Federal Aviation Administration June 20, 2013 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Bell Helicopter Textron Canada Limited (Bell) Helicopters
Document Number: 2013-14704
Type: Proposed Rule
Date: 2013-06-20
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for Bell Model 206L, L-1, L-3, and L-4 helicopters. This proposed AD would require measuring each main rotor (M/R) blade spar space to determine whether it is oversized and reidentifying the blade and reducing the life limit of the blade if the spar spacer is oversized. This proposed AD is prompted by the manufacture of certain main rotor blades with an oversized spar spacer and the determination to reduce the life limits of those main rotor blades. The proposed actions are intended to prevent failure of a M/R blade and subsequent loss of control of the helicopter.
Airworthiness Directives; Eurocopter France Helicopters
Document Number: 2013-14703
Type: Proposed Rule
Date: 2013-06-20
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, AS350D, AS350D1, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters with sliding doors, except those with modification AL.4262. This proposed AD would require removing from service certain part-numbered nuts and washers from the lower ball- joint bolt. This proposed AD is prompted by a report of a sliding door detaching from the helicopter in flight. The proposed actions are intended to prevent loss of the lower ball-joint nut, which could lead to loss of the sliding door and damage to the helicopter.
Airworthiness Directives; Eurocopter France Helicopters
Document Number: 2013-14701
Type: Proposed Rule
Date: 2013-06-20
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model AS332C, AS332L, AS332L1, AS332L2, and EC225LP helicopters. This proposed AD would require visually inspecting each jettisonable emergency exit window panel (window) for sealant, and removing any sealant that exists in the window's extruded sections. This proposed AD is prompted by jettison tests during routine maintenance inspections that showed the windows failed to jettison. The proposed actions are intended to prevent failure of the windows to jettison, so helicopter occupants can exit the aircraft during an emergency.
Airworthiness Directives; Sikorsky Aircraft Corporation (Sikorsky) Model Helicopters
Document Number: 2013-14699
Type: Proposed Rule
Date: 2013-06-20
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for Sikorsky Model S-76A, B, and C helicopters to require certain inspections of each spindle cuff assembly or blade fold cuff assembly for a crack. If there is a crack, this proposed AD would require replacing the cracked part. If there is no crack, this AD would require applying white paint to the inspection area to enhance the existing inspection procedure. This proposed AD is prompted by the discovery of cracks in the spindle cuffs. The proposed actions are intended to prevent failure of a spindle cuff assembly or blade fold cuff assembly, loss of a rotor blade, and subsequent loss of control of the helicopter.
Airworthiness Directives; Eurocopter Deutschland GmbH (ECD) Helicopters
Document Number: 2013-14697
Type: Proposed Rule
Date: 2013-06-20
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for ECD Model BO105C (C-2 and CB-2 Variants) and BO105S (CS-2 and CBS-2 Variants) helicopters with a certain third stage turbine wheel installed. This proposed AD would require installing a placard on the instrument panel and revising the limitations section of the rotorcraft flight manual (RFM). This proposed AD is prompted by several incidents of third stage engine turbine wheel failures, which were caused by excessive vibrations at certain engine speeds during steady-state operations. The proposed actions are intended to alert pilots to avoid certain engine speeds during steady-state operations, prevent failure of the third stage engine turbine, engine power loss, and subsequent loss of control of the helicopter.
Airworthiness Directives; Agusta S.p.A. (Type Certificate Currently Held by AgustaWestland S.p.A) (Agusta) Helicopters
Document Number: 2013-14694
Type: Proposed Rule
Date: 2013-06-20
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for Agusta Model A109A, A109AII, and A109C helicopters with a certain third stage turbine wheel installed. This proposed AD would require installing a placard on the instrument panel and revising the limitations section of the rotorcraft flight manual (RFM). This proposed AD is prompted by several incidents of third stage engine turbine wheel failures, which were caused by excessive vibrations at certain engine speeds during steady-state operations. The proposed actions are intended to alert pilots to avoid certain engine speeds during steady-state operations, prevent failure of the third stage engine turbine, engine power loss, and subsequent loss of control of the helicopter.
Airworthiness Directives; Bell Helicopter Textron Canada (Bell) Model Helicopters
Document Number: 2013-14693
Type: Proposed Rule
Date: 2013-06-20
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for Bell Model 206L-4 and 407 helicopters. This proposed AD would require replacing or reworking certain aft bearing caps. This proposed AD is prompted by the manufacture of certain freewheel aft bearing caps without a lubrication channel to allow oil flow into the aft bearing support assembly. The proposed actions are intended to prevent failure of the freewheel unit and subsequent loss of control of the helicopter.
Modification of VOR Federal Airway V-537, GA
Document Number: 2013-14660
Type: Rule
Date: 2013-06-20
Agency: Federal Aviation Administration, Department of Transportation
This action modifies VHF omnidirectional range (VOR) Federal airway V-537 in Georgia due to the scheduled decommissioning of the Moultrie, GA, VOR/DME navigation aid which currently forms a point along the route.
Establishment of Area Navigation (RNAV) Routes; Washington, DC
Document Number: 2013-14658
Type: Rule
Date: 2013-06-20
Agency: Federal Aviation Administration, Department of Transportation
This action corrects a final rule published by the FAA in the Federal Register on May 21, 2013, that establishes five RNAV routes in support of the Washington, DC, Optimization of Airspace and Procedures in a Metroplex project. This correction changes the name of one waypoint (WP) in the legal descriptions of RNAV routes T-291 and T-295.
Amendment of VOR Federal Airways V-55 and V-169 in Eastern North Dakota
Document Number: 2013-14657
Type: Rule
Date: 2013-06-20
Agency: Federal Aviation Administration, Department of Transportation
This action amends VHF Omnidirectional Range (VOR) Federal airways V-55 and V-169 in eastern North Dakota. The FAA is taking this action to amend the airway descriptions contained in Part 71 by removing reference to special use airspace (SUA) exclusionary language no longer needed.
