Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2008-0136; Directorate Identifier 2007-CE-104-AD; 
Amendment 39-15449; AD 2008-07-08]

Airworthiness Directives; Pacific Aerospace Limited 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 \1/8\-inch 
rivets installed in place of the correct \5/32\-inch rivets that secure 
the horizontal tail surface load transfer angles to the rearmost 
fuselage frame at Station 384.62. We are issuing this AD to require 
actions to correct the unsafe condition on these products.

DATES: This AD becomes effective April 30, 2008.
    On April 30, 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

FOR FURTHER INFORMATION CONTACT: Karl Schletzbaum, Aerospace Engineer, 
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 February 5, 2008 (73 
FR 6636). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI describes the unsafe condition as \1/8\-
inch rivets installed in place of the correct \5/32\-inch rivets that 
secure the horizontal tail surface load transfer angles to the rearmost 
fuselage frame at Station 384.62.

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.
    Based on these figures, we estimate the cost of this AD to the U.S. 
operators to be $280 or $40 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 2.0 work-hours and require parts costing $10, for a cost of 
$170 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 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;

[[Page 15875]]

    (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

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:

2008-07-08 Pacific Aerospace Limited: Amendment 39-15449; Docket No. 
FAA-2008-0136; Directorate Identifier 2007-CE-104-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective April 
30, 2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to 750XL airplanes, serial numbers 101 
through 108, certificated in any category.

Subject

    (d) Air Transport Association of America (ATA) Code 51: 
Structures.

Reason

    (e) The MCAI describes the unsafe condition as \1/8\-inch rivets 
installed in place of the correct \5/32\-inch rivets that secure the 
horizontal tail surface load transfer angles to the rearmost 
fuselage frame at Station 384.62. The MCAI requires you to inspect 
for the correct size rivets and if the wrong size rivets are 
installed, replace the rivets with the correct size rivets.

Actions and Compliance

    (f) Unless already done, do the following actions:
    (1) Within 100 hours time-in-service (TIS) after April 30, 2008 
(the effective date of this AD), inspect to ensure that \1/8\-inch 
rivets are not installed in place of the correct \5/32\-inch rivets 
that secure the horizontal tail surface load transfer angles to the 
rearmost fuselage frame at Station 384.62 following Pacific 
Aerospace Corporation Limited Mandatory Service Bulletin No. PACSB/
XL/010, dated: July 23, 2004.
    (2) Before further flight, if you find undersized rivets are 
installed as a result of the inspection required by paragraph (f)(1) 
of this AD, replace the undersized rivets with the correct \5/32\-
inch rivets following Pacific Aerospace Corporation Limited Service 
Mandatory Bulletin No. PACSB/XL/010, dated: July 23, 2004.

FAA AD Differences

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

FSDO.
    (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 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
    (3) Reporting Requirements: For any reporting requirement in 
this AD, under the provisions of the Paperwork Reduction Act (44
