14 CFR Part 39

[Docket No. FAA-2015-4202; Directorate Identifier 2014-NM-016-AD; 
Amendment 39-18583; AD 2016-14-02]
RIN 2120-AA64


Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2012-18-12 for 
certain Airbus Model A318, A319, and A320 series airplanes. AD 2012-18-
12 required modifying the off-wing escape slide (OWS) enclosures on the 
left-hand (LH) side and right-hand (RH) side of the fuselage. This new 
AD retains the requirements of AD 2012-18-12 and expands the 
applicability to all Airbus Model A318, A319, and A320 series 
airplanes. This AD was prompted by reports that additional OWS part 
numbers have been affected. We are issuing this AD to prevent off-wing 
exits on the LH and RH sides of the fuselage from becoming inoperative. 
During an emergency, inoperative off-wing exits could impair the safe 
evacuation of occupants, possibly resulting in personal injuries.

DATES: This AD becomes effective August 12, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 12, 
2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of 
October 22, 2012 (77 FR 57003, September 17, 2012).

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2012-18-12, Amendment 39-17189 (77 FR 57003, 
September 17, 2012) (``AD 2012-18-12''). AD 2012-18-12 applied to 
certain Airbus Model A318, A319, and A320 series airplanes. The NPRM 
published in the Federal Register on October 23, 2015 (80 FR 64375) 
(``the NPRM''). The NPRM was prompted by reports that additional OWS 
part numbers have been affected. The NPRM proposed to retain the 
requirements of AD 2012-18-12, and to expand the applicability to all 
Airbus Model A318, A319, and A320 series airplanes. We are issuing this 
AD to prevent off-wing exits on the LH and RH sides of the fuselage 
from becoming inoperative. During an emergency, inoperative off-wing 
exits could impair the safe evacuation of occupants, possibly resulting 
in personal injuries.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0025R1, dated May 26, 2014 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition on all Airbus Model A318, 
A319, and A320 series airplanes. The MCAI states:

    One operator reported a torn out aspirator during scheduled 
deployment (for on ground testing purposes) of the Left Hand (LH) 
off-wing [escape] slide (OWS). Investigation results revealed that 
the aspirator of the OWS system interfered with the extrusion lip of 
the OWS enclosure during the initial stage of the deployment 
sequence.
    This condition, if not corrected, could lead to an off-wing 
exit, either LH or Right Hand (RH), becoming unserviceable, which, 
during an emergency situation, could impair the safe evacuation of 
occupants, possibly resulting in personal injuries.
    To address this potential unsafe condition, Airbus issued 
Service Bulletin (SB) A320-25-1649 containing modification 
instructions for certain part number (P/N) OWS enclosures. 
Consequently, EASA issued [EASA] AD 2010-0210 [http://ad.easa.europa.eu/ad/2010-0210, which corresponds to FAA AD 2012-18-
12] to require modification of the affected OWS enclosures.
    Since that [EASA] AD was issued, several other OWS P/N[s] have 
been identified as potentially impacted.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA AD 2010-0210, which is superseded, expands the 
Applicability to all A318, A319 and A320 aeroplanes, and expands the 
batch of affected P/N[s] prohibited to be installed on an aeroplane.
    For the reason described above, EASA issued AD 2014-0025, 
retaining the requirements of EASA AD 2010-0210, which was 
superseded, expanding the Applicability to all A318, A319 and A320 
aeroplanes, and expanding the batch of affected P/N[s]

[[Page 44490]]

prohibited to be installed on an aeroplane. That [EASA] AD also 
retained the requirements of * * * [an AD, which was superseded], 
which required modification of the OWS and its aspirator.
    This [EASA] AD is revised to amend paragraphs (1) and (3) to 
restore the original applicability of [a Direction 
G[eacute]n[eacute]rale de l'Aviation Civile] DGAC France AD and EASA 
AD 2010-0210, respectively, and to correct paragraph (2) to give 
credit for certain production modifications that were equivalent for 
the in-service actions previously required by [a] DGAC France AD.

    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-2015-
4202.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM and 
the FAA's response to the comment.

Request To Change Parts Installation Prohibitions

    United Airlines (United) asked for clarification of the language in 
paragraph (k) of the proposed AD, which would prohibit the installation 
of OWS part numbers (P/Ns) including D31865-109, D31865-110, D31865-
209, and D31865-210, as identified in paragraph (h)(2) of the proposed 
AD, but also specifies accomplishing the modification required by 
paragraph (g) of the proposed AD. United stated that the modification 
converts those part numbers into D31865-309, D31865-311, D31865-310, 
and D31865-312, respectively. Therefore, United suggested we remove any 
language allowing installation of P/Ns D31865-109, D31865-110, D31865-
209, and D31865-210 from the proposed AD.
    We agree that clarification is necessary. We have moved the 
language in paragraph (h)(1) of the proposed AD into paragraph (h) of 
this AD and removed paragraph (h)(2) from this AD. We have also removed 
the language in paragraph (k) of the proposed AD which specified 
``except as required by paragraph (h)(2) of this AD for the OWS 
enclosures identified in paragraph (h) of this AD.'' And where 
paragraph (l)(2) of the proposed AD referred to ``paragraph (h)(2),'' 
we have changed this reference to paragraph (h) of this AD.

Conclusion

    We reviewed the relevant data, considered the comment 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 minor 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.

Related Service Information Under 1 CFR Part 51

    Airbus has issued the following service information.
     Airbus Service Bulletin A320-25-1156, Revision 03, dated 
December 5, 2001. This service information describes procedures for 
modifying OWS enclosures having P/Ns D31865-101, D31865-102, D31865-
103, D31865-104, D31865-105, D31865-106, D31865-107, or D31865-108 of 
certain Airbus Model A319 and A320 series airplanes.
     Airbus Service Bulletin A320-25-1649, dated February 16, 
2010. This service information describes procedures for modifying and 
installing OWS enclosures having P/Ns D31865-109, D31865-110, D31865-
209, or D31865-210, on the LH and RH sides of the fuselage on certain 
Airbus Model A318, A319, and A320 series airplanes.
    Air Cruisers has issued Service Bulletin A320 004-25-84, Revision 
4, dated November 9, 2012. This service information describes 
procedures for modifying the LH and RH OWS.
    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 ADDRESSES section.

Costs of Compliance

    We estimate that this AD affects 851 airplanes of U.S. registry.
    The actions required by AD 2012-18-12 and retained in this AD take 
about 14 work-hours per product, at an average labor rate of $85 per 
work-hour. Required parts will cost $0 per product. Based on these 
figures, the estimated cost of the actions that are required by AD 
2012-18-12 is $1,190 per product.
    We also estimate that it takes about 48 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts will cost $0 per product. Based on 
these figures, we estimate the cost of this AD on U.S. operators to be 
$3,472,080, or $4,080 per product.

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.

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.
