Full official abstract

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 you to perform a one-time inspection for abrasion damage, distortion, and proper clearance of the torque oil-pressure tubes and py pressure pipe, and if necessary, adjust and replace these components. This 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 correct abrasive damage from rubbing pipes and consequent loss of engine oil.
