## Summary

The FAA is revising a notice of proposed rulemaking (NPRM) to supersede Airworthiness Directive (AD) 2014-25-04, which applies to all Pilatus Aircraft Ltd. (Pilatus) Model PC-6, PC-6-H1, PC-6-H2, PC-6/350, PC-6/350-H1, PC-6/350-H2, PC-6/A, PC-6/A-H1, PC-6/A-H2, PC-6/B-H2, PC- 6/B1-H2, PC-6/B2-H2, PC-6/B2-H4, PC-6/C-H2, and PC-6/C1-H2 airplanes. This action revises the NPRM by adding an eddy current inspection of each fuselage wing fitting if an earlier version of the service information was accomplished. The FAA is proposing this AD to address the unsafe condition on these products. Since these actions would impose an additional burden over those in the NPRM, the FAA is requesting comments on this SNPRM.
