01, dated October 16, 2014. FedEx added that the new on-line application would be used when a method and adequate personnel are in place to utilize that application.

We agree with the commenter. We recognize that operators may not have a method in place or adequate personnel available to utilize the online Airbus reporting tool. Using the reporting sheet provided in Airbus Service Bulletins A310-52-2076, Revision 01, dated October 14, 2014; and A300-52-6084, Revision 01, dated October 16, 2014; is an acceptable method for reporting. We have revised paragraph (i) of this AD to include this option for reporting.

Conclusion

We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this AD with the change described previously and minor editorial changes. We have determined that these minor changes:

  • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
  • Do not add any additional burden upon the public than was already proposed in the NPRM.

We also determined that this change will not increase the economic burden on any operator or increase the scope of this AD.Start Printed Page 27981

Related Service Information Under 1 CFR Part 51

Airbus has issued the following service information:

  • Airbus Service Bulletin A300-52-0180, Revision 01, dated October 14, 2014.
  • Airbus Service Bulletin A310-52-2076, Revision 01, dated October 14, 2014.
  • Airbus Service Bulletin A300-52-6084, Revision 01, dated October 16, 2014.

The service information describes procedures for inspecting the forward passenger doors on the left- and right-hand sides to identify the part number, and for affected doors, inspecting to identify existing repairs and doing corrective actions. These documents are distinct since they apply to different airplane models. 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.

Costs of Compliance

We estimate that this AD affects 128 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:

Estimated Costs

ActionLabor costParts costCost per productCost on U.S. operators
Part number inspection1 work-hour × $85 per hour = $85$0$85$10,880.
Reporting for forward passenger door having P/N A521-71851-000 or P/N A521-71851-0011 work-hour × $85 per hour = $85085Up to $10,880.

We estimate the following costs to do any necessary corrective actions that will be required based on the results of the part number inspection. We have no way of determining the number of airplanes that might need these corrective actions:

On-Condition Costs

ActionLabor costParts costCost per product
Detailed inspection7 work-hours × $85 per hour = $595$0$595

We have received no definitive data that would enable us to provide cost estimates for other on-condition actions specified in this AD.

Paperwork Reduction Act

A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this AD is 2120-0056. The paperwork cost associated with this AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information Collection Clearance Officer, AES-200.

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 that 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);

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.
