AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to certain Raytheon airplanes, that requires inspection of
the main landing gear (MLG) wheels to determine the part numbers of the
tie-bolt nuts, and replacement of nuts that have the incorrect part
number with nuts that have the correct part number. The actions
specified by this AD are intended to prevent separation of an MLG wheel
due to loose or missing tie-bolts or tie-bolt nuts, with consequent
damage to airplane structure or systems, decompression, loss of full
braking ability, or injury to personnel on the ground. This action is
intended to address the identified unsafe condition.
DATES: Effective May 8, 2003.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of May 8, 2003.
ADDRESSES: The service information referenced in this AD may be
obtained from Raytheon Aircraft Company, Department 62, PO Box 85,
Wichita, Kansas 67201-0085. This information may be examined at the
Federal Aviation Administration (FAA), Transport Airplane Directorate,
Rules Docket, 1601 Lind Avenue, SW., Renton, Washington; at the FAA,
Wichita Aircraft Certification Office, 1801 Airport Road, Room 100,
Mid-Continent Airport, Wichita, Kansas; or at the Office of the Federal
Register, 800 North Capitol Street, NW., suite 700, Washington, DC.
FOR FURTHER INFORMATION CONTACT: David Ostrodka, Aerospace Engineer,
Airframe Branch, ACE-118W, FAA, Wichita Aircraft Certification Office,

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to include an airworthiness
directive (AD) that is applicable to certain Raytheon airplanes was
published in the Federal Register on January 3, 2003 (68 FR 322). That
action proposed to require inspection of the main landing gear (MLG)
wheels to determine the part numbers of the tie-bolt nuts, and
replacement of nuts that have the incorrect part number with nuts that
have the correct part number.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. No comments were submitted in response
to the proposal or the FAA's determination of the cost to the public.
Conclusion
The FAA has determined that air safety and the public interest
require the adoption of the rule as proposed.
[[Page 16206]]
Cost Impact
There are approximately 166 airplanes of the affected design in the
worldwide fleet. The FAA estimates that 84 airplanes of U.S. registry
will be affected by this AD, that it will take approximately 1 work
hour per airplane to accomplish the required inspection, and that the
average labor rate is $60 per work hour. Based on these figures, the
cost impact of the AD on U.S. operators is estimated to be $5,040, or
$60 per airplane.
The cost impact figure discussed above is based on assumptions that
no operator has yet accomplished any of the requirements of this AD
action, and that no operator would accomplish those actions in the
future if this AD were not adopted. The cost impact figures discussed
in AD rulemaking actions represent only the time necessary to perform
the specific actions actually required by the AD. These figures
typically do not include incidental costs, such as the time required to
gain access and close up, planning time, or time necessitated by other
administrative actions. Manufacturer warranty remedies may be available
for labor costs associated with this proposed AD. As a result, the
costs attributable to the proposed AD may be less than stated above.
Regulatory Impact
The regulations adopted herein 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. Therefore, it
is determined that this final rule does not have federalism
implications under Executive Order 13132.
For the reasons discussed above, I certify that this action (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. A final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
from the Rules Docket at the location provided under the caption

Note 1: This AD applies to each airplane identified in the
preceding applicability provision, regardless of whether it has been
modified, altered, or repaired in the area subject to the
requirements of this AD. For airplanes that have been modified,
altered, or repaired so that the performance of the requirements of
this AD is affected, the owner/operator must request approval for an
[[Page 16207]]
alternative method of compliance in accordance with paragraph (d) of
this AD. The request should include an assessment of the effect of
the modification, alteration, or repair on the unsafe condition
addressed by this AD; and, if the unsafe condition has not been
eliminated, the request should include specific proposed actions to
address it.
Compliance: Required as indicated, unless accomplished
previously.
To prevent separation of a main landing gear (MLG) wheel due to
loose or missing tie-bolts or tie-bolt nuts, with consequent damage
to airplane structure or systems, decompression, loss of full
braking ability, or injury to personnel on the ground, accomplish
the following:
Inspection
(a) Within 10 landings or 12 days after the effective date of
this AD, whichever comes first, inspect the MLG wheels to determine
the part numbers (P/Ns) of the tie-bolt nuts; per Raytheon Service
Bulletin SB 32-3522, dated September 2002, excluding Service
Bulletin/Kit Drawing Report Fax.
Replacement
(b) If any tie-bolt nut having P/N NAS1804 is found installed
during the inspection required by paragraph (a) of this AD, before
further flight, replace the tie-bolt nut with a new nut having P/N
FN22A524, (or with a new tie-bolt nut having a Dunlop P/N H5227C-
5CW, SN407C-054, or LH13318-5, which are P/Ns authorized by
Raytheon); per Raytheon Service Bulletin SB 32-3522, dated September
2002, excluding Service Bulletin/Kit Drawing Report Fax.
Parts Installation
(c) As of the effective date of this AD, no person shall install
any MLG wheel having a tie-bolt nut with P/N NAS1804, on any
airplane.
Alternative Methods of Compliance
(d) An alternative method of compliance or adjustment of the
compliance time that provides an acceptable level of safety may be
used if approved by the Manager, Wichita Aircraft Certification
Office (ACO), FAA. Operators shall submit their requests through an
appropriate FAA Principal Maintenance Inspector, who may add
comments and then send it to the Manager, Wichita ACO.
Note 2: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the Wichita ACO.
Special Flight Permits
(e) Special flight permits may be issued in accordance with
Sec. Sec. 21.197 and 21.199 of the Federal Aviation Regulations (14
CFR 21.197 and 21.199) to operate the airplane to a location where
the requirements of this AD can be accomplished.
Incorporation by Reference
(f) Unless otherwise provided by this AD, the actions shall be
done per Raytheon Service Bulletin SB 32-3522, dated September 2002,
excluding Service Bulletin/Kit Drawing Report Fax. This
incorporation by reference was approved by the Director of the
Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part
51. Copies may be obtained from Raytheon Aircraft Company,
Department 62, PO Box 85, Wichita, Kansas 67201-0085. Copies may be
