## Summary

The FAA is revising a notice of proposed rulemaking (NPRM) that would have applied to certain Pilatus Aircraft Ltd. (Pilatus) Model PC-12 airplanes. This action revises the NPRM by changing the applicability. The FAA is proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions would impose an additional burden over those in the NPRM for different airplanes, the FAA is requesting comments on this SNPRM.
