Applies to

This AD affects Models N22B, N22S, and N24A airplanes, all serial numbers including airplanes with float/amphibian configuration, that are certificated in any category.

The FAA's summary

The FAA is adopting a new airworthiness directive (AD) to supersede AD 2003-22-13, which applies to all AeroSpace Technologies of Australia Pty Ltd. (ASTA) Models N22B and N24A airplanes. AD 2003-22-13 currently 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 results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Australia. The FAA inadvertently omitted Model N22S airplanes from the applicability of AD 2003-22-13. Therefore, this AD retains the actions exactly as required in AD 2003-22-13 and adds Model N22S airplanes to the Applicability section. We are issuing this AD to prevent failure of the aileron due to undetected pre-existing aileron damage and airplane operation outside of the approved limits. Aileron failure could lead to reduced or loss of control of the airplane.

What it requires

Compliance

To address this problem, you must do the following:

Actions	Compliance	Procedures
(1) Visually inspect the left-hand and right-hand ailerons for damage (i.e., distortion, bending, impact marks). Repair or replace any damaged aileron found	(i) For Models N22B and N24A airplanes (airplanes previously affected by AD 2003-22-13): Inspect within the next 50 hours time-in-service (TIS) after December 23, 2003 (the effective date of AD 2003-22-13), unless already done	Following the applicable maintenance manual.
