SUPPLEMENTARY INFORMATION: Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021-0291, dated December 22, 2021 (EASA AD 2021-0291) (also referred to as the MCAI), to correct an unsafe condition for all Airbus SAS Model A350-941 and -1041 airplanes. The FAA 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 A350-941 and -1041 airplanes. The NPRM published in the 
                    **Federal Register**
                     on March 31, 2022 (87 FR 18744). The NPRM was prompted by reports that passenger door stop screws were found with missing screw heads. The NPRM proposed to require repetitive general visual inspections (GVI) of each passenger door stop screw for any missing screw heads, and applicable corrective actions, as specified in EASA AD 2021-0291. The FAA is issuing this AD to address missing door stop screw heads, which could result in reduced structural integrity of the airplane. See the MCAI for additional background information. Discussion of Final Airworthiness Directive Comments The FAA received comments from Delta Airlines (DAL). The following presents the comments received on the NPRM and the FAA's response to each comment. Request To Remove the Reporting Requirement DAL requested that the FAA remove the reporting requirement in paragraph (h) of the proposed AD. DAL stated that Note 3 in paragraph (4) of EASA AD 2021-0291 indicates that “[u]sing the inspection report in accordance with the instructions of [the specified service information] is acceptable to comply with the requirements” of paragraph (4). The commenter added that the service information specified in EASA AD 2021-0291 states that the relevant Task (“Complete the Inspection Report Sheet”) specifies that sending the Inspection Report sheet is not an RC (required for compliance) step. The commenter stated that EASA AD 2021-0291, by referencing the service information in Note 3, appears to approve completing the inspection report sheet, but does not require sending the inspection report as it is not required for compliance. The FAA does not agree to the requested change. The inspection reports that are required by this AD will enable the manufacturer to obtain better insight into the nature, cause, and extent of the missing screw heads, and may help the FAA determine whether different AD requirements may be appropriate. Further, EASA AD 2021-0291 requires reporting inspection results to Airbus in paragraph (4) and note 3 is only an option of how to comply with that reporting requirement. This AD has not been changed with regard to this request. Request To Clarify the Timing for Reporting If the FAA does not remove the reporting requirement as DAL requested, DAL recommended revised compliance times for reporting, which DAL asserted would remove restrictive time constraints while still meeting the intent of the proposed AD. Delta stated that commonly the scanned records from each airplane visit are not available until after the end of the visit (when the entire package is sent for scanning all at once), which could take up to 75 days. Delta added that potentially a report due under the conditions of paragraph (h)(3)(ii) of the proposed AD could involve a case where the service information and AD inspections were signed off 20 days into their 75-day long visit but before the AD's effective date, and could result in manual coordination with the Production Control Office. For paragraph (h)(3)(i) of the proposed AD, DAL recommended revising the reporting compliance time as “within 30 days after the end of the maintenance visit/check during which the inspection was performed” instead of “within 30 days after the inspection.”
                For paragraph (h)(3)(ii) of the proposed AD, DAL recommended this paragraph to state “within 30 days after the end of the maintenance visit/check during which the inspection was performed or within 30 days after the effective date of this AD, whichever occurs last” instead of “within 30 days after the effective date of this AD.” The FAA agrees with the request for the reasons provided, and has revised paragraphs (h)(3)(i) and (ii) of this AD accordingly. Conclusion The FAA reviewed the relevant data, considered the comments received, and determined that air safety requires adopting this AD as proposed. Except for minor editorial changes, and any other changes described previously, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Accordingly, the FAA is issuing this AD to address the unsafe condition on these products. Related Service Information Under 1 CFR Part 51 EASA AD 2021-0291 specifies procedures for repetitive general visual 
                    ( print page 39737)
                    inspections (GVI) of each passenger door stop screw for any missing screw heads, and applicable corrective actions. The corrective actions include replacement of the passenger door stop screw, repair, and follow-up actions (GVI of the adjacent door stop area and surrounding structure for damage, including any broken door stop screws). EASA AD 2021-0291 also specifies procedures for reporting results of the initial inspection to Airbus. 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

$18,360* Table does not include estimated costs for reporting.
 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 $2,295, or $85 per product. The FAA estimates the following costs to do any necessary on-condition screw replacement 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

$875 per screw
$960 per screw replacement.
 The FAA has received no definitive data on which to base the cost estimates for the on-condition repairs or applicable follow-up actions specified in this AD. According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all known costs in the cost estimate. 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.
