Airworthiness Directives; Sikorsky Aircraft Corporation Helicopters

We propose to adopt a new airworthiness directive (AD) for certain Sikorsky Aircraft Corporation (Sikorsky) Model S-76C helicopters. This proposed AD is prompted by a bird-strike to the windshield that resulted in unintended movement of the engine control levers from the forward position and towards the flight-idle position, which reduced power on both engines. These actions are intended to prevent unintended movement of the ECLs, resulting in main rotor speed decay and subsequent loss of con...

This proposed AD was prompted by incorrect positioning of the roller drive pocket recesses on the tail rotor drive shaft free-wheel cage, which caused a pilot to experience a heavy jerk in the ...

Airworthiness Directives; Bell Helicopter Textron Canada Helicopters

We propose to adopt a new airworthiness directive (AD) for the Bell Helicopter Textron Canada Limited (BHTC) Model 407 helicopters. This proposed AD is prompted by a review of the tailboom-attachment installation, which revealed that the torque value of the bolts specified in the BHTC Model 407 Maintenance Manual and applied during manufacturing was incorrect and exceeded the torque range recommended for the bolts. This proposed AD would require you to replace tailboom- attachment hardware (a...

Channel Spacing and Bandwidth Limitations for Certain Economic Area (EA)-Based 800 MHz Specialized Mobile Radio (SMR) Licensees

This document proposes to modify the Commission's rules to allow Economic Area (EA)-based 800 MHz Specialized Mobile Radio (SMR) licensees to exceed a channel spacing and bandwidth limitation, subject to two conditions. The Commission proposes to allow licensees to exceed the channel spacing and bandwidth limitation in the 813.5-824/858.5-869 MHz band in National Public Safety Planning Advisory Committee (NPSPAC) regions where 800 MHz public safety licensee reconfiguration is complete. In are...

Reinforced Concrete in Construction, and Preventing Backover Injuries and Fatalities

OSHA is aware of employee safety risks in two areas, reinforcing operations in concrete work (construction only) and fatal backovers by vehicles and equipment (all industries), and is requesting information from the public on these risks. This RFI requests information that will assist the Agency in determining what steps, if any, it can take to prevent injuries and fatalities in these two areas.

Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Nonattainment New Source Review; Fine Particulate Matter (PM2.5

EPA is proposing to approve a State Implementation Plan (SIP) revisions submitted by the Commonwealth of Pennsylvania. These revisions pertaining to Pennsylvania's nonattainment New Source Review (NSR) program incorporate preconstruction permitting regulations for fine particulate matter (PM<INF>2.5</INF>) into the Pennsylvania SIP. EPA is approving these revisions in accordance with the requirements of the Clean Air Act (CAA).

Airworthiness Directives; MD Helicopters, Inc.

We propose to supersede an existing airworthiness directive (AD) for MD Helicopters, Inc. (MDHI) Model MD900 helicopters. The existing AD requires a visual inspection, and if necessary, an eddy current inspection of the main rotor lower hub assembly (lower hub) for a crack. If a crack exists, the AD requires replacing the lower hub with an airworthy lower hub before further flight. Because that AD was immediately effective, we did not include in its requirements certain long-term actions that...

Airworthiness Directives; Eurocopter France Helicopters

We propose to adopt a new airworthiness directive (AD) for Eurocopter France Model SA341G helicopters. This proposed AD is prompted by an analysis and tests performed by the manufacturer that indicate that the life limit of the rotating star should be 12,000 hours time-in-service (TIS). The proposed actions are intended to prevent failure of the rotating star and subsequent loss of control of the helicopter.
