Notice of Request To Release Airport Property
The FAA proposes to rule and invites public comment on the release of land at Sioux Gateway Airport/Col. Bud Day Field, Sioux City, Iowa, under the provisions of 49 U.S.C. 47107(h)(2).
Airworthiness Directives; Eurocopter Deutschland GmbH Helicopters
We propose to adopt a new airworthiness directive (AD) for certain Eurocopter Deutschland GmbH (Eurocopter) Model EC135P2+ and EC135T2+ helicopters. This proposed AD would require inspecting the mechanical air conditioning system compressor bearing block upper bearing (upper bearing) for corrosion, leaking grease, condensation, or water. This proposed AD is prompted by metallic debris from an upper bearing found in the air inlet areas of both engines in a Model EC135P2+ helicopter. The proposed actions are intended to prevent metallic debris from damaging the engine, causing loss of engine power, and subsequent loss of helicopter control.
Airworthiness Directives; Sikorsky Aircraft Corporation (Sikorsky) Helicopters
We propose to supersede an existing airworthiness directive (AD) for Sikorsky Model S-76A, B, and C helicopters. The existing AD currently requires inspecting the main rotor lower bifilar arm assembly (bifilar arm assembly) for a crack, and if there is a crack, replacing the bifilar arm assembly. The AD also requires a one-time test for the correct torque on the lug nuts, and if necessary, conducting torque stabilization tests. Since we issued that AD, Sikorsky has developed a terminating procedure for the inspections required by the existing AD. This proposed AD would retain the requirements of that AD, and would require replacing the main rotor hub (MRH) pilot with a different part- numbered MRH pilot, which would be terminating action for the requirements of the AD. The proposed actions are intended to prevent failure of a bifilar lug, damage to the main rotor control system, and subsequent loss of control of the helicopter.
Airworthiness Directives; Sikorsky Aircraft Corporation (Sikorsky) Helicopters
We propose to adopt a new airworthiness directive (AD) for Sikorsky Model S-70, S-70A, and S-70C helicopters. This proposed AD would establish a new life limit based on a prorated formula for certain identified components (parts) installed on Model S-70, S-70A, and S-70C helicopters after being previously installed on certain military model helicopters. This proposed AD is prompted by the discovery that certain parts have been interchanged between military helicopter models with different life limits and the possibility that these same parts can be interchanged with civilian models with different life limits. The proposed actions are intended to establish a pro-rated in service life limit for each identified part to prevent fatigue failure of a part and subsequent loss of control of the helicopter.
Airworthiness Directives; Eurocopter France Helicopters
We propose to adopt a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model EC225LP helicopters. This proposed AD would require inspecting the swashplates for corrosion or a crack, and making the appropriate repairs or replacement of parts. This proposed AD is prompted by the discovery of corrosion on the swashplates when the main rotor hub (MRH) assemblies were reconditioned. The proposed actions are intended to detect corrosion or a crack in the swashplates, which could lead to failure of the swashplate and subsequent loss of helicopter control.
Airworthiness Directives; Sikorsky Aircraft Corporation (Sikorsky) Model Helicopters
We are revising an earlier proposed airworthiness directive (AD) for the Sikorsky Model S-70, S-70A, S-70C, S-70C (M), and S-70C (M1) helicopters with General Electric (GE) T700-GE-401C or T700-GE- 701C engines installed, which proposed establishing new fatigue life limits for certain GE engine gas generator turbine (GGT) rotor parts. The proposed AD was prompted by a reevaluation of the method for determining the life limit for certain GE engine gas generator turbine (GGT) rotor parts and the determination that these life limits need to be based on low cycle fatigue (LCF) events instead of hours time-in- service. This action would retain the previously proposed requirements but correct the life limit formula for a certain GGT rotor part. The proposed actions are intended to prevent fatigue failure of a GGT rotor part, engine failure, and subsequent loss of control of the helicopter.
Airworthiness Directives; Eurocopter Deutschland GmbH Helicopters
We propose to adopt a new airworthiness directive (AD) for Eurocopter Deutschland GmbH (Eurocopter) Model MBB-BK 117 C-2 helicopters with a jettisonable sliding door (door) installed. This proposed AD would require inspecting the lock release assembly and the middle and upper lever locking bolts of each door, replacing any damaged parts with airworthy parts, and ensuring the door is correctly installed. This proposed AD is prompted by the uncommanded detaching of a door from an MBB-BK 117 C-2 fuselage. The proposed actions are intended to prevent the in-flight loss of the door, which could damage the helicopter and injure persons on the ground.
Airworthiness Directives; Agusta S.p.A. Helicopters (Type Certificate Currently Held By AgustaWestland S.P.A) (AgustaWestland)
We propose to adopt a new airworthiness directive (AD) for AgustaWestland Model A109S, AW109SP, A119, and AW119 MKII helicopters to require removing certain rod end assemblies from service. This proposed AD is prompted by reports of fractures on the rod end assemblies that could damage the main rotor assembly and lead to loss of control of the helicopter.
Amendment of Class E Airspace; Tri-Cities, TN
This action amends Class E airspace for the Tri-Cities, TN area, by correcting the regulatory text of the Class E surface airspace at Tri-Cities Regional Airport, Tri-Cities, TN. Exclusionary language was omitted in the final rule published in the Federal Register of February 5, 2013, This action is necessary for the safety and management of Instrument Flight Rules (IFR) operations in the Tri- Cities area.
