AD 2018-14-06 Airworthiness Directives; American Champion Aircraft Corp.
Makes named: american champion, champion. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to any American Champion Aircraft Corp. Model 8KCAB airplane, certificated in any category, that either has: (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.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
(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.
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.
Affected ADs
This AD replaces AD 2017-07-10, Amendment 39-18849 (82 FR 17542, April 12, 2017) (“AD 2017-07-10”).
