Discussion
The FAA issued AD 2019-06-09, Amendment 39-19607 (84 FR 14602, April 11, 2019) (``AD 2019-06-09''), which applied to certain Airbus SAS Model A350-941 airplanes. AD 2019-06-09 was prompted by reports that baby bassinet inserts installed on airplane stowages and partitions were found loose because a self-securing fixation device (Loctite) had not been applied. AD 2019-06-09 required repetitive tightness checks of the baby bassinet inserts installed on stowages and partitions and, depending on findings, accomplishment of applicable corrective actions, as specified in an EASA AD, which was incorporated by reference. The FAA issued AD 2019-06-09 to address loose baby bassinet inserts, which, if not detected and corrected, could lead to detachment of a baby bassinet, possibly resulting in injury to the infant or other airplane occupants.
Actions Since AD 2019-06-09 Was Issued
Since AD 2019-06-09 was issued, the FAA has determined that a modification of the baby bassinet inserts installed on stowages and partitions is necessary to address the unsafe condition.
The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019-0115, dated May 28, 2019 (``EASA AD 2019-0115'') (also referred to as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Airbus SAS Model A350-941 airplanes. The MCAI states:
Occurrences were reported where baby bassinet inserts installed on Airbus A350
[[Page 48048]]
aeroplane stowages and on partitions were found loose. Further investigation identified that a self-securing fixation device (Loctite) had not been applied.
This condition, if not detected and corrected, could lead to detachment of a baby bassinet, possibly resulting in injury to the infant or other aeroplane occupants.
To address this potential unsafe condition, Airbus issued the original issue of theAOT [Alert Operators Transmission] to provide inspection instructions. Consequently, EASA issued AD 2018-0271 [which corresponds to FAA AD 2019-06-09] to require repetitive tightness checks of the baby bassinet inserts installed on stowages and partitions and, depending on findings, accomplishment of applicable corrective action(s).
Since that [EASA] AD was issued, Airbus and Diehl Aviation developed the applicable [service bulletin] SB, providing instructions for modification of the baby bassinet inserts installed on stowages and partitions.
For the reasons described above, this [EASA] AD retains the requirements of EASA AD 2018-0271, which is superseded, and requires modification of the baby bassinet inserts installed on stowages and partitions.
Explanation of Retained Requirements
Although this AD does not explicitly restate the requirements of AD 2019-06-09, this AD retains all requirements of AD 2019-06-09. Those requirements are referenced in EASA AD 2019-0115, which, in turn, is referenced in paragraph (g) of this AD.
Related IBR Material Under 1 CFR Part 51
EASA AD 2019-0115 describes procedures for repetitive tightness checks of the baby bassinet inserts installed on stowages and partitions and, depending on findings, accomplishment of applicable corrective actions, and modification of the baby bassinet inserts, which terminates the repetitive tightness checks. 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, and it is publicly available through the EASA website.
FAA's Determination
This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to a bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI referenced above. The FAA is issuing thisAD because the agency evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.
Requirements of This AD
This AD requires accomplishing the actions specified in EASA AD 2019-0115 described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD.
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD process, the FAA initially worked with Airbus and EASA to develop a process to use certain EASA ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has since coordinated with other manufacturers and civil aviation authorities (CAAs) to use this process. As a result, EASA AD 2019-0115 is incorporated by reference in the FAA final rule. This AD, therefore, requires compliance with the provisions specified in EASA AD 2019-0115, through that incorporation, except for any differences identified as exceptions in the regulatory text of this AD. Using common terms that are the same as the heading of a particular section in the EASA AD does not mean that operators need comply only with that section. For example, where the AD requirement refers to ``all required actions and compliance times,'' compliance with this AD requirement is not limited to the section titled ``Required Action(s) and Compliance Time(s)'' in the EASA AD. Service information specified in EASA AD 2019-0115 that is required for compliance with EASA AD 2019-0115 is available on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2019-0672.
FAA's Justification and Determination of the Effective Date
Since there are currently no domestic operators of this product, notice and opportunity for public comment before issuing this AD are unnecessary. In addition, for the reasons stated above, the FAA finds that good cause exists for making this amendment effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight safety, and the FAA did not precede it by notice and opportunity for public comment. The FAA invites you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA-2019-0672; Product Identifier 2019-NM-100-AD'' at the beginning of your comments. The FAA specifically invites comments on the overall regulatory, economic, environmental, and energy aspects of this AD. The FAA will consider all comments received by the closing date and may amend this AD based on those comments.
The FAA will post all comments received, without change, to http://www.regulations.gov, including any personal information you provide. The FAA will also post a report summarizing each substantive verbal contact received about this AD.
Costs of Compliance
Currently, there are no affected U.S.-registered airplanes. If an affected airplane is imported and placed on the U.S. Register in the future, the FAA provides the following cost estimates to comply with this AD:
Estimated Costs for Required Actions ----------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product ---------------------------------------------------------------------------------------------------------------- Retained actions from AD 2019-06-09.... 1 work-hours x $85 per $0 $85.
hour = $85. New actions............................ Up to 3 work-hours x $85 $0 Up to $255.
per hour = Up to $255. ----------------------------------------------------------------------------------------------------------------
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:
[[Page 48049]]
Estimated Costs of On-Condition Actions ------------------------------------------------------------------------
Cost per
Labor cost Parts cost product ------------------------------------------------------------------------ 1 work-hour x $85 per hour = $85...... $0 $85 ------------------------------------------------------------------------
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.
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.
This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. Inaccordance 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
The FAA 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) 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 entitiesunder the criteria of the Regulatory Flexibility Act.
