Airworthiness Directives; Airbus SAS Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus SAS Model A330-200, -200 Freighter, and -300 series airplanes, 
and Model A340-200, -300, -500, and -600 series airplanes. This AD was 
prompted by a report that certain sensor struts, in the case of down 
drive element disconnection, would be unable to provide failure 
detection information for flap movements. This AD requires repetitive 
inspections of certain drive station elements and sensor struts; an 
inspection of certain other drive station elements if necessary; and 
corrective actions if necessary. We are issuing this AD to address the 
unsafe condition on these products.

DATES: This AD is effective April 3, 2019.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of April 3, 
2019.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to all Airbus SAS Model A330-
200, -200 Freighter, and -300 series airplanes, and Model A340-200, -
300, -500, and -600 series airplanes. The NPRM published in the Federal 
Register on November 5, 2018 (83 FR 55303). The NPRM was prompted by a 
report that certain sensor struts, in the case of down drive element 
disconnection, would be unable to provide failure detection 
information. The NPRM proposed to require repetitive inspections of 
certain drive station elements and sensor struts; an inspection of 
certain other drive station elements if necessary; and corrective 
actions if necessary.
    We are issuing this AD to address abnormal flap movement due to 
mechanical drive station element disconnection at flap track station 4 
or station 5 which could lead to undetected down drive shaft 
disconnection. Such a condition could result in complete flap 
disconnection in the case of additional failure on the remaining flap 
drive station, and could ultimately result in loss of control of the 
airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2018-0151, dated July 16, 2018 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for all Airbus SAS Model A330-200 Freighter series, 
Model A330-200 series, Model A330-300 series, Model A340-200 series, 
Model A340-300 series, Model A340-500 series, and Model A340-600 series 
airplanes. The MCAI states:

    Design features of the track station 4 sensor struts, 
respectively installed on the right hand (RH) and left hand (LH) 
wings of an aeroplane, ensure detection of any abnormal flap 
movement in case of a mechanical DSE [drive station element] 
disconnection at the level of the flap track station 4 or flap track 
station 5. Evidence was collected revealing that the track station 4 
sensor strut, in case of a down drive element disconnection, would 
be unable to provide failure detection information.
    This condition, if not detected and corrected, in the case of an 
additional failure on the remaining flap drive station, could lead 
to a complete flap disconnection, possibly resulting in loss of 
control of the aeroplane.
    To address this potential unsafe condition, Airbus published the 
applicable SB [Airbus Service Bulletin A330-27-3226, dated April 5, 
2018; Airbus Service Bulletin A340-27-4206, dated April 3, 2018; or 
Airbus Service Bulletin A340-27-5071, dated April 3, 2018; as 
applicable] to provide inspection instructions of the track station 
4 and track station 5 DSE and sensor struts of the LH and RH wings.
    For the reasons described above, this [EASA] AD requires 
repetitive [detailed] inspections of the LH and RH track station 4 
[DSE, repetitive general visual inspections of the LH and RH track 
station 4 sensor struts,] and [for certain airplanes, a one-time 
detailed inspection of the LH or RH, as applicable] track station 5 
DSE * * * and, depending on findings, accomplishment of applicable 
corrective action(s).

    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-2018-
0904.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We received no comments on the NPRM or on the 
determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this final rule 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 addressing the unsafe condition; and
    <bullet> 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.
    <bullet> Airbus Service Bulletin A330-27-3226, dated April 5, 2018.
    <bullet> Airbus Service Bulletin A340-27-4206, dated April 3, 2018.
    <bullet> Airbus Service Bulletin A340-27-5071, dated April 3, 2018.
    This service information describes procedures for repetitive 
detailed inspections of the LH and RH track station 4 drive station 
elements; repetitive general visual inspections of the LH and RH track 
station 4 sensor struts; a detailed inspection of the track station 5 
drive station elements if any discrepancy is found during a general 
visual inspection; and corrective actions (i.e., replacement of 
affected parts). These documents are distinct since they apply to 
different models. 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 105 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                     Estimated Costs for Required Actions *
----------------------------------------------------------------------------------------------------------------
              Labor cost                   Parts cost        Cost per product         Cost on  U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 7 work-hours x $85 per hour =                 $0   Up to $595..............  Up to $62,475.
 $595.
----------------------------------------------------------------------------------------------------------------
* Table does not include estimated costs for reporting.

    We estimate that it would take about 1 work-hour per product to 
comply with the reporting requirement in this AD. The average labor 
rate is $85 per hour. Based on these figures, we estimate the cost of 
reporting the inspection results on U.S. operators to be $8,925, or $85 
per product.
    We have received no definitive data that would enable us to provide 
cost

[[Page 6319]]

estimates for the on-condition actions specified in this AD.
    According to the manufacturer, some or all of the costs of this 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.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800 Independence Ave. SW, Washington, DC 20591, ATTN: Information 
Collection Clearance Officer, AES-200.

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 and 
associated appliances to the Director of the System Oversight Division.

Regulatory Findings

    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.

    (7) Model A340-642 airplanes.

(d) Subject

    Air Transport Association (ATA) of America Code 27, Flight 
controls.

(e) Reason

    This AD was prompted by a report that the right-hand (RH) and 
left-hand (LH) track station 4 sensor struts, in the case of down 
drive element disconnection, would be unable to provide failure 
detection information for flap movements. We are issuing this AD to 
address abnormal flap movement due to mechanical drive station 
element disconnection at flap track station 4 or station 5 which 
could lead to undetected down drive shaft disconnection. Such a 
condition could result in complete flap disconnection in the case of 
additional failure on the remaining flap drive station, and could 
ultimately result in loss of control of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Definitions

    For the purpose of this AD, the drive station elements are 
defined as the down drive, down drive shaft, geared rotary actuator 
(gearbox), geared rotary actuator (output lever and fork end), and 
drive strut.

(h) Detailed and General Visual Inspections

    (1) At the applicable times specified in paragraphs (h)(1)(i) 
and (h)(1)(ii) of this AD, and thereafter not to exceed the 
applicable intervals specified in table 1 to paragraph (h)(1) of 
this AD, do a detailed inspection of the LH and RH track station 4 
drive station elements for corrosion or ruptured, loose, or missing 
components (including any attached bolts and nuts that are loose, 
broken, or missing) and a general visual inspection of the LH and RH 
track station 4 sensor struts for corrosion or ruptured, loose, or 
missing components (including any attached bolts that are loose, 
broken, or missing), in accordance with the Accomplishment 
Instructions of Airbus Service Bulletin A330-27-3226, dated April 5, 
2018; Airbus Service Bulletin A340-27-4206, dated April 3, 2018; or
