Federal Aviation Administration December 26, 2018 – Federal Register Recent Federal Regulation Documents

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 777 airplanes. This proposed AD was prompted by reports of uncommanded movements of the Captain's and First Officer's seats. This proposed AD would require an identification of the part number, and if applicable the serial number, of the Captain's and First Officer's seats, and do applicable on-condition actions for affected seats. This proposed AD would also require a one-time detailed inspection and repetitive checks of the horizontal movement system of the Captain's and First Officer's seats and applicable on-condition actions. This proposed AD would also provide an optional terminating action for the repetitive checks of the horizontal movement system. We are proposing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 767-200, -300, -300F, and -400ER series airplanes. This proposed AD was prompted by reports of uncommanded movements of the Captain's and First Officer's seats. This proposed AD would require an identification of the part number, and if applicable the serial number, of the Captain's and First Officer's seats, and applicable on-condition actions. This proposed AD would also require a one-time detailed inspection and repetitive checks of the horizontal movement system of the Captain's and First Officer's seats, and applicable on-condition actions. This proposed AD would also provide an optional terminating action for the repetitive checks of the horizontal movement system for certain airplanes. We are proposing this AD to address the unsafe condition on these products.

These special conditions are issued for the Airbus Model A330- 200, A330-200F, A330-300, and A330-900 series airplanes. These airplanes will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. This design feature is airplane electronic systems and networks that allow access, from aircraft internal sources (e.g., wireless devices, internet connectivity), to the airplane's previously isolated, internal, electronic components. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

We are superseding Airworthiness Directive (AD) 2016-25-19 for Airbus Helicopters (previously Eurocopter France) Model AS350B3 and EC130B4 helicopters. AD 2016-25-19 required inspecting the pilot's and co-pilot's throttle twist for proper operation. This new AD retains the requirements of AD 2016-25-19 and adds certain model helicopters to the applicability. The actions of this AD are intended to address an 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.

This action corrects a final rule published in the Federal Register of September 26, 2018, that established Class E airspace extending upward from 700 feet above the surface at Glen Ullin Regional Airport, Glen Ullin, ND. The state identifier ``WI'' was inadvertently, included in the header of the legal description instead of ``ND''.
