Amendment of Class E Airspace; La Porte, IN
This action corrects errors in the geographic coordinates of a final rule published in the Federal Register February 1, 2011, that amends Class E airspace in the La Porte, IN area.
Airworthiness Directives; The Boeing Company Model MD-90-30 Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require a detailed inspection to detect distress and existing repairs to the leading edge structure of the vertical stabilizer at the splice at Station Zfs=52.267; repetitive inspections for cracking in the front spar cap forward flanges of the vertical stabilizer, and either the aft flanges or side skins; repetitive inspections for loose and missing fasteners; and related investigative and corrective actions if necessary. This proposed AD was prompted by reports of cracked vertical stabilizer skin, a severed front spar cap, elongated fastener holes at the leading edge of the vertical stabilizer, and a cracked front spar web and front spar cap bolt holes in the vertical stabilizer. We are proposing this AD to detect and correct such cracking damage, which could result in the structure being unable to support limit load, and could lead to the loss of the vertical stabilizer.
Airworthiness Directives; The Boeing Company Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87), and MD-88 Airplanes

Airworthiness Directives; The Boeing Company Model 757-200, -200CB, and -300 Series Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require modifying the door latch fittings and witness mark placards of the off-wing escape slide systems; and for certain airplanes, replacing the bearings and lockbase retainer in the door latch assembly, relocating and adjusting of the sensor target and the sensor proximity switch, and testing to ensure positive door locking and corrective action if necessary. For certain airplanes, this proposed AD would also require installing a bumper assembly and placards. This proposed AD was prompted by reports of in-flight loss of the off-wing escape slide. We are proposing this AD to prevent in-flight loss of the off-wing escape slide, which could result in the unavailability of the escape slide during a time-critical evacuation. Additionally, the departed slide could cause damage to the fuselage, wing, flaps, or stabilizer, which could degrade flight control.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 190 Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. 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:
Airworthiness Directives; Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), Model CL-600-2D15 (Regional Jet Series 705), and Model CL-600-2D24 (Regional Jet Series 900) Airplanes

Airworthiness Directives; The Boeing Company Model 767-200, -300, -300F, and -400ER Series Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Model 767-200, -300, -300F, and -400ER series airplanes. The existing AD currently requires an inspection to determine if certain motor operated valve actuators for the fuel tanks are installed, and related investigative and corrective actions if necessary. This proposed AD would add airplanes and, for certain airplanes, require additional inspections to determine if certain motor operated valve actuators for the fuel tanks are installed, and related investigative and corrective actions if necessary. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent an ignition source inside the fuel tanks, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
