Amendment 39-15217; AD 2007-20-07]

Airworthiness Directives; Hawker Beechcraft Corporation (Type
Certificate No. A00010WI Previously Held by Raytheon Aircraft Company)
Model 390 Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Hawker Beechcraft Corporation Model 390 airplanes. This AD requires you
to inspect the starter-generator to determine the serial number (S/N)
and suffix letter, which indicates if the part is improperly shimmed.
This AD also requires you to replace any improperly shimmed starter-
generator with a properly shimmed starter-generator. This AD results
from reports of a manufacturing error where certain starter-generators
may have been improperly shimmed. We are issuing this AD to detect and
correct improperly shimmed starter-generators, which could result in
premature starter-generator failure. This failure could lead to
increased chances of dual starter-generator failure on the same flight.
DATES: This AD becomes effective on November 7, 2007.
On November 7, 2007, the Director of the Federal Register approved
the incorporation by reference of certain publications listed in this
AD.

SUPPLEMENTARY INFORMATION:
Discussion
On June 5, 2007, we issued a proposal to amend part 39 of the
Federal Aviation Regulations (14 CFR part 39) to include an AD that
would apply to certain Hawker Beechcraft Corporation Model 390
airplanes. This proposal was published in the Federal Register as a
notice of proposed rulemaking (NPRM) on June 12, 2007 (72 FR 32230).
The NPRM proposed to require you to inspect the starter-generator to
determine the S/N and suffix letter, which indicates if the part is
improperly shimmed. The NPRM also proposed to require you to replace
any improperly shimmed starter-generator with a properly shimmed
starter-generator.
Comments
We provided the public the opportunity to participate in developing
this AD. The following presents the comments received on the proposal
and FAA's response to each comment:
Comment Issue No. 1: Change the Term ``Defective'' in the AD
A representative of Hawker Beechcraft states that the term
``defective,'' as used in the NPRM, is not technically correct. The
starter-generators affected by the AD are not defective. The problem
causing the starter-generators to fail is improper shimming due to
poorly written or missing assembly instructions. Not all units in the
suspect range may be over-shimmed.
Hawker Beechcraft requests the term ``defective'' be changed
throughout the AD to describe the affected starter-generators more
accurately.
We concur with the commenter. We will change the term ``defective''
to ``improperly shimmed'' throughout the final rule AD action based on
this comment.
Comment Issue No. 2: Change the Term ``New Design'' in the AD
A representative of Hawker Beechcraft states that the term ``new
design,'' as used in the NPRM, is not accurate. The basic design of the
affected starter-generator did not change. The assembly instructions
were changed to ensure that future starter-generators are properly
shimmed.
Hawker Beechcraft requests the term ``new design'' be changed
throughout the AD to describe the replacement part more accurately.
We concur with the commenter. We will change the term ``new
design'' to ``properly shimmed'' throughout the final rule AD action
based on this comment.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed
except for the changes previously discussed and minor editorial
corrections. We have determined that these minor corrections:
Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
Costs of Compliance
We estimate that this AD affects 105 airplanes in the U.S.
registry.
We estimate the following costs to do the inspection:
----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on
Labor cost Parts cost airplane U.S. operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $80 per hour = $80.............. Not applicable.................. $80 $8,400
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary replacements
that will be required based on the results of the inspection. We have
no way of determining the number of airplanes that may need this
replacement:
------------------------------------------------------------------------
Total cost per
Labor cost Parts cost generator

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 AD.
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 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 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 ``Docket
No. FAA-2007-28068; Directorate Identifier 2007-CE-043-AD'' in your
request.
