ACTION: Final rule. sroberts on PROD1PC70 with RULES AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A320 series airplanes. This AD requires replacing the carbon fiber reinforced plastic (CFRP) actuator fittings of the rudder with aluminum actuator fittings and doing related investigative and corrective actions. This AD results from rupture of a CFRP VerDate Aug<31>2005 18:36 Mar 22, 2007 Jkt 211001 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 A320 series airplanes. That NPRM was published in the Federal Register on December 15, 2006 (71 FR 75432). That NPRM proposed to require replacing the carbon fiber reinforced plastic (CFRP) actuator fittings of the rudder with aluminum actuator fittings and doing related investigative and corrective actions. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments received. Support for the NPRM Airbus supports the NPRM. PO 00000 Frm 00015 Fmt 4700 Sfmt 4700 13685 Request To Revise Discussion Section In the Discussion section of the NPRM, we stated that investigation revealed that the CFRP actuator fittings cannot sustain limit loads resulting from ground gust conditions due to design of the fitting. Airbus requests that we revise that statement to clarify that the CFRP actuator fittings ‘‘on the rudder side’’ cannot sustain limit ‘‘compression’’ loads resulting from ground gust conditions due to design of the fitting. We agree with Airbus’ statement. However, we have not changed the AD in this regard, since the Discussion section is not retained in the final rule. Clarification of Alternative Method of Compliance (AMOC) Paragraph We have revised this action to clarify the appropriate procedure for notifying the principal inspector before using any approved AMOC on any airplane to which the AMOC applies. Conclusion We have carefully reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD with the change described previously. We have determined that this change will neither increase the economic burden on any operator nor increase the scope of the AD. Costs of Compliance This AD affects about 38 airplanes of U.S. registry. The required action takes about 100 work hours per airplane, at an average labor rate of $80 per work hour. Required parts cost about $6,310 per airplane. Based on these figures, the estimated cost of the AD for U.S. operators is $543,780, or $14,310 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 safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition E:\FR\FM\23MRR1.SGM 23MRR1 13686 Federal Register / Vol. 72, No. 56 / Friday, March 23, 2007 / Rules and Regulations that is likely to exist or develop on products identified in this rulemaking action. 21733 or 21999 has been incorporated in production.

Airworthiness Directives; Airbus Model A320 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 A320 series airplanes. This AD requires replacing 
the carbon fiber reinforced plastic (CFRP) actuator fittings of the 
rudder with aluminum actuator fittings and doing related investigative 
and corrective actions. This AD results from rupture of a CFRP actuator 
fitting during maintenance. We are issuing this AD to prevent rupture 
of a rudder actuator fitting, which could result in reduced 
controllability of the airplane.

DATES: This AD becomes effective April 27, 2007.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of April 27, 
2007.

ADDRESSES: You may examine the AD docket on the Internet at https://
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, 
France, for service information identified in this AD.

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the airworthiness directive (AD) docket on the 
Internet at https://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 
A320 series airplanes. That NPRM was published in the Federal Register 
on December 15, 2006 (71 FR 75432). That NPRM proposed to require 
replacing the carbon fiber reinforced plastic (CFRP) actuator fittings 
of the rudder with aluminum actuator fittings and doing related 
investigative and corrective actions.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comments received.

Support for the NPRM

    Airbus supports the NPRM.

Request To Revise Discussion Section

    In the Discussion section of the NPRM, we stated that investigation 
revealed that the CFRP actuator fittings cannot sustain limit loads 
resulting from ground gust conditions due to design of the fitting. 
Airbus requests that we revise that statement to clarify that the CFRP 
actuator fittings ``on the rudder side'' cannot sustain limit 
``compression'' loads resulting from ground gust conditions due to 
design of the fitting. We agree with Airbus' statement. However, we 
have not changed the AD in this regard, since the Discussion section is 
not retained in the final rule.

Clarification of Alternative Method of Compliance (AMOC) Paragraph

    We have revised this action to clarify the appropriate procedure 
for notifying the principal inspector before using any approved AMOC on 
any airplane to which the AMOC applies.

Conclusion

    We have carefully reviewed the available data, including the 
comments received, and determined that air safety and the public 
interest require adopting the AD with the change described previously. 
We have determined that this change will neither increase the economic 
burden on any operator nor increase the scope of the AD.

Costs of Compliance

    This AD affects about 38 airplanes of U.S. registry. The required 
action takes about 100 work hours per airplane, at an average labor 
rate of $80 per work hour. Required parts cost about $6,310 per 
airplane. Based on these figures, the estimated cost of the AD for U.S. 
operators is $543,780, or $14,310 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 safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition

[[Page 13686]]

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.
