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:
    To prevent the cockpit door windows separating from their frames, * 
* * We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective October 17, 2007.
    On October 17, 2007, 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 https://
dms.dot.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 
20590.

FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, 
Missouri 64106; telephone: (816) 329-4146; fax: (816) 329-4090.

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 July 9, 2007 (72 FR 
37124). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:
    To prevent the cockpit door windows separating from their frames, * 
* * The MCAI requires you to inspect the windscreen and cockpit door 
windows for signs of disbonding of the adhesive between the 
transparency and the composite window frame. If disbonding is evident, 
you must do the required modification.

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 40 work-hours per product to 
comply with basic requirements of this AD. The average labor rate is 
$80 per work-hour. Required parts will cost about $50 per product.
    Based on these figures, we estimate the cost of this AD to the U.S. 
operators to be $22,750 or $3,250 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:
    (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 https://
dms.dot.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.

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

2007-19-01 Pacific Aerospace Corporation, Ltd: Amendment 39-15191; 
Docket No. FAA-2007-27865; Directorate Identifier 2007-CE-039-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective October 
17, 2007.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Model 750XL airplanes, all serial 
numbers, certificated in any category, that have not incorporated 
Pacific Aerospace Limited Service Letter PACSL/XL/07-1, dated April 
18, 2007, with Pacific Aerospace LTD Drawing, 11-03129, Issue B or 
subsequent, in its entirety.

Subject

    (d) Air Transport Association of America (ATA) Code 56: Windows.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    To prevent the cockpit door windows separating from their 
frames, * * * The MCAI requires you to inspect the windscreen and 
cockpit door windows for signs of disbonding of the adhesive between 
the transparency and the composite window frame. If disbonding is 
evident, you must do the required modification.

Actions and Compliance

    (f) Unless already done, do the following actions:
    (1) Within the next 50 hours time-in-service (TIS) after October 
17, 2007 (the effective date of this AD) and thereafter at intervals 
not to exceed 50 hours TIS, inspect the windscreen and cockpit door 
windows for signs of disbonding of the adhesive between the 
transparency and the composite window frame following Pacific 
Aerospace Limited Mandatory Service Bulletin PACSB/XL/024 
(embodiment of modification PAC/XL/0276) and PAC Drawing No. 11-
03137, both dated February 20, 2007 (undated). If you find 
disbanding during any inspection required by this AD, before further 
flight, modify the windscreen and cockpit windows to incorporate 
mechanical fasteners following Pacific Aerospace Limited Mandatory 
Service Bulletin PACSB/XL/024 (embodiment of modification PAC/XL/
0276) and PAC Drawing No. 11-03137 both dated February 20, 2007.
    (2) Within the next 150 hours TIS after October 17, 2007 (the 
effective date of this AD) or within the next 6 months after October 
17, 2007 (the effective date of this AD), whichever occurs first, 
modify the windscreen and cockpit windows to incorporate mechanical 
fasteners following Pacific Aerospace Limited Mandatory Service 
Bulletin PACSB/XL/024 (embodiment of modification PAC/XL/0276) and 
PAC Drawing No. 11-03137 both dated February 20, 2007. The 
requirement of paragraph (f)(1) of this AD to do repetitive 
inspections is no longer necessary when the modification of 
paragraph (f)(2) of this AD is done.

FAA AD Differences

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