Airworthiness Directives; Sabreliner Model NA-265, NA-265-20, NA-
265-30, NA-265-40, NA-265-50, NA-265-60, NA-265-65, NA-265-70, and NA-
265-80 Series Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD), which applies to certain Sabreliner Model NA-265-40, NA-265-50, 
NA-265-60, NA-265-70, and NA-265-80 series airplanes. That AD currently 
requires repetitive inspections for discrepancies in the front and rear 
spars of the wing in the area of the wing center section, and in the 
lugs on the rear spar and wing trailing edge panel rib, and corrective 
actions if necessary. This new AD expands the applicability of the 
existing AD and requires new repetitive inspections for fuel leaks of 
the front and rear spars of the wing, and for discrepancies in the 
front and rear spars of the wing in the area of the wing center 
section, and in the lugs on the rear spar and wing trailing edge panel 
rib. This AD also requires related investigative and corrective 
actions, if necessary. This AD results from reports of cracking in the 
upper and lower flanges of the front and rear spars of the wing near 
the wing center section, and in the lugs on the rear spar. We are 
issuing this AD to detect and correct cracking or other discrepancies 
in these areas, which could result in structural failure of the wing.

DATES: This AD becomes effective January 18, 2006.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of January 18, 
2006.

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the airworthiness directive (AD) docket on the 
Internet at http://dms.dot.gov or in person at the Docket Management 
Facility office between 9 a.m. and 5 p.m., Monday through Friday, 
except Federal holidays. The Docket Management Facility office 
(telephone (800) 647-5227) is located on the plaza level of the Nassif 
Building at the street address stated in the ADDRESSES section.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that supersedes AD 73-18-03, amendment 39-
3201 (43 FR 19208, May 4, 1978). The existing AD applies to certain 
Rockwell International Model NA-265-40, NA-265-50, NA-265-60, NA-265-
70, and NA-265-80 series airplanes. That NPRM was published in the 
Federal Register on September 14, 2005 (70 FR 54318). (A correction of 
that NPRM was published in the Federal Register on September 30, 2005 
(70 FR 57222).) That NPRM proposed to expand the applicability of the 
existing AD and require new repetitive inspections for fuel leaks of 
the front and rear spars of the wing, and for discrepancies in the 
front and rear spars of the wing in the area of the wing center 
section, and in the lugs on the rear spar and wing trailing edge panel 
rib. That NPRM also proposed to require related investigative and 
corrective actions, if necessary.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. No comments have been received on the NPRM or 
on the determination of the cost to the public.

Clarification of Alternative Method of Compliance (AMOC) Paragraph

    We have revised this action to clarify the appropriate procedure 
for notifying the principal inspector before using any approved AMOC on 
any airplane to which the AMOC applies.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD with the 
change described previously. We have determined that this change will 
neither increase the economic burden on any operator nor increase the 
scope of the AD.

Costs of Compliance

    There are about 77 airplanes of the affected design in the 
worldwide fleet. This AD affects about 43 airplanes of U.S. registry.
    The inspection specified in this AD takes about 12 work hours per 
airplane, per inspection cycle, at an average labor rate of $65 per 
work hour. Based on these figures, the estimated cost of the actions 
specified in this AD for U.S. operators is $33,540, or $780 per 
airplane, per inspection cycle.

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 have 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 that 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. See the ADDRESSES 
section for a location to examine the regulatory evaluation.
