ACTION: Airworthiness directives:
DOCUMENT ACTION: Final rule.
SUBJECT CATEGORY:
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
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.
DOCUMENT SUMMARY:
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Sabreliner Model NA26540, NA26550, NA26560, NA26570, and NA26580 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.
SUMMARY:
Sabreliner,
SUPPLEMENTAL 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) 6475227) 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 731803, amendment 39 3201 (43 FR 19208, May 4, 1978). The existing AD applies to certain Rockwell International Model NA26540, NA26550, NA26560, NA265 70, and NA26580 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.
[[Page 73924]]
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. List of Subjects in 14 CFR Part 39

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

Note 1: For the purposes of this AD, a general visual inspection
is: ``A visual examination of an interior or exterior area,
installation, or assembly to detect obvious damage, failure, or
irregularity. This level of inspection is made from within touching
distance unless otherwise specified. A mirror may be necessary to
ensure visual access to all surfaces in the inspection area. This
level of inspection is made under normally available lighting
conditions such as daylight, hangar lighting, flashlight, or
droplight and may require removal or opening of access panels or
doors. Stands, ladders, or platforms may be required to gain proximity to the area being checked.''
Corrective Actions
(k) If any fuel leak, break in the surface finish, corrosion, or
cracking is found during any inspection required by paragraph (j) of
this AD: Before further flight, replace the subject part with a new
or serviceable part, or repair the subject part in accordance with a
method approved by the Manager, Wichita ACO. Where Sabreliner NA265 Service Bulletin 832, revised January 31, 2005, specifies
contacting Sabreliner for an engineering analysis: Before further
