Final rule; correction.
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.
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).
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 at the Federal Aviation Administration (FAA), Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 98-CE-121-AD, 901 Locust, Room 506, Kansas City, Missouri 64106; or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC.
Mr. William Rohder, Aerospace Engineer, FAA, Chicago Aircraft Certification Office, 2300 E. Devon Avenue, Des Plaines, Illinois 60018; telephone: (847) 294-7697; facsimile: (847) 294-7834.
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.
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.
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:
2. FAA amends § 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).

This AD applies to each airplane identified in paragraph (a) of this AD, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/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; and, if you have not eliminated the unsafe condition, specific actions you propose to address it.
