Airworthiness Directives; BAE SYSTEMS (Operations) Limited Model BAe 146 Airplanes and Model Avro 146-RJ Airplanes

The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to all Model BAe 146 airplanes and Model Avro 146-RJ airplanes. The original NPRM would have superseded an existing AD that currently requires revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate life limits for certain items and inspections to detect fatigue cracking in certain structures. The original NPRM proposed to require incorporating new and more restrictive life limits for certain items and for certain inspections to detect fatigue cracking in certain structures. The original NPRM resulted from issuance of a later revision to the airworthiness limitations. This new action revises the original NPRM by proposing to require revisions to the airworthiness limitations to include Critical Design Configuration Control Limitations for the fuel system. We are proposing this supplemental NPRM to ensure that fatigue cracking of certain structural elements is detected and corrected, and to prevent ignition sources in the fuel tanks; fatigue cracking of certain structural elements could adversely affect the structural integrity of these air

Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments

This rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPS) and associated Takeoff Minimums and Obstacle Departure procedures (ODPs) for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

Modification of Class D and Class E Airspace Areas; Roberts Field/Redmond Municipal Airport, Redmond, OR

This action proposes to modify the Class D and Class E airspace area designated as a surface area, modify the Class E airspace area designated as an extension to a Class D or Class E surface area, and modify the Class E airspace area extending upward from 700 feet above the surface at Roberts Field/Redmond Municipal Airport, Redmond, OR. This action would support the safety and management of instrument flight rules (IFR) operations at the airport.

Airworthiness Directives; Pilatus Aircraft Ltd. Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. This AD was prompted by a report that a solid-state relay (SSR) used in the left-hand (LH) windshield heating system may allow reverse current flow when in the OFF position. This AD requires modification of the airplane and replacement of the affected SSR with a serviceable part. The FAA is issuing this AD to address the unsafe condition on these products.
