Federal Register Abstract
We are superseding Airworthiness Directive (AD) 2014-08-01, which applied to all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2014-08-01 required an inspection for part numbers of the interconnecting struts and, for affected interconnecting struts, identification of the part and serial numbers of the associated target and proximity sensors and replacement or re-identification of the flap interconnecting strut if necessary. This AD continues to require an inspection to verify the interconnecting strut part number. This AD also provides a new compliance time and an additional inspection for previously inspected airplanes. This AD was prompted by an investigation that showed that when a certain combination of target/ proximity sensor serial numbers is installed on a flap interconnecting strut, a "target FAR" signal cannot be detected when reaching the mechanical end stop of the interconnecting strut. We are issuing this AD to address the unsafe condition on these products.

ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are superseding Airworthiness Directive (AD) 2014-08-01,
which applied to all Airbus Model A318, A319, A320, and A321 series
airplanes. AD 2014-08-01 required an inspection for part numbers of the
interconnecting struts and, for affected interconnecting struts,
identification of the part and serial numbers of the associated target
and proximity sensors and replacement or re-identification of the flap
interconnecting strut if necessary. This AD continues to require an
inspection to verify the interconnecting strut part number. This AD
also provides a new compliance time and an additional inspection for
previously inspected airplanes. This AD was prompted by an
investigation that showed that when a certain combination of target/
proximity sensor serial numbers is installed on a flap interconnecting
strut, a ``target FAR'' signal cannot be detected when reaching the
mechanical end stop of the interconnecting strut. We are issuing this
AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2014-08-01, Amendment 39-17825 (79 FR 23900,
April 29, 2014) (``AD 2014-08-01''). AD 2014-08-01 applied to all
Airbus Model A318, A319, A320, and A321 series airplanes. The NPRM
published in the Federal Register on May 19, 2017 (82 FR 22918).
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA AD
2016-0113, dated June 15, 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:
The flap interconnecting strut is a safety device of the High
Lift System which acts as an alternative load path from one flap
surface to another in case of a flap drive system disconnection. In
such a failure case, the installed proximity sensors provide
information to the slat flap control computer (SFCC) and the
operation of the flap drive system is inhibited.
An engineering investigation showed that, when a certain
combination of target/sensor serial number (s/n) is installed on a
flap interconnecting strut, a ``target FAR'' signal cannot be
detected when reaching the mechanical end stop of the
interconnecting strut.
This condition, if not corrected, could cause a flap down drive
disconnection to remain undetected, due to an already-failed
interconnecting strut sensor, potentially resulting in asymmetric
flap panel movement and consequent loss of control of the aeroplane.
To address this potential unsafe condition, Airbus issued
Service Bulletin (SB) A320-27-1206 and SB A320-57-1164, to provide
identification and replacement instructions for struts that have a
certain target/sensor s/n combination installed. Aeroplanes on which
modification (mod) 27956 had been accomplished in production were
identified as not affected by the unsafe condition. Consequently,
EASA issued [EASA] AD 2012-0012 [which corresponds to FAA AD 2014-
08-01] to require accomplishment of these inspections and corrective
actions.
Since that [EASA] AD was issued, Airbus has informed EASA about
a batch of aeroplanes that were delivered with pre-mod 27956 Part
Number (P/N) flap interconnecting strut(s) installed, but declared
to be in post-mod configuration in the Aircraft Inspection Report.
Airbus SB A320-57-1202 has been issued to provide instructions to
verify the interconnecting strut P/N, and to update aircraft
documentation.
In addition, to ensure that all pre-mod parts are checked and
corrected as required, SB A320-27-1206 was revised to include a
wider range of P/N of affected interconnecting struts.
For the reasons described above, this [EASA] AD retains the
requirements of EASA
[[Page 56860]]
AD 2012-0012, which is superseded, expands the Applicability [adds
affected part numbers], changes the compliance time and requires an
additional inspection for aeroplanes that have already been
inspected.

0476.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the NPRM and
the FAA's response to each comment. United Airlines and the Air Line
Pilots Association, International supported the NPRM.
Request To Add Additional Identification Steps
Delta Airlines (DAL) requested that additional identification steps
be required in the NPRM to ensure that the affected parts are correctly
identified. DAL stated that figure 1 to paragraphs (g) and (h) of the
proposed AD contains part numbers for affected interconnecting struts.
DAL commented that a review of its records from inspections conducted
during compliance with AD 2014-08-01 determined that other part numbers
were possible. DAL stated that it has had at least one instance of a
part with the part number D5757032200000A.
DAL stated that figure 2 to paragraphs (i)(2), (k), and (l) of the
proposed AD adds the provision that additional alphanumeric characters
may exist. DAL commented that while the NPRM removes some of the
ambiguity that existed in AD 2014-08-01, a review of Airbus's Aircraft
Illustrated Parts Catalog (AIPC) does not show any parts with a
``letter'' suffix. DAL provided a photo that showed that the part
number appears to ``wrap'' (to the next line) on the part. DAL stated
that this ``wrapping'' condition has led to confusion in identifying
the parts.
DAL stated that per the Airbus AIPC Front Matter, the 13th, 14th,
and 15th characters are controlled in specific ways. DAL also stated
that the 13th and 14th characters are expected to be ``00'' and are
used to fill out 12-digit base numbers on the part installed during
production. DAL stated that the 15th character is a paint code
designator and found the use of a paint code designator unusual on a
part that is not viewable or expected to be painted to match an air
carrier paint scheme. DAL commented that it believes the AD should be
updated to show 00A, 00B, or the list of true possibilities, and the
XXX allowance creates a significant number of possible part numbers
that DAL must identify as prohibited.
We agree to clarify the requirement to identify affected parts.
Regarding the characters in the part number, identifying the last three
characters are not required to identify a discrepant part; only the
first twelve base numbers are required. Therefore, we do not agree to
revise this AD to include a complete list of all possible combinations
of these characters.
We acknowledge the commenter's concern about the ``wrapping''
condition for part identification. However, in the photo provided by
the commenter only the last three characters are ``wrapped.'' As stated
previously, the last three characters are not required to identify a
discrepant part.
Formatting Change to a Figure
Figure 3 to paragraph (k)(1) of this AD has been reformatted to
clarify affected manufacturer serial numbers.
Records Review
We have determined that a review of maintenance records is
acceptable for complying with the actions specified in paragraphs
(i)(1) and (i)(2) of this AD, provided the part number of the installed
interconnecting struts and the part number and the serial number of the
associated target and proximity sensor can be conclusively determined
from that review. We have revised paragraph (i) of this AD accordingly.
Conclusion
We reviewed the available data, including the comments received,
and determined that air safety and the public interest require adopting
this AD as proposed except for minor editorial changes. We have
determined that these minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
<bullet> 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.
Related Service Information Under 1 CFR Part 51
Airbus has issued Service Bulletin A320-27-1206, Revision 02, dated
November 2, 2015. The service information describes procedures for an
inspection to determine the part number of the installed
interconnecting struts and the part number and serial number of the
associated target and proximity sensors, and procedures for replacement
and re-identification of the interconnecting struts. 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 1,032 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection and replacement 8 work-hours x $85 per hour $0 $680 $701,760
(retained actions from AD 2014-08- = $680.
01).
Inspection and replacement (new 15 work-hours x $85 per 0 1,275 1,315,800
action). hour = $1,275.
----------------------------------------------------------------------------------------------------------------
We have received no definitive data that would enable us to provide
cost estimates for the on-condition actions specified in 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
[[Page 56861]]
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.

2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD)
2014-08-01, Amendment 39-17825 (79 FR 23900, April 29, 2014), and
adding the following new AD:
2017-24-07 Airbus: Amendment 39-19111; Docket No. FAA-2017-0476;
Product Identifier 2016-NM-110-AD.
(a) Effective Date
This AD is effective January 5, 2018.
(b) Affected ADs
This AD replaces AD 2014-08-01, Amendment 39-17825 (79 FR 23900,
April 29, 2014) (``AD 2014-08-01'').
(c) Applicability
This AD applies to Airbus Model A318-111, -112, -121, and -122
airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -
133 airplanes; Model A320-211, -212, -214, -231, -232, and -233

Air Transport Association (ATA) of America Code 27, Flight
controls.
(e) Reason
This AD was prompted by an investigation that showed that when a
certain combination of target/proximity sensor serial numbers is
installed on a flap interconnecting strut, a ``target FAR'' signal
cannot be detected when reaching the mechanical end stop of the
interconnecting strut. We are issuing this AD to prevent an
undetected flap down drive disconnection due to an already-failed
interconnecting strut sensor, which could result in asymmetric flap
panel movement and consequent loss of control of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Retained Inspection To Determine the Part Number of the
Interconnecting Struts, With Revised Service Information
This paragraph restates the requirements of paragraph (g) of AD
2014-08-01, with revised service information. Within 8,000 flight
hours after March 26, 2014 (the effective date of AD 2014-03-08,
Amendment 39-17745 (79 FR 9398, February 19, 2014) (``AD 2014-03-
08'')), inspect to determine the part number of the interconnecting
struts installed on both the left-hand (LH) and right-hand (RH)
wings of the airplane, in accordance with the Accomplishment
Instructions of Airbus Service Bulletin A320-27-1206, Revision 01,
dated October 10, 2011; or Airbus Service Bulletin A320-27-1206,
Revision 02, dated November 2, 2015. A review of the airplane
maintenance records is acceptable for determining the part number of
the installed interconnecting struts, in lieu of the inspection, if
the part number of the installed interconnecting struts, and the
part number and the serial number of the associated target and
proximity sensor, can be conclusively determined from that review.
Accomplishment of the requirements of paragraph (i) of this AD
terminates the requirements of this paragraph.
(1) Airplanes on which Airbus Modification 27956 has been
embodied in production, and on which no interconnecting strut has
been replaced with a strut having a part number specified in figure
1 to paragraphs (g) and (h) of this AD since the airplane's first
flight: No further work is required by paragraph (g) of this AD.
(2) If, during the inspection required by paragraph (g) of this
AD, any interconnecting strut is installed with a part number
specified in figure 1 to paragraphs (g) and (h) of this AD: Within
8,000 flight hours after March 26, 2014 (the effective date of AD
2014-03-08), determine the part number and the serial number of the
associated target and proximity sensor.
(i) For airplanes having conditions specified in paragraphs
(g)(2)(i)(A), (g)(2)(i)(B), (g)(2)(i)(C), and (g)(2)(i)(D) of this

(h) Retained Parts Installation Prohibition, With No Changes
This paragraph restates the requirements of paragraph (h) of AD
2014-08-01, with no changes. As of March 26, 2014 (the effective
date of AD 2014-03-08), no person may install an interconnecting
strut with a part number specified in figure 1 to paragraphs (g) and
(h) of this AD, on any airplane, except for parts identified in
paragraph (g)(2)(ii) of this AD, provided that the actions in
paragraph (g)(2)(ii) are done. As of the effective date of this AD,
comply with the requirements of paragraph (l) of this AD in lieu of
the requirements of this paragraph.
(i) New Requirements of This AD: Inspection To Determine the Part
Number of the Interconnecting Struts and the Part Number and Serial
Number of the Associated Target and Proximity Sensor
Within 24 months after the effective date of this AD, accomplish
the actions specified in paragraphs (i)(1) and (i)(2) of this AD, in
accordance with the Accomplishment Instructions of Airbus Service
Bulletin A320-27-1206, Revision 02, dated November 2, 2015.
Accomplishment of the actions specified in this paragraph terminates
the requirements of paragraph (g) of this AD. In lieu of doing the
actions specified in paragraphs (i)(1) and (i)(2) of this AD, a
review of the airplane maintenance records is acceptable for
determining the part number of the installed interconnecting struts
and the part number and the serial number of the associated target
and proximity sensor, if the part number and serial numbers can be
conclusively determined from that review.
(1) Inspect to determine the part number of the interconnecting
struts installed on both the LH and RH wings on the airplane.
(2) If an interconnecting strut is installed with a part number
specified in figure 2 to paragraphs (i)(2), (k), and (l) of this AD,
identify the part number and the serial number of the associated
target and proximity sensor; and for the target and proximity sensor
part number and serial number combination specified in paragraph (j)
of this AD, within the compliance times specified in paragraph (j)
of this AD, do the actions specified in paragraph (j) of this AD for
that interconnecting strut.
[[Page 56863]]
[GRAPHIC] [TIFF OMITTED] TR01DE17.001
(j) New Requirements of This AD: Replacement or Re-Identification
