Federal Aviation Administration March 26, 2013 – Federal Register Recent Federal Regulation Documents

This action proposes to amend Class E airspace at Worthington, MN. Additional controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAP) at Worthington Municipal Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations for SIAPs at the airport. Geographical coordinates would also be updated.

This action proposes to establish Class E airspace at the Tobe VHF Omni-Directional Radio Range/Distance Measuring Equipment (VOR/ DME), Tobe, CO to facilitate vectoring of Instrument Flight Rules (IFR) aircraft under control of Denver and Albuquerque Air Route Traffic Control Centers (ARTCCs). The FAA is proposing this action to enhance the safety and management of aircraft operations within the National Airspace System.

This action proposes to establish Class E airspace at the Gillette VHF Omni-Directional Radio Range/Distance Measuring Equipment (VOR/DME), Gillette, WY to facilitate vectoring of Instrument Flight Rules (IFR) aircraft under control of Denver, Salt Lake City and Minneapolis Air Route Traffic Control Centers (ARTCCs). The FAA is proposing this action to enhance the safety and management of aircraft operations within the National Airspace System.

This action proposes to establish Class E airspace at Elbow Lake, MN. Controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAPs) at Elbow Lake Municipal-Pride of the Prairie Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations for SIAPs at the airport.

Pursuant to Section 10(a)(2) of the Federal Advisory Committee Act (Pub. L. 92-463, 5 U.S.C. App. 2), notice is hereby given of a meeting of the Commercial Space Transportation Advisory Committee (COMSTAC). The meeting will take place on Tuesday, May 14, 2013, from 8:00 a.m. to 5:00 p.m., and Wednesday, May 15, from 8:30 a.m. to 2:00 p.m., at the National Housing Center, 1201 15th Street NW., Washington, DC 20005. This will be the 57th meeting of the COMSTAC. The proposed schedule for the COMSTAC working group meetings on May 14 is below:

We propose to adopt a new airworthiness directive (AD) for Hartzell Propeller, Inc. propeller models HC-(1, D)2(X, V, MV)20-7, HC- (1, D)2(X, V, MV)20-8 and HC-(1, D)3(X, V, MV)20-8. This proposed AD was prompted by failures of the propeller hydraulic bladder diaphragm and resulting engine oil leak. This proposed AD would require replacement of the propeller hydraulic bladder diaphragm. We are proposing this AD to prevent propeller hydraulic bladder diaphragm rupture, loss of engine oil, damage to the engine, and loss of the airplane.

This action proposes to modify the legal description of VHF Omnidirectional Range (VOR) Federal airway V-345 in the vicinity of Ashland, WI. The Ashland (ASX) VOR Distance Measuring Equipment (VOR/ DME) navigation aid, which forms the northern most point of the airway, has been out of service for over ten months, with a Notice to Airmen (NOTAM) published, and is scheduled to be decommissioned in 2013. The FAA is proposing this action to remove that portion of V-345 affected by the loss of service by the Ashland, WI, VOR/DME.

This action amends VHF Omnidirectional Range (VOR) Federal Airway V-233 in the vicinity of Springfield, IL. The FAA is taking this action to correct the V-233 description contained in Part 71 to ensure it matches the information contained in the FAA's aeronautical database, matches the depiction on the associated charts, and ensures the safety and efficiency of the National Airspace System (NAS).

We are adopting a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model EC130 B4 helicopters with a cabin vibration damper installed. This AD requires installing a vibration damper casing assembly on both sides of the helicopter. This AD was prompted by a crack and failure of a cabin vibration damper blade. The actions of this AD are intended to modify the cabin vibration damper assembly to prevent contact with the flight controls in the event of a cabin vibration blade failure, jamming of a flight control, and subsequent loss of control of the helicopter.

We propose to supersede an existing airworthiness directive (AD) that applies to certain Bombardier, Inc. Model DHC-8-100, -200, and -300 series airplanes. The existing AD currently requires replacing certain parking brake accumulators. Since we issued that AD, we have determined that it is necessary to protect the hydraulic system and airplane structure from possible damage by any faulty screw cap or end cap of any accumulator. This proposed AD would require installing restraint devices around the parking brake accumulator end caps. We are proposing this AD to prevent failure of the parking brake accumulator screw cap or end cap resulting in loss of the number 2 hydraulic system and damage to airplane structures, which could adversely affect the controllability of the airplane.
