Airworthiness Directives; Airbus SAS Airplanes

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

The FAA is superseding Airworthiness Directive (AD) 2017-10-17, which applied to certain Airbus SAS Model A330-200; A330-200 Freighter; and A330-300 series airplanes. AD 2017-10-17 required revising the existing maintenance or inspection program, as applicable, to incorporate new fuel airworthiness limitations. This AD was prompted by a determination that new or more restrictive fuel airworthiness limitations and tasks are necessary. This AD continues to require the actions in AD 2017-10-17 and requires revising the existing maintenance or inspection program, as applicable, to incorporate additional new or more restrictive fuel airworthiness limitations and tasks, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also expands the applicability to include additional airplane models. The FAA is issuing this AD to address the unsafe condition on these products.

DATES:

This AD is effective December 21, 2022.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of December 21, 2022.

The Director of the Federal Register approved the incorporation by reference of a certain other publication listed in this AD as of June 29, 2017 (82 FR 24017, May 25, 2017).

SUPPLEMENTARY INFORMATION:

Background

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2017-10-17, Amendment 39-18891 (82 FR 24017, May 25, 2017) (AD 2017-10-17). AD 2017-10-17 applied to certain Airbus SAS Model A330-223F and -243F airplanes; Model A330-201, -202, -203, -223, and -243 airplanes; Model A330-301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes. AD 2017-10-17 required revising the existing maintenance or inspection program, as applicable, to include new fuel airworthiness limitations. The FAA issued AD 2017-10-17 to address the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.

The NPRM published in the Federal Register on June 10, 2022 (87 FR 35465). The NPRM was prompted by AD 2021-0252, dated November 17, 2021, issued by EASA (referred to after this as the MCAI). The MCAI states that new or more restrictive fuel airworthiness limitations and tasks are necessary.

You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA-2022-0673.

In the NPRM, the FAA proposed to continue to require the actions in AD 2017-10-17. The NPRM also proposed to require revising the existing maintenance or inspection program, as applicable, to incorporate additional new or more restrictive fuel airworthiness limitations and tasks, as specified in EASA AD 2021-0252. In addition, the NPRM proposed to expand the applicability to include additional models. The FAA is issuing this AD to address the unsafe condition on these products.

Discussion of Final Airworthiness Directive

Comments

The FAA received comments from the Air Line Pilots Association, International (ALPA) who supported the NPRM without change.

Conclusion

This product has been approved by the aviation authority of another country and is approved for operation in the United States. Pursuant to the FAA's bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA reviewed the relevant data, considered the comment received, and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator.

Related Service Information Under 1 CFR Part 51

EASA AD 2021-0252 describes new or more restrictive fuel airworthiness limitations and tasks.

This AD also requires Airbus A330 Airworthiness Limitations Section (ALS) Part 5—Fuel Airworthiness Limitations (FAL), Revision 01, dated October 28, 2015, which the Director of the Federal Register approved for incorporation by reference as of June 29, 2017 (82 FR 24017, May 25, 2017).

This material 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

The FAA estimates that this AD affects 138 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD:

The FAA estimates the total cost per operator for the retained actions from AD 2017-10-17 to be $7,650 (90 work-hours × $85 per work-hour).

The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 work-hours per operator, although the agency recognizes that this number may vary from operator to operator. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate.

The FAA estimates the total cost per operator for the new actions to be $7,650 (90 work-hours × $85 per work-hour).

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.

The FAA is 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) Will not affect intrastate aviation in Alaska, 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.
