CASA has determined that these ADs may be applicable to recently registered Australian aircraft. This Directive is issued to ensure all State of Design ADs are complied with. This amendment corrects an error in the title of AD 84-099-028(b) R1 (Main Gearboxes) and adds AD 84-084-027(b) R1 (Tail Rotor Pitch Control Rod) and AD F-2004-198 (Tail Rotor Main Gear Box). The original issue of this AD became effective 23 November 2006. David Punshon Delegate of the Civil Aviation Safety Authority 20 July 2007
