Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
The FAA is adopting a new airworthiness directive (AD) for MHI RJ Aviation ULC Model CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2C11 (Regional Jet Series 550), CL-600-2D15 (Regional Jet Series 705), CL-600-2D24 (Regional Jet Series 900), and CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by reports and a design review indicating that there could be possible corrosion on the main landing gear (MLG) outer cylinder at the interface with the gland nut on the shock strut installation and on the forward and aft trunnion pins in the MLG dressed shock strut assembly. This AD requires detailed inspections for corrosion on the MLG outer cylinder assemblies, certain MLG dressed shock strut assemblies, and the MLG outer cylinder at the gland nut threads, thread relief groove, and chamfer; a detailed inspection for the presence of corrosion-inhibiting compound (CIC) on the MLG forward and aft trunnion pins and grease adapter assemblies; applicable corrective actions; application of primer, paint, and CIC as applicable; re-identification of certain part numbers; and marking of the MOD STATUS field of the nameplate of certain parts. The FAA is issuing this AD to address the unsafe condition on these products.
Extension of the Prohibition Against Certain Flights in Specified Areas of the Dnipro Flight Information Region (FIR) (UKDV)
This action amends and extends the Special Federal Aviation Regulation (SFAR) prohibiting certain flights in the specified areas of the Dnipro Flight Information Region (FIR) (UKDV) by all: U.S. air carriers; U.S. commercial operators; persons exercising the privileges of an airman certificate issued by the FAA, except when such persons are operating U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except when the operator of such aircraft is a foreign air carrier. The FAA finds this action necessary to address hazards to persons and aircraft engaged in such flight operations due to the continuing hostilities along the line of contact between Ukraine and Russian-backed separatists and heightened tensions between Russia and Ukraine. The FAA extends the expiration date of this Special Federal Aviation Regulation from October 27, 2021, until October 27, 2023. Additionally, the FAA republishes the approval process and exemption information for this SFAR, consistent with other recently published flight prohibition SFARs, and makes minor administrative revisions.
Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by significant changes, including new or more restrictive requirements, made to the airworthiness limitations (AWLs) related to fuel tank ignition prevention and the nitrogen generation system. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A300 series airplanes; Airbus SAS Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes); and Airbus SAS Model A310 series airplanes. This proposed AD was prompted by reports of incorrect installation of the fire shut- off valves (FSOV) actuator, which was found to rotate around its pivot axis. This proposed AD would require a one-time detailed inspection of the FSOV actuator for rotation around its pivot axis, and replacement if necessary, 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.
Airworthiness Directives; General Electric Company Turbofan Engines
The FAA proposes to supersede Airworthiness Directive (AD) 2020-20-13, which applies to certain General Electric Company (GE) CF6- 80A and CF6-80C model turbofan engines. AD 2020-20-13 requires ultrasonic inspection (UI) of high-pressure turbine (HPT) stage 1 and stage 2 disks and replacement of any HPT stage 1 or stage 2 disk that fails the inspection. Since the FAA issued AD 2020-20-13, the manufacturer determined that the requirement to perform UI of affected HPT stage 1 and stage 2 disks should be expanded to include an additional population of affected HPT stage 1 and stage 2 disks. This proposed AD would retain the required UI while expanding the population of affected HPT stage 1 and stage 2 disks. The FAA is proposing this AD to address the unsafe condition on these products.
Amendment of Class D and Class E Airspace; Portsmouth, NH
This action amends Class D airspace and Class E airspace for Portsmouth International Airport at Pease, Portsmouth, NH, due to the decommissioning of the PEASE Very High Frequency Omnidirectional Range Collocated with Distance Measuring Equipment (VOR/DME) and cancellation of the standard instrument associated approach procedures (SIAPs). This action also updates the airport's name and geographic coordinates. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.
