Document Number: 2021-12662
Type: Rule
Date: 2021-06-16
Agency: Federal Aviation Administration, Department of Transportation
This action modifies the Class E airspace extending upward from 1,200 feet above the surface at Missoula International Airport, Missoula, MT.
Airworthiness Directives; Airbus SAS Airplanes
Document Number: 2021-12603
Type: Proposed Rule
Date: 2021-06-16
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede Airworthiness Directive (AD) 2019-20-10, which applies to certain Airbus SAS Model A318 series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2019-20-10 requires repetitive rototest inspections of the holes at the door stop fittings for any cracking, and corrective actions if necessary. Since the FAA issued AD 2019-20-10, a clarification of a certain compliance time for the rototest inspection was added. This proposed AD would clarify a certain compliance time and continue to require repetitive rototest inspections of the holes at the door stop fittings for any cracking, and repair if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Proposed Amendment and Removal of Class E Airspace; South Lake Tahoe, CA
Document Number: 2021-12601
Type: Proposed Rule
Date: 2021-06-16
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to modify the Class E airspace, designated as a surface area, at Lake Tahoe Airport, South Lake Tahoe, CA. This action also proposes to remove the Class E airspace designated as an extension to a Class D or Class E surface area and modify the Class E airspace extending upward from 700 feet above the surface. Also, this action proposes two administrative updates to the Class E2's text header. This action would ensure the safety and management of instrument flight rules (IFR) operations at the airport.
Airworthiness Directives; Airbus Helicopters and Airbus Helicopters Deutschland GmbH (AHD) Helicopters
Document Number: 2021-12517
Type: Proposed Rule
Date: 2021-06-16
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for Airbus Helicopters Model AS332C, AS332C1, AS332L, AS332L1, AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350D, AS355E, AS355F, AS355F1, AS355F2, AS355N, AS355NP, AS-365N2, AS 365 N3, EC120B, EC130B4, EC130T2, EC 155B, EC155B1, SA-365N, and SA-365N1 helicopters; and Airbus Helicopters Deutschland GmbH (AHD) Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, EC135T3, MBB-BK117 C-2, and MBB-BK117 D-2 helicopters. This proposed AD was prompted by failure of an Emergency Flotation System (EFS) float compartment to inflate during maintenance of the EFS. This proposed AD would require inspecting certain EFSs and depending on the results, marking certain parts or removing certain parts from service, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Leonardo S.p.a.
Document Number: 2021-12516
Type: Rule
Date: 2021-06-16
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model AW189 helicopters. This AD was prompted by a report of the bubble window departing from the helicopter during flight. This AD requires installation of a new improved bubble window kit, as specified in a European Aviation Safety Agency (now the European Union Aviation Safety Agency) (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Leonardo S.p.a. Helicopters
Document Number: 2021-12515
Type: Proposed Rule
Date: 2021-06-16
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for Leonardo S.p.a. (Leonardo) Model AB139 and AW139 helicopters with certain main rotor blades MRB installed. This proposed AD was prompted by a report of an in-flight loss of a main rotor blade (MRB) tip cap. This proposed AD would require inspecting the MRB tip cap for disbonding. The FAA is proposing this AD to address the unsafe condition on these products.
