ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for all SUMMARY: VerDate Sep<11>2014 22:59 May 19, 2016 Jkt 238001 Airbus Model A330–200 Freighter, A330–200, A330–300, A340–200, A340– 300, A340–500, and A340–600 series airplanes. This AD was prompted by the results of endurance qualification tests on the trimmable horizontal stabilizer actuator (THSA), which revealed a partial loss of the no-back brake (NBB) efficiency in specific load conditions. This AD requires inspecting certain THSAs to determine the number of total flight cycles the THSA has accumulated, and replacing the THSA if necessary. We are issuing this AD to detect and correct premature wear of the carbon friction disks on the NBB of the THSA. Such a condition could lead to reduced braking efficiency in certain load conditions and, in conjunction with the inability of the power gear train to keep the ball screw in its last commanded position, could result in uncommanded movements of the trimmable horizontal PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 stabilizer (THS) and loss of control of the airplane. This AD is effective June 24, 2016. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of June 24, 2016.

SUPPLEMENTARY INFORMATION: mstockstill on DSK5VPTVN1PROD with RULES Discussion We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Airbus Model A330–200 Freighter, A330–200, A330– 300, A340–200, A340–300, A340–500, and A340–600 series airplanes. The SNPRM published in the Federal Register on December 23, 2015 (80 FR 79738) (‘‘the SNPRM’’). We preceded the SNPRM with a notice of proposed rulemaking (NPRM) that published in the Federal Register on February 3, 2014 (79 FR 6104) (‘‘the NPRM’’). The NPRM proposed to require inspecting certain THSAs to determine the number of total flight cycles the THSA has accumulated, and replacing the THSA if necessary. The NPRM was prompted by the results of endurance qualification tests on the THSA, which revealed a partial loss of the NBB efficiency in specific load conditions. The SNPRM proposed to revise the NPRM by adding airplanes to the proposed applicability, reducing the proposed compliance times for replacing affected TSHAs, and revising the definition of a serviceable THSA. We are issuing this AD to detect and correct premature wear of the carbon friction disks on the NBB of the THSA. Such a condition could lead to reduced braking efficiency in certain load conditions and, in conjunction with the inability of the power gear train VerDate Sep<11>2014 22:59 May 19, 2016 Jkt 238001 to keep the ball screw in its last commanded position, could result in uncommanded movements of the THS and 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 Airworthiness Directive 2014–0257R1, dated May 29, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition on all Airbus Model A330–200, A330–200 Freighter, A330– 300, A340–200, and A340–300 series airplanes; and Model A340–500 and A340–600 series airplanes. The MCAI states: During endurance qualification tests on Trimmable Horizontal Stabilizer Actuator (THSA) of another Airbus aeroplane type, a partial loss of the no-back brake (NBB) efficiency was experienced. Due to THSA design similarity on the A330/A340 fleet, a similar partial loss of the NBB efficiency was identified on THSA Part Number (P/N) 47147 as installed on A330–300 and A340–200/– 300 aeroplanes, on THSA P/N 47172 as installed on A330–200/–300 and A340–200/ –300 aeroplanes, and on THSA P/N 47175 as installed on A340–500/600 aeroplanes. Investigation results concluded that this partial loss of braking efficiency in some specific aerodynamic load conditions was due to polishing and auto-contamination of the NBB carbon friction disks. This condition, if not detected and corrected and in conjunction with the power gear train not able to keep the ball screw in its last commanded position, could lead to uncommanded movements of the THS, possibly resulting in loss of control of the aeroplane. To address this potential unsafe condition, EASA issued AD 2013–0144 [http:// ad.easa.europa.eu/blob/easa_ad_2013_ 0144.zip/AD_2013-0144R1_2] to require replacement of each THSA that has exceeded 16,000 flight cycles (FC) in service, to be sent in shop for NBB carbon disk replacement. Since that AD was issued, a need for clarification has been demonstrated, regarding the identification of the THSA ‘affected’ by this requirement. For this reason, EASA AD 2013–0144 [http://ad.easa.europa.eu/blob/easa_ad_ 2013_0144.zip/AD_2013-0144R1_2] was revised, confirming that this AD only affected those THSA identified by Part Number (P/N) in Airbus Alert Operator Transmission (AOT) A27L005–13. In addition, a note was added to make clear that the life limits as specified in the current revision of ALS Part 4 are still relevant for the affected THSA, as applicable to aeroplane model and THSA P/N. Since EASA AD 2013–0144R1 [http:// ad.easa.europa.eu/ad/2013-0144R1] was issued, further assessment of the ageing/ endurance issue has resulted in the conclusion that there is a need to replace the NBB installed on the THSA. Consequently, EASA issued AD 2014–0257 [http://ad.easa.europa.eu/blob/EASA_AD_ 2014_0257_R1.pdf/AD_2014-0257R1_1] PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 31845 which retained the requirements of EASA AD 2013–0144R1, which was superseded, and required removal from service of affected THSA. THSA should be sent in shop for NBB carbon disk replacement. This [EASA] AD affected additional THSA P/Ns when compared to EASA AD 2013–0144R1 and Airbus AOT A27L005–13. Since that [EASA] AD was issued, it was determined that it is necessary to consider that the THSA removal for NBB disks replacement could also be calculated since last NBB disk replacement which was done in-shop. This AD also adds Model A340–541 and A340–642 airplanes to the applicability. 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–2014– 0006. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the SNPRM 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 AD as proposed except for minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the SNPRM for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the SNPRM. Related Service Information Under 1 CFR Part 51 Airbus has issued the following service information, all dated July 15, 2014. • Service Bulletin A330–27–3199 (for Model A330 series airplanes); • Service Bulletin A340–27–4190 (for Model A340–200 and –300 series airplanes); and • Service Bulletin A340–27–5062 (for Model A340–500 and –600 series airplanes). The service information describes procedures for inspecting the THSA to determine the part number and replacing THSAs having certain part numbers with a new or serviceable part. 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 94 airplanes of U.S. registry. E:\FR\FM\20MYR1.SGM 20MYR1 31846 Federal Register / Vol. 81, No. 98 / Friday, May 20, 2016 / Rules and Regulations We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Inspection ........................................................ 3 work-hours × $85 per hour = $255 ............. $0 $255 $23,970 We estimate the following costs to do any necessary replacements that will be required based on the results of the required inspection. We have no way of determining the number of airplanes that might need these replacements: ON-CONDITION COSTS Action Labor cost Parts cost Cost per product Replacement ................................................................. 23 work-hour × $85 per hour = $1,955 ........................ $722,556 $724,511 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. mstockstill on DSK5VPTVN1PROD with RULES 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 VerDate Sep<11>2014 22:59 May 19, 2016 Jkt 238001 under the criteria of the Regulatory Flexibility Act. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus Model A330-200 Freighter, A330-200, A330-300, A340-200, A340-
300, A340-500, and A340-600 series airplanes. This AD was prompted by 
the results of endurance qualification tests on the trimmable 
horizontal stabilizer actuator (THSA), which revealed a partial loss of 
the no-back brake (NBB) efficiency in specific load conditions. This AD 
requires inspecting certain THSAs to determine the number of total 
flight cycles the THSA has accumulated, and replacing the THSA if 
necessary. We are issuing this AD to detect and correct premature wear 
of the carbon friction disks on the NBB of the THSA. Such a condition 
could lead to reduced braking efficiency in certain load conditions 
and, in conjunction with the inability of the power gear train to keep 
the ball screw in its last commanded position, could result in 
uncommanded movements of the trimmable horizontal stabilizer (THS) and 
loss of control of the airplane.

DATES: This AD is effective June 24, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of June 24, 
2016.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 by adding an AD that would apply to all Airbus 
Model A330-200 Freighter, A330-200, A330-300, A340-200, A340-300, A340-
500, and A340-600 series airplanes. The SNPRM published in the Federal 
Register on December 23, 2015 (80 FR 79738) (``the SNPRM''). We 
preceded the SNPRM with a notice of proposed rulemaking (NPRM) that 
published in the Federal Register on February 3, 2014 (79 FR 6104) 
(``the NPRM''). The NPRM proposed to require inspecting certain THSAs 
to determine the number of total flight cycles the THSA has 
accumulated, and replacing the THSA if necessary. The NPRM was prompted 
by the results of endurance qualification tests on the THSA, which 
revealed a partial loss of the NBB efficiency in specific load 
conditions. The SNPRM proposed to revise the NPRM by adding airplanes 
to the proposed applicability, reducing the proposed compliance times 
for replacing affected TSHAs, and revising the definition of a 
serviceable THSA. We are issuing this AD to detect and correct 
premature wear of the carbon friction disks on the NBB of the THSA. 
Such a condition could lead to reduced braking efficiency in certain 
load conditions and, in conjunction with the inability of the power 
gear train to keep the ball screw in its last commanded position, could 
result in uncommanded movements of the THS and 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 
Airworthiness Directive 2014-0257R1, dated May 29, 2015 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition on all Airbus Model A330-
200, A330-200 Freighter, A330-300, A340-200, and A340-300 series 
airplanes; and Model A340-500 and A340-600 series airplanes. The MCAI 
states:

    During endurance qualification tests on Trimmable Horizontal 
Stabilizer Actuator (THSA) of another Airbus aeroplane type, a 
partial loss of the no-back brake (NBB) efficiency was experienced. 
Due to THSA design similarity on the A330/A340 fleet, a similar 
partial loss of the NBB efficiency was identified on THSA Part 
Number (P/N) 47147 as installed on A330-300 and A340-200/-300 
aeroplanes, on THSA P/N 47172 as installed on A330-200/-300 and 
A340-200/-300 aeroplanes, and on THSA P/N 47175 as installed on 
A340-500/600 aeroplanes.
    Investigation results concluded that this partial loss of 
braking efficiency in some specific aerodynamic load conditions was 
due to polishing and auto-contamination of the NBB carbon friction 
disks.
    This condition, if not detected and corrected and in conjunction 
with the power gear train not able to keep the ball screw in its 
last commanded position, could lead to uncommanded movements of the 
THS, possibly resulting in loss of control of the aeroplane.
    To address this potential unsafe condition, EASA issued AD 2013-
0144 [http://ad.easa.europa.eu/blob/easa_ad_2013_0144.zip/AD_2013-0144R1_2] to require replacement of each THSA that has exceeded 
16,000 flight cycles (FC) in service, to be sent in shop for NBB 
carbon disk replacement.
    Since that AD was issued, a need for clarification has been 
demonstrated, regarding the identification of the THSA `affected' by 
this requirement.
    For this reason, EASA AD 2013-0144 [http://ad.easa.europa.eu/blob/easa_ad_2013_0144.zip/AD_2013-0144R1_2] was revised, confirming 
that this AD only affected those THSA identified by Part Number (P/
N) in Airbus Alert Operator Transmission (AOT) A27L005-13. In 
addition, a note was added to make clear that the life limits as 
specified in the current revision of ALS Part 4 are still relevant 
for the affected THSA, as applicable to aeroplane model and THSA P/
N.
    Since EASA AD 2013-0144R1 [http://ad.easa.europa.eu/ad/2013-0144R1] was issued, further assessment of the ageing/endurance issue 
has resulted in the conclusion that there is a need to replace the 
NBB installed on the THSA.
    Consequently, EASA issued AD 2014-0257 [http://ad.easa.europa.eu/blob/EASA_AD_2014_0257_R1.pdf/AD_2014-0257R1_1] 
which retained the requirements of EASA AD 2013-0144R1, which was 
superseded, and required removal from service of affected THSA. THSA 
should be sent in shop for NBB carbon disk replacement. This [EASA] 
AD affected additional THSA P/Ns when compared to EASA AD 2013-
0144R1 and Airbus AOT A27L005-13.
    Since that [EASA] AD was issued, it was determined that it is 
necessary to consider that the THSA removal for NBB disks 
replacement could also be calculated since last NBB disk replacement 
which was done in-shop.

This AD also adds Model A340-541 and A340-642 airplanes to the 
applicability. 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-2014-0006.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the SNPRM 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 AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
SNPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM.

Related Service Information Under 1 CFR Part 51

    Airbus has issued the following service information, all dated July 
15, 2014.
     Service Bulletin A330-27-3199 (for Model A330 series 
airplanes);
     Service Bulletin A340-27-4190 (for Model A340-200 and -300 
series airplanes); and
     Service Bulletin A340-27-5062 (for Model A340-500 and -600 
series airplanes).
    The service information describes procedures for inspecting the 
THSA to determine the part number and replacing THSAs having certain 
part numbers with a new or serviceable part. 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 94 airplanes of U.S. registry.

[[Page 31846]]

    We estimate the following costs to comply with 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.

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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2016-10-08 Airbus: Amendment 39-18519. Docket No. FAA-2014-0006; 
Directorate Identifier 2013-NM-147-AD.

(a) Effective Date

    This AD is effective June 24, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to the Airbus airplanes, certificated in any 
category, identified in paragraphs (c)(1) through (c)(7) of this AD, 
all manufacturer serial numbers.
    (1) Model A330-201, -202, -203, -223, and -243 airplanes.
    (2) Model A330-223F and -243F airplanes.
    (3) Model A330-301, -302, -303, -321, -322, -323, -341, -342, 
and -343 airplanes.
    (4) Model A340-211, -212, and -213 airplanes.

    (7) Model A340-642 airplanes.

(d) Subject

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

(e) Reason

    This AD was prompted by the results of endurance qualification 
tests on the trimmable horizontal stabilizer actuator (THSA), which 
revealed a partial loss of the no-back brake (NBB) efficiency in 
specific load conditions. We are issuing this AD to detect and 
correct premature wear of the carbon friction disks on the NBB of 
the THSA. Such a condition could lead to reduced braking efficiency 
in certain load conditions and, in conjunction with the inability of 
the power gear train to keep the ball screw in its last commanded 
position, could result in uncommanded movements of the trimmable 
horizontal stabilizer and loss of control of the airplane.

(f) Compliance

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

(g) Inspection To Determine THSA Part Number and Accumulated Total 
Flight Cycles

    Within 90 days after the effective date of this AD: Inspect the 
THSA to determine if it has a part number that is specified in 
paragraph (g)(1) or (g)(2) of this AD, and to determine the total 
number of flight cycles accumulated since the THSA's first 
installation on an airplane, or since the most recent NBB 
replacement. A review of airplane delivery or maintenance records is 
acceptable in lieu of this inspection if the part number of the THSA 
can be conclusively determined from that review.
    (1) For Model A330-200 Freighter, A330-200, A330-300, A340-200 
and A340-300 series airplanes: Part number (P/N) 47147-500, 47147-
700, 47172-300, 47172-500, 47172-510, or 47172-520.
    (2) For Model A340-500 and -600 series airplanes: P/N 47175-200, 
47175-300, 47175-500, or 47175-520.

A330-300, A340-200, and A340-300 Series Airplanes

    For Airbus Model A330-200 Freighter, A330-200, A330-300, A340-
200, and A340-300 series airplanes having a THSA with a part number 
specified in paragraph (g)(1) of this AD: At the applicable time 
specified in paragraph (h)(1), (h)(2), or (h)(3) of this AD, replace 
each affected THSA with a serviceable THSA, in accordance with the 
Accomplishment Instructions of Airbus Service Bulletin A330-27-3199, 
dated July 15, 2014; or Airbus Service Bulletin A340-27-4190, dated 
July 15, 2014; as applicable.

    Note 1 to paragraphs (h), (i), and (j) of this AD:  The THSA 
life limits specified in Part 4--Aging System Maintenance of the 
Airbus A330 and A340 Airworthiness Limitations Sections are still
