Airworthiness Directive 03-27921
one-timeAirworthiness Directives; AeroSpace Technologies of Australia Pty Ltd. Models N22B and N24A Airplanes
What this AD requires
The FAA adopts a new airworthiness directive (AD) for all AeroSpace Technologies of Australia Pty Ltd. (ASTA) Models N22B and N24A airplanes. This AD requires 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 AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Australia. We are issuing this AD 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.
Which aircraft AD 03-27921 applies to
applicability derived from the AD summary — confirm the model/serial from the records
Whether AD 03-27921 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
