Airworthiness Directives; BAE SYSTEMS (Operations) Limited Model BAe 146 Airplanes and Model Avro 146-RJ Airplanes
The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to all Model BAe 146 airplanes and Model Avro 146-RJ airplanes. The original NPRM would have superseded an existing AD that currently requires revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate life limits for certain items and inspections to detect fatigue cracking in certain structures. The original NPRM proposed to require incorporating new and more restrictive life limits for certain items and for certain inspections to detect fatigue cracking in certain structures. The original NPRM resulted from issuance of a later revision to the airworthiness limitations. This new action revises the original NPRM by proposing to require revisions to the airworthiness limitations to include Critical Design Configuration Control Limitations for the fuel system. We are proposing this supplemental NPRM to ensure that fatigue cracking of certain structural elements is detected and corrected, and to prevent ignition sources in the fuel tanks; fatigue cracking of certain structural elements could adversely affect the structural integrity of these airplanes.
Airworthiness Directives; Fokker Services B.V. Model F.28 Mark 0070 and 0100 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: Due to their position on the airplane, fuel fire shut-off valve actuators P/N [part number] 9409122 are susceptible to freezing, which has an adverse effect on the operation of the valve. Also, due to various causes, the failure rate of [fuel fire shut-off valve] actuator P/N 9409122 is higher than expected. Failure or freezing of the actuator may prevent the flight crew to close the fuel fire shut-off valve in case of an engine fire. Due to their position on the aeroplane, fuel crossfeed valve actuators P/N 9409122 are susceptible to freezing, which has an adverse effect on the operation of the valve. This condition, if not corrected, may generate fuel asymmetry alerts when a valve remains in the open position after being selected closed. It may also prevent the flight crew from correcting a fuel asymmetry when a valve remains in the closed position after being selected open. One event was reported where, due to such problems, the flight crew shut down an engine in-flight and diverted the aircraft. [D]ue to their position on the aircraft, ice may form on actuators P/N 9409122 installed on fuel crossfeed valves and fuel fire shut-off valves. Tests revealed that the ice can prevent the actuator and thus the valve from operating in flight (frozen stuck).
Airworthiness Directives; AeroSpace Technologies of Australia Pty Ltd Models N22B, N22S, and N24A Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. 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: The results of full scale fatigue tests being conducted by the manufacturer have shown the need for inspection of critical fastener holes in the stub wing upper front spar cap, near the wing strut attachment. The proposed AD would require
Preparation of an Alternatives Analysis and Environmental Impact Statement for High Capacity Transit Improvements for the Indianapolis Northeast Corridor in the Indiana Counties of Marion and Hamilton
The Federal Transit Administration (FTA), the Central Indiana Regional Transportation Authority (CIRTA), the Indianapolis Metropolitan Planning Organization (Indianapolis MPO) and Indianapolis Public Transportation Corporation (IndyGo) intend to prepare an Alternatives Analysis/Environmental Impact Statement (AA/EIS) relating to proposed high capacity transit improvements in the Northeast Corridor located in the Indiana counties of Marion and Hamilton. The study area is an approximately 23-mile long travel corridor extending from downtown Indianapolis to the northern parts of Noblesville and includes the communities of Carmel and Fishers. Options to be considered include No-Build, Transportation System Management (TSM), Bus Rapid Transit (BRT), and Commuter Rail. The AA/EIS will be prepared in accordance with the requirements of the National Environmental Policy Act (NEPA) and its implementing regulations. The AA/EIS process provides opportunities for the public to comment on the scope of the EIS, including the project's purpose and need, the alternatives to be considered, and the impacts to be evaluated. The southern terminal of all alternatives will be Union Station or an adjacent transit center in downtown Indianapolis.
Seaway Regulations and Rules: Periodic Update, Various Categories
The Saint Lawrence Seaway Development Corporation (SLSDC) and the St. Lawrence Seaway Management Corporation (SLSMC) of Canada, under international agreement, jointly publish and presently administer the St. Lawrence Seaway Regulations and Rules (Practices and Procedures in Canada) in their respective jurisdictions. Under agreement with the SLSMC, the SLSDC is amending the joint regulations by updating the Seaway Regulations and Rules in various categories. The changes will update the following sections of the Regulations and Rules: Condition of Vessels; Radio Communications; and General. These amendments are necessary to take account of updated procedures and will enhance the safety of transits through the Seaway. Several of the proposed amendments are merely editorial or for clarification of existing requirements.
New Car Assessment Program (NCAP); Safety Labeling
Since September 2007, new passenger vehicles have been required to be labeled with safety rating information published by the National Highway Traffic Safety Administration (NHTSA) under its New Car Assessment Program (NCAP). This information is required to be part of the Monroney (automobile price sticker) label. In July 2008, NHTSA announced a decision to enhance the NCAP ratings program. In this document, the agency is proposing to upgrade its regulation on vehicle labeling of safety rating information to reflect the enhanced NCAP ratings program. NHTSA is proposing, among other things, to include a new overall vehicle score on the Monroney label.
Hazardous Materials: Risk-Based Adjustment of Transportation Security Plan Requirements
PHMSA, in consultation with the Transportation Security Administration (TSA) of the Department of Homeland Security (DHS), is modifying current security plan requirements applicable to the commercial transportation of hazardous materials by air, rail, vessel, and highway. Based on an evaluation of the security threats associated with specific types and quantities of hazardous materials, the final rule narrows the list of materials subject to security plan requirements and reduces associated regulatory costs and paperwork burden. The final rule also clarifies certain requirements related to security planning, training, and documentation.
Airworthiness Directives; Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This 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 Model DHC-8-102, DHC-8-103, DHC-8-106, DHC-8-201, and DHC-8-202 Series Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This 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.

Airworthiness Directives; The Boeing Company Model 747-100, 747-200B, 747-300, and 747SR Series Airplanes
We are adopting a new airworthiness directive (AD) for certain Model 747-100, 747-200B, 747-300, and 747SR series airplanes. This AD requires installation of a closeout panel and moisture curtains for the main equipment center. This AD results from a report of water contamination in the electrical and electronic units in the main equipment center. We are issuing this AD to prevent the malfunction of one or more electrical and electronic units in the main equipment center, which could adversely affect the airplane's continued safe flight.
Airworthiness Directives; The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 Series Airplanes
The FAA is superseding an existing airworthiness directive (AD) that applies to all Model 737-100, -200, -200C, -300, -400, and - 500 series airplanes. That AD currently requires a one-time inspection for scribe lines and cracks in the fuselage skin at certain lap joints, butt joints, external repair doublers, and other areas; and related investigative/corrective actions if necessary. This new AD expands the area to be inspected and, for certain airplanes, requires earlier inspections for certain inspection zones. This AD results from additional detailed analysis of fuselage skin cracks adjacent to the skin lap joints on airplanes that had scribe lines. The analysis resulted in different inspection zones, thresholds and repetitive intervals, and airplane groupings. We are issuing this AD to prevent rapid decompression of the airplane due to fatigue cracks resulting from scribe lines on pressurized fuselage structure.
