Establishment of Area Navigation Routes; Southwestern and South Central United States
This action establishes three area navigation (RNAV) routes over Southwestern and South Central United States in support of the High Altitude Redesign (HAR) program. The FAA is taking this action to enhance safety and to improve the efficient use of the navigable airspace.
Airworthiness Directives; Boeing Model 727, 727C, 727-100, and 727-100C Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 727, 727C, 727-100, and 727-100C series airplanes. This proposed AD would require repetitive inspections for cracks in the body skin and bear strap at the upper and lower hinge cutouts of the mid-cabin galley doorway, along the upper fastener row of the stringer 14R lap splice, and in the doorstop fitting adjacent to the upper hinge cutout; and corrective action if necessary. This proposed AD also provides for optional terminating action for certain inspections. This proposed AD results from reports of skin and bear strap cracking at the upper and lower hinge cutout and along the upper fastener row of the stringer 14R lap splice, and cracking in the doorstop fitting adjacent to the upper hinge cutout. There are also reports of cracking on airplanes previously modified to prevent such cracking. We are proposing this AD to find and fix fatigue cracking of the fuselage, which could result in reduced structural integrity and consequent rapid decompression of the airplane.
Airworthiness Directives; Airbus Model A318-100 and A319-100 Series Airplanes, A320-111 Airplanes, A320-200 Series Airplanes, and A321-100 and A321-200 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A318-100 and A319-100 series airplanes, A320- 111 airplanes, A320-200 series airplanes, and A321-100 and A321-200 series airplanes. This proposed AD would require operators to review the airplane's maintenance records to determine the part numbers of the magnetic fuel level indicators (MFLI) of the fuel tank, and related investigative and corrective actions if necessary. This proposed AD results from several in-service incidents of wear and detachment of the top-stops from the MFLI. Such detachment allows the top-stop to move around the fuel tank, and the top-stop could come into contact or in close proximity with a gauging probe, resulting in compromise of the air gap between the probe and the structure and creating a potential ignition source. We are proposing this AD to prevent an ignition source in the fuel tank in the event of a lightning strike, which could result in a fire or explosion.
