Amendment of Class B Airspace; Washington Tri-Area, DC
This action amends the description of Area D of the Washington Tri-Area Class B airspace area to include exclusion of restricted area R-4001C from the Class B airspace when the restricted area is active. The remainder of the Class B description is not affected by this change.
Modification, Revocation, and Establishment of Multiple Air Traffic Service (ATS) Routes; North Central and Northeast United States
This action amends, removes, and establishes multiple jet routes, high altitude and low altitude Area Navigation (RNAV) routes (Q- and T-routes), and VHF Omnidirectional Range (VOR) Federal airways in the north central and northeast United States (U.S.) to reflect and accommodate route changes being made in Canadian airspace as part of Canada's Winsor-Toronto-Montreal (WTM) airspace redesign project. This action also amends or removes ATS routes with minimal or no use. This action also corrects a publishing error in the NPRM regulatory text for Q-71, reverses the order of points published for RNAV route Q-844, changes an airway point in RNAV route Q-937, refines the geographic latitude/longitude position information for one waypoint (CLNTN), and corrects the state and country identifiers for three waypoints (KARIT, ATENE, and REVEN).
Airworthiness Directives; Airbus Airplanes
We are superseding Airworthiness Directive (AD) 2004-03-19, which applies to certain Airbus Model A320-111, -211 and -231 series airplanes. AD 2004-03-19 required repetitive inspections for cracking in the transition and pick-up angles in the lower part of the center fuselage area, and corrective action if necessary. AD 2004-03-19 also provided for an optional terminating modification for the repetitive inspection requirements. This new AD requires accomplishing the modification by installing washers between the transition pick-up angle and the pin nuts, and doing related investigative and corrective actions if necessary. This new AD also adds airplanes to the applicability of AD 2004-03-19. This AD was prompted by a determination that the optional terminating modification must be required in order to address the unsafe condition. We are issuing this AD to prevent fatigue cracking in the transition and pick-up angles of the lower part of the center fuselage, which could result in reduced structural integrity of the wing-fuselage support and fuselage pressure vessel.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-8 and 747-8F series airplanes. This AD was prompted by an analysis by the manufacturer, which revealed that certain fuse pins for the strut-to-wing attachment of the outboard aft upper spar are susceptible to migration in the event of a failed fuse pin through bolt. This AD requires replacing the fuse pins for the strut-to-wing attachment of the outboard aft upper spar with new fuse pins, and replacing the access cover assemblies with new access cover assemblies. We are issuing this AD to prevent migration of these fuse pins, which could result in the complete disconnect and loss of the strut-to-wing attachment load path for the outboard aft upper spar. The complete loss of an outboard aft upper spar strut-to-wing attachment load path could result in divergent flutter in certain parts of the flight envelope, which could result in loss of control of the airplane.
