Special Conditions: Textron Aviation, Inc., Model C90A King Air; Installation of Electronic Engine Control System
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.
Proposed Amendment of Class D and E Airspace; Jacksonville, NC
This action proposes to amend Class D airspace associated with New River Marine Corps Air Station (MCAS), at Jacksonville, NC, by establishing controlled airspace at Albert J. Ellis Airport. This proposal would provide the controlled airspace required for the new air traffic control tower at Albert J. Ellis Airport for the safety and management of instrument flight rules (IFR) operations. This action also would update the geographic coordinates of New River MCAS in Class D and E airspace, replace the outdated term ``Airport/Facility Directory'' with the term ``Chart Supplement'', and make an editorial change to the airspace designation.
Amendment of Class E Airspace; Selinsgrove, PA
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.
Proposed Amendment of Class D Airspace and Class E Airspace; Pensacola, FL, and Proposed Establishment of Class E Airspace; Milton, FL
This action proposes to amend Class D airspace and Class E airspace extending upward from 700 feet above the surface at Choctaw Naval Outlying Field (NOLF), Milton, FL, by changing the city associated with the airport name in the above airspace classes and adjusting the geographic coordinates of the airport and the Santa Rosa TACAN navigation aid to match the FAA's aeronautical database. Additionally, Class E surface airspace would be established at Choctaw NOLF for the safety of aircraft landing and departing the airport when the air traffic control tower is closed. Also, an editorial change would be made to the Class D airspace legal description replacing ``Airport/Facility Directory'' with the term ``Chart Supplement''. This action would enhance the safety and management of instrument flight rules (IFR) operations at the airport.
Airworthiness Directives; The Boeing Company Airplanes
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.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, -500 series airplanes. This AD was prompted by a report of wire damage on a fuel boost pump power cable, and a separate report of a fuel tank explosion on a similarly equipped airplane. This AD requires the installation of new shielded wire bundles and convoluted liners within fuel tank conduits, and revision of the maintenance or inspection program, as applicable, to incorporate certain airworthiness limitations (AWLs). We are issuing this AD to address the unsafe condition on these products.
Aviation Safety Organization Changes
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.
