14 CFR Part 39

[Docket No. FAA-2006-24640; Directorate Identifier 2006-CE-26-AD; 
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.

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

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

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:
