Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to all AeroSpace Technologies of Australia Pty Ltd. (ASTA) Models N22B and N24A airplanes. This proposed AD would require you to visually inspect the ailerons for damage and replace if necessary; adjust the engine power levers aural warning microswitches; set flap extension and flap down operation limitations; and fabricate and install cockpit flap extension and flap down operation restriction placards. This proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Australia. The actions specified by this proposed AD are intended to prevent damage to the aileron due to airplane operation and pre-existing and undetected damage, which could result in failure of the aileron. Such failure could lead to reduced or loss of control of the airplane.
