AD 2018-19-17

We are adopting a new airworthiness directive (AD) for all Airbus SAS Model A300 series airplanes. This AD was prompted by a revision of a certain airworthiness limitations item (ALI) document, which specifies new or more restrictive instructions and airworthiness limitations. This AD requires revising the maintenance or inspection program, as applicable, to incorporate new or revised structural inspection requirements. We are issuing this AD to address the unsafe condition on these products.

Final rule.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec. 39.13 [Amended]

0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD):

2018-19-17 Airbus SAS: Amendment 39-19417; Docket No. FAA-2018-0414; Product Identifier 2017-NM-159-AD.

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 SAS Model A300 series airplanes. The NPRM published in the Federal Register on May 25, 2018 (83 FR 24240). The NPRM was prompted by a revision of a certain ALI document, which specifies new or more restrictive instructions and airworthiness limitations. The NPRM proposed to require revising the maintenance or inspection program, as applicable, to incorporate new or revised structural inspection requirements.
We are issuing this AD to address fatigue cracking, damage, and corrosion in principal structural elements; such fatigue cracking, damage, and corrosion 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 2017-0207, dated October 12, 2017 (referred to after this asthe Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for all Airbus SAS Model A300 series airplanes. The MCAI states:

The airworthiness limitations for the Airbus A300 aeroplanes, which are approved by EASA, are currently defined and published in the Airbus A300 Airworthiness Limitations Section (ALS) documents. The Damage Tolerant Airworthiness Limitation Items are specified in the A300 ALS Part 2. These instructions have been identified as mandatory for continuing airworthiness.
Failure to accomplish these instructions could result in an unsafe condition.
EASA previously issued [EASA] AD 2015-0115 [which corresponds to FAA AD 2017-04-05, Amendment 39-18800 (82 FR 11134, February 21, 2017) (``AD 2017-04-05'')] to require compliance with the maintenance requirements and associated airworthiness limitations defined in Airbus A300 ALS Part 2 Revision 02.
Since that [EASA] AD was issued, new or more restrictive maintenance requirements and airworthiness limitations were approved by EASA. Consequently, Airbus published Revision 03 of the A300 ALS Part 2, compiling all ALS Part 2 changes approved since previous Revision 02.
For the reason described above, this [EASA] AD retains the requirements of EASA AD 2015-0115, which is superseded, and requires accomplishment of the actions specified in Airbus A300 ALS Part 2 Revision 03.

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-2018- 0414.

Comments

We gave the public the opportunity to participate in developing this final rule. We have considered the comment received. Laney Azevedo stated that he supports the NPRM.

Conclusion

We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. We have determined thatthese minor changes:
Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

Airbus SAS has issued Airbus A300 Airworthiness Limitations Section (ALS), Part 2--Damage Tolerant Airworthiness Limitation Items (DT-ALI), Revision 03, dated August 28, 2017. This service information describes airworthiness limitations applicable to the DT-ALI. 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 6 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
We have determined that revising the maintenance or inspection program takes an average of 90 work-hours per operator, although we recognize that this number may vary from operator to operator. In the past, we have estimated that this action takes 1 work-hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), we

[[Page 48208]]

have determined that a per-operator estimate is more accurate than a per-airplane estimate. Therefore, we estimate the total cost per operator to be $7,650 (90 work-hours x $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.
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.
This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes and associated appliances to the Director of the System Oversight Division.

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) 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.
