Airworthiness Directives; Honeywell International Inc. Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for all Honeywell International Inc. (Honeywell) ALF502L, ALF502L-2, ALF502L- 2A, ALF502L-2C, ALF502L-3, ALF502R-3, ALF502R-3A, ALF502R-4, ALF502R-5, ALF502R-6, LF507-1F, and LF507-1H model turbofan engines. This AD was prompted by a report of an engine experiencing an uncontained release of low-pressure turbine (LPT) blades. This AD requires initial and repetitive visual inspections of the overspeed fuel solenoid valve assembly and the fuel filter outlet. Depending on the results of these inspections, the AD may require inspection of the adjacent fuel system tube assemblies as well as replacement or overhaul of the overspeed fuel solenoid valve assembly. This AD also requires periodic overhaul of the overspeed fuel solenoid valve assembly. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; General Electric Company Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for all General Electric Company (GE) GE90-110B1 and GE90-115B model turbofan engines with a certain high-pressure turbine (HPT) rotor stage 2 disk installed. This AD was prompted by a report from the manufacturer that a subsurface anomaly was found on a HPT rotor stage 2 disk. This AD requires an ultrasonic inspection (USI) of the HPT rotor stage 2 disk and, depending on the result of the inspection, replacement of the HPT rotor stage 2 disk with a part eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Pilatus Aircraft Limited Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for Pilatus Aircraft Limited Model PC-12/47E airplanes. 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 describes the unsafe condition as inboard flap fairings aft (IFFAs) having an incorrect shape, which may result in chafing between the IFFA and the associated front inboard tension rod could occur. This proposed AD would require an inspection of the IFFAs for the correct shape and chafing between the IFFA and the associated front inboard tension rod, with corrective action as necessary. This condition could lead to failure of the inboard flap drive arm with consequent asymmetric flap extension, resulting in reduced control of the airplane. The FAA is proposing this AD to address the unsafe condition on these products.
Amendment of Class E Airspace; Clarion, IA
This action amends the Class E airspace extending upward from 700 feet above the surface at Clarion Municipal Airport, Clarion, IA. This action is the result of an airspace review due to the decommissioning of the Clarion non-directional beacon (NDB). The geographic coordinates of the airport are also being updated to coincide with the FAA's aeronautical database.
Amendment of Class E Airspace; Clinton, MO
This action amends the Class E airspace extending upward from 700 feet above the surface at Clinton Regional Airport, Clinton, MO. This action is the result of an airspace review due to the decommissioning of the Golden Valley non-directional beacon (NDB). The name and geographic coordinates of the airport are also being updated to coincide with the FAA's aeronautical database.
Airworthiness Directives; Airbus SAS Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A300 F4-605R airplanes and Model A310-324 airplanes. This proposed AD was prompted by a report that certain emergency locator transmitter (ELT) lithium batteries lack protection against current injection. This proposed AD would require modification of the airplane circuit connecting the ELT battery, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bell Textron Inc. (Type Certificate Previously Held by Bell Helicopter Textron Inc.) Helicopters
The FAA is adopting a new airworthiness directive (AD) for Bell Textron Inc. (Type Certificate previously held by Bell Helicopter Textron Inc.) (Bell), Model 204B, 205A-1, and 212 helicopters. This AD was prompted by reports of corrosion on main rotor hub tension-torsion strap (TT strap) assemblies. This AD requires reducing the life limit of a certain part-numbered TT strap assembly and prohibits installing this TT strap assembly on any helicopter. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Gulfstream Aerospace LP Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace LP Model Gulfstream G280 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 a Civil Aviation Authority of Israel (CAAI) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
Proposed Revocation of Class D and Amendment of Class E Airspace; Gillette, WY
This action proposes to remove the Class D airspace and modify the following: Class E surface area, the Class E airspace as an extension to the surface area and the Class E airspace extending upward from 700 feet AGL at Gillette-County Airport, Gillette, WY. In addition, this proposal would remove the VOR/DME from the legal description and replace the outdated term Airport Facility/Directory with the term Chart Supplement. After being informed that the Airport Traffic Control Tower at Gillette-County Airport is closed permanently, the FAA found it necessary to amend the existing airspace for the safety and management of Instrument Flight Rules (IFR) operations at this airport.
Subdivision of Restricted Area R-4101; Camp Edwards, MA
This action modifies restricted area R-4101 at Camp Edwards, MA, by vertically subdividing the area into R-4101A, R-4101B, and R- 4101C. Currently, R-4101 extends from the surface to 9,000 feet MSL. The FAA is taking this action to allow for more efficient use of the airspace during periods when military activities do not require the full vertical extent of restricted area R-4101. The modifications are fully contained within the existing lateral and vertical limits of R- 4101. The activities conducted in the airspace are unchanged.
