Airworthiness Directives; Raytheon Aircraft Company, Model 390, 
Premier 1 Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Raytheon Aircraft Company (Raytheon), Model 390, Premier 1 
airplanes. This proposed AD would require you to install a kit to 
correct chafing conditions in the powerplant left hand and right hand 
engine installations. This proposed AD results from reports of 
inadequate left hand and right hand engine assembly cable, wire, and 
hose routing clearance. We are issuing this proposed AD to detect and 
correct chafing conditions in the engine installation, which could 
result in

leaking flammable fluids near an ignition source. This failure could 
lead to fire damage or loss of airplane control.

DATES: We must receive any comments on this proposed AD by August 1, 
2005.

Discussion

    What events have caused this proposed AD? The FAA has received 
reports of chafing conditions in the powerplant left hand and right 
hand engine assembly cable, wire, and hose routing clearance. The 
incidents of chafing have been reported on airplane serial numbers: RB-
20, RB-50, and RB-101.
    Investigation revealed that the areas of concern include control 
cables, wiring harnesses, fluid and drain hoses, and support structure. 
Further, FAA has determined that the cause of the unsafe condition 
relates to the design and quality control.
    Raytheon has developed a kit and service information to correct the 
chafing conditions.
    What is the potential impact if FAA took no action? The existence 
of chafing conditions in the engine installation could result in 
leaking flammable fluids near an ignition source. This failure could 
lead to fire damage or loss of airplane control.
    Is there service information that applies to this subject? Raytheon 
has issued Service Bulletin No. SB 71-3685, Issued May 2005.
    What are the provisions of this service information? The service 
bulletin includes procedures for correcting chafing conditions in the 
engine installation.

FAA's Determination and Requirements of This Proposed AD

    What has FAA decided? We have evaluated all pertinent information 
and identified an unsafe condition that is likely to exist or develop 
on other products of this same type design. For this reason, we are 
proposing AD action.
    What would this proposed AD require? This proposed AD would require 
you to incorporate the actions in the previously-referenced service 
bulletin.
    How does the revision to 14 CFR part 39 affect this proposed AD? On 
July 10, 2002, we published a new version of 14 CFR part 39 (67 FR 
47997, July 22, 2002), which governs 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 would this proposed AD impact? We estimate that 
this proposed AD affects 74 airplanes in the U.S. registry.
    What would be the cost impact of this proposed AD on owners/
operators of the affected airplanes? We estimate the following costs to 
do this proposed installation of the kit to correct chafing conditions 
in the engine installation:

----------------------------------------------------------------------------------------------------------------
                                                                                 Total cost per   Total cost on
                          Labor cost                              Parts cost        airplane      U.S. operators
----------------------------------------------------------------------------------------------------------------
16 work hours x $65 = $1,040.................................          $1,775           $2,815         $208,310
----------------------------------------------------------------------------------------------------------------


[[Page 31395]]

    The labor and part costs are covered by Raytheon Aircraft Company 
warranty.

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

    Would this proposed AD impact various entities? We have determined 
that this proposed AD would not have federalism implications under 
Executive Order 13132. This proposed AD would 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.
    Would this proposed AD involve a significant rule or regulatory 
action? For the reasons discussed above, I certify that this proposed 
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 proposed 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 
``AD Docket FAA-2005-21239; Directorate Identifier 2005-CE-27-AD'' in 
your request.
