Amendment 39-15707; AD 2008-22-11]

Airworthiness Directives; Hawker Beechcraft Corporation Model 390 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Hawker Beechcraft Corporation (HBC) Model 390 airplanes. This 
AD requires you to inspect hydraulic pump pressure output hose 
assemblies to determine if they are from the affected lots, inspect for 
hydraulic fluid leaks if the hose assemblies are from the affected 
lots, and replace all affected hose assemblies. This AD results from 
reports of hydraulic leaks from the hydraulic pump pressure output hose 
assemblies. We are issuing this AD to prevent leakage of hydraulic 
fluid from the pump output hose within the engine compartment, which 
could result in an in-flight fire.

DATES: This AD becomes effective on November 3, 2008.
    On November 3, 2008, the Director of the Federal Register approved 
the incorporation by reference of certain publications listed in this 
AD.
    We must receive any comments on this AD by December 23, 2008.

SUPPLEMENTARY INFORMATION: 

Discussion

    We received reports of hydraulic leaks from the hydraulic pump 
pressure output hose assemblies delivered to HBC. These assemblies were 
specially designed for use on the Model 390 airplanes and delivered 
only to HBC. Subsequent investigation revealed that a particular lot of 
hoses were thermally damaged during the manufacturing extrusion 
process. Parker's Stratoflex Products division discovered that some 
hose assemblies delivered to HBC for the Model 390 airplanes were in 
the thermally damaged lot of hoses.
    This condition, if not corrected, could result in leakage of 
hydraulic fluid from the pump output hose within the engine 
compartment, which could cause an in-flight fire.

Relevant Service Information

    We reviewed Hawker Beechcraft Mandatory Service Bulletin SB 29-
3897, dated August 2008. The service information describes procedures 
for inspection for suspect hydraulic pump pressure output hose 
assemblies and replacement of hose assemblies if necessary.

FAA's Determination and Requirements of This AD

    We are issuing this AD because we evaluated all the information and 
determined the unsafe condition described previously is likely to exist 
or develop on other products of the same type design. This AD requires 
inspection for suspect hydraulic pump pressure output hose assemblies 
and replacement of hose assemblies if necessary.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
leakage of hydraulic fluid from the pump output hose within the engine 
compartment could result in an in-flight fire. Therefore, we determined 
that notice and opportunity for public comment before issuing this AD 
are impracticable and that good cause exists for making this amendment 
effective in fewer than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and an opportunity for 
public comment. We invite you to send any written relevant data, views, 
or arguments regarding this AD. Send your comments to an address listed 
under the ADDRESSES section. Include the docket number ``FAA-2008-1127; 
Directorate Identifier 2008-CE-061-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of the AD. We will consider 
all comments received by the closing date

[[Page 63358]]

and may amend the AD in light of those comments.
    We will post all comments we receive, without change, to http://
www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive concerning this AD.

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 
rulemaking action.

Regulatory Findings

    We 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 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 regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

Examining the AD Docket

    You may examine the AD docket that contains the AD, the regulatory 
evaluation, any comments received, and other information on the 
Internet at http://www.regulations.gov; or in person at the Docket 
Management Facility between 9 a.m. and 5 p.m., Monday through Friday, 
except Federal holidays. The Docket Office (telephone (800) 647-5527) 
is located at the street address stated in the ADDRESSES section. 
Comments will be available in the AD docket shortly after receipt.
