Compliance:     1. Within 50 hours time in service after 17 January 2008 or before 17 April 2008, whichever occurs first, unless already accomplished.

                2. Within 100 hours time in service after 17 January 2008, and thereafter at the intervals specified in Requirement 2, until both rudder bars are replaced with

             This Amendment becomes effective on 17 January 2008.
Background:  The manufacturer received a report of rudder bar distortion which occurred during intensive aerobatic operation.

             Amendment 1 was issued in response to a NZ CAA AD, which was prompted by the new Type Certificate holder for the HR 200 and R 2000 series aircraft, Alpha Aviation; correcting the applicable aircraft serial number range and including a means of identifying reinforced rudder bars.

   Amendment 2 is issued in response to a revision of the related NZ CAA AD, which expands aircraft applicability and reduces the inspection interval for unmodified HR 200 and R 2120 U aircraft.
