## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Pilatus Aircraft Ltd. (Pilatus) Models PC-12 and PC-12/45 airplanes. The proposed AD would require you to accomplish the following on the torque oil-pressure tubes and py pressure pipe: a one-time inspection for abrasion damage, distortion, and proper clearance; and if necessary, adjustment and replacement of these components. The proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Switzerland. The actions specified by the proposed AD are intended to correct abrasive damage from rubbing pipes and consequent loss of engine oil.
