## Abstract

This amendment adopts a new airworthiness directive (AD) that applies to all Aerospace Technologies of Australia Pty Ltd. (ASTA) Models N22B, N22S, and N24A airplanes. This AD requires repetitively inspecting the aft wing break connectors for arcing damage, deposits between contacts, and looseness of contacts; and removing deposits between contacts, tightening any loose contacts, and replacing any aft wing break connectors with arcing damage. This AD results from several reports of uncommanded flap extensions and displays of incorrect stall warning indications on the affected airplanes. The actions specified by this AD are intended to prevent contamination in the aft wing break connectors, which could result in uncommanded flap extensions and incorrect stall warning indications with consequent loss of airplane control.
