AD 95-04-09 60 FR 12408

This amendment adopts a new airworthiness directive (AD) that applies to Pilatus Britten-Norman BN2A, BN2B, and BN2T Islander and BN2A Mk III Trislander series airplanes that are equipped with a nose wheel steering disconnect system with either a Modification NB/M/503 or Modification NB/M/733 nose undercarriage unit. This action requires repetitively inspecting the nose wheel steering drive ring for cracks, and replacing any cracked drive ring. A report of the rudder pedals jamming in the central position during takeoff on one of the affected airplanes prompted this action. The actions specified by this AD are intended to [[Page 12409]] prevent failure of the nose wheel steering system because of a cracked drive ring, which, if not detected and corrected, could result in the inability to move the rudder pedals.
