Federal Aviation Administration March 5, 2018 – Federal Register Recent Federal Regulation Documents

These special conditions are issued for the Textron Aviation, Inc., model C90A King Air airplane. This airplane as modified by Nextant Aerospace will have a novel or unusual design feature associated with installation of an engine that includes an electronic engine control system. 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.

This action amends Class E airspace extending upward from 700 feet above the surface in Selinsgrove, PA. A new area navigation (RNAV) global positioning system (GPS) standard instrument approach procedure has been developed at Penn Valley Airport, requiring airspace reconfiguration at the airport. This action enhances the safety and airspace management of instrument flight rules (IFR) operations at the airport. This action also updates the geographic coordinates of the airport.

We propose to supersede Airworthiness Directive (AD) 2016-18- 01, which applies to certain The Boeing Company Model 737-600, -700, - 700C, -800, -900, and -900ER series airplanes. AD 2016-18-01 requires repetitive lubrication of the forward and aft trunnion pin assemblies of the right and left main landing gears (MLGs); repetitive inspection of these assemblies for corrosion and chrome damage, and related investigative and corrective actions, if necessary; and installation of new or modified trunnion pin assembly components, which terminates the repetitive lubrication and repetitive inspections. Since we issued AD 2016-18-01, we have determined that rotable parts were not addressed in that AD and that all airplanes of the affected models, excluding those with a certain configuration, should be inspected to determine if affected MLG trunnion pin assemblies are installed. This proposed AD would therefore add airplanes to the applicability. We are proposing this AD to address the unsafe condition on these products.

The FAA Aircraft Certification Service (AIR) and Flight Standards Service (AFS) have reorganized to align with functional organization design concepts. The AIR reorganization included eliminating product directorates and restructuring and re-designating field offices. The AFS reorganization included eliminating geographic regions, realigning headquarters organizations, and restructuring field offices. Currently, various rules in the Code of Federal Regulations refer to specific AIR and AFS offices that are obsolete after the reorganizations. This rule replaces specific references with generic references not dependent on any particular office structure. This rule does not impose any new obligations and is only intended to eliminate any confusion about with whom regulated entities and other persons should interact when complying with these various rules in the future.
