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 (Raytheon), Model 390, Premier 1 airplanes.
For certain airplanes, this AD requires you (unless already done) to
replace the plastic cover over the air conditioning motor module with a
metallic cover and modify the air conditioning compressor motor module
electromagnetic interference-radio frequency interference (EMI-RFI)
filter located under the cover and reidentify the module part number.
For all airplanes, the AD limits future installations of the cover for
the air conditioner and the air conditioning compressor motor module.
This AD results from reports that the plastic cover over the air
conditioning motor module was found melted or burned and that the
overheating of the EMI-RFI filter assembly located under the cover
caused this damage. We are issuing this AD to prevent the melting or
burning of the plastic cover. The burning of the plastic cover could
result in a fire.
DATES: This AD becomes effective on January 23, 2006.
As of January 23, 2006, the Director of the Federal Register
approved the incorporation by reference of certain publications listed
in the regulation.

SUPPLEMENTARY INFORMATION:
Discussion
What events have caused this AD? The FAA has received reports that
the plastic cover over the air conditioning motor module for certain
Raytheon Aircraft Company (Raytheon), Model 390, Premier 1 airplanes
was found melted or burned. The overheating of the electromagnetic
interference-radio frequency interference (EMI-RFI) filter assembly
located under the plastic cover caused this damage.
Raytheon has developed two partial fixes that together remedy the
problem. In February 2005, Raytheon implemented a partial fix to the
problem with a service bulletin for the replacement of the plastic
cover with a manufactured or a field fabricated metal cover. Raytheon,
in June 2005, issued a service bulletin for the modification of the
EMI-RFI filter assembly.
What is the potential impact if FAA took no action? The burning of
the plastic cover could result in a fire.
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 Model 390, Premier 1
airplanes. This proposal was published in the Federal Register as a
notice of proposed rulemaking (NPRM) on August 23, 2005 (70 FR 49217).
The NPRM proposed for certain airplanes to require you (unless already
done) to replace the plastic cover over the air conditioning motor
module with a metallic cover and modify the air conditioning compressor
motor module electromagnetic interference-radio frequency interference
(EMI-RFI) filter located under the cover and reidentify the module part
number. For all airplanes, the NPRM proposed to limit future
installations of the cover for the air conditioner and the air
conditioning compressor motor module.
Comments
Was the public invited to comment? We provided the public the
opportunity to participate in developing this AD. The following
presents the one comment received on the proposal and FAA's response to
the comment:
Comment Issue: Include Parts Manufacture Approval (PMA) Parts Approved
by Identicality in the Replacement Parts
What is the commenter's concern? The commenter, the Modification
and Replacement Parts Association (MARPA), states:
``The proposed action requires replacing a plastic EMI-RFI filter
cover with a metallic cover P/N 390-555015-0001. The problem with
requiring the installation of a specific part number to the exclusion
of all other part numbers is that such a requirement conflicts with 14
CFR 21.303 (PMA).''
The MARPA requests that the final action include the phrase ``or
other FAA-approved equivalent part'' after the part number.
What is FAA's response to the concern? We agree with the MARPA. The
FAA will add the phrase ``or FAA-approved equivalent part number'', and
add language to cover the PMA replacement parts.
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 the
changes discussed above and minor editorial corrections. We have
determined that these changes and 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.
Docket Information
Where can I go to view the docket information? You may view the AD
docket that contains information relating to this subject in person at
the DMS Docket Offices between 9 a.m. and 5 p.m. (eastern time), Monday
through Friday, except Federal holidays. The Docket Office (telephone

ADDRESSES. You may also view the AD docket on the Internet at http://dms.dot.gov
.
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 100 airplanes in the U.S. registry.
What is the cost impact of this AD on owners/operators of the
affected airplanes? We estimate the following costs to do the
replacement of the plastic cover with a new manufactured metallic cover
(P/N 390-555015-0001 or FAA-approved equivalent part number) that you
buy:
----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on
Labor cost Parts cost airplane U.S. operators
----------------------------------------------------------------------------------------------------------------
1 work hour x $65 = $65......................................... $600 $665 $66,500
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do the field fabrication of the
metallic cover (P/N 390-555015-0001 or FAA-approved equivalent part
number) if you choose not to buy a new metallic cover and the labor for
the replacement of the plastic cover:

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 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
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-2005-20712; Directorate Identifier 2005-CE-15-AD'' in your
