Full official abstract
The FAA is superseding Airworthiness Directive (AD) 2014-25-04 for 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 2014-25-04 required incorporating revised airworthiness limitations into the aircraft maintenance manual (AMM) for your FAA- approved maintenance program. This AD requires incorporating new airworthiness limitations and an eddy current inspection of each fuselage wing fitting if an earlier version of the service information was accomplished. This AD was prompted by a determination that the new life limits, revised airworthiness limitations, and new inspection procedures are necessary. The FAA is issuing this AD to address the unsafe condition on these products.
