Airworthiness Directives; The Boeing Company

We are revising an earlier proposed airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, - 900, and -900ER series airplanes. That NPRM proposed to require, for certain airplanes, installing two warning level indicator lights on each of the P1-3 and P3-1 instrument panels in the flight compartment. That NPRM also proposed to require revising the airplane flight manual to remove certain requirements of previous AD actions, and to advise the flightcrew of the following changes: revised non-normal procedures to use when a cabin altitude warning or rapid depressurization occurs, and revised cabin pressurization procedures for normal operations. That NPRM was prompted by a design change in the cabin altitude warning system that would address the identified unsafe condition. This action revises that NPRM by adding airplanes to the applicability; adding airplanes to the installation requirement, including, for certain airplanes, replacing the existing P5-16 and P5-10 panels; and, for certain airplanes, replacing the basic P5-16 panel with a high altitude landing P5-16 panel. We are proposing this supplemental NPRM to prevent failure of the flightcre

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.
