Pilatus Britten-Norman Limited BN-2A and BN2A Mk. III Series Airplanes

This amendment supersedes Airworthiness Directive (AD) 97-14- 01, which currently applies to all Pilatus Britten-Norman Limited (Pilatus Britten-Norman) BN-2A and BN2A Mk. III series airplanes. AD 97-14-01 requires repetitively inspecting the left-hand rudder bar assembly for cracks, measuring the slider tube unit wall thickness, and modifying the rudder bar assembly by installing a slider tube unit of improved design as a terminating action for the repetitive inspections. AD 97-14-01 resulted from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the United Kingdom. Reports of cracks being found on the right-hand rudder bar assembly and the inadvertent omission of requiring inspection of the rudder pedal beams prompted this action. This AD retains the requirements of AD 97-14-01 and requires inspections of the right-hand rudder bar assembly and each rudder pedal beam. The actions specified by this AD are intended to prevent failure of the pilot's and co-pilot's rudder bar assemblies, which could result in loss of control of the airplane during landing operations.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
