Federal Aviation Administration April 22, 2021 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Uninsured United Parachute Technologies, LLC Parachutes
Document Number: 2021-08460
Type: Rule
Date: 2021-04-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Uninsured United Parachute Technologies, LLC (UPT) parachutes. This AD results from reserve pin covers (RPCs) catching on the parachute container flaps and preventing the reserve parachute from deploying. This AD requires modifying the RPC before the next parachute jump and replacing the RPC at the next reserve parachute packing. The FAA is issuing this AD to address the unsafe condition on these products.
Establishment of Class E Airspace; Calais, ME
Document Number: 2021-08349
Type: Rule
Date: 2021-04-22
Agency: Federal Aviation Administration, Department of Transportation
This action amends Class E airspace extending upward from 700 feet above the surface for Calais Regional Heliport, Calais, ME. The FAA discovered that necessary language was inadvertently omitted to the description of the airspace that excluded airspace outside of the United States.
Airworthiness Directives; Pratt & Whitney Turbofan Engines
Document Number: 2021-08327
Type: Rule
Date: 2021-04-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding Airworthiness Directive (AD) 2012-04-15 for all Pratt & Whitney (PW) JT9D-3A, JT9D-7, JT9D-7A, JT9D-7AH, JT9D- 7F, JT9D-7H, JT9D-7J, JT9D-7Q, JT9D-7Q3, JT9D-7R4D, JT9D-7R4D1, JT9D- 7R4E, JT9D-7R4E1, JT9D-7R4E4, JT9D-7R4G2, JT9D-7R4H1, JT9D-20, JT9D- 20J, JT9D-59A, and JT9D-70A (JT9D) model turbofan engines. AD 2012-04- 15 required revisions to the Airworthiness Limitations Section (ALS) of the manufacturer's Instructions for Continued Airworthiness (ICA) to include required enhanced inspection of selected critical life-limited parts at each piece-part opportunity. AD 2012-04-15 also required additional revisions to the ALS of the manufacturer's ICA for JT9D model turbofan engines. This AD requires revising the required inspections of selected critical life-limited parts specified in the ALS of the manufacturer's ICA and, for air carriers, to the existing continuous airworthiness air carrier maintenance program (CAMP). The FAA is issuing this AD to address the unsafe condition on these products.
Proposed Amendment, Establishment, and Revocation of Multiple Air Traffic Service (ATS) Routes in the Vicinity of Neosho, MO
Document Number: 2021-08284
Type: Proposed Rule
Date: 2021-04-22
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to amend Jet Route J-181 and VHF Omnidirectional Range (VOR) Federal airways V-13, V-14, V-15, and V- 307; establish Area Navigation (RNAV) routes T-411 and T-413; and remove VOR Federal airway V-506. The FAA is proposing this action due to the planned decommissioning of the VOR portion of the Neosho, MO (EOS), VOR/Distance Measuring Equipment (VOR/DME) navigation aid (NAVAID). The Neosho VOR is being decommissioned in support of the FAA's VOR Minimum Operational Network (MON) program.
Airworthiness Directives; Airbus SAS Airplanes
Document Number: 2021-08202
Type: Proposed Rule
Date: 2021-04-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede Airworthiness Directive (AD) 2017-12-13, which applies to certain Airbus SAS Model A320-212, -214, - 232, and -233 airplanes. AD 2017-12-13 requires repetitive low frequency eddy current inspections or repetitive high frequency eddy current inspections of the pocket radius at certain areas of the fuselage frame, and repair if necessary. Since the FAA issued AD 2017- 12-13, it was determined that cracks can initiate and develop between certain other fuselage frames of the pocket radii and additional airplanes are subject to the unsafe condition. This proposed AD would require new repetitive inspections at the left- (LH) and right-hand (RH) sides of the fuselage skin at certain frames for any cracking, and repair if necessary, as specified in a European Union Aviation Safety Agency (EASA), which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters
Document Number: 2021-08183
Type: Proposed Rule
Date: 2021-04-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede Airworthiness Directive (AD) 2014-11-02 for Airbus Helicopters Model SA-365N, SA-365N1, AS-365N2, and AS 365 N3 helicopters. AD 2014-11-02 requires repetitively inspecting frame number (No.) 9 for a crack. Since the FAA issued AD 2014-11-02, Airbus Helicopters developed a modification that would provide an optional terminating action for the repetitive inspections required by AD 2014-11-02. This proposed AD would retain the requirements of AD 2014-11-02, provide an optional terminating action for the repetitive inspections, and reduce the applicability by excluding certain post-modified helicopters. The actions of this proposed AD are intended to address an unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters
Document Number: 2021-08182
Type: Proposed Rule
Date: 2021-04-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. This proposed AD was prompted by a report of a yaw control failure that was the result of the disconnection of the tail rotor hub (TRH) pitch control rod from the tail rotor servo-control, which resulted from a seized TRH bearing. The TRH bearing had grease dissolving after contamination by leaked hydraulic fluid from the tail rotor servo-control that came through the TRH assembly boot. This proposed AD would require repetitive inspections for hydraulic leaks, corrective actions if necessary, and an optional modification which constitutes terminating action, 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
Document Number: 2021-08179
Type: Proposed Rule
Date: 2021-04-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Model EC155B1 helicopters. This proposed AD was prompted by a report of difficulties when jettisoning the co- pilot door during non-scheduled maintenance. This proposed AD would require a functional check of the pilot and co-pilot door jettisoning system and corrective actions if necessary, as specified in a European 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; Rolls-Royce Deutschland Ltd & Co KG (Type Certificate Previously Held by Rolls-Royce plc) Turbofan Engines
Document Number: 2021-07660
Type: Proposed Rule
Date: 2021-04-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede Airworthiness Directive (AD) 2020-15-12, which applies to certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Trent 1000 model turbofan engines. AD 2020-15-12 requires initial and repetitive ultrasonic or visual inspections of the intermediate-pressure compressor (IPC) stage 1 rotor blade root (front face), IPC stage 2 rotor blade root (front and rear face), and IPC shaft stage 2 dovetail post (front face), and removal of any cracked parts from service. AD 2020-15-12 also requires an inspection after asymmetric power and cabin depressurization events. Since the FAA issued AD 2020-15-12, the manufacturer introduced IPC stage 1 and stage 2 rotor blades in kitted sets, which terminate the need for initial and repetitive ultrasonic or visual inspections for certain IPC parts. This proposed AD would continue to require initial and repetitive ultrasonic or visual inspections of certain IPC parts until replacement of the IPC stage 1 and stage 2 rotor blades with redesigned IPC stage 1 and stage 2 rotor blades in kitted sets. The FAA is proposing this AD to address the unsafe condition on these products.
