ACTION: Final rule. sroberts on PROD1PC70 with RULES AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A330 airplanes and Model A340–200 and –300 series airplanes. This AD requires inspecting to determine the part number of certain S4- and MZ-type spoiler servo controls (SSCs). For certain other airplanes, this AD requires inspecting to determine the part number of all SSCs. This AD also requires replacing any affected SSC with a new SSC. This AD results from a new load duty cycle defined by the manufacturer. Additional fatigue tests and calculations done on this basis indicated that the spoiler valve manifold of the S4-type SSCs, and, on certain airplanes, the maintenance cover of the MZ-type SSCs, may crack during its service life due to pressure impulse fatigue. We are issuing this AD to prevent fatigue cracking of certain SSCs, which could result in hydraulic leakage and consequent loss of SSC function and loss of the associated hydraulic VerDate Aug<31>2005 15:48 Mar 06, 2007 Jkt 211001 system. These conditions could affect all three hydraulic systems, which could result in reduced controllability of the airplane. DATES: This AD becomes effective April 11, 2007. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of April 11, 2007. ADDRESSES: You may examine the AD docket on the Internet at http:// dms.dot.gov or in person at the Docket Management Facility, U.S. Department of Transportation, 400 Seventh Street SW., Nassif Building, Room PL–401, Washington, DC.

FOR FURTHER INFORMATION CONTACT: Tim Backman, Aerospace Engineer, International Branch, ANM–116, FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, Washington 98057–3356; telephone (425) 227–2797; fax (425) 227–1149. SUPPLEMENTARY INFORMATION: Examining the Docket You may examine the airworthiness directive (AD) docket on the Internet at http://dms.dot.gov or in person at the Docket Management Facility office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Management Facility office (telephone (800) 647–5227) is located on the plaza level of the Nassif Building at the street address stated in the ADDRESSES section. Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to certain Airbus Model A330 airplanes and Model A340–200 and –300 series airplanes. That NPRM was published in the Federal Register on December 28, 2006 (71 FR 78102). That PO 00000 Frm 00025 Fmt 4700 Sfmt 4700 Date NPRM proposed to require inspecting to determine the part number of certain S4- and MZ-type spoiler servo-controls (SSCs). For certain other airplanes, that NPRM proposed to require inspecting to determine the part number of all SSCs. That NPRM also proposed to require replacing any affected SSC with a new SSC. Comments We provided the public the opportunity to participate in the development of this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance This AD affects about 27 airplanes of U.S. registry. It takes about 1 work hour per airplane to accomplish the inspection to determine the part number, at an average labor rate of $80 per work hour. Based on these figures, the estimated cost of the inspection required by this AD for U.S. operators is $2,160, or $80 per airplane. 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 E:\FR\FM\07MRR1.SGM 07MRR1 10058 Federal Register / Vol. 72, No. 44 / Wednesday, March 7, 2007 / Rules and Regulations 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 have 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 DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and (3) 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. We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation.

Airworthiness Directives; Airbus Model A330 Airplanes and Model 
A340-200 and -300 Series Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Airbus Model A330 airplanes and Model A340-200 and -300 series 
airplanes. This AD requires inspecting to determine the part number of 
certain S4- and MZ-type spoiler servo controls (SSCs). For certain 
other airplanes, this AD requires inspecting to determine the part 
number of all SSCs. This AD also requires replacing any affected SSC 
with a new SSC. This AD results from a new load duty cycle defined by 
the manufacturer. Additional fatigue tests and calculations done on 
this basis indicated that the spoiler valve manifold of the S4-type 
SSCs, and, on certain airplanes, the maintenance cover of the MZ-type 
SSCs, may crack during its service life due to pressure impulse 
fatigue. We are issuing this AD to prevent fatigue cracking of certain 
SSCs, which could result in hydraulic leakage and consequent loss of 
SSC function and loss of the associated hydraulic system. These 
conditions could affect all three hydraulic systems, which could result 
in reduced controllability of the airplane.

DATES: This AD becomes effective April 11, 2007.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of April 11, 
2007.

ADDRESSES: You may examine the AD docket on the Internet at http://
dms.dot.gov or in person at the Docket Management Facility, U.S. 
Department of Transportation, 400 Seventh Street SW., Nassif Building, 
Room PL-401, Washington, DC.
    Contact Airbus, 1 Rond Point Maurice Bellonte, 31707 Blagnac Cedex,

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the airworthiness directive (AD) docket on the 
Internet at http://dms.dot.gov or in person at the Docket Management 
Facility office between 9 a.m. and 5 p.m., Monday through Friday, 
except Federal holidays. The Docket Management Facility office 
(telephone (800) 647-5227) is located on the plaza level of the Nassif 
Building at the street address stated in the ADDRESSES section.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to certain Airbus Model 
A330 airplanes and Model A340-200 and -300 series airplanes. That NPRM 
was published in the Federal Register on December 28, 2006 (71 FR 
78102). That NPRM proposed to require inspecting to determine the part 
number of certain S4- and MZ-type spoiler servo-controls (SSCs). For 
certain other airplanes, that NPRM proposed to require inspecting to 
determine the part number of all SSCs. That NPRM also proposed to 
require replacing any affected SSC with a new SSC.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We received no comments on the NPRM or on the 
determination of the cost to the public.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD as proposed.

Costs of Compliance

    This AD affects about 27 airplanes of U.S. registry.
    It takes about 1 work hour per airplane to accomplish the 
inspection to determine the part number, at an average labor rate of 
$80 per work hour. Based on these figures, the estimated cost of the 
inspection required by this AD for U.S. operators is $2,160, or $80 per 
airplane.

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

[[Page 10058]]

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 have 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 DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979); and
    (3) 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.

basis indicated that the spoiler valve manifold of the S4-type 
spoiler servo controls (SSCs), and, on certain airplanes, the 
maintenance cover of the MZ-SSCs, may crack during its service life 
due to pressure impulse fatigue. We are issuing this AD to prevent 
fatigue cracking of certain SSCs, which could result in hydraulic 
leakage and consequent loss of SSC function and loss of the 
associated hydraulic system. These conditions could affect all three 
hydraulic systems, which could result in reduced controllability of 
the airplane.

the Accomplishment Instructions of the service bulletin.
    (i) If any SSC is installed in positions 2 through 6: Before the 
accumulation of 6,000 total flight cycles on the SSC since new, 
replace the SSC with a 138X-type SSC.
    (ii) If any SSC is installed in position 1: Before the 
accumulation of 11,000 total flight cycles on the SSC since new, 
replace the SSC with a 138X-type SSC.
    (iii) If the total flight cycles on any SSC exceed the total 
flight cycles specified in paragraph (f)(2)(i) or (f)(2)(ii) of this 
AD, as applicable, or if the total flight cycles are unknown: Before 
further flight, replace the SSC with a 138X-type SSC.
    (3) If any SSC has a missing identification plate, before 
further flight, identify the part number of the cylinder housing of 
the SSC by using a method approved by either the Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA; 
or the European Aviation Safety Agency (EASA) (or its delegated 
agent). Before further flight after determining the part number, 
accomplish the requirements specified in paragraph (f)(1) or (f)(2)

3.B.(1)(a) or 3.B.(2)(a) of the Accomplishment Instructions of the 
applicable service bulletin: No further action is required by this 
paragraph.
    (2) If the part number is identified in Table 1 of paragraph 
3.B.(1)(a) or 3.B.(2)(a) of the Accomplishment Instructions of the 
applicable service bulletin: Do the applicable actions specified in 
paragraphs (g)(2)(i), (g)(2)(ii), and (g)(2)(iii) of this AD in 
accordance with the Accomplishment Instructions of the applicable 
service bulletin.
    (i) If any SSC is installed in positions 2 through 6: Before the 
accumulation of 14,000 total flight cycles on the SSC since new, 
replace the SSC with a 138X-type SSC.
    (ii) If any SSC is installed in position 1: Before the 
accumulation of 15,000 total flight cycles on the SSC since new, 
replace the SSC with a 138X-type SSC.
    (iii) If the total flight cycles on any SSC exceed the total 
flight cycles specified in paragraph (g)(2)(i) or (g)(2)(ii) of this 
AD, as applicable, or if the total flight cycles are unknown: Before 
further flight, replace the SSC with a 138X-type SSC.
    (3) If any SSC has a missing identification plate, before 
further flight, identify the part number of the SSC cylinder housing 
by using a method approved by either the Manager, International 
Branch, ANM-116; or the EASA (or its delegated agent). Before 
further flight after determining the part number, accomplish the 
requirements specified in paragraph (g)(1) or (g)(2) of this AD, as 
applicable.
