Gross Combination Weight Rating (GCWR); Definition
FMCSA withdraws its August 27, 2012, direct final rule (DFR) amending the definition of ``gross combination weight rating'' (GCWR) in 49 CFR parts 383 and 390. The DFR would have taken effect on October 26, 2012. However, the Agency received several adverse comments in response to the DFR and will, therefore develop a notice of proposed rulemaking to request public comments on proposed changes to the GCWR definition.
Airworthiness Directives; Diamond Aircraft Industries GmbH Airplanes
We propose to adopt a new airworthiness directive (AD) for Diamond Aircraft Industries GmbH Models DA 42, DA 42 M-NG, and DA 42 NG 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 overextension of the main landing gear (MLG) shock absorber that could lead to the MLG jamming in the gear bay and result in damage to the aircraft or occupant injury. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
We propose to supersede an existing airworthiness directive (AD) that applies to certain The Boeing Company Model 707 airplanes, and Model 720 and 720B series airplanes. The existing 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. Since we issued that AD, we have determined through service experience that the inspection interval was too long. This proposed AD would reduce the repetitive inspection interval. We are proposing 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.
Airworthiness Directives; The Boeing Company Airplanes
We propose to supersede an existing airworthiness directive (AD) that applies to certain The Boeing Company Model 757-200 and - 200PF series airplanes. The existing AD currently requires modification of the nacelle strut and wing structure, and repair of any damage found during the modification. Since we issued that AD, a compliance time error involving the optional threshold formula was discovered, which could allow an airplane to exceed the acceptable compliance time for addressing the unsafe condition. This proposed AD would specify a maximum compliance time limit that overrides the optional threshold formula results. We are proposing this AD to prevent fatigue cracking in primary strut structure and consequent reduced structural integrity of the strut.
Establishment of Class E Airspace; La Belle, FL
This action establishes Class E Airspace at La Belle, FL, to accommodate the new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures at La Belle Municipal Airport. This action enhances the safety and airspace management of Instrument Flight Rules (IFR) operations within the National Airspace System.
Amendment of Area Navigation Route Q-1; CA
This action amends the legal description of area navigation (RNAV) route Q-1 by adding two waypoints along the route. In addition, the route description is amended to match a standardized format by adding the appropriate state name to the waypoints, the name and the state of the Point Reyes, CA, navigation aid, and listing of the points in the proper order.
