Airworthiness Directives; Pacific Aerospace Corporation, Ltd 
Model 750XL Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD results from mandatory continuing 
airworthiness information (MCAI) issued 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:

    DCA/750XL/3A is prompted by a report from the manufacturer of 
the possibility that wiring loom protective sleeving is not fitted 
to aircraft S/N 107 through to 134. AD applicability revised to 
include aircraft up to S/N 134.
    To prevent fretting damage to the wiring loom that may lead to 
arcing in proximity to the fuel vent lines and the possibility of 
fire * * *.

We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective April 23, 2008.
    On April 23, 2008, the Director of the Federal Register approved 
the incorporation by reference of certain publications listed in this 
AD.

ADDRESSES: You may examine the AD docket on the Internet at http://
www.regulations.gov or in person at Document Management Facility, U.S. 
Department of Transportation, Docket Operations, M-30, West Building 
Ground Floor, Room W12-140, 1200 New Jersey Avenue, SE., Washington, DC

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on January 18, 2008 (73 
FR 3417). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    DCA/750XL/3A is prompted by a report from the manufacturer of 
the possibility that wiring loom protective sleeving is not fitted 
to aircraft S/N 107 through to 134. AD applicability revised to 
include aircraft up to S/N 134.
    To prevent fretting damage to the wiring loom that may lead to 
arcing in proximity to the fuel vent lines and the possibility of 
fire * * *.

Comments

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

Conclusion

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

Differences Between this 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 required 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 AD.

Costs of Compliance

    We estimate that this AD will affect 7 products of U.S. registry. 
We also estimate that it will take about 0.5 work-hour per product to 
comply with basic requirements of this AD. The average labor rate is 
$80 per work-hour. Required parts will cost about $30 per product.
    Based on these figures, we estimate the cost of this AD to the U.S. 
operators to be $490 or $70 per product.

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 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 this AD:

[[Page 14666]]

    (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.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://
www.regulations.gov; or in person at the Docket Management Facility 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Office (telephone (800) 647-5527) is in the ADDRESSES 
section. Comments will be available in the AD docket shortly after 
receipt.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

2008-06-16 Pacific Aerospace Corporation, Ltd.: Amendment 39-15428; 
Docket No. FAA-2008-0034; Directorate Identifier 2007-CE-097-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective April 
23, 2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Model 750XL airplanes, serial numbers 102 
through 134, certificated in any category.

    Note 1: The applicability of this AD takes precedence over 
Pacific Aerospace Corporation Limited Mandatory Service Bulletin 
PACSB/XL/009, issue 2, revised July 23, 2004.

Subject

    (d) Air Transport Association of America (ATA) Code 39: 
Electrical Wiring.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    DCA/750XL/3A is prompted by a report from the manufacturer of 
the possibility that wiring loom protective sleeving is not fitted 
to aircraft S/N 107 through to 134. AD applicability revised to 
include aircraft up to S/N 134.
    To prevent fretting damage to the wiring loom that may lead to 
arcing in proximity to the fuel vent lines and the possibility of 
fire, inspect the main wiring loom on the right hand side of the 
aircraft adjacent to the frames at station 114.34'' and 118.84'', 
per PACSB/XL/009 issue 2, to ensure that two pieces of protective 
sleeving are fitted.

The effectivity of the service information is serial number (S/N) 
102 through 106. The MCAI expanded the applicability to S/N 102 
through 134.

Actions and Compliance

    (f) Unless already done, do the following actions:
    (1) Within the next 100 hours time-in-service (TIS) after April 
23, 2008 (the effective date of this AD), inspect the main wiring 
loom on the right hand side of the aircraft adjacent to the frames 
at station 114.34'' and 118.84'' to ensure there are two pieces of 
protective sleeving installed following Pacific Aerospace 
Corporation Limited Mandatory Service Bulletin PACSB/XL/009, issue 
2, revised July 23, 2004.
    (2) If you find the protective sleeves are missing as a result 
of the inspection required by paragraph (f)(1) of this AD, before 
further flight, install protective sleeves following Pacific 
Aerospace Corporation Mandatory Service Bulletin PACSB/XL/009, issue 
2, revised July 23, 2004.

FAA AD Differences

    Note 2: This AD differs from the MCAI and/or service information 
as follows: No differences.
