Amendment 39-14755; AD 2006-18-16]
RIN 2120-AA64
Airworthiness Directives; Raytheon Aircraft Company Model 390
Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Raytheon Aircraft Company Model 390 airplanes. This AD requires you to
inspect the spigot bearing, part number (P/N) MS14104-16, for the
proper position in the spigot fitting assembly and to install the wing
spigot bearing retainer kit, P/N 390-4304-0001. We are issuing this AD
to detect spigot bearings that are not positioned flush with the
fitting assembly. This condition could result in the spigot bearing
becoming disengaged from the fitting assembly, which could cause motion
between the wing and the fuselage and degrade the structural integrity
of the wing attachment to the fuselage. This could lead to wing
separation and loss of control of the airplane.
DATES: This AD becomes effective on October 13, 2006.
As of October 13, 2006, the Director of the Federal Register
approved the incorporation by reference of certain publications listed
in the regulation.
ADDRESSES: For service information identified in this AD, contact

SUPPLEMENTARY INFORMATION:
Discussion
On May 17, 2006, we issued a proposal to amend part 39 of the
Federal Aviation Regulations (14 CFR part 39) to include an AD that
would apply to certain Raytheon Aircraft Company Model 390 airplanes.
This proposal was published in the Federal Register as a notice of
proposed rulemaking (NPRM) on May 23, 2006 (71 FR 29595). The NPRM
proposed to require you to inspect the spigot bearing, P/N MS14104-16,
for the proper position in the spigot fitting assembly and to install
the wing spigot bearing retainer kit, P/N 390-4304-0001.
Comments
We provided the public the opportunity to participate in developing
this AD. We received no comments on the proposal or on the
determination of the cost to the public.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed
except for minor editorial corrections. We have determined that these
minor corrections:
Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
Costs of Compliance
We estimate that this AD affects 78 airplanes in the U.S. registry.
We estimate the following costs to do the installation of the
spigot bearing retainer kit, P/N 390-4304-0001:
----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on
Labor cost Parts cost airplane U.S. operators
----------------------------------------------------------------------------------------------------------------
8 work-hours x $80 per hour = $640.............................. $1,442 $2,082 $162,396
----------------------------------------------------------------------------------------------------------------
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 AD.
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 the 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 summary of the costs to comply with this AD (and
other
[[Page 52999]]
information as included in the Regulatory Evaluation) and placed it in
the AD Docket. You may get a copy of this summary by sending a request
to us at the address listed under ADDRESSES. Include ``Docket No. FAA-
2006-24640; Directorate Identifier 2006-CE-26-AD'' in your request.

Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the Federal Aviation Administration amends part 39 of the Federal
Aviation Regulations (14 CFR part 39) as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
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. FAA amends Sec. 39.13 by adding the following new AD:
2006-18-16 Raytheon Aircraft Company: Amendment 39-14755; Docket No.
FAA-2006-24640; Directorate Identifier 2006-CE-26-AD.
Effective Date
(a) This AD becomes effective on October 13, 2006.
Affected ADs
(b) None.
Applicability
(c) This AD affects Model 390 airplanes, serial numbers RB-1 and
RB-4 through RB-139, that are certificated in any category.
Unsafe Condition
(d) This AD is the result of two reports of the spigot bearing
not being positioned flush with the fitting assembly, but protruding
outside of the fitting assembly. The actions specified in this AD
are intended to detect spigot bearings that are not positioned flush
with the fitting assembly. This condition could result in the spigot
bearing becoming disengaged from the fitting assembly, which could
cause motion between the wing and the fuselage and degrade the
structural integrity of the wing attachment to the fuselage. This
could lead to wing separation and loss of control of the airplane.
Compliance
(e) To address this problem, you must do the following:
