Discussion The Civil Aviation Authority of New Zealand (CAA), which is the aviation authority for New Zealand, has issued DCA/FU24/177, dated November 28, 2007, to correct an unsafe condition for the specified products. The MCAI states: This AD is prompted by reports of loosening rivets securing the threaded inserts in the ends of the aileron control pushrods P/N 08–24015–1. Aileron push-pull rods P/ N 08–24015–1 have been installed on aircraft embodying PAC/FU/0340. The MCAI requires an initial and repetitive inspection of the aileron and elevator control push-rods and requires corrective action as necessary. E:\FR\FM\24JAP1.SGM 24JAP1 4128 Federal Register / Vol. 73, No. 16 / Thursday, January 24, 2008 / Proposed Rules You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Pacific Aerospace Limited has issued PACSB/FU/091, Issue 2, dated November 12, 2007. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of the 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 this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. Differences Between This Proposed AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the proposed AD. mstockstill on PROD1PC66 with PROPOSALS Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 2 products of U.S. registry. We also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $160, or $80 per product. In addition, we estimate that any necessary follow-on actions would take about 5 work-hours and require parts costing $100, for a cost of $500 per product. We have no way of determining the number of products that may need these actions. VerDate Aug<31>2005 18:55 Jan 23, 2008 Jkt 214001 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 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); 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 proposed AD and placed it in the AD docket. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, 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.

ACTION: Notice of proposed rulemaking (NPRM). mstockstill on PROD1PC66 with PROPOSALS AGENCY: SUMMARY: The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Airbus Model A319, A320, and A321 series airplanes equipped with certain Litton air data inertial reference units (ADIRUs). The existing AD currently requires modifying the shelf (floor panel) above ADIRU 3, modifying the VerDate Aug<31>2005 18:55 Jan 23, 2008 Jkt 214001 polycarbonate guard that covers the ADIRUs for certain airplanes, and modifying the ladder located in the avionics compartment for certain airplanes. This proposed AD would require those modifications on additional airplanes. This proposed AD would also require replacing all three ADIRUs with improved ADIRUs. This proposed AD also adds Model A318 series airplanes to the applicability. This proposed AD results from reports that ‘‘NAV IR FAULT’’ messages have occurred during takeoff due to failure of an ADIRU and subsequent analysis showing that the shelf modification has not sufficiently addressed failure of an ADIRU. We are proposing this AD to prevent failure of an ADIRU during flight, which could result in loss of one source of critical attitude and airspeed data and reduce the ability of the flightcrew to control the airplane.

Discussion On December 12, 2003, we issued AD 2003–26–03, amendment 39–13399 (68 FR 74172, December 23, 2003), for certain Airbus Model A319, A320, and A321 series airplanes equipped with certain Litton air data inertial reference units (ADIRUs). That AD requires modifying the shelf (floor panel) above ADIRU 3, and, for certain airplanes, modifying the polycarbonate guard that covers the ADIRUs, and the ladder located in the avionics compartment, as applicable. That AD resulted from reports that ‘‘NAV IR FAULT’’ messages have occurred during takeoff due to failure of ADIRU 3 on several Model A319, A320, and A321 series airplanes. We issued that AD to prevent failure of ADIRU 3 during flight, which could result in loss of one source of critical attitude and airspeed data and reduce the ability of the flightcrew to control the airplane. Actions Since Existing AD Was Issued Since we issued AD 2003–26–03, the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, notified us that further analysis has shown that modifying the ADIRU shelf has not sufficiently addressed the unsafe condition. The clearance between the shelf and ADIRUs is still too small. Consequently, vibration during takeoff could cause the shelf to hit the top of an ADIRU, leading to loss of parameters (attitude, vertical speed, ground speed, etc.). The EASA has determined that, in addition to E:\FR\FM\24JAP1.SGM 24JAP1

continuing airworthiness information (MCAI) originated by an aviation 
authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as:

    This AD is prompted by reports of loosening rivets securing the 
threaded inserts in the ends of the aileron control pushrods P/N 08-
24015-1. Aileron push-pull rods P/N 08-24015-1 have been installed 
on aircraft embodying PAC/FU/0340.

The proposed AD would require actions that are intended to address the 
unsafe condition described in the MCAI.

Discussion

    The Civil Aviation Authority of New Zealand (CAA), which is the 
aviation authority for New Zealand, has issued DCA/FU24/177, dated 
November 28, 2007, to correct an unsafe condition for the specified 
products. The MCAI states:

    This AD is prompted by reports of loosening rivets securing the 
threaded inserts in the ends of the aileron control pushrods P/N 08-
24015-1. Aileron push-pull rods P/N 08-24015-1 have been installed 
on aircraft embodying PAC/FU/0340.

The MCAI requires an initial and repetitive inspection of the aileron 
and elevator control push-rods and requires corrective action as 
necessary.

[[Page 4128]]

    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Pacific Aerospace Limited has issued PACSB/FU/091, Issue 2, dated 
November 12, 2007. The actions described in this service information 
are intended to correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of the 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 this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Differences Between This Proposed AD and the MCAI or Service 
Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a NOTE within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 2 products of U.S. registry. We also estimate that 
it would take about 1 work-hour per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $80 per 
work-hour.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $160, or $80 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 5 work-hours and require parts costing $100, for a cost of 
$500 per product. We have no way of determining the number of products 
that may need these actions.

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 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); 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 proposed AD and placed it in the AD docket.

    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 AD:

Pacific Aerospace Limited: Docket No. FAA-2008-0055; Directorate 
Identifier 2007-CE-099-AD.

Comments Due Date

    (a) We must receive comments by February 25, 2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to models FU24-954 and FU24A-954 airplanes, 
all serial numbers, certificated in any category.

Subject

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

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    This AD is prompted by reports of loosening rivets securing the 
threaded inserts in the ends of the aileron control pushrods P/N 08-
24015-1. Aileron push-pull rods P/N 08-24015-1 have been installed 
on aircraft embodying PAC/FU/0340.

The MCAI requires an initial and repetitive inspection of the 
aileron and elevator control push-rods and requires corrective 
action as necessary.

Actions and Compliance

    (f) Unless already done, do the following actions:
    (1) Within the next 50 hours time-in-service (TIS) after the 
effective date of this AD, inspect the pushrod ends on the aileron 
and elevator control pushrods part number (P/N) 08-24015-1 following 
Pacific Aerospace Limited Service Bulletin No. PACSB/FU/091, Issue 
2, dated November 12, 2007. Repetitively inspect thereafter at 
intervals not to exceed 150 hours TIS.
    (2) Before further flight after any inspection where any rivets 
are found on aileron and elevator control pushrods P/N 08-24015-1 
that have detectable play between the pushrod and the insert or 
evidence of working rivets, replace the rivets following Pacific 
Aerospace Limited Service Bulletin No. PACSB/FU/091, Issue 2, dated 
November 12, 2007.

    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority
