Federal Aviation Administration August 2021 – Federal Register Recent Federal Regulation Documents

This rule amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide for the safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

This action revokes the Class E airspace extending upward from 700 feet above the surface at Standish Industrial Airport, Standish, MI. This action is the result of an airspace review caused by the closing of the Standish Industrial Airport and associated instrument procedures are no longer required.

This action amends the Class E airspace extending upward from 700 feet above the surface at Pocahontas Municipal Airport, Pocahontas, IA. This action is the result of an airspace review due to the decommissioning of the Pocahontas non-directional beacon (NDB). Additionally, the geographical coordinates of the airport are also being updated to coincide with the FAA's aeronautical database, which was inadvertently omitted in the NPRM docket.

The FAA is superseding Airworthiness Directive (AD) 2020-23- 13, which applied to all ATRGIE Avions de Transport R[eacute]gional Model ATR42-200, -300, and -320 airplanes. AD 2020-23-13 required a one-time inspection for discrepancies of the wire bundles between the left- and right-hand angle of attack (AOA) probes and the crew alerting computer, and, depending on findings, applicable corrective actions. This AD continues to require the actions in AD 2020-23-13, and also requires for certain airplanes, modifying the captain stick shaker wiring, and for all airplanes, revising the existing aircraft flight manual (AFM) and applicable corresponding operational procedures to incorporate procedures for the stick pusher/shaker, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by false activation of the stall warning system due to wiring damage on the wire bundle between an AOA probe and the crew alerting computer, and the development of a wiring modification and AFM update to address the unsafe condition. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2017-12- 13, which applied to certain Airbus SAS Model A320-212, -214, -232, and -233 airplanes. AD 2017-12-13 required 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. This AD requires 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) AD, which is incorporated by reference. This AD was prompted by a report of a crack found during an inspection of the pocket radius of the fuselage frame, and a determination that similar cracks may develop in nearby areas of the fuselage frame and that additional airplanes are subject to the unsafe condition. The FAA is issuing this AD to address the unsafe condition on these products.

This notice contains a summary of a petition seeking relief from specified requirements of Federal Aviation Regulations. The purpose of this notice is to improve the public's awareness of, and participation in, FAA's exemption process. Neither publication of this notice nor the inclusion nor omission of information in the summary is intended to affect the legal status of the petition or its final disposition.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval to renew an information collection. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on March 16, 2021. The FAA collects information from U.S. and foreign air carriers holding or requesting a slot at Ronald Reagan Washington National Airport (DCA), John F. Kennedy International Airport (JFK), and LaGuardia Airport (LGA); operating or requesting scheduled flights at Newark Liberty International Airport (EWR), Los Angeles International Airport (LAX), O'Hare International Airport (ORD), and San Francisco International Airport (SFO); and conducting unscheduled operations at DCA and LGA. The information collected is necessary to support the advance management of air traffic demand by the FAA Slot Administration in an effort to reduce potential delays. The FAA proposes renaming this information collection to ``FAA Runway Slot Administration and Schedule Analysis'' to more accurately reflect the collection of information related to multiple airports subject to different FAA regulatory and voluntary processes under this program.

This action proposes to amend United States Area Navigation route (RNAV) Q-15 in order to safely segregate overflight, arrival and departure traffic, and military operations in the high altitude airspace between Las Vegas, NV and Phoenix, AZ.

The FAA proposes to supersede Airworthiness Directive (AD) 2011-07-02, which applies to all Pratt & Whitney (P&W) JT8D-209, JT8D- 217, JT8D-217A, JT8D-217C, and JT8D-219 model turbofan engines. AD 2011-07-02 requires initial and repetitive torque inspections of the 3rd-stage and 4th-stage low-pressure turbine (LPT) blades. AD 2011-07- 02 also requires replacement of the LPT blade if wear limits are exceeded, replacement of the LPT-to-exhaust case bolts and nuts, and installation of crushable sleeve spacers on the bolts. Since the FAA issued AD 2011-07-02, the FAA received a report of an MD-82 airplane, equipped with a JT8D-217 engine, experiencing an engine surge that resulted in the fracture of an LPT blade. This proposed AD would retain certain requirements of AD 2011-07-02, while revising the inspection thresholds and replacement intervals for the 3rd-stage and 4th-stage LPT blades. The FAA is proposing this AD to address the unsafe condition on these products.

This action amends Class E airspace extending upward from 700 feet above the surface in Muscle Shoals, AL, due to the decommissioning of the Muscle Shoals Very High Frequency Omni-Directional Radio Range Tactical Air Navigation Aid (VORTAC), and cancellation of the associated approach at Northwest Alabama Regional Airport. This action also updates the airport name under the Class E surface airspace and makes an editorial change replacing the term Airport/Facility Directory with the term Chart Supplement in the legal descriptions of associated Class E airspace. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.

The FAA proposes to adopt a new airworthiness directive (AD) for all ASI Aviation (type certificate previously held by Reims Aviation S.A.) Model F406 airplanes. This proposed 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 failure of a circuit breaker (CB) switch. This proposed AD would require replacing certain CB switches and establishing a life limit for the CB switches. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2015-16-07 R1, which applies to certain Reims Aviation S.A. (type certificate now held by ASI Aviation) Model F406 airplanes. AD 2015-16- 07 R1 requires inspecting the left-hand and right-hand rudder control pedal torque tubes and replacing with a serviceable part as necessary. Since the FAA issued AD 2015-16-07 R1, the European Aviation Safety Agency (EASA) superseded its mandatory continuing airworthiness information (MCAI) to correct an unsafe condition on these products. This proposed AD would retain the requirements of AD 2015-16-07 R1, expand the applicability, and require repeating the inspections using updated procedures. The FAA is proposing this AD to address the unsafe condition on these products.

This action proposes to amend the Class D and Class E airspace at Ardmore, OK. The FAA is proposing this action as the result of airspace reviews due to the decommissioning of the Arbuckle non- directional beacon (NDB). The geographic coordinates of the airport would also be updated to coincide with the FAA's aeronautical database.

The FAA is superseding Airworthiness Directive (AD) 2021-11- 03, which applied to certain Airbus Helicopters Model EC 155B, EC155B1, SA-365N, SA-365N1, AS-365N2, and AS 365 N3 helicopters. AD 2021-11-03 required inspecting the main gearbox (MGB) fixed cowling front fitting (MGB front fitting), and depending on findings, corrective action. This AD retains the requirements of AD 2021-11-03, and includes service information that was omitted for Airbus Helicopter Model EC 155B and EC155B1 helicopters, as specified in a European Aviation Safety Agency (now 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.

This notice contains a summary of a petition seeking relief from specified requirements of Federal Aviation Regulations. The purpose of this notice is to improve the public's awareness of, and participation in, FAA's exemption process. Neither publication of this notice nor the inclusion nor omission of information in the summary is intended to affect the legal status of the petition or its final disposition.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Leonardo S.p.a. Model A109E helicopters. This proposed AD was prompted by reports of cracking in the center fuselage frame assembly in the intersection of the lateral pylon and floor spar at station (STA) 1815 on the left- and right-hand sides. This proposed AD would require repetitive inspections of the intersection of the lateral pylon and floor spar at STA 1815 for cracking and, depending on the findings, repair, 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 proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Model AS332L2 and EC225LP helicopters. This proposed AD was prompted by a design deficiency. This proposed AD would require modifying the hoist control power supply, 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 withdrawing a notice of proposed rulemaking (NPRM) that proposed to adopt a new airworthiness directive (AD) that would have applied to certain Airbus Canada Limited Partnership Model BD-500- 1A10 airplanes. The NPRM would have required an inspection of the low- pressure distribution supply duct to determine the part number, and replacement if necessary, as specified in a Transport Canada Civil Aviation (TCCA) AD. Since issuance of the NPRM, the FAA has determined that the affected operator has already addressed the unsafe condition by incorporating the proposed required actions on the affected airplanes. Accordingly, the NPRM is withdrawn.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd. & Co KG (RRD) Trent 1000 model turbofan engines. This proposed AD was prompted by the manufacturer revising the engine Time Limits Manual (TLM) life limits of certain critical rotating parts and direct accumulation counting data files. This proposed AD would require the operator to revise the airworthiness limitation section (ALS) of their existing approved aircraft maintenance program (AMP) by incorporating the revised tasks of the applicable TLM for each affected model turbofan engine, 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 proposes to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) CF34-10E model turbofan engines. This proposed AD was prompted by a manufacturer investigation that revealed Teflon material in the A-sump oil strainer (strainer assembly) screen after several reports of in-flight shutdowns (IFSDs) and unscheduled engine removals (UERs). This proposed AD would require initial and repetitive visual inspections of the strainer assembly screen. As a terminating action to the initial and repetitive visual inspections, this proposed AD would require the replacement of the stationary oil seal at the No. 1 forward bearing. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2018-19-28, which applies to certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 ECJ, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes; and AD 2014-16-16, which applies to all of those airplane models. AD 2014-16-16 requires, for certain airplanes, retorquing and replacing the pylon lower link fittings, and for all airplanes, repetitively retorquing those fittings. AD 2018-19-28 requires modifying the attaching parts of the pylon lower link fittings. Since the FAA issued AD 2014-16-16 and AD 2018-19-28, the FAA finds it necessary to change the compliance time for the modification. This proposed AD would require an inspection of certain shear pins, replacement if necessary, and revised compliance times for the modification, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) 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 certain Airbus Defense and Space S.A. Model C-212-CB, C-212-CC, C-212- CD, C-212-CE, C-212-CF, C-212-DE, and C-212-DF airplanes. This AD was prompted by a report of cracks on the left-hand (LH) and right-hand (RH) side fuselage skin and on a certain frame underneath the skin, near the leading edge of the wing. This AD requires repetitive inspections of the LH and RH side center wing fairings at a certain frame, around the wing leading edge for discrepancies (cracks), and repair if necessary, 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 supersede Airworthiness Directive (AD) 2017-23-02, which applies to certain The Boeing Company Model 737-200, -200C, -300, -400, and -500 series airplanes. AD 2017-23-02 requires repetitive inspections, replacement, and applicable on-condition actions for certain fuselage crown skin panels. Since the FAA issued AD 2017-23-02, certain airplane configurations and inspection locations have been revised and additional airplanes have been determined to be subject to the unsafe condition. This proposed AD would retain the actions in AD 2017-23-02, revise certain airplane configurations and inspection locations, and add airplanes to the applicability. The FAA is proposing this AD to address the unsafe condition on these products.

These special conditions are issued for the Bombardier Model CL-600-2B16 (Bombardier) airplane. This airplane, as modified by Pro Star Aviation LLC (Pro Star Aviation), will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. This design feature is a system that emits infrared laser energy outside the aircraft as a countermeasure against heat-seeking missiles. 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.

The FAA is superseding Airworthiness Directive (AD) 2020-19-11 for certain Leonardo S.p.a. Model A119 and AW119 MKII helicopters. AD 2020-19-11 required repetitive borescope inspections of the 90-degree tail rotor gearbox (TGB) and depending on the inspection results, removing the TGB from service. This AD was prompted by the determination that additional parts may be susceptible to the unsafe condition. This AD retains the inspection requirements of AD 2020-19-11, and revises the compliance time and applicability. The FAA is issuing this AD to address the unsafe condition on these products.
