Sixteenth Meeting: NextGen Advisory Committee (NAC)
The FAA is issuing this notice to advise the public of the sixteenth NextGen Advisory Committee meeting.
Proposed Amendment of Air Traffic Service (ATS) Routes; Northeast United States
This action proposes to modify jet routes J-6, J-97, and J- 222, and VOR Federal airways V-196, and V-489, in the northeastern United States due to the planned decommissioning of the Plattsburgh, NY, VORTAC facility.
Airworthiness Directives; The Boeing Company Airplanes
We propose to supersede Airworthiness Directive (AD) 2012-12- 04, which applies to certain The Boeing Company Model 737-300, -400, and -500 series airplanes. AD 2012-12-04 currently requires repetitive external detailed inspections and nondestructive inspections to detect cracks in the fuselage skin along the chem-mill steps at stringers S-1 and S-2R, between station (STA) 400 and STA 460, and repair if necessary. Since we issued AD 2012-12-04, we have determined that, for certain airplanes, the skin pockets adjacent to the Air Traffic Control (ATC) antenna are susceptible to widespread fatigue damage. This proposed AD would require a preventive modification of the fuselage skin at crown stringers S-1 and S-2R. This proposed AD would reduce inspection thresholds and repetitive intervals for certain airplanes. We are proposing this AD to detect and correct fatigue cracking of the fuselage skin panels at the chem-mill steps, which could result in sudden fracture and failure of the fuselage skin panels, and consequent rapid decompression of the airplane.
