Airworthiness Directives; American Champion Aircraft Corp.
Document Number: 2018-14686
Type: Rule
Date: 2018-07-13
Agency: Federal Aviation Administration, Department of Transportation
We are superseding Airworthiness Directive (AD) (AD) 2017-07- 10 for certain American Champion Aircraft Corp. (ACAC) Model 8KCAB airplanes. AD 2017-07-10 required fabrication and installation of a placard to prohibit aerobatic flight, inspection of the aileron hinge rib and support, and a reporting requirement of the inspection results to the FAA. This AD requires repetitive inspections of the aileron hinge support, installation of the aileron hinge support reinforcement kit, and incorporation of revised pages into the service manual. This AD 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. We are issuing this AD to address the unsafe condition on these products.
