Infrastructure and Investment Jobs Act Request for Information
FHWA seeks public input on the implementation of the Infrastructure and Investment Jobs Act.
Proposed Establishment and Proposed Amendment of Class E Airspace; Key Largo, FL
This action proposes to establish Class E surface airspace to accommodate Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAPs) serving Ocean Reef Club Airport. This action also proposes to amend Class E airspace extending upward from 700 feet above the surface for Ocean Reef Club Airport by updating the geographic coordinates of the airport and correcting the descriptor by replacing AL with FL. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.
Airworthiness Directives; Airbus SAS Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-200, -200 Freighter, -300, and -900 series airplanes; and Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by a report that during the frame of flight test clearance process, a detailed analysis of air data reference (ADR) failure scenarios led to the identification that compliance requirements for loads and handling qualities throughout the flight envelope could be impaired in case of dispatch with one ADR inoperative (master minimum equipment list (MMEL) item 34-10-01) during the maximum interval allowed by the current MMEL. This AD requires revising the operator's existing FAA-approved minimum equipment list (MEL) for the air data/inertial reference system, 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.
Airworthiness Directives; De Havilland Aircraft of Canada Limited (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain De Havilland Aircraft of Canada Limited Model DHC-8-401 and - 402 airplanes. This AD was prompted by reports of loss of hydraulic fluid and annunciation of the check fire detect light. This AD requires doing a detailed visual inspection for chafing and proper clearance of the left-hand (LH) and right-hand (RH) main landing gear (MLG) primary zone advanced pneumatic detector (APD) sensing lines, the hydraulic tube assemblies, and the surrounding structure, and doing all applicable corrective action. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Saab AB, Support and Services (Formerly Known as Saab AB, Saab Aeronautics) Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Saab AB, Support and Services Model SAAB 340B airplanes. This AD was prompted by a report that the circuit breaker for the emergency cabin lighting tripped without fault in the system. This AD requires replacing a certain circuit breaker with a part having a higher rating, 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.
Airworthiness Directives; DG Flugzeugbau GmbH and Schempp-Hirth Flugzeugbau GmbH Gliders
The FAA proposes to adopt a new airworthiness directive (AD) for DG Flugzeugbau GmbH Model DG-1000T gliders and Schempp-Hirth Flugzeugbau GmbH Model Duo Discus T gliders with a Solo Kleinmotoren GmbH Solo Model 2350C or 2350D engine installed. This proposed 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 failure of the bearing of the upper pulley of the belt driven reduction gear resulting in separation of the propeller from the engine. This proposed AD would require replacing a certain hex-nut and would establish a lift limit for the ball bearing assembly. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; True Flight Holdings LLC Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all True Flight Holdings LLC Model AA-1, AA-1A, AA-1B, AA-1C, AA-5, AA-5A, and AA-5B airplanes. This proposed AD was prompted by the report of an accident of an airplane with bondline corrosion and delamination of the horizontal stabilizers. This proposed AD would require inspecting the wings, fuselage, and stabilizers for bondline separation, corrosion, and previous repair. This AD would also require repairing or replacing parts and applying corrosion inhibitor as necessary. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS332L2 and EC225LP helicopters. This proposed AD was prompted by a report of loss of tightening torque on the nut that attaches the tail gear box (TGB) bevel wheel. This proposed AD would require repetitive inspections (measurements) of the angular clearances of the TGB, and, depending on the findings, replacement of the TGB with a serviceable TGB, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). This proposed AD would also provide terminating action for certain repetitive inspections. The FAA is proposing this AD to address the unsafe condition on these products.
