[Docket No. FAA-2007-28251; Directorate Identifier 2007-CE-049-AD; 
Amendment 39-15099; AD 2007-12-21]
RIN 2120-AA64


Airworthiness Directives; Hawker Beechcraft Corporation (Type 
Certificate No. A00010WI Previously Held by Raytheon Aircraft Company) 
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) to 
supersede AD 2006-26-08, which applies to all Hawker Beechcraft 
Corporation (HBC) Model 390 airplanes. AD 2006-26-08 currently requires 
you to repetitively inspect the hydraulic pump outlet tube on both 
engines and immediately replace the tube if damage is found. AD 2006-
26-08 also requires you to incorporate an airplane flight manual (AFM) 
change that limits operation of an engine with its associated firewall 
hydraulic shutoff valve closed. If an engine is operated with its 
firewall hydraulic shutoff valve closed, you must replace the hydraulic 
pump outlet tube. We issued AD 2006-26-08 as an interim action while we 
worked with the type certificate holder to develop a design change. HBC 
has

[[Page 33640]]

now developed kits that incorporate design changes for the hydraulic 
pump outlet tubes and dampener supports so this AD retains the actions 
of AD 2006-26-08 until the new modification kits required by this AD 
are installed. We continued to receive additional reports of failures 
of the hydraulic pump outlet tube. We are issuing this AD to prevent 
failure of the hydraulic pump outlet tube and consequent leaking of 
hydraulic fluid. Such leakage could result in a fire. There is also a 
risk of loss of hydraulic system functions including normal gear 
extensions, speed brakes, roll spoilers, lift dump, and normal brakes.

DATES: This AD becomes effective on June 20, 2007.
    On June 20, 2007, the Director of the Federal Register approved the 
incorporation by reference of Raytheon Aircraft Company Kit--Dampener 
Support Improvement, Drawing No. 390-5804 (Kit 390-5804-0001 Field 
Service Kit) and Raytheon Aircraft Company Kit--Hydraulic Pump Pressure 
Hose Installation No. 390-5805 (Kit 390-5805-0001 Field Service Kit), 
as referenced in Hawker Beechcraft Mandatory Service Bulletin 29-3800, 
Issued May 2007, as listed in this AD.
    As of February 2, 2006 (71 FR 5581, February 2, 2006), the Director 
of the Federal Register approved the incorporation by reference of 
Raytheon Mandatory Service Bulletin No. SB 29-3771, dated January 2006; 
and Raytheon Safety Communique No. 267, dated January 2006, as listed 
in this AD.
    We must receive any comments on this AD by August 20, 2007.

SUPPLEMENTARY INFORMATION:

Discussion

    Reports of left engine hydraulic tube assembly failures prompted us 
to issue AD 2006-02-51, Amendment 39-14459 (71 FR 5581, February 2, 
2006). AD 2006-02-51 required repetitive inspection of the hydraulic 
tube assembly, correction of the symptomatic clamp to hydraulic tube 
chafing on the left-hand nacelle, and reporting results to the FAA.
    After we issued AD 2006-02-51, we continued to receive additional 
reports of failures of the hydraulic pump outlet tube, including 
failures on the right engine on certain HBC Model 390 airplanes. This 
prompted us to supersede AD 2006-02-51 with AD 2006-26-08, Amendment 
39-14866 (71 FR 78051, December 28, 2006).
    AD 2006-26-08 currently requires you to repetitively inspect the 
hydraulic pump outlet tube on both engines and immediately replace the 
tube if damage is found. AD 2006-26-08 also requires you to incorporate 
an airplane flight manual (AFM) change that limits operation of an 
engine with its associated firewall hydraulic shutoff valve closed. If 
an engine is operated with its firewall hydraulic shutoff valve closed, 
you must replace the hydraulic pump outlet tube.
    We issued AD 2006-26-08 as an interim action while we worked with 
the type certificate holder to develop a design change. We continued to 
receive additional reports of failures of the hydraulic pump outlet 
tube.
    HBC has now developed kits that incorporate design changes for the 
hydraulic pump outlet tubes and dampener supports.
    Failure of the hydraulic pump outlet tubes, if not prevented, could 
cause flammable fluid leakage in the engine nacelle. Such leakage could 
result in a fire. There is also a risk of loss of hydraulic system 
functions including normal gear extensions, speed brakes, roll 
spoilers, lift dump, and normal brakes.

Relevant Service Information

    We reviewed Hawker Beechcraft Mandatory Service Bulletin No. 29-
3800, issued May 2007. The service information specifies the following 
actions:
    <bullet> Incorporating Kit No. 390-5804-0001, which replaces the 
pulse dampener brackets with stiffer brackets and a spacer on both 
engines; and
    <bullet> Incorporating Kit No. 390-5805-0001, which replaces the 
hydraulic pump outlet tubes with integral firesleeve hoses.
    Raytheon Mandatory Service Bulletin No. SB 29-3771, dated January 
2006; and Raytheon Safety Communique No. 267, dated January 2006, will 
be retained for this AD until both kits referenced above are 
incorporated.

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 retains 
the actions of AD 2006-26-08 and requires incorporating Kit No. 390-
5804-0001 and Kit No. 390-5805-0001. Upon incorporating the kits 
required by this AD, the repetitive inspections and replacement 
retained from AD 2006-26-08 are no longer necessary. The AFM limitation 
is still required.
    We continue to work with HBC in analyzing the design of the 
hydraulic system of the Model 390 airplanes. Based on this analysis, we 
may take future rulemaking action, which could eliminate the need for 
the current AFM limitation.
    In preparing this rule, we contacted type clubs and aircraft 
operators to get technical information and information on operational 
and economic impacts. We did not receive any information through these 
contacts. If received, we would have included a discussion of any 
information that may have influenced this action in the rulemaking 
docket.

FAA's Determination of the Effective Date

    Since an unsafe condition exists that requires the immediate 
adoption of this AD, 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

[[Page 33641]]

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-2007-28251; 
Directorate Identifier 2007-CE-049-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 and may amend the AD in light 
of those comments.
    We will post all comments we receive, without change, to <a href="http://dms.dot.gov">http://dms.dot.gov</a>, 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 <a href="http://dms.dot.gov">http://dms.dot.gov</a>; 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) 647-5227) is 
located at the street address stated in the ADDRESSES section. Comments 
will be available in the AD docket shortly after receipt.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the FAA amends 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]

2. The FAA amends Sec.  39.13 by removing Airworthiness Directive (AD) 
2006-26-08, Amendment 39-14866 (71 FR 78051, December 28, 2006), and by 
adding a new AD to read as follows:

2007-12-21 Hawker Beechcraft Corporation (Type Certificate No. 
A00010WI previously held by Raytheon Aircraft Company): Amendment 
39-15099; Docket No. FAA-2007-28251; Directorate Identifier 2007-CE-
049-AD.

Effective Date

    (a) This AD becomes effective on June 20, 2007.

Affected ADs

    (b) This AD supersedes AD 2006-26-08; Amendment 39-14866.

Applicability

    (c) This AD affects the following Model 390 airplanes that are 
certificated in any category:
    (1) Serial numbers RB-1 through RB-49 that have Field Service 
Kit 390-9100 installed; and
    (2) Serial numbers RB-50 through RB-209.
