14 CFR Part 39

[Docket No. FAA-2007-28308; Directorate Identifier 2007-NM-016-AD; 
Amendment 39-15195; AD 2007-19-05]

Airworthiness Directives; Hawker Beechcraft Model 400, 400A, and 
400T Series Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Hawker Beechcraft Model 400, 400A, and 400T series airplanes. 
This AD requires modifying the attachment fasteners on the engine 
cowling panels. This AD results from several reports of loose 
attachment fasteners found on the engine cowling panels, and 
subsequently the panels either peeling back or separating from the 
airplane during flight. We are issuing this AD to prevent failure of 
the attachment fasteners on the engine cowling panels, which could 
result in separation of a panel from the airplane, and consequent 
damage to airplane structure. These conditions could adversely affect 
continued safe flight and landing of the airplane, or cause injury to 
people or damage to property on the ground.

DATES: This AD becomes effective October 23, 2007.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of October 23, 
2007.

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the AD docket on the Internet at http://dms.dot.gov 
or in person at the Docket Operations office between 9 a.m. and 5 p.m., 
Monday through Friday, except Federal holidays. The Docket Operations 
office (telephone (800) 647-5527) is located on the ground floor of the 
West Building at the DOT street address stated in the ADDRESSES 
section.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to certain Raytheon 
(Beech) Model 400, 400A, and 400T series airplanes. That NPRM was 
published in the Federal Register on May 29, 2007 (72 FR 29446). That 
NPRM proposed to require modifying the attachment fasteners on the 
engine cowling panels.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We received no comments on the NPRM or on the 
determination of the cost to the public.

Explanation of Change to Applicability

    We have revised the applicability of the existing AD to match the 
most recent type certificate data sheet for the affected models.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD with the 
change described previously. We have determined that this change will 
neither increase the economic burden on any operator nor increase the 
scope of the AD.

Costs of Compliance

    There are about 757 airplanes of the affected design in the 
worldwide fleet. This AD affects about 575 airplanes of U.S. registry. 
The required actions take about 10 work hours per airplane, at an 
average labor rate of $80 per work hour. Required parts cost about $400 
per airplane. Based on these figures, the estimated cost of this AD for 
U.S. operators is $690,000, or $1,200 per airplane.

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 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.
    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. See the ADDRESSES 
section for a location to examine the regulatory evaluation.

doing all the actions in accordance with the Accomplishment 
Instructions of Raytheon Service Bulletin SB 54-3788, dated December 
2006.

Alternative Methods of Compliance (AMOCs)

    (g)(1) The Manager, Wichita Aircraft Certification Office, FAA, 
has the authority to approve AMOCs for this AD, if requested in 
accordance with the procedures found in 14 CFR 39.19.
    (2) To request a different method of compliance or a different 
compliance time for this AD, follow the procedures in 14 CFR 39.19. 
Before using any approved AMOC on any airplane to which the AMOC
