Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to Aerospace Technologies of Australia (ASTA) Nomad Models N22B, N22S, and N24A airplanes. The proposed action would require inspecting the flap and aileron control rod fork ends for water accumulation and corrosion inside the internally drilled holes, and replacing the control rod fork ends if there is visible corrosion or sealing the hole if no corrosion is found. Reports of water entering the internal holes of the flap and aileron control rod fork ends and causing corrosion prompted the proposed AD action. The actions specified by the proposed AD are intended to prevent corrosion and water accumulation in the flap and aileron control rod fork ends, which, if not detected and corrected, could cause loss of control of the flaps and aileron and possible loss of control of the airplane.
