ACTION: Final rule. AGENCY: 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 startergenerator failure. This failure could lead to increased chances of dual startergenerator 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. ADDRESSES: For service information identified in this AD, contact Hawker Beechcraft Company, P.O. Box 85, Wichita, Kansas 67201–0085; telephone: (800) 429–5372 or (316) 676–3140.

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 startergenerators 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 startergenerator 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 airplane Labor cost Parts cost 1 work-hour × $80 per hour = $80 ............................................................ Not applicable .................................. ebenthall on PRODPC61 with RULES 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 Total cost on U.S. operators $80 $8,400 determining the number of airplanes that may need this replacement: Labor cost Parts cost Total cost per generator 5 work-hours × $80 per hour = $400 ................ $9,648 for new part; $6,593 for overhauled part. $10,048 for new part; $6,993 for overhauled part.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on March 16, 2007 (72 FR 12576). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: It has been revealed that the control surface balancing procedure in the Web and CD/DVD versions of the SAAB 2000 SRM (structural repair manual) Chapter 51–60–00, Control Surface Balancing Procedure is incorrect. The incorrect Calculation formula (page 1, 4 and 7) was incorporated in Revision 21 of the SRM dated April 01/05 and was distributed in 4 July 2005 on the CD/DVD issue Apr. 01/ 05. In the incorrect formula, an ‘‘×’’ (multiplication) has been replaced with a ‘‘+’’ (addition) when the data was converted in the system and if this formula is followed, you may receive a result outside of the allowed tolerance. Incorrect balance, outside the tolerance of the aileron control surface, may lead to vibrations that in [the] worst case can result in flutter. The hard copy of the manual, SAAB 2000 SRM, is correct. The CD/DVD dated Oct 01/05, marked ‘‘Reissue’’, includes a correct SAAB SRM revision 22. The corrective action includes identifying ailerons that have been balanced after July 4, 2005. If balanced incorrectly, they must be rebalanced. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received. Request To Withdraw the NPRM Saab points out that at the time European Aviation Safety Agency (EASA) issued Emergency Airworthiness Directive 2006–0053–E, dated February 22, 2006 (the MCAI), the hard copy of the structural repair manual (SRM) was correct but the Web and CD/DVD versions had an incorrect calculation formula. At that time, the FAA did not issue an emergency AD because there were only 3 of the affected airplanes operating in the U.S. and the E:\FR\FM\03OCR1.SGM 03OCR1

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.

ADDRESSES: For service information identified in this AD, contact

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
------------------------------------------------------------------------
5 work-hours x $80 per hour =     $9,648 for new      $10,048 for new
 $400.                             part; $6,593 for    part; $6,993 for

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.
