Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: 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.

Discussion

    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

[[Page 30638]]

in 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 x $85 per     $3,950................  Up to $7,520..........  Up to $11,009,280.
 hour = $3,570.
----------------------------------------------------------------------------------------------------------------

    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 x $85 per              (*)   Up to $1,615.*
 hour = 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.

Regulatory Findings

    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.
