Airworthiness Directives; Alpha Aviation Design Limited (Type
Certificate No. A48EU Previously Held by APEX Aircraft and AVIONS
PIERRE ROBIN) Model R2160 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 failure of the wing structure and assembly components due to undetected fatigue and corrosion * * *
We are issuing this AD to require actions to correct the unsafe condition on these products.
DATES: This AD becomes effective May 27, 2008.
On May 27, 2008, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental 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 6634). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:
To prevent failure of the wing structure and assembly components due to undetected fatigue and corrosion * * *
The MCAI requires that you inspect the wing structure and fuselage attachment and repair any defects that you find.
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
Based on the service information, we estimate that this AD will affect 9 products of U.S. registry. We also estimate that it will take about 15 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 $1,326 per product.
Based on these figures, we estimate the cost of this AD to the U.S. operators to be $22,734 or $2,526 per product.
We have no way to determine what aircraft will need replacement parts that may be required based on the results of any inspection.
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 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.

Service Bulletin No. 123, revision 3, dated December 23, 1999. Use the following compliance times for the inspection:
(i) For airplanes with less than 4,000 hours time-in-service
(TIS): When the airplane reaches a total of 3,500 hours TIS or within the next 100 hours TIS after May 27, 2008 (the effective date of this AD), whichever occurs later, and thereafter at intervals not to exceed 750 hours TIS.
(ii) For airplanes with 4,000 hours TIS or more that have not complied with the special instruction in paragraph E of Avions
Pierre Robin Service Bulletin No. 123, revision 2, dated November 14, 1995: Within the next 100 hours TIS after May 27, 2008 (the effective date of this AD) and thereafter at intervals not to exceed 750 hours TIS.
(iii) For airplanes with 4,000 hours TIS or more that have complied with the special instruction in paragraph E of Avions
Pierre Robin Service Bulletin No. 123, revision 2, dated November 14, 1995: Within the next 750 hours TIS after May 27, 2008 (the effective date of this AD) and thereafter at intervals not to exceed 750 hours TIS.
(2) When the airplane reaches a total of 3,500 hours TIS with original wing-to-fuselage bolts installed or 3,500 hours TIS of an airplane since new bolts have been installed or within the next 100 hours TIS after May 27, 2008 (the effective date of this AD), whichever occurs later, do a non-destructive inspection of the wing- to-fuselage retaining bolts and replace any bolts that do not pass this inspection following instruction No. 2 in Robin Aviation
Service Bulletin No. 123, revision 3, dated December 23, 1999.
Thereafter, repetitively inspect wing-to-fuselage retaining bolts and replace any bolts that do not pass this inspection every 750 hours TIS following instruction No. 2 in Robin Aviation Service
Bulletin No. 123, revision 3, dated December 23, 1999.
Note 1: The requirement for a 3,500-hour inspection is a time since new or time since installation (that is, the TIS of new bolts).
(3) Within the next 50 hours TIS after re-assembling the wing and thereafter at intervals not to exceed 100 hours TIS, inspect the wing-to-fuselage retaining bolts for correct torque settings following instruction No. 3 in Robin Aviation Service Bulletin No. 123, revision 3, dated December 23, 1999. The required torque value is 22 ft-lb with nut part number 95.24.39.010. Tighten to 16 ft-lb
