[FR Doc. 06–2380 Filed 3–9–06; 8:45 am] BILLING CODE 3410–34–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2006–23579; Directorate Identifier 2006–CE–02–AD] RIN 2120–AA64 Airworthiness Directives; Pacific Aerospace Corporation Ltd. 750XL Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Notice of proposed rulemaking (NPRM). dsatterwhite on PROD1PC61 with PROPOSALS AGENCY: SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 2005–26–53; Amendment 39–14451, which applies to all Pacific Aerospace Corporation Ltd. (PAC) 750XL airplanes. AD 2005–26–53 currently requires you to insert text into the Limitations Section of the Airplane Flight Manual (AFM) that reduces the maximum takeoff weight from 7,500 pounds to 7,125 pounds. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for New Zealand and the FAA’s decision that the actions correct an unsafe condition. Consequently, this proposed AD would require you to remove rivets that have not been fully age hardened and replace them with bolts, washers, and nuts in specific locations where reduction in rivet strength affects overall structural capability. This proposed AD retains the actions of the previous AD until the rivets are replaced with the bolts, washers, and nuts. We are issuing this proposed AD so that wing ultimate load requirements are met. If wing ultimate load requirements are not met, wing failure could result with subsequent loss of control of the airplane. DATES: We must receive comments on this proposed AD by April 12, 2006. ADDRESSES: Use one of the following addresses to comment on this proposed AD: • DOT Docket Web site: Go to https://dms.dot.gov and follow the VerDate Aug<31>2005 20:29 Mar 09, 2006 Jkt 208001 instructions for sending your comments electronically. • Government-wide rulemaking web site: Go to https://www.regulations.gov and follow the instructions for sending your comments electronically. • Mail: Docket Management Facility; U.S. Department of Transportation, 400 Seventh Street, SW., Nassif Building, Room PL–401, Washington, DC 20590– 0001. • Fax: 1–202–493–2251. • Hand Delivery: Room PL–401 on the plaza level of the Nassif Building, 400 Seventh Street, SW., Washington, DC, between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 12305 Examining the Dockets Where can I go to view the docket information? You may examine the docket that contains the proposal, any comments received and any final disposition on the Internet at https:// dms.dot.gov, or in person at the DOT Docket Offices between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Office (telephone 1–800–647–5227) is located on the plaza level of the Department of Transportation Nassif Building at the street address stated in ADDRESSES. Comments will be available in the AD docket shortly after the Docket Management Facility receives them. Discussion Has FAA taken any action to this point? Some critical rivets that were not fully age-hardened were used in specific locations where the reduction in rivet strength affects the overall structural capability. The unsafe condition caused us to issue AD 2005–26–53, Amendment 39–14451 (71 FR 2453, January 17, 2006). AD 2005–26–53 currently requires you to insert text into the Limitations Section of the Airplane Flight Manual (AFM) that reduces the maximum takeoff weight from 7,500 pounds to 7,125 pounds. What has happened since AD 2005– 26–53 to initiate this proposed AD action? The Civil Aviation Authority (CAA), which is the airworthiness authority for New Zealand, recently notified FAA of the need to change AD 2005–26–53. The CAA reports that the manufacturer has now specified bolts, washers, and nuts to replace the rivets located in critical locations where reduction in rivet strength is critical. After replacing the rivets that have not been fully age hardened with the bolts, washers, and nuts, the wings of these airplanes will meet the ultimate load requirements for a maximum takeoff weight of 7,500 pounds. What is the potential impact if FAA took no action? This condition, if not corrected, could result in the wing not meeting ultimate load requirements. Wing failure could result with subsequent loss of control of the airplane. Relevant Service Information Is there service information that applies to this subject? We have reviewed Pacific Aerospace Corporation, Ltd. Service Bulletin No. PACSB/XL/018 Issue 3, issued December 23, 2005, and amended January 16, 2006. What are the provisions of this service information? The service information describes procedures for: E:\FR\FM\10MRP1.SGM 10MRP1 12306 Federal Register / Vol. 71, No. 47 / Friday, March 10, 2006 / Proposed Rules • Removing rivets, part number (P/N) MS20470 DD6; and • installing bolts (P/N NAS 6203–7X or NAS 6203–6X), washers (P/N AN960–10), and nuts (P/N MS21044N3) in place of the rivets. What action did the CAA take? The CAA classified this service bulletin as mandatory and issued New Zealand AD Number DCA/750XL/7A, dated December 24, 2005, to ensure the continued airworthiness of these airplanes in New Zealand. Did the CAA inform the United States under the bilateral airworthiness agreement? These PAC Model 750XL airplanes are manufactured in New Zealand and are type-certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Under this bilateral airworthiness agreement, the New Zealand CAA has kept us informed of the situation described above. FAA’s Determination and Requirements of the Proposed AD Why have we determined AD action is necessary and what would this proposed AD require? We are proposing this AD to address an unsafe condition that we determined is likely to exist or develop on other products of this same type design. This proposed AD would supersede AD 2005–26–53 with a new AD that would require you to remove certain rivets and replace them with bolts, washers, and nuts in specific locations where reduction in rivet strength is critical. This proposed AD would require you to use the service information described previously to perform these actions. Differences Between This Proposed AD and Service Information Are there differences between the requirements of this proposed AD and what is contained in the service information? This proposed AD has a different compliance time for the replacement of the rivets than the compliance time in the service information. The requirements of this proposed AD, if adopted as a final rule, would take precedence over the provisions in the service information. Costs of Compliance How many airplanes would this proposed AD impact? We estimate that this proposed AD affects 5 airplanes in the U.S. registry. What would be the cost impact of this proposed AD on owners/operators of the affected airplanes? We estimate the following costs to do this proposed replacement: Labor cost Parts cost Total cost per airplane Total cost on U.S. operators 32 workhours × $80 per hour = $2,560 ....................................................................................... $519 $3,079 $15,395 Authority for This Rulemaking What authority does FAA have for issuing this rulemaking action? 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. dsatterwhite on PROD1PC61 with PROPOSALS Regulatory Findings Would this proposed AD impact various entities? We have 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 VerDate Aug<31>2005 20:29 Mar 09, 2006 Jkt 208001 responsibilities among the various levels of government. For the reasons discussed above, I certify that the 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. See the ADDRESSES section for a location to examine the regulatory evaluation. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety.

Airworthiness Directives; Pacific Aerospace Corporation Ltd. 
750XL Airplanes

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2005-26-53; Amendment 39-14451, which applies to all Pacific Aerospace 
Corporation Ltd. (PAC) 750XL airplanes. AD 2005-26-53 currently 
requires you to insert text into the Limitations Section of the 
Airplane Flight Manual (AFM) that reduces the maximum takeoff weight 
from 7,500 pounds to 7,125 pounds. This proposed AD results from 
mandatory continuing airworthiness information (MCAI) issued by the 
airworthiness authority for New Zealand and the FAA's decision that the 
actions correct an unsafe condition. Consequently, this proposed AD 
would require you to remove rivets that have not been fully age 
hardened and replace them with bolts, washers, and nuts in specific 
locations where reduction in rivet strength affects overall structural 
capability. This proposed AD retains the actions of the previous AD 
until the rivets are replaced with the bolts, washers, and nuts. We are 
issuing this proposed AD so that wing ultimate load requirements are 
met. If wing ultimate load requirements are not met, wing failure could 
result with subsequent loss of control of the airplane.

DATES: We must receive comments on this proposed AD by April 12, 2006.

Facility receives them.

Discussion

    Has FAA taken any action to this point? Some critical rivets that 
were not fully age-hardened were used in specific locations where the 
reduction in rivet strength affects the overall structural capability. 
The unsafe condition caused us to issue AD 2005-26-53, Amendment 39-
14451 (71 FR 2453, January 17, 2006). AD 2005-26-53 currently requires 
you to insert text into the Limitations Section of the Airplane Flight 
Manual (AFM) that reduces the maximum takeoff weight from 7,500 pounds 
to 7,125 pounds.
    What has happened since AD 2005-26-53 to initiate this proposed AD 
action? The Civil Aviation Authority (CAA), which is the airworthiness 
authority for New Zealand, recently notified FAA of the need to change 
AD 2005-26-53. The CAA reports that the manufacturer has now specified 
bolts, washers, and nuts to replace the rivets located in critical 
locations where reduction in rivet strength is critical. After 
replacing the rivets that have not been fully age hardened with the 
bolts, washers, and nuts, the wings of these airplanes will meet the 
ultimate load requirements for a maximum takeoff weight of 7,500 
pounds.
    What is the potential impact if FAA took no action? This condition, 
if not corrected, could result in the wing not meeting ultimate load 
requirements. Wing failure could result with subsequent loss of control 
of the airplane.

Relevant Service Information

    Is there service information that applies to this subject? We have 
reviewed Pacific Aerospace Corporation, Ltd. Service Bulletin No. 
PACSB/XL/018 Issue 3, issued December 23, 2005, and amended January 16, 
2006.
    What are the provisions of this service information? The service 
information describes procedures for:

[[Page 12306]]

     Removing rivets, part number (P/N) MS20470 DD6; and
     installing bolts (P/N NAS 6203-7X or NAS 6203-6X), washers 
(P/N AN960-10), and nuts (P/N MS21044N3) in place of the rivets.
    What action did the CAA take? The CAA classified this service 
bulletin as mandatory and issued New Zealand AD Number DCA/750XL/7A, 
dated December 24, 2005, to ensure the continued airworthiness of these 
airplanes in New Zealand.
    Did the CAA inform the United States under the bilateral 
airworthiness agreement? These PAC Model 750XL airplanes are 
manufactured in New Zealand and are type-certificated for operation in 
the United States under the provisions of section 21.29 of the Federal 
Aviation Regulations (14 CFR 21.29) and the applicable bilateral 
airworthiness agreement.
    Under this bilateral airworthiness agreement, the New Zealand CAA 
has kept us informed of the situation described above.

FAA's Determination and Requirements of the Proposed AD

    Why have we determined AD action is necessary and what would this 
proposed AD require? We are proposing this AD to address an unsafe 
condition that we determined is likely to exist or develop on other 
products of this same type design. This proposed AD would supersede AD 
2005-26-53 with a new AD that would require you to remove certain 
rivets and replace them with bolts, washers, and nuts in specific 
locations where reduction in rivet strength is critical. This proposed 
AD would require you to use the service information described 
previously to perform these actions.

Differences Between This Proposed AD and Service Information

    Are there differences between the requirements of this proposed AD 
and what is contained in the service information? This proposed AD has 
a different compliance time for the replacement of the rivets than the 
compliance time in the service information. The requirements of this 
proposed AD, if adopted as a final rule, would take precedence over the 
provisions in the service information.

Costs of Compliance

    How many airplanes would this proposed AD impact? We estimate that 
this proposed AD affects 5 airplanes in the U.S. registry.
    What would be the cost impact of this proposed AD on owners/
operators of the affected airplanes? We estimate the following costs to 
do this proposed replacement:

----------------------------------------------------------------------------------------------------------------
                                                                                 Total cost per   Total cost on
                          Labor cost                              Parts cost        airplane      U.S. operators

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

Authority for This Rulemaking

    What authority does FAA have for issuing this rulemaking action? 
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

    Would this proposed AD impact various entities? We have 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 that the 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. See the ADDRESSES section for a location 
to examine the regulatory evaluation.

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 Federal Aviation Administration 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 removing Airworthiness Directive 
(AD) 2005-26-53, Amendment 39-14451, and adding the following new 
airworthiness directive:

Pacific Aerospace Corporation Ltd.: Docket No. FAA-2006-23579; 
Directorate Identifier 2006-CE-02-AD.

When Is the Last Date I Can Submit Comments on This Proposed AD?

    (a) The Federal Aviation Administration (FAA) must receive 
comments on this proposed airworthiness directive (AD) action by 
April 12, 2006.

What Other ADs Are Affected by This Action?

    (b) This AD supersedes AD 2005-26-53; Amendment 39-14451.

What Airplanes Are Affected by This AD?

    (c) This AD affects Model 750XL airplanes, all serial numbers 
that are certificated in any category.

What Is the Unsafe Condition Presented in This AD?

    (d) This AD results from some critical rivets on the wing not 
being fully age-hardened and being installed in specific locations 
where reduction in rivet strength reduces wing strength. The actions 
specified in this AD are intended to ensure wing ultimate load 
requirements are met. If wing ultimate load requirements are not 
met, wing failure could result with subsequent loss of control of 
the airplane.
