Airworthiness Directives; Piper Aircraft, Inc. Airplanes
The FAA is superseding Airworthiness Directive (AD) 2021-04-07 which applied to certain Piper Aircraft, Inc., (Piper) Models PA-46- 350P (Malibu Mirage), PA-46R-350T (Malibu Matrix), and PA-46-500TP (Malibu Meridian) airplanes. AD 2021-04-07 required identifying and correcting nonconforming stall warning heat control systems. Since AD 2021-04-07 was issued, the FAA was notified of an error in the stall warning heat control modification kit part number. This AD retains all of the actions in AD 2021-04-07 and corrects the incorrect modification kit part number. The FAA is issuing this AD to address the unsafe condition on these products.
Notice of Intent To Rule on a Request To Release Surplus Property at the Myrtle Beach International Airport, Myrtle Beach, South Carolina
The Federal Aviation Administration (FAA) is considering a request from the Horry County Department of Airports to waive the requirement that 0.29 acres of surplus property located at the Myrtle Beach International Airport be used for aeronautical purposes. Currently, the ownership of the property provides for the protection of approach and departure Runway Protection Zones and compatible land use which would continue to be protected with deed restrictions required in the transfer of land ownership.
Airworthiness Directives; Airbus SAS Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and -1041 airplanes. This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in two European Union Aviation Safety Agency (EASA) ADs, which are proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, and EC135T3 helicopters. This proposed AD would require modification of the tail rotor (T/R) control installation, a functional test, and corrective actions as necessary. This proposed AD is prompted by cases of insufficient clearance between a certain T/R control bearing connection and the helicopter structure, which were detected on the production line. The FAA is proposing this AD to address an unsafe condition on these products.
Proposed Amendment of Class E Airspace; Scott City, KS
This action proposes to amend the Class E airspace extending upward from 700 feet above the surface at Scott City Municipal Airport, Scott City, KS. The FAA is proposing this action as the result of an airspace review caused by the decommissioning of the Scott City non- directional beacon (NDB). The geographic coordinates of the airport would also be updated to coincide with the FAAs aeronautical database.
Airworthiness Directives; Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 airplanes. This proposed AD was prompted by a report that an incorrect low-pressure distribution supply duct may be installed in the forward cargo compartment. This proposed AD would require 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, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; General Electric Company Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for all General Electric Company (GE) GEnx-1B64, GEnx-1B64/P1, GEnx- 1B64/P2, GEnx-1B67, GEnx-1B67/P1, GEnx-1B67/P2, GEnx-1B70, GEnx-1B70/ 75/P1, GEnx-1B70/75/P2, GEnx-1B70/P1, GEnx-1B70/P2, GEnx-1B70C/P1, GEnx-1B70C/P2, GEnx-1B74/75/P1, GEnx-1B74/75/P2, GEnx-1B76/P2, GEnx- 1B76A/P2, GEnx-2B67, GEnx-2B67/P, and GEnx-2B67B model turbofan engines. This proposed AD was prompted by an in-service occurrence of loss of engine thrust control resulting in uncommanded high thrust. This proposed AD would require revising the operator's existing FAA- approved minimum equipment list (MEL) by incorporating into the MEL the dispatch restrictions listed in this AD. This proposed AD would also require initial and repetitive replacement of the electronic engine control (EEC) MN4 microprocessor. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. This proposed AD was prompted by reports of in- flight engine shutdowns (IFESs); investigation results indicated that this could be caused by high altitude climbs at higher thrust settings on engines with certain thrust ratings. This proposed AD would require amending the existing airplane flight manual (AFM) to incorporate a new limitation and revise certain normal procedures, as specified in a Transport Canada Civil Aviation (TCCA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
