Federal Aviation Administration (FAA), DOT.
Notice of proposed rulemaking (NPRM).
We propose to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A318-112, -121, and -122; A319-111, -112, -115, -131, -132, and -133; A320-214, -216, -232, -233, -251N, and -271N; and A321-211, -212, -213, -231, -232, -251N, -253N, -271N, and -272N airplanes. This proposed AD was prompted by reports of missing or loosened fasteners on connecting brackets of overhead stowage compartments (OHSC) and pivoting OHSC (POHSC). This proposed AD would require modification of the OHSC and POHSC attachments, as specified in a European Aviation Safety Agency (EASA) AD, which will be incorporated by reference. We are proposing this AD to address the unsafe condition on these products.
We must receive comments on this proposed AD by August 12, 2019.

The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019-0069, dated March 28, 2019 (“EASA AD 2019-0069”) (also referred to as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Airbus SAS Model A318-112, -121, and -122; A319-111, -112, -115, -131, -132, and -133; A320-214, -216, -232, -233, -251N, and -271N; and A321-211, -212, -213, -231, -232, -251N, -253N, -271N, and -272N airplanes. The MCAI states:
During routine inspections, several screws were found missing or loose on the interconnecting brackets of certain overhead stowage compartments (OHSC) and pivoting OHSC (POHSC). Investigations and a sampling program have shown that loosening of fasteners can be generated by a relative movement of the OHSC/POHSC and vibrations inside the aeroplane, by elastic deformation of the aeroplane body and by take-off and landing manoeuvres.
This condition, if not corrected, could lead to detachment of an OHSC/POHSC, possibly resulting in injury to aeroplane occupants.
To address this potential unsafe condition, Airbus issued the original issue of the applicable SB [service bulletin], providing modification instructions to improve the robustness of the OHSC and POHSC. Prompted by new findings, the applicable SBs have been later issued, including additional work and associated instructions.
For the reasons described above, this [EASA] AD requires modification of the OHSC and POHSC attachments.
Related IBR Material Under 1 CFR Part 51
EASA AD 2019-0069 describes procedures for modification of the OHSC and POHSC attachments. EASA AD 2019-0069 also describes an inspection for discrepancies (additional work) and corrective actions. The inspection includes checks of the dimensions of the threaded pins against tolerances and checks for damage. Corrective actions include replacing threaded pins and nuts and repairing damage. 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.
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of another country, and is approved for operation Start Printed Page 30638in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design.
Proposed Requirements of This NPRM
This proposed AD would require accomplishing the actions specified in EASA AD 2019-0069 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 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. As a result, EASA AD 2019-0069 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with the provisions specified in EASA AD 2019-0069, through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Service information specified in EASA AD 2019-0069 that is required for compliance with EASA AD 2019-0069 will be available on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2019-0486 after the FAA final rule is published.
Costs of Compliance
We estimate that this proposed AD affects 1,464 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD:
Estimated Costs for Required Actions
|Labor cost||Parts cost||Cost per product||Cost on U.S. operators|
|Up to 42 work-hours × $85 per hour = $3,570||$3,950||Up to $7,520||Up to $11,009,280.|
We estimate the following costs to do any necessary on-condition actions that would be required based on the results of any required or optional actions. We have no way of determining the number of aircraft that might need these on-condition actions:
Estimated Costs of On-Condition Actions
|Labor cost||Parts cost||Cost per product|
|Up to 19 work-hours × $85 per hour = Up to $1,615||(*)||Up to $1,615.*|
|* We have received no definitive data for the on-condition parts costs.|
According to the manufacturer, some or all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all known costs in our 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.
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 proposed 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.
We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation:
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.
