Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2012-23-10, 
which applied to all Airbus Model A318 series airplanes; Model A319 
series airplanes; Model A320-211, -212, -214, -231, -232, and -233 
airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and 
-232 airplanes. AD 2012-23-10 required modifying the affected slide 
rafts. This AD retains the requirements of AD 2012-23-10. This AD also 
requires replacing each escape slide pack assembly having a certain 
part number with a new escape slide pack assembly. This AD was prompted 
by reports of the escape raft inflation system not deploying when 
activated due to the rotation of the cable guide in a direction that 
resulted in jamming of the inflation control cable. We are issuing this 
AD to address the unsafe condition on these products.

DATES: This AD is effective January 16, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of January 16, 
2018.
    The Director of the Federal Register approved the incorporation by

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2012-23-10, Amendment 39-17266 (77 FR 70369, 
November 26, 2012) (``AD 2012-23-10''). AD 2012-23-10 applied to all 
Airbus Model A318 series airplanes; Model A319 series airplanes; Model 
A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321-
111, -112, -131, -211, -212, -213, -231, and -232 airplanes. The NPRM 
published in the Federal Register on June 23, 2017 (82 FR 28599). The 
NPRM was prompted by reports of the escape raft inflation system not 
deploying when activated due to the rotation of the cable guide in a 
direction that resulted in jamming of the inflation control cable.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2016-0043, dated March 4, 2016 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for all Airbus Model A318, A319, A320, and A321 series 
airplanes. The MCAI states:

    Two occurrences were reported on Airbus A320 family aeroplanes 
where the escape slide raft inflation system did not deploy when 
activated. This was due to the rotation of the cable guide in a 
direction, which resulted in jamming of the inflation control cable. 
Additionally, one case was reported where the system did not deploy 
properly due to a cracked inflation hose fitting. Investigation 
conducted by Air Cruisers Company [Zodiac Aero Evacuation Systems], 
the slide raft manufacturer, showed that the hose fitting could be 
subject to a bending moment, if improperly packed. Consequently, the 
hose fitting could separate from the reservoir and the inflation of 
the slide raft would be impaired.
    This condition, if not corrected, could delay the evacuation 
from the aeroplane in case of emergency, possibly resulting in 
injury to the occupants.
    To address this potential unsafe condition, DGAC France issued 
AD F-2004-072 [which correlates with FAA AD 2004-26-07, Amendment 
39-13919 (70 FR 1176, January 6, 2005)], to introduce an inflation 
hose retainer preventing an incomplete inflation of emergency escape 
slides, which could delay passenger evacuation, and EASA issued AD 
2011-0160 (later revised twice) to require modification of the 
affected slide rafts or replacement thereof with modified units.
    Since EASA AD 2011-0160R2 [which correlates with FAA AD 2012-23-
10 and was issued as a stand-alone, non-superseding AD] was issued, 
Air Cruisers [Zodiac Aero Evacuation Systems] developed a 
modification of the slide and slide/raft, part of the escape slide 
pack assemblies, to improve its deployment. Modified slides and 
slide/rafts are identified by a different Part Number (P/N); 
consequently, also the escape slide pack assemblies are identified 
by a different P/N.
    For the reasons described above, this [EASA] AD retains the 
requirements of DGAC France AD F-2004-072 (EASA approval 2004-5335) 
and EASA AD 2011-0160R2, which are superseded, and requires 
installation of modified escape slide pack assemblies.
    Appendix 1 of this [EASA] AD provides a comprehensive list of 
escape slide pack assemblies P/N that, at the issue date of the 
[EASA] AD, are not approved for further installation on any 
aeroplane.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA 2017-
0556.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments

[[Page 58103]]

received on the NPRM and the FAA's response to each comment. The Air 
Line Pilots Association, International supported the NPRM.

Request To Extend the Compliance Time

    United Airlines (UAL) requested that the compliance time in the 
proposed AD be extended from 36 months to 42 months. UAL stated that 
this will allow sufficient time to purge the stock and order parts from 
the supplier.
    We disagree with the commenter's request. UAL has not provided 
suitable rationale to justify that extending the compliance time will 
ensure the safety of the affected fleet. In developing the appropriate 
compliance time for this action, we considered the safety implications, 
parts availability, and normal maintenance schedules for timely 
accomplishment of this modification. We have determined that 36 months 
will ensure an acceptable level of safety and provide sufficient time 
to order parts and accomplish the required modification. We have not 
changed this AD in this regard.

Request To Allow Interchangeable Parts

    Delta Airlines (DAL) requested an allowance for interchangeable 
parts. DAL stated that paragraph (l) of the proposed AD specifies the 
replacement of ``old'' escape slide packs with corresponding ``new'' 
escape slide packs. DAL stated that paragraph (l) of the proposed AD 
does not allow the replacement of an ``old'' slide pack with an 
alternative ``new'' slide pack that might be fully interchangeable with 
the one that is mandated. DAL commented that, for example, an airplane 
with a part number (P/N) D30664-505 slide pack already installed must 
be replaced with a P/N D30664-705 slide pack. DAL stated that, however, 
P/N D30664-705 and P/N D30664-709 have incorporated Zodiac Aero 
Evacuation Systems Service Bulletin S.B. A320 004-25-96, Revision 1, 
dated September 18, 2015, and are fully interchangeable on DAL 
airplanes. DAL also commented that paragraph (l) of the proposed AD 
limits operational flexibility for accomplishing the intent of the 
NPRM.
    We disagree with the commenter's request because Airbus has defined 
the specific configuration of the pack assemblies that mitigate the 
risk addressed in this AD. We are not aware of any data that 
substantiates the interchanging of those parts referenced in table 1 to 
paragraphs (l), (m)(2), (n)(2), and (o)(1) of this AD, except as 
provided in paragraph (o)(3) of this AD. Operators may request approval 
of an alternative method of compliance (AMOC) supported by appropriate 
substantiating data, under the provisions of paragraph (q)(1) of this 
AD. We have not changed this AD in this regard.

Request for Means of Compliance

    UAL requested that operators be allowed to demonstrate compliance 
by means of a technical records review for the accomplishment of the 
related Zodiac Aero Evacuation Systems service information.
    We contacted UAL to clarify their request. Based on UAL's 
clarification, we concluded that UAL is requesting the accomplishment 
of a records review as an acceptable method for demonstrating 
compliance to the modification of spare parts specified in paragraph 
(m)(2) of this AD. We agree with UAL that a records review can be used 
to verify the modification specified in paragraph (m)(2) of this AD has 
been done as specified in the Zodiac Aero Evacuation Systems service 
information identified in that paragraph. We have not changed this AD 
in this regard.

Request To Use the Latest Service Information

    UAL stated that it would like to highlight that Zodiac Aero 
Evacuation Systems Service Bulletin S.B. A320 004-25-96, Revision 1, 
dated September 18, 2015; and Zodiac Aero Evacuation Systems Service 
Bulletin S.B. A320 004-25-97, Revision 1, dated September 18, 2015, are 
now at Revision 2. UAL also commented that Airbus Service Bulletin 
A320-25-1B82, Revision 01, dated December 10, 2015, is at Revision 2.
    We infer that UAL is requesting that we use the latest service 
information in this AD. We agree with the commenter's request and have 
revised paragraphs (m)(1)(ii) and (m)(2) of this AD accordingly. We 
have also revised paragraph (p) of this AD to give credit for previous 
actions accomplished before the effective date of this AD using earlier 
versions of the service information.

Conclusion

    We reviewed the available data, including the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

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 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 to 
the Director of the System Oversight Division.

Regulatory Findings

    We 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. 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.
