14 CFR Part 39

[Docket No. FAA-2009-0745; Directorate Identifier 2009-CE-036-AD;

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:

PART 39--AIRWORTHINESS DIRECTIVES

0
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:
