Airworthiness Directive · Amendment 39-10058 · Pilatus Britten-Norman Ltd. BN-2A and BN-2A Mk 111 Series Airplanes
Pilatus Britten-Norman Ltd. BN-2A and BN-2A Mk 111 Series Airplanes
Superseded. A later AD replaced this one: AD 2002-25-03. Comply with the one in force.
BN-2A and BN-2A Mk 111 Series airplanes (all serial numbers), certificated in any category.
This amendment supersedes Airworthiness Directive (AD) 75-24- 07 R1, which currently requires repetitively inspecting the left-hand (LH) rudder bar assembly for cracks and loose fasteners on certain Pilatus Britten-Norman Ltd. BN-2A and BN-2A Mk 111 series airplanes, and replacing any cracked part. The superseding action requires inspecting the LH rudder bar assembly and determining the wall thickness of the slider tube unit. This action also would require modifying the rudder bar assembly by replacing the LH slider tube with a new strengthened slider tube unit as terminating action for the repetitive inspections currently required by AD 75-24-07 R1. The development of a modification to the rudder bar assembly, which terminates the repetitive inspections required by AD 75-24-07 R1, prompted this AD. The actions specified by this AD are intended to prevent failure of the pilot's rudder bar assembly, 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.
