Federal Aviation Administration
14 CFR Part 39
[Docket No. FAA 2004-19119; Directorate Identifier 2004-CE-26-AD;
Amendment 39-13903; AD 2004-25-15]
RIN 2120-AA64
Airworthiness Directives; Raytheon Aircraft Company, Model 390,
Premier 1 Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA adopts a new airworthiness directive (AD) for certain
Raytheon Aircraft Company, Model 390, Premier 1 airplanes. This AD
requires you to inspect the routing and security of the left and right
main landing gear (MLG) squat switch wire harness installations for
damage, repair any damage or replace components, and reinstall the
squat switch wire harness. We are issuing this AD to prevent damage to
the wire harnesses, which could result in loss of pressurization, loss
of transponder responses to interrogations, and failure of other
systems utilizing air/ground status signals. This failure could lead to
loss of control of the airplane.
DATES: This AD becomes effective on January 18, 2005.
As of January 18, 2005, the Director of the Federal Register
approved the incorporation by reference of certain publications listed
in the regulation.
ADDRESSES: To get the service information identified in this AD,

SUPPLEMENTARY INFORMATION:
Discussion
What events have caused this AD? FAA received reports of damage to
the left and/or right MLG wire harness assemblies on Raytheon Model 390
airplanes. This resulted in various system failures/anomalies due to
erroneous air/ground status signals. Improper installation of Kit 390-
8103-0001 may have resulted in the damage to the squat switch wire
harness assemblies during normal extension and retraction operations. A
damaged wire harness and/or squat switch installation may affect
multiple systems on the airplane.
What is the potential impact if FAA took no action? Damage to the
wire harnesses could result in loss of pressurization, loss of
transponder responses to interrogations, and failure of other systems
utilizing air/ground status signals. This failure could lead to loss of
control of the airplane.
Has FAA taken any action to this point? 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, Premier 1 airplanes. This proposal was published in the
Federal Register as a notice of proposed rulemaking (NPRM) on October
7, 2004 (69 FR 60104). The NPRM proposed to require you to inspect the
routing and security of the left and right main landing gear (MLG)
squat switch wire harness installations for damage, repair any damage
or replace components, and reinstall the squat switch wire harness.
Comments
Was the public invited to comment? 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
What is FAA's final determination on this issue? 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.
Changes to 14 CFR Part 39--Effect on the AD
How does the revision to 14 CFR part 39 affect this AD? On July 10,
2002, the FAA published a new version of 14 CFR part 39 (67 FR 47997,
July 22, 2002), which governs the FAA's AD system. This regulation now
includes material that relates to altered products, special flight
permits, and alternative methods of compliance. This material
previously was included in each individual AD. Since this material is
included in 14 CFR part 39, we will not include it in future AD
actions.
Costs of Compliance
How many airplanes does this AD impact? We estimate that this AD
affects 98 airplanes in the U.S. registry.
What is the cost impact of this AD on owners/operators of the
affected airplanes? Raytheon Aircraft Company will provide warranty
credit as specified in the service information.
Authority for This Rulemaking
What authority does FAA have for issuing this rulemaking action?
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
[[Page 75224]]
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
Will this AD impact various entities? 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.
Will this AD involve a significant rule or regulatory action? 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
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-2004-19119; Directorate Identifier 2004-CE-26-AD'' in
your request.
