Department of Transportation April 9, 2019 – Federal Register Recent Federal Regulation Documents

We propose to adopt a new airworthiness directive (AD) for certain B/E Aerospace Fischer GmbH Common Seats 170/260 H160. This proposed AD was prompted by the discovery during testing that the energy absorber (EA) may not function as intended during emergency landing. This proposed AD would require removing and replacing the EA assemblies on the affected seats. We are proposing this AD to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for Pacific Aerospace Limited Model 750XL airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 non-compliant insulation lagging on the refrigerant hoses of the air-conditioning system. We are issuing this AD to require actions to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This proposed AD was prompted by reports of cracks within the ring gears of a slat geared rotary actuator (SGRA) resulting from a change in the raw material manufacturing process. This proposed AD would require replacement of affected parts with serviceable parts, as specified in an European Aviation Safety Agency (EASA) AD, which will be incorporated by reference. We are proposing this AD to address the unsafe condition on these products.

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.
