14 CFR Part 39

[Docket No. FAA-2007-27860; Directorate Identifier 2007-CE-034-AD;
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.

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]

0
2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD)
82-07-04, Amendment 39-4355, and adding the following new AD:

2007-17-02 Allied Ag Cat Productions, Inc. (Type Certificate No.
1A16 formerly held by Schweizer Aircraft Corp.): Amendment 39-15160;
Docket No. FAA-2007-27860; Directorate Identifier 2007-CE-034-AD.

Effective Date

(a) This AD becomes effective on September 18, 2007.

Affected ADs

(b) This AD supersedes AD 82-07-04, Amendment 39-4355.

airplanes that are certificated in any category and have Gemini fuel
shut-off valve part number (P/N) 3/4-86-6-RT-6 (A3580-1) installed:
