Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 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] 0 2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD) 2017-07-10, Amendment 39-18849 (82 FR 17542, April 12, 2017), and adding the following new AD: 2018-14-06 American Champion Aircraft Corp.: Amendment 39-19326; Docket No. FAA-2018-0003; Product Identifier 2017-CE-033-AD. (a) Effective Date This AD is effective August 17, 2018. (b) Affected ADs This AD replaces AD 2017-07-10, Amendment 39-18849 (82 FR 17542, April 12, 2017) (``AD 2017-07-10''). (c) Applicability This AD applies to any American Champion Aircraft Corp. Model 8KCAB airplane, certificated in any category, that either has: [[Page 32565]] (1) A serial number in the range of 1116-2012 through 1120-2012 or 1122-2012 through 1170-2017; or (2) Is equipped with part number 4-2142 exposed balance ailerons. (d) Subject Joint Aircraft System Component (JASC)/Air Transport Association (ATA) of America Code 57, Wings. (e) Unsafe Condition AD 2017-07-10 was prompted by a report of a cracked hinge support and cracked hinge ribs, which resulted in partial loss of control with the aileron binding against the cove. This AD incorporates a newly designed aileron hinge support reinforcement kit. We are issuing this AD to prevent failure of the aileron support structure, which may lead to excessive deflection, binding of the control surface, and potential loss of control. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Restrict Airplane Operation (1) Before further flight after April 12, 2017 (the effective date retained from AD 2017-07-10), fabricate a placard using at least \1/8\ inch letters with the words ``AEROBATIC FLIGHT PROHIBITED'' on it and install the placard on the instrument panel within the pilot's clear view. (2) This action may be performed by the owner/operator (pilot) holding at least a private pilot certificate and must be entered into the aircraft records showing compliance with this AD in accordance with 14 CFR 43.9(a)(1) through (4) and 14 CFR 91.417(a)(2)(v). The record must be maintained as required by 14 CFR 91.417, 121.380, or 135.439. (h) Inspection and Reinforcement (1) Within the next 10 hours time-in-service (TIS) after April 12, 2017 (the effective date retained from AD 2017-07-10), inspect the aileron hinge rib and support for cracks or other damage by following American Champion Aircraft Corporation Service Letter (SL) 442, dated February 16, 2017, or American Champion Aircraft Corp. Service Letter (SL) 442, Revision A, dated August 18, 2017 (ACAC SL No.442, Revision A). (2) If no cracks or other damage is found during the initial inspection required in paragraph (h)(1) of this AD, the placard prohibiting aerobatic flight required in paragraph (g)(1) of this AD can be removed. (3) Within 100 hours TIS from the initial inspection required in paragraph (h)(1) of this AD or within 10 hours TIS after August 17, 2018 (the effective date of this AD), whichever occurs later, and repetitively thereafter at intervals not to exceed 100 hours TIS, inspect the aileron hinge rib and support for cracks or other damage following ACAC SL No. 442, Revision A. (4) If cracks or other damage is found during any inspection required in paragraph (h)(1) or (3) of this AD, before further flight, replace any retained parts or structure that are cracked or damaged, and install the aileron hinge reinforcement kit by following American Champion Aircraft Corp. Service Letter 444, dated August 18, 2017 (ACAC SL No. 444). Unless already removed as specified in paragraph (h)(2) of this AD, after completing the corrective actions required by this paragraph, the placard prohibiting aerobatic flight required in paragraph (g)(1) of this AD can be removed. (5) Within 400 hours after the initial inspection required in paragraph (h)(1) of this AD, if not already done as required in paragraph (h)(4) of this AD, install the aileron hinge reinforcement kit following the procedures in ACAC SL No. 444. (6) After installation of the aileron hinge reinforcement kit required in paragraph (h)(4) or (5) of this AD, as applicable, insert page 4-1, Manual Revision B, of the Airworthiness Limitations section and page 5-9, Manual Revision B, of the Time and Maintenance Checks section, both dated October 3, 2017, from the American Champion Aircraft Corporation SM-601 8KCAB Service Manual, Reissue B, dated October 3, 2017, into the maintenance program (service manual). (7) Installing the aileron hinge reinforcement kit as required in paragraph (h)(4)or (h)(5) of this AD and the insertion of page 4-1, Manual Revision B, of the Airworthiness Limitations section and page 5-9, Manual Revision B, of the Time and Maintenance Checks section, both dated October 3, 2017, of the American Champion Aircraft Corporation SM-601 8KCAB Service Manual, Reissue B, dated October 3, 2017, into the maintenance program (e.g., service manual), as required in paragraph (h)(6) of this AD is terminating action to this AD. The revised Airworthiness Limitations section includes a 100- hour/annual inspection requirement for the aileron hinge supports. (i) Reporting Requirement Although ACAC SL No. 442, Revision A, and ACAC SL No. 444 specify submitting certain information to the manufacturer, this AD does not require that action. (j) Special Flight Permit No aerobatic flight permitted with a special flight permit.
