Proposed Modification of Control 1234L Offshore Airspace Area; AK
This action proposes to amend Control 1234L, Offshore Airspace Area in Alaska. Specifically, this action proposes to modify Control 1234L in the immediate vicinity of the Saint Paul Island Airport, AK, by lowering the airspace floor from 2,000 feet above ground level (AGL) to 700 AGL. Additionally, outside the vicinity of the airport this proposal lowers the airspace floor from 2,000 AGL to 1,200 feet AGL within a 73-mile radius of the St. Paul Island Airport. The FAA is proposing this action to provide additional controlled airspace for aircraft instrument operations (IFR) at the St. Paul Island Airport.
Airworthiness Directives; Airbus Model A319, A320, and A321 Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A319, A320, and A321 airplanes. This proposed AD would require a detailed inspection for cracks and marks on the carbon blades of the ram air turbine (RAT), and replacement of the RAT with a new or serviceable RAT if necessary. This proposed AD results from a report of three chord-wise cracks on the aft side of one carbon blade of a certain RAT. We are proposing this AD to detect and correct cracks and/or marks on the RAT carbon blades, which could result in reduced structural integrity of the carbon blade, and consequent loss of the RAT as a source of hydraulic and electrical power in an emergency.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-145XR Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain EMBRAER Model EMB-145XR airplanes. This proposed AD would require modification of the flap system interface wiring. This proposed AD results from a finding that the aural and visual warnings, which should be activated when the flaps are set to 22 degrees during takeoff, were not enabled during the manufacture of certain Model EMB- 145XR airplanes. We are proposing this AD to prevent overrunning the runway during takeoff.
Airworthiness Directives; McDonnell Douglas Model DC-9-31, DC-9-32, DC-9-32F, DC-9-33F, DC-9-34, and DC-9-34F Airplanes; and Model DC-9-40 and DC-9-50 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain transport category airplanes, identified above. This proposed AD would require installing a bonding jumper from the boost pump volute to the fuel tank structure, and related investigative/ corrective actions. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent point-contact arcing or filament heating in the fuel tank, which, in the event of a short or ground fault inside the fuel tank, could result in a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-145XR Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain EMBRAER Model EMB-145XR airplanes. This proposed AD would require replacement of certain segments of the passenger seat tracks with new, improved seat tracks. This proposed AD results from instances where the shear plungers of the passenger seat legs were not adequately fastened. We are proposing this AD to prevent inadequate fastening of the seat leg shear plungers, which could result in failure of the passenger seat tracks during emergency landing conditions and consequent injury to passengers.
Airworthiness Directives; Boeing Model 737-100, -200, and -200C Series Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Boeing Model 737 series airplanes. The existing AD currently requires inspection of the elevator tab inboard hinge support structure to detect fatigue cracking and corrective action if necessary. That AD also provides an optional terminating action. This proposed AD would add airplanes to the applicability and would require new repetitive inspections. For airplanes having elevators with laminated rear spars, this proposed AD would require repetitive inspections for interlaminar corrosion, delamination, or disbonding in the rear spar, repetitive inspections for cracking in the spar web, and repair including related investigative/corrective actions if necessary. For airplanes having elevators with solid rear spars, this proposed AD would require repetitive inspections for cracking in the spar web and repair including related investigative/corrective actions if necessary. This proposed AD results from reports of cracks in the elevator rear spar web at the tab hinge bracket locations. We are proposing this AD to detect and correct cracking, corrosion, interlaminar corrosion, delamination, and disbonding in the elevator rear spar, which may reduce elevator stiffness and lead to in-flight vibration. In-flight vibration may lead to elevator and horizontal stabilizer damage and reduced controllability of the airplane.

Point of Contact: Mr. Steve Kelley, Acting Manager, FAA Eastern Terminal Service, Airspace and Procedures, 1 Aviation Plaza, Jamaica, NY 11434-4809, (718) 553-4558.
Establishment of Area Navigation Instrument Flight Rules Terminal Transition Route (RITTR); T-210; Jacksonville, FL
This action corrects an error in the geographic coordinates of a waypoint (WP) listed in the description of route T-210 in a final rule published in the Federal Register on March 27, 2006 (71 FR 15027), Airspace Docket No. 05-ASO-10. This action also makes an editorial change to the order of the points listed in the route description.
Lightning Direct Effects Compliance
The Federal Aviation Administration (FAA) announces the availability of final policy on Lightning Direct Effects Compliance.
Airworthiness Directives; Gulfstream Model GIV-X and GV-SP Series Airplanes
The FAA is revising an existing airworthiness directive (AD), which applies to certain Gulfstream Model GIV-X and GV-SP series airplanes. That AD currently requires revising the Limitations section of the airplane flight manual (AFM) by incorporating new procedures to follow in the event that the cockpit displays go blank or malfunction. This AD allows for the use of alternative AFM revisions for a certain subset of the existing applicability. This AD results from a report that all four of the cockpit flight panel display units simultaneously went blank during flight. We are issuing this AD to ensure that the flightcrew is advised of the appropriate procedures to follow in the event that the cockpit displays go blank or malfunction, which could result in a reduction of the flightcrew's situational awareness and possible loss of control of the airplane.
Airworthiness Directives; Eurocopter France Model SA-360C, SA-365C, SA-365C1, and SA-365C2 Helicopters
This amendment adopts a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model SA-360C, SA-365C, SA-365C1, and SA-365C2 helicopters. This action requires inspecting the main gearbox (MGB) base plate for a crack and replacing the MGB if a crack is found. This amendment is prompted by the discovery of a crack in a MGB base plate. The actions specified in this AD are intended to detect a crack in a MGB base plate and prevent failure of one of the MGB attachment points to the frame, which could result in severe vibration and subsequent loss of control of the helicopter.
Airworthiness Directives; Fokker Model F.28 Mark 0100 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Fokker Model F.28 Mark 0100 airplanes. This AD requires reinforcing the fuselage at the emergency locator transmitter system's antenna area. This AD results from a report that certain structural provisions for an optional antenna are of insufficient strength. We are issuing this AD to prevent reduced structural integrity of the airplane.
Airworthiness Directives; Sicma Aero Seat (Formerly Farner); Cabin Attendant Seats Series 150 Type FN and Series 151 Type WN
The FAA is adopting a new airworthiness directive (AD) for Sicma Aero Seat (formerly Farner) cabin attendant seats series 150 type FN and series 151 type WN. This AD requires installing two protection fairings over the upper seat structure to cover the gap between the upper and lower seats and prevent any contact with the bottom seat folding mechanisms. This AD results from a child catching its fingers in the folding mechanism of the bottom of the attendant seat. We are issuing this AD to prevent injury resulting from contact with the bottom folding mechanism.
Airworthiness Directives; Boeing Model 767 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 767 airplanes. This AD requires performing a test of the bonding resistance between the engine fuel feed tube fitting and the front spar, applying sealant on a hex nut inside the dry bay, and performing any applicable corrective actions. This AD results from a report that the engine fuel feed tubes were found not electrically bonded to the front spar. We are issuing this AD to prevent an ignition source from entering the fuel tank during a lightning strike event, which could cause a fuel tank explosion.
