## Summary

This document proposes to revise an earlier proposed airworthiness directive (AD) that would apply to all Pilatus Aircraft Ltd. (Pilatus) Models PC-12 and PC-12/45 airplanes. The earlier NPRM would have required you to repetitively replace the nose landing gear (NLG) drag link right-hand part every 4,000 landings until an improved design NLG drag link right-hand part is installed. This earlier proposed AD would also have required you to install an improved design NLG drag link right-hand part as terminating action for the repetitive replacements. The earlier NPRM resulted from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Switzerland. The manufacturer has established a more restrictive factor that is a better approximation of the fleet usage. Since this action imposes an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on this additional action.
