Federal Aviation Administration 2021 – Federal Register Recent Federal Regulation Documents

These special conditions are issued for the magniX USA, Inc., (magniX), magni350 and magni650 model engines, which operate using electrical technology installed on the aircraft for use as an aircraft engine. These engines have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards applicable to aircraft engines. This design feature is an electric motor, controller, and high-voltage systems as the primary source of propulsion for an aircraft. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

This action revokes VHF Omnidirectional Range (VOR) Federal airway V-271 and amends VOR Federal airway V-285 in the vicinity of Manistee, MI. This action is necessary due to the planned decommissioning of the VOR portion of the Manistee, MI, VOR/Distance Measuring Equipment (VOR/DME), which provides navigational guidance for these airways. The Manistee VOR is being decommissioned as part of the FAA's VOR Minimum Operational Network (MON) program.

The FAA proposes to adopt a new airworthiness directive (AD) for Bell Textron Canada Limited Model 206L-1, 206L-3, and 206L-4 helicopters with certain Air Comm Corporation (Air Comm) air conditioning systems installed. This proposed AD would require visually inspecting the drive ring spline teeth and the mating area spline teeth on the oil cooler blower shaft for signs of deformation and fretting and depending on the results of the inspection, removing certain parts from service. This proposed AD would also require reinstalling certain parts, applying torque, and aligning certain bolt holes. This proposed AD was prompted by reports of damage to the drive ring spline teeth and the mating spline teeth. The actions of this proposed AD are intended to address an unsafe condition on these products.

This action revokes Colored Federal airway R-4 in central Alaska due to the scheduled decommissioning of the Bear Creek (BCC) Non-Directional Beacon (NDB) on December 2, 2021.

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.

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.

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.

The FAA is adopting a new airworthiness directive (AD) for all Pratt & Whitney PW1500G and PW1900G series turbofan engines with a certain high-pressure turbine (HPT) 1st-stage hub or HPT rotor 1st- stage blade retaining plate installed. This AD was prompted by a report from the manufacturer who determined that the HPT 1st-stage hub and HPT rotor 1st-stage blade retaining plate fail to meet the published life- cycle limits for each part. This AD requires removal and replacement of the HPT 1st-stage hub and HPT rotor 1st-stage blade retaining plate prior to reaching certain cycle limits. The FAA is issuing this AD to address the unsafe condition on these products.

This action establishes Class E surface airspace for East Hampton Airport, East Hampton, NY, to assist aircraft landing and departing the airport when the air traffic control tower is closed. In addition, this action amends Class D airspace by replacing the outdated term Airport/Facility Directory with the term Chart Supplement in the airport description and amends the radius and ceiling as the FAA deemed the airspace adjustments were necessary. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.

This action modifies the Class E airspace, designated as a surface area, at Lake Tahoe Airport, South Lake Tahoe, CA. This action removes the Class E airspace designated as an extension to a Class D or Class E surface area, and it modifies the Class E airspace extending upward from 700 feet above the surface. This action also implements two administrative updates to the Class E2's text header.

This action proposes to establish Class E airspace extending upward from 700 feet above the surface for Fulton Airport, Fulton, KY, to accommodate new area navigation (RNAV) global positioning system (GPS) standard instrument approach procedures (SIAPs) serving this airport. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request Office of Management and Budget (OMB) approval to renew an information collection. Fractional Ownership is a program that offers increased flexibility in aircraft ownership. Owners purchase shares of an aircraft and agree to share their aircraft with others having an ownership share in that same aircraft. Owners agree to put their aircraft into a ``pool'' of other shared aircraft and to lease their aircraft to another owner in that pool. This collection is necessary to ensure compliance with relevant safety regulations.

The FAA proposes to extend through March 26, 2022, the Coronavirus (COVID-19)-related limited, conditional waiver of the minimum slot usage requirement at John F. Kennedy International Airport (JFK), New York LaGuardia Airport (LGA), and Ronald Reagan Washington National Airport (DCA) that the FAA has already made available through October 30, 2021, for all international operations. Similarly, the FAA proposes to extend through March 26, 2022, its COVID-19-related limited, conditional policy for prioritizing flights canceled at designated International Air Transport Association (IATA) Level 2 airports in the United States, for purposes of establishing a carrier's operational baseline in the next corresponding season, for all international operations. These IATA Level 2 airports include Chicago O'Hare International Airport (ORD), Newark Liberty International Airport (EWR), Los Angeles International Airport (LAX), and San Francisco International Airport (SFO). This relief would be limited to slots and approved operating times used by any carrier for international operations only, through March 26, 2022, and would be subject to the same terms and conditions, with minor modifications, that the FAA has already applied to the relief that remains available through October 30, 2021. This notice invites stakeholders to submit comments with detailed supporting information relevant to FAA making a final decision. The FAA anticipates subsequently providing notice of its final decision.

The FAA is revising a notice of proposed rulemaking (NPRM) that applied to all Rolls-Royce Deutschland Ltd & Co KG (RRD) Trent 1000-A2, Trent 1000-AE2, Trent 1000-C2, Trent 1000-CE2, Trent 1000-D2, Trent 1000-E2, Trent 1000-G2, Trent 1000-H2, Trent 1000-J2, Trent 1000- K2, and Trent 1000-L2 model turbofan engines. This action revises the NPRM by requiring revision of the engine Time Limits Manual (TLM) life limits of certain critical rotating parts and direct accumulation counting (DAC) data files, 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. Since these actions would impose an additional burden over those in the NPRM, the agency is requesting comments on this SNPRM.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bell Textron Canada Limited (type certificate previously held by Bell Helicopter Textron Canada Limited) Model 505 helicopters. This proposed AD was prompted by the determination that reducing the pressure altitude limitations for certain fuel types is necessary. This proposed AD would require revising the existing Rotorcraft Flight Manal (RFM) for your helicopter. The FAA is proposing this AD to address the unsafe condition on these products.

This notice announces a meeting of the Drone Advisory Committee.

The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 777 airplanes. This AD was prompted by a report that an operator found solid rivets with missing heads at the left buttock line 25 on the sloping pressure deck web. This AD requires doing a detailed inspection of the left- and right-side sloping pressure deck at certain stations for any damaged solid rivets, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation (Gulfstream) Models GV and GV- SP airplanes. This proposed AD was prompted by the omission of a life limit in the airworthiness limitations section (ALS) of the maintenance manual for a certain main landing gear (MLG) trunnion pin. This proposed AD would require revising the ALS of your existing instructions for continued airworthiness (ICA) or inspection program for the airplane to establish a life limit of 20,000 flight cycles for the affected MLG trunnion pin. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for all Daher Aerospace (type certificate previously held by SOCATA) Models TB 20 and TB 21 airplanes. This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracks on the main landing gear (MLG) legs. This proposed AD would require repetitively inspecting the MLG and performing all applicable corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by a report of defects on the piston hole associated with the O2 saver feature that may prevent efficient deactivation of the O2 saver function. This AD requires amending the existing airplane flight manual (AFM) to incorporate a check and an operating limitation regarding the O2 saver function, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also limits the installation of affected parts under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 78- 02-03, which applies to all Piper Aircraft, Inc. (Piper), Model PA-23- 250 airplanes. AD 78-02-03 requires repetitively inspecting the stabilator tip tube and weight assemblies for cracks, inspecting for missing rivets and screws, replacing the forward rib/horn assemblies, and reinforcing the mounting. Since AD 78-02-03 was issued, Piper developed a newly-designed stabilator, which is not subject to the unsafe condition, and revised its service information. This proposed AD would retain the actions of AD 78-02-03, but would reduce the applicability and require the actions in the revised service information. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2020-26- 02, which applied to certain Yabor[atilde] Ind[uacute]stria Aeron[aacute]utica S.A. (type certificate previously held by Embraer S.A.) Model ERJ 190-400 airplanes. AD 2020-26-02 required amending the existing airplane flight manual (AFM) to incorporate a new limitation and revise certain normal procedures. This AD retains those requirements and also requires upgrading the electronic engine control (EEC) software, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is incorporated by reference. This AD was prompted by a report of an in-flight shutdown (IFSD) due in part to failure in the low-pressure compressor (LPC) rotor 1 during operation in high altitude at high thrust settings, and by the development of updated EEC software, which would terminate the requirement to amend the existing AFM. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain Fokker Services B.V. Model F28 Mark 0070 and Mark 0100 airplanes. This AD was prompted by a report of a crack found on the forward pressure bulkhead web plate, at the edge of a bonded doubler. This AD requires a one-time inspection of the forward bulkhead for cracking, repair if necessary, and a report of inspection results, as specified in a 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.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. This proposed AD was prompted by a report of a wing stall (wing drop/ un-commanded roll) during a landing flare. This proposed AD would require revising the existing airplane flight manual (AFM) to incorporate a limitation and procedure for the wing anti-ice (WAI) system in order to mitigate the risk of ice accumulation on the wing leading edges. The FAA is proposing this AD to address the unsafe condition on these products.
