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.

We estimate the following costs to do 

the inspection:

per airplane 

Total cost 

on U.S. 

operators

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 ...................................................

Remanufactured seat $320. 

New standard seat $765. 

New wide seat $885. 

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 

■ 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 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. FAA amends § 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: 

Actions Compliance Procedures 

(1) Inspect the rear seat back hinge area for cracking and 

elongation of the rear seat hinge bolt hole.

Within the next 25 hours time-in-service (TIS) after December 3, 2009

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

The heating capability of several [angle of 

attack] AOA transducer heating elements 

removed from in-service aircraft has been 

found to be below the minimum requirement. 

Also, it was discovered that a large number 

of AOA transducers repaired in an approved 

maintenance facility were not calibrated 

accurately. 

Inaccurate calibration of the AOA 

transducer and/or degraded AOA transducer 

heating elements can result in early or late 

activation of the stall warning, stick shaker 

and stick pusher by the Stall Protection 

Computer (SPC). 

* * * * * 

Inaccurate calibration of the AOA 

transducers and/or degraded AOA 

transducer heating elements could 

result in ineffective response to 

aerodynamic stall and reduced 

controllability of the airplane. This AD 

requires actions that are intended to 

address the unsafe condition described 

in the MCAI. 

DATES: This AD becomes effective 

November 13, 2009. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of November 13, 2009. 

We must receive comments on this 

AD by December 14, 2009.
