Federal Aviation Administration September 18, 2014 – Federal Register Recent Federal Regulation Documents

We propose to adopt a new airworthiness directive (AD) for all Pilatus Aircraft Ltd. Models 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 that would supersede AD 2013-11-08. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as a need to incorporate new revisions into the aircraft maintenance manual or in the limitations document of the FAA-approved maintenance program. We are issuing this proposed AD to require actions to address the unsafe condition on these products.

This action modifies VOR Federal airway V-298 in the vicinity of Pasco, WA. The FAA is taking this action due to the Pasco, WA (PSC), VHF Omnidirectional Range (VOR)/Distance Measuring Equipment (DME) facility that provides navigation aid (NAVAID) guidance for a portion of V-298, being relocated. This action will ensure the safety and efficient management of aircraft operating within the National Airspace System.
