Federal Aviation Administration February 14, 2013 – Federal Register Recent Federal Regulation Documents

This action proposes to modify the Minneapolis, MN, Class B airspace area to contain large turbine-powered aircraft conducting published instrument procedures at the Minneapolis-St. Paul International Airport (MSP), MN, within Class B airspace. The FAA is proposing this action to ensure containment of aircraft being vectored to and conducting Simultaneous Instrument Landing System (SILS) approaches to parallel Runways 12L/R and 30L/R, aircraft being vectored to and conducting approaches to Runway 35, and aircraft being re- sequenced from approaches to Runway 35 to approaches to Runway 30L. This action would further support the FAA's national airspace redesign goal of optimizing terminal and en route airspace areas to enhance safety, improving the flow of air traffic, and reducing the potential for near midair collision in the terminal area.

This action proposes to establish five new RNAV routes in support of the Washington, DC, Optimization of Airspace and Procedures in a Metroplex (OAPM) project. The proposed routes would increase efficiency and allow easier transition into the high altitude structure for departures from the Washington, DC Metropolitan area airports.

We are superseding an existing airworthiness directive (AD) for certain The Boeing Company Model 707 airplanes, and Model 720 and 720B series airplanes. That AD currently requires replacing wiring for the fuel boost pumps and override pumps with new wiring, installing Teflon sleeving on the wiring, and doing associated actions; and doing repetitive inspections to detect damage of the wiring or evidence of a fuel leak. This new AD reduces the repetitive inspection interval. This AD was prompted by a determination that an inspection interval must be reduced. We are issuing this AD to detect and correct damaged wiring for the fuel boost pumps and override pumps, which could cause electrical arcing that could puncture the conduit containing the wire, and result in a fuel tank explosion or a fire adjacent to the fuel tank.
