Airworthiness Directives; American Champion Aircraft Corp. Models
7ECA, 7GCAA, 7GCBC, 7KCAB, 8KCAB, and 8GCBC Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for all
American Champion Aircraft Corp. Models 7ECA, 7GCAA, 7GCBC, 7KCAB,
8KCAB, and 8GCBC airplanes, manufactured prior to 1989 and equipped
with folding rear seat backs. This AD requires inspection of the rear
seat back hinge areas for cracking and excessive elongation of the rear
seat hinge bolt hole and, if cracking or excessive elongation is found,
replacement of the rear seat frame. We are issuing this AD to detect
and correct cracking of the rear seat back hinge area and excessive
elongation of the rear seat hinge bolt hole, either of which could
result in failure of the seat back. This failure could lead to a rear-
seated pilot or passenger inadvertently interfering with the control
stick while attempting to not roll to the rear of the airplane upon
seat back failure. Consequently, this failure could result in loss of
control.
DATES: This AD becomes effective on December 3, 2009.
On December 3, 2009, the Director of the Federal Register approved
the incorporation by reference of certain publications listed in this
AD.

SUPPLEMENTARY INFORMATION:
Discussion
On August 7, 2009, 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 all American Champion Aircraft Corp. Models 7ECA, 7GCAA,
7GCBC, 7KCAB, 8KCAB, and 8GCBC airplanes, manufactured prior to 1989
and equipped with folding rear seat backs. This proposal was published
in the Federal Register as a notice of proposed rulemaking (NPRM) on
August 13, 2009 (74 FR 40781). The NPRM proposed to require inspection
of the rear seat back hinge areas for cracking and excessive elongation
of the rear seat hinge bolt hole and, if cracking or excessive
elongation is found, replacement of the rear seat frame.
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.
Costs of Compliance
We estimate that this AD affects 2,000 airplanes in the U.S.
registry.
[[Page 55766]]
We estimate the following costs to do the inspection:
------------------------------------------------------------------------
Total cost Total cost
Labor cost Parts cost per on U.S.
airplane operators
------------------------------------------------------------------------
.5 work-hour x $80 per hour = Not applicable. $40 $80,000
$40.
------------------------------------------------------------------------
We estimate the following costs to do any necessary replacements
that would be required based on the results of the proposed inspection.
We have no way of determining the number of airplanes that may need
this replacement:
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Total cost per airplane
----------------------------------------------------------------------------------------------------------------
1.5 work-hours x $80 per hour = $120. Remanufactured seat Remanufactured seat $320.
$200. New standard seat $765.
New standard seat $645. New wide seat $885.
New wide seat $765.....
----------------------------------------------------------------------------------------------------------------
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-2009-0745; Directorate Identifier 2009-CE-036-AD'' in your
request.

Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the Federal Aviation Administration amends part 39 of the Federal
Aviation Regulations (14 CFR part 39) as follows:

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]

2. FAA amends Sec. 39.13 by adding the following new AD:
2009-22-02 American Champion Aircraft Corp.: Amendment 39-16053;
Docket No. FAA-2009-0745; Directorate Identifier 2009-CE-036-AD.
Effective Date
(a) This AD becomes effective on December 3, 2009.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Models 7ECA, 7GCAA, 7GCBC, 7KCAB, 8KCAB,
and 8GCBC airplanes, all serial numbers, that are:
(1) Manufactured prior to 1989;
(2) Equipped with folding rear seat backs; and
(3) Certificated in any category.
Unsafe Condition
(d) This AD results from an occurrence of the rear seat frame
failing in flight. We are issuing this AD to detect and correct
cracking of the rear seat back hinge area and excessive elongation
of the rear seat hinge bolt hole, which could result in failure of
the rear seat back. This failure could lead to a rear-seated pilot
or passenger inadvertently interfering with the control stick while
attempting to not roll to the rear of the airplane upon seat back
failure. Consequently, this failure could result in loss of control.
Compliance
(e) To address this problem, you must do the following, unless
already done:
