Airworthiness Directives; Eurocopter Deutschland GmbH Helicopters
Document Number: 2013-00311
Type: Proposed Rule
Date: 2013-01-10
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for Eurocopter Deutschland GmbH (Eurocopter) Model BO-105A, BO-105C, BO- 105S, BO-105LS A-1, BO-105LS A-3, EC135 P1, EC135 P2, EC135 P2+, EC135 T1, EC135 T2, EC135 T2+, MBB-BK 117 A-1, MBB-BK 117 A-3, MBB-BK 117 A- 4, MBB-BK 117 B-1, MBB-BK 117 B-2, MBB-BK 117 C-1, and MBB-BK 117 C-2 helicopters with certain part-numbered cantilever assemblies, cyclic stick locking devices, or cyclic stick holder assemblies installed. This proposed AD would require modifying and identifying the cyclic stick cantilever or lock. This proposed AD is prompted by pilots inadvertently taking off with the cyclic locked. The proposed actions are intended to prevent a pilot taking off with the cyclic in the locked position, which could result in loss of control of the helicopter.
Establishment of VOR Federal Airway V-629; Las Vegas, NV
Document Number: 2013-00289
Type: Rule
Date: 2013-01-10
Agency: Federal Aviation Administration, Department of Transportation
This action establishes VHF omnidirectional range (VOR) Federal airway V-629, near Las Vegas, NV, to supplement the existing routes structure for aircraft navigating in an area of marginal radar coverage. This action enhances the safety and efficiency of the National Airspace System.
Airworthiness Directives; Turbomeca S.A. Turboshaft Engines
Document Number: 2013-00130
Type: Rule
Date: 2013-01-10
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all Turbomeca S.A. Arriel 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 1K1, 1S, and 1S1 turboshaft engines. This AD requires performing a high gas generator speed (NG) rating vibration check. This AD was prompted by several reports of uncommanded in-flight shutdown on Arriel 1 engines. We are issuing this AD to prevent an uncommanded in- flight shutdown of the engine, which could result in an emergency landing.
Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Turbofan Engines
Document Number: 2013-00128
Type: Rule
Date: 2013-01-10
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Tay 620-15 turbofan engines. This AD requires a one-time inspection of the low-pressure compressor (LPC) fan blades and if erosion is found their replacement before further flight. This AD was prompted by evidence of excessive leading edge erosion of the LPC fan blades on certain Tay 620-15 engines. We are issuing this AD to prevent failure of the LPC fan blade, which could result in uncontained engine failure and damage to the airplane.
Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Turbofan Engines
Document Number: 2012-31588
Type: Rule
Date: 2013-01-10
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 turbofan engines. This AD requires a one-time removal from service of the high-pressure (HP) compressor stages 1 to 6 rotor disc assembly before exceeding certain thresholds. This AD was prompted by a report of silver chloride-induced stress corrosion cracking of the HP compressor stages 1 to 6 rotor disc assembly, identified during overhaul. We are issuing this AD to prevent failure of the HP compressor stages 1 to 6 rotor disc assembly, which could result in uncontained failure of the engine and damage to the airplane.
