Type: Proposed Rule
Date: 2013-09-04
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to establish Class E airspace at Ennis- Big Sky Airport, Ennis, MT. Controlled airspace is necessary to accommodate aircraft using new Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedures at Ennis-Big Sky Airport, Ennis, MT.

Type: Proposed Rule
Date: 2013-09-04
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to establish Class E Airspace at Star, NC, to accommodate a new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) serving Montgomery County Airport. This action would enhance the safety and airspace management of Instrument Flight Rules (IFR) operations within the National Airspace System.
Proposed Establishment of Class E Airspace; Chatom, AL
Document Number: 2013-21498
Type: Proposed Rule
Date: 2013-09-04
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to establish Class E Airspace at Chatom, AL, to accommodate the Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures at Roy Wilcox Airport. This action would enhance the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2013-21397
Type: Rule
Date: 2013-09-04
Agency: Federal Aviation Administration, Department of Transportation
We are superseding airworthiness directive (AD) 90-23-14 for certain The Boeing Company Model 747 series airplanes. AD 90-23-14 required inspections of the fuselage skin lap splice between body station (BS) 340 and BS 400 at stringers (S)-6L and S-6R, and repair if necessary. This new AD adds new repetitive inspections for cracking in the S-6 skin lap splice, which terminates the inspections required by AD 90-23-14; eventual modification of the lap splice, which terminates the repetitive inspections; post-modification inspections; and corrective actions if necessary. This AD also adds airplanes to the applicability. This AD was prompted by a report of cracks up to 18.5 inches that were found at S-6L and S-6R on several airplanes, and subsequent analysis results that indicated that the protruding head fastener modification and related post-modification inspections required by AD 90-23-14 are not adequate to prevent cracking at the upper row of fasteners in the S-6 lap joint before the cracks reach a critical length. We are issuing this AD to detect and correct cracking at the upper row of fasteners in the S-6 lap joint, which could result in a sudden loss of cabin pressurization and the inability of the fuselage to withstand failsafe loads.
Tenth Meeting: RTCA Next Gen Advisory Committee (NAC)
Document Number: 2013-21374
Type: Notice
Date: 2013-09-04
Agency: Federal Aviation Administration, Department of Transportation
The FAA is issuing this notice to advise the public of the tenth meeting of the RTCA NextGen Advisory Committee (NAC).
Airworthiness Directives; Various Aircraft Equipped With Rotax Aircraft Engines 912 A Series Engine
Document Number: 2013-21329
Type: Rule
Date: 2013-09-04
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for various aircraft equipped with Rotax Aircraft Engines 912 A Series Engine. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as oil leaks in the intake channel in the area of the valve guide on some cylinder heads could increase the oil consumption and result in engine stoppage. We are issuing this AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
Document Number: 2013-21071
Type: Rule
Date: 2013-09-04
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This AD was prompted by reports that certain trimmable horizontal stabilizer actuators (THSA) were found with corrosion that affected the ballscrew lower splines between the tie-bar and screw-jack. This AD requires repetitive inspections of the THSA; ballscrew integrity tests, if necessary; and replacement of affected THSAs. We are issuing this AD to detect and correct corrosion in the ballscrew lower splines, which, if the ballscrew ruptured, could lead to transmission of THSA torque loads from the ballscrew to the tie-bar, prompting THSA blowback, and possible loss of control of the airplane.
Airworthiness Directives; Eurocopter France Helicopters
Document Number: 2013-20238
Type: Rule
Date: 2013-09-04
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Eurocopter France (Eurocopter) Model AS350 and AS355 helicopters. This AD requires inspecting the tail rotor control stop screws to determine if they are correctly aligned and adjusting the screws if they are misaligned. This AD is prompted by the discovery of a loose nut on the tail rotor control stop and a misaligned tail rotor control stop screw. The actions of this AD are intended to detect a loose nut or a misaligned stop screw, which, if not corrected, could limit yaw authority, and consequently, result in a loss of helicopter control.
Airworthiness Directives; Eurocopter Deutschland GmbH Helicopters
Document Number: 2013-19500
Type: Rule
Date: 2013-09-04
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all Eurocopter Deutschland GmbH (ECD) EC 135 P1, P2, P2+, T1, T2, and T2+ helicopters equipped with a certain main transmission housing upper part. This AD requires installing a corrugated washer in the middle of the main transmission filter housing upper part and modifying the main transmission housing upper part. This AD was prompted by an inspection of housing upper parts that revealed the bypass inlet in the oil filter area was not manufactured in accordance with applicable design specifications. The actions of this AD are intended to prevent failure of the main transmission and subsequent loss of control of the helicopter.
