Airworthiness Directives; Dassault Aviation Airplanes
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.
Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG (Type Certificate Previously Held by Rolls-Royce plc) Turbofan Engines
The FAA is superseding Airworthiness Directive (AD) 2020-15-12 for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Trent 1000 model turbofan engines. AD 2020-15-12 required initial and repetitive ultrasonic or visual inspections of the intermediate-pressure compressor (IPC) stage 1 rotor blade root (front face), IPC stage 2 rotor blade root (front and rear face), and IPC shaft stage 2 dovetail post (front face), and removal of any cracked parts from service. AD 2020-15-12 also required an inspection after asymmetric power and cabin depressurization events. This AD was prompted by IPC rotor blade separations resulting in engine failures. This AD requires initial and repetitive ultrasonic or visual inspections of certain IPC stage 1 rotor blade root, IPC stage 2 rotor blade root, and IPC shaft stage 2 dovetail posts until replacement of the IPC stage 1 and stage 2 rotor blades with redesigned IPC stage 1 and stage 2 rotor blades in kitted sets. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Piper Aircraft, Inc. Airplanes
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.
Petition for Exemption; Summary of Petition Received; Airlines for America, Cargo Airline Association, National Air Carrier Association, and Regional Airline Association

Airworthiness Directives; Yaborã Indústria Aeronáutica S.A. (Type Certificate Previously Held by Embraer S.A.) Airplanes
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.
Amendment of Class D and Class E Airspace; Belleville, IL
This action amends the Class D and Class E airspace at Scott AFB/MidAmerica St. Louis Airport, Belleville, IL. This action is due to the results of a biennial airspace review. The name of the airport is also being updated to coincide with the FAA's aeronautical database.
