Amendment of Multiple Restricted Areas; Vandenberg AFB, CA
This action makes minor adjustments to the boundary descriptions of restricted areas R-2516, R-2517, R-2534A and R-2534B; Vandenberg AFB, CA. The changes are necessary as a result of the FAA using updated digital data that defines maritime limits and other geophysical features used in the boundary descriptions. This requires minor changes to certain latitude/longitude points in the boundary descriptions of the above restricted areas to match the updated digital data.
Thirty Sixth RTCA SC-213 Enhanced Flight Vision Systems/Synthetic Vision Systems (EFVS/SVS) Joint Plenary With EUROCAE Working Group 70
The FAA is issuing this notice to advise the public of a meeting of the Thirty Sixth RTCA SC-213 Enhanced Flight Vision Systems/ Synthetic Vision Systems (EFVS/SVS) Joint Plenary with EUROCAE Working Group 70.
Fifty Third RTCA SC-224 Standards for Airport Security Access Control Systems Plenary
The FAA is issuing this notice to advise the public of a meeting of Fifty Third RTCA SC-224 Standards for Airport Security Access Control Systems Plenary.
Amendment of Class E Airspace; Seward, NE
This action modifies Class E airspace extending upward from 700 feet above the surface at Seward Municipal Airport, Seward, NE, to accommodate new standard instrument approach procedures for instrument flight rules (IFR) operations at the airport. This action is necessary due to the decommissioning of the Seward non directional radio beacon (NDB), and cancellation of the NDB approach procedure, and enhances the safety and management of IFR operations at the airport.
Airworthiness Directives; Fokker Services B.V. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Fokker Services B.V. Model F28 Mark 0100 airplanes. This proposed AD was prompted by a report that a jammed control cable prevented the full extension of the nose landing gear (LG). This proposed AD would require a general visual inspection of the LG handle teleflex cable conduit connector for the presence of a grease nipple, a maintenance records check of affected airplanes, and if necessary, a detailed inspection for corrosion and damage of the LG handle teleflex cable, replacement if found, and lubrication. This proposed AD would also require revising the maintenance or inspection program, as applicable. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Viking Air Limited Airplanes
We propose to adopt a new airworthiness directive (AD) for Viking Air Limited Models DHC-6-1, DHC-6-100, DHC-6-200, DHC-6-300, and DHC-6-400 airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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 aileron cable wear or fouling at the wing root rib, fuselage skin, and wing root rib fairlead, or fraying of the cable from the root rib fairlead. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc., Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), Model CL-600-2D15 (Regional Jet Series 705), Model CL-600-2D24 (Regional Jet Series 900), and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by a report indicating that a number of rubber bull gear (RBG) wheels installed in the horizontal stabilizer trim actuator (HSTA) were manufactured using an incorrect material specification. This AD requires replacement of the affected RBG wheels. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Saab AB, Saab Aeronautics (Formerly Known as Saab AB, Saab Aerosystems) Airplanes
We are adopting a new airworthiness directive (AD) for certain Saab AB, Saab Aeronautics Model SAAB 340B airplanes. This AD was prompted by reports of natural stall events in icing conditions, without prior stall warnings. This AD requires modifying the stall warning system, installing new stall warning computers, and activating the stall warning system. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters (Type Certificate Previously Held by Eurocopter France)
We are superseding Airworthiness Directive (AD) 2013-15-03 for Eurocopter France Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, AS350D, and AS350D1 helicopters. AD 2013-15-03 required inspecting the hydraulic pump drive pulley bearing (bearing) for leaks, rust, overheating, and condition. This new AD adds a requirement to grease the bearing and inspect for bronze particles in the grease, and changes the inspection and inspection intervals of the bearing until it is replaced with an improved bearing. This AD was prompted by additional reports of hydraulic pump drive belt failure caused by bearing seizures. The actions of this AD are intended to prevent an unsafe condition on these products.
