We are revising an earlier NPRM for the products listed above. This action revises the earlier NPRM by expanding the scope. 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; Airbus Model A300 B4-601, B4-603, B4-605R, B4-620, B4-622, B4-622R, F4-605R, F4-622R, and C4-605R Variant F Series Airplanes Equipped With Simmonds Precision Products, Inc., Fuel Quantity Indicating System Sensors and In-Tank Harnesses Installed in Accordance With Supplemental Type Certificate (STC) ST00092BO
We propose to adopt a new airworthiness directive (AD) for certain Airbus model series airplanes. This proposed AD would require revising the Airworthiness Limitations Section of the Instructions for Continuing Airworthiness to incorporate new fuel system limitations for airplanes modified in accordance with STC ST00092BO. This AD also requires performing a general visual inspection for tank unit separation and compensator separation of the: center, inner, outer fuel tanks, and trim fuel tanks of the tank units, and corrective actions if necessary. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent a potential of ignition sources inside fuel tanks, which in combination with flammable fuel vapors, could result in a fuel tank fire or explosion and consequent loss of the airplane.
Airworthiness Directives; Hawker Beechcraft Corporation Model BH.125 Series 600A Airplanes and Model HS.125 Series 700A Airplanes Modified in Accordance With Supplemental Type Certificate (STC) SA2271SW
We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Model BH.125 series 600A airplanes and Model HS.125 series 700A airplanes. This AD requires inspecting the wiring diagrams containing the cockpit blowers and comparing with the current airplane configuration, and reworking the wiring if necessary. This AD results from a report indicating that a blower motor of the cockpit ventilation and avionics cooling system seized up and gave off smoke. We are issuing this AD to prevent smoke and fumes in the cockpit in the event that a blower motor seizes and overheats due to excessive current draw.
Airworthiness Directives; Liberty Aerospace Incorporated Model XL-2 Airplanes
We are adopting a new airworthiness directive (AD) for certain Liberty Aerospace Incorporated Model XL-2 airplanes. This AD requires you to repetitively inspect the exhaust muffler for cracks and to replace the exhaust muffler when cracks are found. This AD is the result of reports that cracks have been found in the exhaust muffler during maintenance and service inspections. We are issuing this AD to detect and correct cracks in the exhaust muffler, which could result in carbon monoxide entering the cabin through the heating system. Carbon monoxide entering into the airplane cabin could lead to incapacitation of the pilot.
Notice of Final Federal Agency Actions on Proposed Highway in California
The FHWA, on behalf of Caltrans, is issuing this notice to announce actions taken by Caltrans and USFWS that are final within the meaning of 23 U.S.C. 139(l)(1). The actions relate to a proposed highway project (US 101) and local road extension (Union Valley Parkway), in the community of Orcutt and City of Santa Maria in the County of Santa Barbara, State of California. Those actions grant licenses, permits, and approvals for the project.
Hazardous Materials: Miscellaneous Cargo Tank Motor Vehicle and Cylinder Issues; Petitions for Rulemaking
PHMSA is amending the Hazardous Materials Regulations to revise certain requirements applicable to the manufacture, maintenance, and use of DOT and MC specification cargo tank motor vehicles, DOT specification cylinders and UN pressure receptacles. The revisions are based on petitions for rulemaking submitted by the regulated community and are intended to enhance the safe transportation of hazardous materials in commerce, clarify regulatory requirements, and reduce operating burdens on cargo tank and cylinder manufacturers, requalifiers, carriers, shippers, and users. The most significant
Airworthiness Directives; Honeywell Flight Management Systems (FMSs) Equipped With Honeywell NZ-2000 Navigation Computers and Honeywell IC-800 or IC-800E Integrated Avionics Computers; as Installed on Various Transport Category Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to all Honeywell FMSs served by Honeywell NZ-2000 navigation computers and IC-800 integrated avionics computers. That AD currently requires identifying affected computers by part number and software modification level and revising the Limitations section of applicable airplane flight manuals to provide procedures for retaining optimum position determination and intended navigation. This new AD requires upgrading new software, which terminates the existing requirements. This AD results from reports of in-flight unannunciated shifts of computed position in airplanes with the subject FMS computers. We are issuing this AD to prevent a shift in the FMS computed position, which could result in uncommanded deviations from the intended flight path of the airplane, and, if those deviations are undetected by the flight crew, compromised terrain/traffic avoidance.
Airworthiness Directives; Bell Helicopter Textron Canada Limited Model 206A, 206B, 206L, 206L-1, 206L-3, 206L-4, 222, 222B, 222U, 230, 407, 427, and 430 Helicopters
We are adopting a superseding airworthiness directive (AD) for the specified Bell Helicopter Textron Canada Limited (BHTC) Model 206A, 206B, 206L, 206L-1, 206L-3, 206L-4, 222, 222B, 222U, 230, 407, 427, and 430 helicopters. That AD currently requires replacing each affected tail rotor blade (blade) with an airworthy blade that has a serial number not listed in the Rotor Blades, Inc. (RBI) document that is attached to each of the Bell Helicopter Textron Alert Service Bulletins (ASBs) listed in the applicability section of the AD. That AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of Canada. The MCAI states that there have been three reports of blade tip weights departing from the blade during flight. Since issuing that AD, BHTC has issued revised service information to correct part numbers and serial numbers listed in the RBI document that is attached to each BHTC ASB and to add additional part-numbered and serial-numbered blades to the list. The actions of this AD are intended to prevent loss of a blade tip weight, loss of a blade, and subsequent loss of control of the helicopter.
Airworthiness Directives; MD Helicopters, Inc. Model MD900 (including the MD902 Configuration) Helicopters
This amendment adopts a new airworthiness directive (AD) for the specified MD Helicopters, Inc. (MDHI) model helicopters that requires, within 30 days, reducing the current gross weight limit to a maximum gross weight limit of 5,400 pounds and inserting a copy of this AD into the Limitations section of the Rotorcraft Flight Manual (RFM) or making certain optional modifications that constitute terminating actions. This amendment is prompted by flight tests that show that the information currently listed in the Limitations section of the RFM is inconsistent with the actual performance of the helicopter. The actions specified by this AD are intended to prevent loss of directional control of the helicopter.
Notice of Intent To Prepare an Environmental Impact Statement for the George Bush Intercontinental Airport, Houston, TX and To Conduct Public Scoping Meetings
The FAA is issuing this Notice of Intent to advise the public that the FAA will prepare an EIS under the provisions of the National Environmental Policy Act (NEPA) of 1969, as amended. The EIS will
Airworthiness Directives; Boeing Model 737-300, -400, and -500 Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to all Boeing Model 737-300, -400, and -500 series airplanes. That AD currently requires repetitive inspections for discrepancies of the fuselage skin under the dorsal fin assembly, and repairing if necessary. This new AD requires an inspection for any chafing or crack in the fuselage skin and abrasion resistant coating at the dorsal fin landing, an inspection for damage to the dorsal fin seals, attach clip, and seal retainer, and other specified and corrective actions as necessary. The new requirements will end the need for the existing repetitive inspections. This AD results from a report of an 18-inch crack found in the fuselage skin area under the blade seals of the nose cap of the dorsal fin due to previous wear damage, and additional reports of fuselage skin wear. We are issuing this AD to prevent discrepancies of the fuselage skin, which could result in fatigue cracking due to cabin pressurization and consequent rapid in- flight decompression of the airplane fuselage.
