Amendment 39-15451; AD 2008-07-10]

Airworthiness Directives; Hawker Beechcraft Corporation Models 
B200, B200GT, B300, and B300C 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) Models B200, B200GT, B300, 
and B300C airplanes. This AD requires you to fabricate and install a 
placard incorporating information that limits operation when there is 
known or forecast icing and requires you to replace a section of the 
pneumatic supply tube for the tail deice system with a new tube of a 
different material. This AD results from reports of collapsed tail 
deice boot pneumatic supply tubes. We are issuing this AD to prevent 
collapsed pneumatic supply tubes, which could result in failure of the 
tail deice boots to operate. This failure could lead to loss of control 
in icing conditions.

DATES: This AD becomes effective on April 10, 2008.
    On April 10, 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 June 6, 2008.

SUPPLEMENTARY INFORMATION: 

Discussion

    We received information of reports of collapsed pneumatic tubes, 
which supply pressure and vacuum to the horizontal stabilizer deice 
boots. With the introduction of an improved environmental control 
system, a section of the pneumatic deice tube located in the aft 
evaporator bay is subject to higher than normal temperature. This high 
heat in the aft evaporator bay may cause the tubing to soften and 
collapse undetected and permanently block flow to and from the deice 
boots.
    The pilot's operating handbook specifies to visually check deicing 
boots, where possible, for inflation and hold down function when ice 
protection equipment is required. However, the tail deice boots are not 
visible from the cockpit during the check.
    Since the collapse of the pneumatic deice supply tube is caused by 
the use of cabin heat, there is the possibility that the condition 
could occur after pre-flight verification of operation. Icing 
conditions and the use of cabin heat would be a normal operational 
mode.
    In February 2008, HBC issued a safety communique to inform flight 
crews of the potential for collapsed pneumatic supply tubes and 
recommended flight crews avoid flight into icing conditions.
    This condition, if not corrected, could result in failure of the 
tail deice boots to operate. This failure could lead to loss of control 
in icing conditions.

Relevant Service Information

    We reviewed Hawker Beechcraft Mandatory Service Bulletin SB 30-
3889, Issued: March 2008. The service information describes procedures 
for replacement of tail deice boot pneumatic supply tubes.

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 
you to fabricate and install a placard incorporating information that 
limits operation when there is known or forecast icing and requires you 
to replace a section of the pneumatic supply tube for the tail deice 
system with a new tube of a different material. The replacement of the 
tail deice boot pneumatic supply tubes is terminating action for the 
operation limitations in known or forecast icing.
    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

    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 this 
condition could result in failure of the tail deice boots to operate. 
This failure could lead to loss of control in icing conditions. 
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-2008-0392; 
Directorate Identifier 2008-CE-022-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 http://

[[Page 18707]]

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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    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 adding the following new 
airworthiness directive (AD):

2008-07-10 Hawker Beechcraft Corporation: Amendment 39-15451; Docket 
No. FAA-2008-0392; Directorate Identifier 2008-CE-022-AD.

Effective Date

    (a) This AD becomes effective on April 10, 2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to the following airplane models and serial 
numbers that are certificated in any category:

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