EASA AD US-2018-14-06
Wings - Aileron Hinge Support - Inspection / Installation
Summary
Airworthiness Directive 2018-14-06 is a final rule issued by the FAA addressing certain American Champion Aircraft Corp. Model 8KCAB airplanes. It mandates repetitive inspections of the aileron hinge support, installation of a reinforcement kit, and updates to the service manual to prevent failure of the aileron support structure that could lead to loss of control.
What Changed
This AD supersedes AD 2017-07-10 by removing the previous reporting requirement and adding repetitive inspections of the aileron hinge support along with mandatory installation of the aileron hinge support reinforcement kit. It also requires incorporation of revised service manual pages to reflect these changes.
Why It Matters
This directive is critical for maintaining the structural integrity of the aileron hinge support on affected aircraft, preventing control surface binding and potential partial loss of control. Operators and maintenance personnel must comply to ensure continued airworthiness and flight safety, especially for aircraft used in aerobatic operations.
What To Do
Affected operators must perform repetitive inspections of the aileron hinge support starting August 17, 2018, install the reinforcement kit as required, and update their service manuals with the revised pages. Compliance with these actions is mandatory by the effective date to mitigate the unsafe condition.
