Amendment 39-15160; AD 2007-17-02]
RIN 2120-AA64


Airworthiness Directives; Allied Ag Cat Productions, Inc. (Type 
Certificate No. 1A16 Formerly Held by Schweizer Aircraft Corp.) G-164 
Series Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) to 
supersede AD 82-07-04, which applies to certain Allied Ag Cat 
Productions, Inc. (Ag Cat) G-164 series airplanes. AD 82-07-04 
currently requires you to modify the fuel shut-off valve control by 
installing a new stop-plate. Since we issued AD 82-07-04, we have 
determined the need to add airplane models and serial numbers that were 
not previously included in the Applicability section. Consequently, 
this AD retains the actions of AD 82-07-04 and adds airplane models and 
serial numbers to the Applicability section. We are issuing this AD to 
prevent turning the fuel shut-off valve clockwise past the ``ON'' 
position stop which, if not corrected, could allow the fuel valve to be 
rotated to an unplacarded ``OFF'' position. This condition could lead 
to reduced fuel flow and consequent loss of engine power.

DATES: This AD becomes effective on September 18, 2007.
    On September 18, 2007, the Director of the Federal Register 
approved the incorporation by reference of certain publications listed 
in this AD.

SUPPLEMENTARY INFORMATION: 

Discussion

    On May 9, 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 Ag Cat G-164 series airplanes. This proposal was 
published in the Federal Register as a notice of proposed rulemaking 
(NPRM) on May 16, 2007 (72 FR 27489). The NPRM proposed to retain the 
actions of AD 82-07-04 and add airplane models and serial numbers to 
the applicability.

Comments

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

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 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.

Differences Between This AD and the Service Information

    This AD affects additional models and serial numbers airplanes 
compared to the list in the applicability section of the service 
information. The requirements of this AD take precedence over the 
provisions in the service information.

Costs of Compliance

    We estimate that this AD affects 1,400 airplanes in the U.S. 
registry, including those airplanes affected by AD 82-07-04.
    We estimate the following costs to do the modification:

----------------------------------------------------------------------------------------------------------------
                                                                                 Total cost per   Total cost on
                          Labor cost                              Parts cost        airplane      U.S. operators
----------------------------------------------------------------------------------------------------------------
2.5 work-hours x $80 per hour = $200.........................            $500             $700         $980,000
----------------------------------------------------------------------------------------------------------------

    We based our fleet cost estimate on all airplanes needing the 
modification. We have no way of knowing which airplanes already have 
modified the fuel shut-off control per AD 82-07-04. We also have no way 
of knowing how many airplanes have been retrofitted with the Gemini 
fuel shut-off valve part number 3/4-86-6-RT-6 (A3580-1) without 
incorporating AD 82-07-04.
    The estimated total cost on U.S. operators includes the cumulative 
costs associated with those airplanes affected by AD 82-07-04 and those 
airplanes being added in 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 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-2007-27860; Directorate Identifier 2007-CE-034-AD'' in your 
request.

Unsafe Condition

    (d) This AD results from our determination to add airplane 
models and serial numbers that were not previously included in the 
applicability. We are issuing this AD to prevent turning the fuel 
shut-off valve clockwise past the ``ON'' position which, if not 
corrected, could allow the fuel valve to be rotated to an 
unplacarded ``OFF'' position.
