AD 2000-02-31 65 FR 5428

This amendment adopts a new airworthiness directive (AD) that applies to certain Pilatus Aircraft Ltd. (Pilatus) Models PC-12 and PC- 12/45 airplanes. This AD requires replacing the stick pusher capstan and the stick pusher servo with parts of improved design. The AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Switzerland. The actions specified by this AD are intended to prevent improper operation of the stick pusher system caused by the existing design configuration, which could result in loss of control of the airplane during a stall.
