2020-03966. Airworthiness Directives; Airbus SAS Airplanes

AGENCY:

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

ACTION:

Final rule.

SUMMARY:

The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A321-211, -212, -213, -231, and -232 airplanes. This AD was prompted by a report of erroneous positioning of affected parts on the skin of the fuselage during the pre-drill phase, which could result in unwanted drill-starts. This AD requires inspections for the presence of unwanted drill-starts on affected parts, and an inspection for cracks and corrective action if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

DATES:

This AD is effective April 2, 2020.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of April 2, 2020.

SUPPLEMENTARY INFORMATION:

Discussion

The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019-0098, dated May 3, 2019 (“EASA AD 2019-0098”) (also referred to as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Airbus SAS Model A321-211, -212, -213, -231, and -232 airplanes.

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus SAS Model A321-211, -212, -213, -231, and -232 airplanes. The NPRM published in the Federal Register on October 28, 2019 (84 FR 57657). The NPRM was prompted by a report of erroneous positioning of affected parts (internal upper doublers of the forward emergency exit doors (#2 position), left-hand and right-hand sides) on the skin of the fuselage during the pre-drill phase, which could result in unwanted drill-starts. The NPRM proposed to require inspections for the presence of unwanted drill-starts on affected parts, and an inspection for cracks and corrective action if necessary.

The FAA is issuing this AD to address unwanted drill-starts, which could affect the fatigue properties of affected fuselage skin parts and possibly result in cracking of fuselage skin. See the MCAI for additional background information.

Comments

The FAA gave the public the opportunity to participate in developing this final rule. The FAA has considered the comment received. An anonymous person stated support for the NPRM.

Change Made to This Final Rule

EASA AD 2019-0098, which is referenced in paragraph (g) of this AD, specifies to report inspection results to Airbus within a certain compliance time. The FAA has added paragraph (h)(3) to this AD to clarify the compliance times for the reporting required by this AD.

Conclusion

The FAA reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this final rule with the change described previously and minor editorial changes. The FAA has determined that these 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.

The FAA also determined that these changes will not increase the economic burden on any operator or increase the scope of this final rule.

Related IBR Material Under 1 CFR Part 51

EASA AD 2019-0098 describes procedures for inspections for the presence of unwanted drill-starts on affected parts (internal upper doublers of the forward emergency exit doors (#2 position), left-hand and right-hand sides), high frequency eddy current (HFEC) inspections for cracks, and corrective actions including repair of cracked parts. 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 51 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD:

Estimated Costs for Required Actions

Labor cost	Parts cost	Cost per product	Cost on U.S. operators
Up to 73 work-hours × $85 per hour = Up to $6,205	$0	Up to $6,205	Up to $316,455.

The FAA estimates that it would take about 1 work-hour per product to comply with the reporting requirement in this AD. The average labor rate is $85 per hour. Based on these figures, the FAA estimates the cost of reporting the inspection results on U.S. operators to be $4,335, or $85 per product.

The FAA estimates the following costs to do any necessary on-condition action that would be required based on the results of any required actions. The FAA has no way of determining the number of aircraft that might need this on-condition action:

Estimated Costs of On-Condition Actions

Labor cost	Parts cost	Cost per product
93 work-hours × $85 per hour = $7,905	$4,300	$12,205

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 Information Collection Clearance Officer, Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177-1524.

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.
