Federal Aviation Administration February 10, 2022 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for all Fiberglas-Technik Rudolf Lindner GmbH & Co. KG (type certificate previously held by GROB Aircraft AG, Grob Aerospace GmbH i.l., Grob Aerospace GmbH, Burkhart Grob Luftund Raumfahrt GmbH & Co. KG) Model G102 ASTIR CS, G103 TWIN ASTIR, G103 TWIN II, G103A TWIN II ACRO, G103C TWIN III ACRO, and G 103 C TWIN III SL gliders. This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as corrosion on the elevator control pushrod. This AD requires inspecting the elevator control pushrod for water and corrosion and replacing the pushrod if necessary. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 80-13-10, AD 80-13-12 R1, and AD 2008-03-01, which applied to certain de Havilland (type certificate now held by Viking Air Limited) Model DHC- 6-1, DHC-6-100, DHC-6-200, and DHC-6-300 airplanes. AD 80-13-10 required repetitively inspecting the main landing gear (MLG) legs for cracks and corrosion. AD 80-13-12 R1 required repetitively inspecting each engine nacelle lower longeron for cracks and buckling. AD 2008-03- 01 required incorporating inspections, modifications, and life limits of certain structural components into the aircraft maintenance program. Since the FAA issued those ADs, new and more restrictive airworthiness limitations have been issued for certain structural components. This AD requires incorporating into maintenance records new or revised life limits, modification limits, and inspection or overhaul intervals. The FAA is issuing this AD to address the unsafe condition on these products.

This action modifies the Class E airspace extending upward from 700 feet above the surface of the earth, and removes the Class E airspace extending upward from 1,200 feet above the surface of the earth at Gold Beach Municipal Airport, Gold Beach, OR. This action would ensure the safety and management of instrument flight rules (IFR) operations at the airport.

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC120B helicopters. This AD was prompted by a report of geometrical non-conformities in the tail rotor blade (TRB) root section discovered during an accident investigation of a Model EC130B helicopter. Due to the similarity of design and production requirements, certain TRBs for the Model EC120B helicopters were inspected and geometrical non-conformities were also found. This AD requires an inspection (dimensional check) to verify conformity, and replacement of certain TRBs 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 is adopting a new airworthiness directive (AD) for certain Sikorsky Aircraft Corporation Model S-76D helicopters. This AD was prompted by reports that certain Thales global positioning system (GPS) satellite based augmentation system (SBAS) receivers provided, under certain conditions, erroneous outputs on aircraft positions. This AD requires replacing affected GPS receivers and prohibits installing those GPS receivers. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model AB412 and AB412 EP helicopters. This AD was prompted by a report that certain oil and fuel check valves are susceptible to cracking. This AD requires determining whether the affected oil and fuel check valves are installed, visually inspecting the oil and fuel check valves for any crack, and depending on the inspection results, removing certain parts from service. This AD also requires removing affected parts from service and installing serviceable parts, and prohibits the installation of affected parts 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 is adopting a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH (AHD) Model MBB-BK 117 C-2 and MBB- BK 117 D-2 helicopters. This AD was prompted by report that a collective bellcrank-K was found incorrectly installed on a helicopter. This AD requires inspecting the collective bellcrank-K to determine if it is correctly installed and has a correct position marking and, depending on the findings, applicable corrective actions, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also allows installation of an affected collective bellcrank-K, provided certain instructions are followed. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model BD-100-1A10 airplanes. This AD was prompted by a report that the design of the spoiler control system causes certain engine indication and crew alerting system (EICAS) messages to be posted intermittently and repetitively during flight and on the ground, and flightcrews must action the appropriate checklist each time these messages appear. This AD requires revising the Non-Normal Procedures section of the existing airplane flight manual (AFM) associated with the spoiler electronic control unit (SECU) EICAS messages. 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 Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500- 1A11 airplanes. This AD was prompted by reports of loose or disconnected powerplant FIREX interconnection hoses. This AD requires replacing certain existing FIREX hose assemblies with a newly designed FIREX hose assembly, as specified in a Transport Canada Civil Aviation (TCCA) 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 all Airbus Helicopters Model EC 155B and EC155B1 helicopters. This proposed AD was prompted by a report of a discrepancy in the rotorcraft flight manual (RFM) where the rotorcraft stay-up flying capabilities for Category B operation were provided through performance data only, not as airworthiness limitations that are dependent upon on the number of passengers on board. This proposed AD would require revising the existing RFM for your helicopter, 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.

This action proposes to amend the Class E airspace at Emmetsburg, IA. The FAA is proposing this action as the result of an airspace review caused by the decommissioning of the Emmetsburg non- directional beacon (NDB). The geographic coordinates of the airport would also be updated to coincide with the FAA's aeronautical database.
