ACTION: Notice of Proposed Rulemaking
(NPRM).
SUMMARY: We propose to adopt 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 proposed AD would 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. This proposed AD
results from an occurrence of the rear
seat hinge area failing in flight. We are
proposing 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: We must receive comments on
this proposed AD by September 28,
2009.

ADDRESSES
Discussion
We received information that during a
training flight on an American
Champion Aircraft Corp. Model 8KCAB
airplane the rear seat hinge failed. While
performing spins, with the student pilot
in the front seat and the instructor pilot
in the rear seat, the rear seat hinge
broke, which resulted in the rear seat
back failing. The instructor pilot
partially fell into the baggage area. The
student and the instructor were able to
recover from the spins and landed safely
at the airport.
The Models 7GCAA, 7GCBC, 7KCAB,
and 8GCBC airplanes incorporate the
same or similar seat configuration.
This condition, if not corrected, 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.
Relevant Service Information
We have reviewed American
Champion Aircraft Corp. Service Letter
No. 431, dated July 20, 2009.
The service information describes
procedures for inspecting the rear seat
hinge areas for cracking and excessive
elongation of the rear seat hinge bolt
and, if cracking or excessive elongation
is found, replacing the rear seat frame.
FAA’s Determination and Requirements
of the Proposed AD
We are proposing this AD because we
evaluated all information and
determined the unsafe condition
described previously is likely to exist or
develop on other products of the same
type design. This proposed AD would
require inspecting 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, replacing the rear
seat frame.
Costs of Compliance
We estimate that this proposed AD
would affect 2,000 airplanes in the U.S.
registry.
We estimate the following costs to do
the proposed inspection:
Labor cost
Parts cost
Total cost per
airplane
Total cost on
U.S. operators
.5 work-hour × $80 per hour = $40 ...........................................................
Not applicable ..................................
$40
$80,000
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 × $80 per hour = $120 ..............
Remanufactured seat $200, New standard
seat $645, New wide seat $765.

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 rulemaking
action.

Regulatory Findings
We have determined that this
proposed AD would not have federalism
implications under Executive Order
13132. This proposed AD would 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 the proposed regulation:
E:\FR\FM\13AUP1.SGM
13AUP1
Federal Register / Vol. 74, No. 155 / Thursday, August 13, 2009 / Proposed Rules
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 regulatory evaluation
of the estimated costs to comply with
this proposed AD and placed it in the
AD docket.

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
rulemaking action.
Regulatory Findings
We have determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 the proposed
regulation:
[[Page 40783]]
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 regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket that contains the proposed AD, the
regulatory evaluation, any comments received, and other information on
the Internet at https://www.regulations.gov; or in person at the Docket
Management Facility between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. The Docket Office (telephone (800) 647-5527)
is located at the street address stated in the ADDRESSES section.
Comments will be available in the AD docket shortly after receipt.

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
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. The FAA amends Sec. 39.13 by adding the following new AD:
American Champion Aircraft Corp.: Docket No. FAA-2009-0745;
Directorate Identifier 2009-CE-036-AD.
Comments Due Date
(a) We must receive comments on this airworthiness directive
(AD) action by September 28, 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 proposing 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:
