ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for all SUMMARY: PO 00000 Frm 00022 Fmt 4702 Sfmt 4702 20839 Airbus Model A330–200 Freighter, A330–200 and –300, and A340–200, –300, –500, and –600 series airplanes. This proposed AD was prompted by reassessment of an unsafe condition related to MZ-type spoiler servocontrols (SSCs) that did not remain locked in the retracted position (hydraulic locking function) after manual depressurization of the corresponding hydraulic circuit. This reassessment resulted in the determination that performing repetitive operational tests of all SSC types is necessary. This proposed AD would require repetitive operational tests of the hydraulic locking function on each SSC installed on the blue or yellow hydraulic circuits, and replacing any affected SSC with a serviceable SSC. We are proposing this AD to detect and correct loss of the hydraulic locking function during take-off, which, in combination with one inoperative engine, could result in reduced controllability of the airplane.

The MCAI states: During post-flight maintenance checks accomplished on an A330 and on an A340 airplane, it was identified that seven spoiler servo-controls MZ series had lost their hydraulic locking function. The results of the subsequent technical investigation accomplished in-shop by the part supplier confirmed the system failure was due to a sheared seal on the blocking valve, ensuring the blocking function of the spoiler. It is suspected that the seal damage may have occurred during accomplishment of a modification to fit a new design of maintenance cover on wing, required by EASA AD 2008–0160 [(https:// ad.easa.europa.eu/blob/easa_ad_2008_ 0160.pdf/AD_2008-0160)], [which VerDate Mar<15>2010 16:59 Apr 11, 2014 Jkt 232001 corresponds to FAA AD 2009–18–20, Amendment 39–16017 (74 FR 46313, September 9, 2009)]. This condition, if not detected and corrected, in combination with one engine inoperative at take-off, could result in reduced control of the aeroplane. Prompted by these findings, Airbus issued All Operators Telex (AOT) A330–27A3185 and AOT A340–27A4181 to request a onetime operational test of the Hydraulic Locking Function for aeroplanes on which MZ type Spoiler Servo Control (SSC) Part Number (P/N) MZ4339390–12 or P/N MZ4306000–12 are fitted, and EASA issued AD 2012–0009 https://ad.easa.europa.eu/ blob/easa_ad_2012_0009.pdf/AD_2012-0009 [which corresponds to FAA AD 2012–25–10, Amendment 39–17291 (77 FR 76228, December 27, 2012)] to require accomplishment of this test. Since that [EASA] AD was issued, Airbus re-assessed the situation and determined that it is necessary to introduce repetitive inspections [operational tests] of the SSC, irrespective of SSC type. Airbus issued three SBs for those repetitive inspections [operational tests] on all A330, A340, and A340–500/600 aeroplanes. For the reason described above, this [EASA] AD requires repetitive operational tests of the hydraulic locking function of the SSC installed on the Blue and Yellow hydraulic circuits, irrespective of the SSC type, and, depending on test results, replacement of the SSC. This [EASA] AD has been republished to correct the date of publication. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating it in Docket No. FAA– 2014–0228. Relevant Service Information Airbus has issued the following service information. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. • Airbus Mandatory Service Bulletin A330–27–3195, dated December 7, 2012. • Airbus Mandatory Service Bulletin A340–27–4188, dated December 7, 2012. • Airbus Mandatory Service Bulletin A340–27–5059, dated April 10, 2013. FAA’s Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe PO 00000 Frm 00023 Fmt 4702 Sfmt 4702 condition exists and is likely to exist or develop on other products of the same type design. Costs of Compliance We estimate that this proposed AD affects about 77 airplanes of U.S. registry. We also estimate that it would take about 6 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $39,270, or $510 per product. We estimate that it would take about 3 work-hours per product to do any necessary SSC replacement that would be required based on the results of the proposed operational test. Required parts would cost about $35,000 per SSC. We have no way of determining the number of aircraft that might need these replacements. 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 proposed 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation: 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); E:\FR\FM\14APP1.SGM 14APP1 Federal Register / Vol. 79, No. 71 / Monday, April 14, 2014 / Proposed Rules 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.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Airbus Model A330-200 Freighter, A330-200 and -300, and A340-200, -300, 
-500, and -600 series airplanes. This proposed AD was prompted by 
reassessment of an unsafe condition related to MZ-type spoiler servo-
controls (SSCs) that did not remain locked in the retracted position 
(hydraulic locking function) after manual depressurization of the 
corresponding hydraulic circuit. This reassessment resulted in the 
determination that performing repetitive operational tests of all SSC 
types is necessary. This proposed AD would require repetitive 
operational tests of the hydraulic locking function on each SSC 
installed on the blue or yellow hydraulic circuits, and replacing any 
affected SSC with a serviceable SSC. We are proposing this AD to detect 
and correct loss of the hydraulic locking function during take-off, 
which, in combination with one inoperative engine, could result in 
reduced controllability of the airplane.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2013-0251 dated October 15, 2013; Correction 
dated October 16, 2013 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for the specified products. The MCAI states:

    During post-flight maintenance checks accomplished on an A330 
and on an A340 airplane, it was identified that seven spoiler servo-
controls MZ series had lost their hydraulic locking function. The 
results of the subsequent technical investigation accomplished in-
shop by the part supplier confirmed the system failure was due to a 
sheared seal on the blocking valve, ensuring the blocking function 
of the spoiler. It is suspected that the seal damage may have 
occurred during accomplishment of a modification to fit a new design 
of maintenance cover on wing, required by EASA AD 2008-0160 [(https://ad.easa.europa.eu/blob/easa_ad_2008_0160.pdf/AD_2008-0160)], 
[which corresponds to FAA AD 2009-18-20, Amendment 39-16017 (74 FR 
46313, September 9, 2009)].
    This condition, if not detected and corrected, in combination 
with one engine inoperative at take-off, could result in reduced 
control of the aeroplane.
    Prompted by these findings, Airbus issued All Operators Telex 
(AOT) A330-27A3185 and AOT A340-27A4181 to request a one-time 
operational test of the Hydraulic Locking Function for aeroplanes on 
which MZ type Spoiler Servo Control (SSC) Part Number (P/N) 
MZ4339390-12 or P/N MZ4306000-12 are fitted, and EASA issued AD 
2012-0009 https://ad.easa.europa.eu/blob/easa_ad_2012_0009.pdf/AD_2012-0009 [which corresponds to FAA AD 2012-25-10, Amendment 39-
17291 (77 FR 76228, December 27, 2012)] to require accomplishment of 
this test.
    Since that [EASA] AD was issued, Airbus re-assessed the 
situation and determined that it is necessary to introduce 
repetitive inspections [operational tests] of the SSC, irrespective 
of SSC type. Airbus issued three SBs for those repetitive 
inspections [operational tests] on all A330, A340, and A340-500/600 
aeroplanes.
    For the reason described above, this [EASA] AD requires 
repetitive operational tests of the hydraulic locking function of 
the SSC installed on the Blue and Yellow hydraulic circuits, 
irrespective of the SSC type, and, depending on test results, 
replacement of the SSC.
    This [EASA] AD has been republished to correct the date of 
publication.

Relevant Service Information

    Airbus has issued the following service information. The actions 
described in this service information are intended to correct the 
unsafe condition identified in the MCAI.
     Airbus Mandatory Service Bulletin A330-27-3195, dated 
December 7, 2012.
     Airbus Mandatory Service Bulletin A340-27-4188, dated 
December 7, 2012.
     Airbus Mandatory Service Bulletin A340-27-5059, dated 
April 10, 2013.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Costs of Compliance

    We estimate that this proposed AD affects about 77 airplanes of 
U.S. registry.
    We also estimate that it would take about 6 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of the proposed AD on U.S. operators to be $39,270, or $510 
per product.
    We estimate that it would take about 3 work-hours per product to do 
any necessary SSC replacement that would be required based on the 
results of the proposed operational test. Required parts would cost 
about $35,000 per SSC. We have no way of determining the number of 
aircraft that might need these replacements.

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 proposed 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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);

[[Page 20841]]

    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.

reference, Safety.

The Proposed Amendment

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

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

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

Airbus: Docket No. FAA-2014-0228; Directorate Identifier 2013-NM-
216-AD.

(a) Comments Due Date

    We must receive comments by May 29, 2014.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus Model A330-201, -202, -203, -223, -
223F, -243, -243F, -301, -302, 303, -321, -322, -323, -341, -342, 
and -343 airplanes; Model A340-211, -212, -213, -311, -312, and -313 
airplanes; and Model A340-541 and -642 airplanes, certificated in 
any category; all manufacturer serial numbers (MSN).

(d) Subject

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

(e) Reason

    This AD was prompted by reassessment of an unsafe condition 
related to MZ-type spoiler servo-controls (SSCs) that did not remain 
locked in the retracted position (hydraulic locking function) after 
manual depressurization of the corresponding hydraulic circuit. This 
reassessment resulted in the determination that performing 
repetitive operational tests of all SSC types is necessary. We are 
issuing this AD to detect and correct loss of the hydraulic locking 
function during take-off, which, in combination with one inoperative 
engine, could result in reduced controllability of the airplane.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

(g) Repetitive Operational Tests

    (1) At the time specified in paragraph (g)(2) of this AD: 
Accomplish an operational test of the hydraulic locking function on 
each SSC (any type), when fitted on the Blue or Yellow hydraulic 
circuits, in accordance with the Accomplishment Instructions of the 
applicable service information identified in paragraph (g)(1)(i), 
(g)(1)(ii) or (g)(1)(iii) of this AD. Repeat the operational test 
thereafter at intervals not to exceed 48 months.
