Federal Aviation Administration December 21, 2021 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; De Havilland Aircraft of Canada Limited (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
Document Number: 2021-27709
Type: Rule
Date: 2021-12-21
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding Airworthiness Directive (AD) 2017-19- 09, which applied to certain De Havilland Aircraft of Canada Limited (Type Certificate Previously Held by Bombardier, Inc.) Model DHC-8-400 series airplanes. AD 2017-19-09 required modifying the nose landing gear (NLG) shock strut assembly. This new AD requires repetitive lubrications of the trailing arm of the NLG. This new AD also requires revising the existing maintenance or inspection program to include new and revised airworthiness limitations (life limits for certain bolts). This AD was prompted by reports of a certain bolt being found missing or having stress corrosion cracking. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
Document Number: 2021-27707
Type: Rule
Date: 2021-12-21
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS 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. This AD was prompted by the determination that fatigue cracking may occur at the wing manhole access panel attachment holes at certain wing skin panels on airplanes with Sharklets or its structural reinforcements installed. This AD requires repetitive inspections for cracking of the area, and corrective action 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.
Airworthiness Directives; Embraer S.A. Airplanes
Document Number: 2021-27511
Type: Rule
Date: 2021-12-21
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Embraer S.A. Model EMB-500 and EMB-505 airplanes. This AD was prompted by a report that the operational envelope does not contain airspeed limitations and procedures for operating the airplane at static air temperatures below -54 [deg]C. This AD requires revising the airplane flight manual (AFM) to incorporate new and revised airspeed limitations and procedures. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Piper Aircraft, Inc. Airplanes
Document Number: 2021-27510
Type: Rule
Date: 2021-12-21
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding Airworthiness Directive (AD) 78-02-03, which applied to all Piper Aircraft, Inc. (Piper) Model PA-23-250 airplanes. AD 78-02-03 required 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 AD retains the actions of AD 78-02-03, but reduces the applicability and requires the actions in the revised service information. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Viking Air Limited (Type Certificate Previously Held by Bombardier Inc.) Airplanes
Document Number: 2021-27509
Type: Proposed Rule
Date: 2021-12-21
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for Viking Air Limited (type certificate previously held by Bombardier Inc.) Model DHC-3 airplanes with a certain wing strut assembly installed. This proposed AD results from 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 identifies the unsafe condition as fatigue damage of the wing struts. This proposed AD would require a bolt hole eddy current inspection of the lug plate holes, a visual and fluorescent dye penetrant inspection of the lug fittings, and a visual and eddy current surface scan inspection of the wing strut assemblies. This unsafe condition could lead to failure of the wing strut, which could result in an in-flight breakup of the wing. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Pilatus Aircraft Ltd. Airplanes
Document Number: 2021-27507
Type: Rule
Date: 2021-12-21
Agency: Federal Aviation Administration, Department of Transportation
The FAA is superseding Airworthiness Directive (AD) 2012-06- 16, which applied to all Pilatus Aircraft Ltd. (Pilatus) Model PC-6, PC-6-H1, PC-6-H2, PC-6/350, PC-6/350-H1, PC-6/350-H2, PC-6/A, PC-6/A- H1, PC-6/A-H2, PC-6/B-H2, PC-6/B1-H2, PC-6/B2-H2, PC-6/B2-H4, PC-6/C- H2, and PC-6/C1-H2 airplanes. AD 2012-06-16 required installing a new rudder and elevator locking screw and modifying the installation of the rudder and elevator hinge bolt. Since the FAA issued AD 2012-06-16, the European Union Aviation Safety Agency (EASA) superseded its mandatory continuing airworthiness information (MCAI) to correct an unsafe condition on these products. This AD does not retain any actions required by AD 2012-06-16 and requires inspecting and modifying the rudder, elevator, and right-hand (RH) aileron hinge bolt installations. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; General Electric Company Turbofan Engines
Document Number: 2021-27480
Type: Rule
Date: 2021-12-21
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) CF34-8C and CF34-8E model turbofan engines. This AD was prompted by a report of a quality escape during the manufacturing of a high-pressure turbine (HPT) rotor stage 1 disk. This AD requires removing the HPT rotor stage 1 disk from service and replacing the HPT rotor stage 1 disk with a part eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
Document Number: 2021-27288
Type: Proposed Rule
Date: 2021-12-21
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede Airworthiness Directive (AD) 2018-09-09, which applies to certain Airbus Model A318 series airplanes and Model A319 series airplanes; all Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and all Model A321-111, -112, -131, - 211, -212, -213, -231, and -232 airplanes. AD 2018-09-09 requires modifying the holes of the upper cleat to upper stringer attachments at certain areas of the left-and right-hand wings. Since the FAA issued AD 2018-09-09, additional affected configurations were identified and, for certain airplanes, it was determined that additional modification work and revised compliance times are necessary. This proposed AD would retain the requirements of AD 2018-09-09 and add airplanes, require different compliance times for certain airplane configurations, and, for certain airplanes, require additional modifications or reduce compliance times, 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.
Deadline for Notification of Intent To Use the Airport Improvement Program (AIP) Primary, Cargo, and Nonprimary Entitlement Funds Available to Date for Fiscal Year 2022.
Document Number: 2021-27533
Type: Notice
Date: 2021-12-21
Agency: Federal Aviation Administration, Department of Transportation
This action announces February 15, 2022, as the deadline for each airport sponsor to notify the FAA if it will use its Fiscal Year (FY) 2022 entitlement funds to accomplish Airport Improvement Program (AIP) eligible projects. Each sponsor has previously identified to the FAA such projects through the Airports Capital Improvement Plan process. This action further announces April 11, 2022, as the deadline for an airport sponsor to submit a final grant application, based on bids, for grants that will be funded with FY 2022 entitlements funds only.
