New AD (18-14-06) further addresses maintenance for the American Champion 8KCAB:
The original AD 17-07-10 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.” according to the superseding AD 18-14-06.
On January 11, 2018 the NPRM proposed to supersede AD 17-07-10, saying:
“Since AD 17-07-10 was issued, ACAC redesigned the aileron hinge supports with a reinforcement kit to strengthen the supports and prevent future damage from developing. This proposed AD would require repetitive inspections of the aileron hinge support, installation of the aileron hinge support reinforcement kit, and incorporation of revised pages into the service manual. We are proposing this AD to address the unsafe condition on these products.”
