Airworthiness Directives; AeroSpace Technologies of Australia Pty Ltd Airplanes

The FAA adopts a new airworthiness directive (AD) for all AeroSpace Technologies of Australia Pty Ltd Model N22B, N22S, and N24A airplanes. This AD requires you to inspect the forward and aft face of the rear fuselage frame for cracks and to repair or modify accordingly. This AD is the result of mandatory continuing airworthiness information issued by the airworthiness authority for Australia. We are issuing this AD to detect and correct cracks in the rear fuselage frame, which could result in failure of the fuselage rear bulkhead and consequent loss of structural integrity.
