RIN 2120-AA64


Airworthiness Directives; American Champion Aircraft Corporation 
7, 8, and 11 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; correction.

-----------------------------------------------------------------------

SUMMARY: This amendment clarifies information contained in 
Airworthiness Directive (AD) 2000-25-02, which concerns certain 
American Champion Aircraft Corporation (ACAC) 7, 8, and 11 series 
airplanes. This AD currently requires inspecting the front and rear 
wood spars for damage, including installing any as-needed inspection 
holes; and repairing or replacing any damaged wood spar. We incorrectly 
referenced the initial inspection compliance time of this AD as 
``whichever occurs later.'' The notice of proposed rulemaking (NPRM) 
contained the correct reference of ``whichever occurs first.'' This 
action revises the AD to reflect the correct reference in the 
compliance time. The actions specified by this AD are intended to 
detect and repair or replace damaged wood wing spars. Continued 
operation with such damage could progress to in-flight structural 
failure of the wing with consequent loss of control of the airplane.

EFFECTIVE DATE: The effective date of this AD is July 13, 2001.
    The Director of the Federal Register previously approved the 
incorporation by reference of American Champion Aircraft Corporation 
(ACAC), Service Letter 406, Revision A, dated May 6, 1998, as of 
January 19, 2001 (65 FR 78905, December 18, 2000).

ADDRESSES: You may get service information referenced in this AD from 
the American Champion Aircraft Corporation, P.O. Box 37, 32032 
Washington Avenue, Highway D, Rochester, Wisconsin 53167; internet 
address: www.amerchampionaircraft.com. You may examine this information

Federal Register, 800 North Capitol Street, NW., suite 700, Washington,

SUPPLEMENTARY INFORMATION:

Discussion

    Has FAA taken any action to this point? A review of the service 
history of ACAC 7, 8, and 11 series airplanes that incorporate wood 
wing spars caused FAA to issue AD 2000-25-02, Amendment 39-12036 (65 FR 
78905, December 18, 2000), which applies to certain American Champion 
Aircraft Corporation (ACAC) 7, 8, and 11 series airplanes. The AD 
currently requires inspecting the front and rear wood spars for damage, 
including installing any as-needed inspection holes; and repairing or 
replacing any damaged wood spar.
    What has happened since AD 2000-25-02 to initiate this action? The 
compliance time of the initial inspection of AD 2000-25-02 is written 
as at the first annual inspection that occurs 30 calendar days or more 
after the effective date of the AD or within 13 calendar months after 
the effective date of the AD, whichever occurs later. We incorrectly 
referenced this compliance time as ``whichever occurs later.'' The 
notice of proposed rulemaking (NPRM) (64 FR 29972, June 4, 1999) 
contained the correct reference of ``whichever occurs first.''
    What has FAA determined? Consequently, FAA has determined that AD 
2000-25-02 should be revised to ensure that the inspections and 
necessary replacements are accomplished in a timely manner.

Correction of Publication

    What is the intent of this action? This document clarifies the 
intent of the compliance time by changing the ``whichever occurs 
later'' reference of the initial compliance time of AD 2000-25-02 to 
``whichever occurs first.'' This document also adds the amendment to 
section 39.13 of the Federal Aviation Regulations (14 CFR 39.13).
    This action only clarifies the intent of AD 2000-25-02 and makes a 
change to reflect what was originally proposed. It has no adverse 
economic impact and imposes no additional burden on any person than 
would have been necessary to accomplish the AD. Therefore, FAA has 
determined that prior notice and opportunity for public comment are 
unnecessary.

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.


Sec. 39.13  [Amended]

    2. FAA amends Sec. 39.13 by removing Airworthiness Directive (AD) 
2000-25-02, Amendment 39-12036 (65 FR 78905, December 18, 2000), and by 
adding a new AD to read as follows:

2000-25-02 R1  American Champion Aircraft Company (ACAC): Amendment 
39-12255; Docket No. 98-CE-121-AD; Revises AD 2000-25-02, Amendment 
39-12036; which superseded AD 98-05-04, Amendment 39-10365 (63 FR 
10297, March 3, 1998).

    (a) What airplanes are affected by this AD? This AD applies to 
the following airplane models, all serial numbers, certificated in 
any category, that are equipped with wood wing spars:
    (1) Group 1 airplanes: ACAC Models 7AC, 7ACA, S7AC, 7BCM (L-
16A), 7CCM (L-16B), S7CCM, 7DC, S7DC, 7EC, S7EC, 7FC, 7JC, 11AC, 
S11AC, 11BC, S11BC, 11CC, and S11CC airplanes that have not been 
modified to incorporate an engine with greater than 90 horsepower.
    (2) Group 2 airplanes: ACAC Models 7ECA, 7GC, 7GCA, 7GCAA, 7GCB, 
7GCBA, 7GCBC, 7HC, 7KC, 7KCAB, 8GCBC, and 8KCAB airplanes; and any 
of the airplane models referenced in paragraph (a)(1) of this AD 
that have been modified to incorporate an engine with greater than 
90 horsepower.
    (b) Who must comply with this AD? Anyone who wishes to operate 
any of the above airplanes must comply with this AD.
    (c) What problem does this AD address? The actions specified by 
this AD are intended to detect and repair or replace damaged wood 
wing spars. Continued operation with such cracks and damage could 
progress to an in-flight structural failure of the wing with 
consequent loss of control of the airplane.
    (d) What actions must be accomplished on all Group 1 airplanes 
to address this problem? For any Group 1 airplane as referenced in 
paragraph (a)(1) of this AD, the following must be accomplished to 
address the problem:

or repaired in the area subject to the requirements of this AD. For 
airplanes that have been modified, altered, or repaired so that the

operator must request approval for an alternative method of 
compliance in accordance with paragraph (f) of this AD. The request 
should include an assessment of the effect of the modification, 
alteration, or repair on the unsafe condition addressed by this AD;
