Department of Transportation November 6, 2017 – Federal Register Recent Federal Regulation Documents

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.

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.

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.

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.

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.
