Airworthiness Directives; Airbus Helicopters
Document Number: 2021-20414
Type: Proposed Rule
Date: 2021-09-23
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede Airworthiness Directive (AD) 2021-04-21, which applies to certain Airbus Helicopters Model EC120B helicopters. AD 2021-04-21 requires an inspection of the attachment bolts of the main rotor (MR) hub scissors assembly for discrepancies and repair if necessary; part marking of the attachment bolts of the MR hub scissors assembly; and repetitive inspections of the part marking of the attachment bolts, and repair if necessary. Since the FAA issued AD 2021-04-21, the FAA has determined that additional part marking of the washer, scissor branch, and mast ring of the corresponding nut side, and repetitive inspections of the additional part markings are necessary. This proposed AD would continue to require the actions in AD 2021-04-21; and also would require part marking of the washer, scissor branch, and mast ring of the corresponding nut side, and repetitive inspections of the additional part markings and repair if necessary; 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; Airbus Helicopters Deutschland GmbH Helicopters
Document Number: 2021-20413
Type: Proposed Rule
Date: 2021-09-23
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH Model EC135P2+, EC135P3, EC135T2+, and EC135T3 helicopters. This proposed AD was prompted by reports that certain aft and forward fitting assemblies, which are not approved for installation on certain helicopters, were installed on those helicopters as part of the outboard load system. Operators of those helicopters might not be aware of the applicable overhaul or life limits for those fitting assemblies. This proposed AD would require inspecting the aft and forward fitting assemblies of the outboard load system to determine the part number, re-identifying the part if necessary, inspecting each affected part for damage (which may be indicated by signs of corrosion, mechanical damage, loose rivets, or cracks) and, depending on the findings, corrective actions, 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; Airbus Helicopters Deutschland GmbH Helicopters
Document Number: 2021-20409
Type: Proposed Rule
Date: 2021-09-23
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, and EC135T3 helicopters. This proposed AD was prompted by reduced life limits being established for certain part-numbered tail rotor (TR) blades. This proposed AD would require determining the total hours time-in-service (TIS) of certain part-numbered TR blades, establishing a life limit for certain part-numbered TR blades, removing from service any TR blade that has reached or exceeded its life limit, creating a component history card, re-identifying certain part-numbered TR blades, and removing any TR blade from service before reaching its retirement life. This proposed AD would also prohibit installing certain TR blades on certain model helicopters. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bell Textron Inc. (Type Certificate Previously Held by Bell Helicopter Textron Inc.) Helicopters
Document Number: 2021-20408
Type: Rule
Date: 2021-09-23
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Bell Textron Inc. (type certificate previously held by Bell Helicopter Textron Inc.) Model 205B helicopters. This AD was prompted by a notification of certain parts needing a life limit. This AD requires determining the total hours time-in-service (TIS) of certain part-numbered main rotor grip assemblies (grip assemblies), establishing a life limit for certain part-numbered grip assemblies, removing from service any grip assembly that has reached or exceeded its retirement life, creating a component history card, and removing any grip assembly from service before reaching its retirement life. This AD also prohibits installing certain grip assemblies unless the life limit was established in accordance with this AD. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters
Document Number: 2021-20407
Type: Proposed Rule
Date: 2021-09-23
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS355NP helicopters. This proposed AD was prompted by a report of mechanical deformation found on the protective cover (also referred to as switch guard) of the ``SHEAR'' control pushbutton installed on a co-pilot collective stick of a Model EC225LP helicopter, caused by incorrect handling; due to having an identical design switch guard installed on the pilot collective stick, Model AS355NP helicopters are also affected. This proposed AD would require replacement of the protective cover of the ``SHEAR'' control pushbutton, and re-identification of the pilot collective stick, 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; Airbus SAS Airplanes
Document Number: 2021-20405
Type: Proposed Rule
Date: 2021-09-23
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This proposed AD was prompted by reports of slat transmission jams caused by frozen slat geared rotary actuators (SGRA) at slat 5 track 12. This proposed AD would require repetitive water drainage and plug cleaning of the left- and right-hand SGRA having a certain part number installed on slat 5 track 12 with certain functional item numbers, 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.
