Abstract
The FAA proposes to supersede Airworthiness Directive (AD) 2021-11-08, 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. AD 2021-11-08 requires revising the airworthiness limitation section (ALS) of the existing aircraft maintenance manual (AMM) or instructions for continued airworthiness (ICA) to incorporate new airworthiness limitations and adding an additional eddy current inspection of the fuselage wing fittings and wing-to-fuselage fittings if the last inspection was performed using an earlier version of the material. Since the FAA issued AD 2021-11-08, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the ALS of the existing AMM or ICA for these airplanes. The FAA is proposing this AD to address the unsafe condition on these products.
