The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model H160-B helicopters. This AD was prompted by a report of broken main gearbox (MGB) right hand (RH) center and rear rail support assemblies. This AD requires repetitively inspecting the MGB RH and left hand (LH) center rail support for cracks and, depending on the results of these inspections, accomplishing corrective actions. This AD prohibits the installation of certain part-numbered MGB support assemblies unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is superseding Airworthiness Directive (AD) 2025-11- 10, which applied to Cameron Balloons Ltd. (Cameron) fuel cylinders fitted with certain pressure relief valve (PRV) adaptors on hot air balloons. AD 2025-11-10 required repetitively visually checking the PRV adaptor for cracks and removing any fuel cylinder with a cracked PRV adaptor from service. Since the FAA issued AD 2025-11-10, a new replacement part was introduced into service. This AD retains the repetitive check and removal requirements of AD 2025-11-10 and also requires replacement of the PRV adaptor as terminating action for the repetitive checks. The FAA is issuing this AD to address the unsafe condition on these products.
This interim final rule (IFR) ensures that the U.S. Department of Transportation (DOT or Department) operates its Disadvantaged Business Enterprise (DBE) and Airport Concession Disadvantaged Business Enterprise (ACDBE) Programs (collectively, Programs) in a nondiscriminatory fashion--in line with law and the U.S. Constitution. The IFR removes race- and sex-based presumptions of social and economic disadvantage that violate the U.S. Constitution.
This document announces the acceptance of a means of compliance with FAA regulations for sUA Category 2 and Category 3 operations over human beings. The Administrator finds that AVSS's "Means of Compliance with Sec. Sec. 107.120(a) and 107.130(a) for Small Unmanned Aircraft," revision 6, dated January 7, 2025, provides an acceptable means, but not the only means, of showing compliance with FAA regulations.
This rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPS) and associated Takeoff Minimums and Obstacle Departure procedures (ODPs) for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-200, A330-200 Freighter, A330-300, A340-200, A340-300, A340-500, and A340-600 series airplanes. This AD was prompted by the determination that, during flight with landing gear down, the brake system accumulators and shut-off valve (SOV) protecting the brake accumulators might be exposed to a temperature lower than the one for which the accumulator and SOV are qualified. This AD is also prompted by the determination that, if an airplane is dispatched under existing conditions associated with the "L/G Retraction Fault" alert, operations for Constant Speed Motor/Generator (CSM/G) will be prevented. This AD requires revising the existing airplane flight manual (AFM) to incorporate new procedures for flight with landing gear down and the existing minimum equipment list (MEL) to prevent dispatch with an "L/G Retraction Fault" alert. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is superseding Airworthiness Directive (AD) 2019-12- 13, which applied to all The Boeing Company Model 757 airplanes. AD 2019-12-13 required repetitive checks of the aileron trim actuator bearing for free rotation, repetitive detailed inspections of the aileron trim actuator attachment lug for damage and cracking, and applicable on-condition actions. This AD was prompted by the determination that a modification must be done to address the unsafe condition. This AD retains the actions in AD 2019-12-13. This AD also requires for certain airplanes changing the lateral control box support assembly and installing an aileron trim actuator bracket, and for certain other airplanes replacing the existing actuator lateral control fitting with an aileron trim actuator bracket, which terminates the repetitive checks and inspections. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by a report of improper grinding of the inner diameter of the main landing gear (MLG) outer cylinders, resulting in possible heat damage to the outer cylinders. This AD requires a records check or inspection to determine if an affected outer cylinder is installed and replacing all affected outer cylinders. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for certain ATR--GIE Avions de Transport R[eacute]gional Model ATR42-500 and ATR72 airplanes. This AD was prompted by an investigation indicating that an erroneous monitoring of the travel limitation unit (TLU) could occur when the airplane is flying above a certain speed as a result of the logic input from either air data computer (ADC) 1 or ADC2 input. This AD requires modifying airplanes by installing one or two relays and associated wiring and testing of the TLU monitoring logic. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for certain Textron Aviation Inc. (Textron) Model B200GT, B200CGT, B300, and B300C airplanes. This AD was prompted by a report of rudder control pushrod failure during a production ground run, caused by sheared rivets off of a rudder control pushrod. This AD requires a visual inspection of the attaching rivets of the pilot and copilot rudder control pushrods for incorrect rivets and replacement if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for all Fiberglas-Technik Rudolf Lindner GmbH & Co. KG Model G103 TWIN II, G103A TWIN II ACRO, G103C TWIN III ACRO, and G 103 C TWIN III SL gliders. This AD was prompted by a report of corrosion on the inner sides of the welded steel rudder drive plate. This AD requires repetitive inspections and a one-time detailed inspection of the rudder drive plate for corrosion and water entry and a modification of the rudder drive plate to improve corrosion protection, as applicable. This AD also requires replacement of the rudder if corrosion is found during the inspections that exceed light surface rust. This AD also requires applying additional sealing to the rudder drive plate, which constitutes terminating action for the repetitive inspections. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500- 1A11 airplanes. This AD was prompted by an investigation that showed a change in the feed-through connector O-ring material at a certain frame increased the electrical bonding resistance due to the current torque specification being inadequate. This AD requires electrical bonding tests between the feed-through connectors and the forward side of the bulkhead at a certain frame, and the installation of two electrical bonding plates, as applicable. The FAA is issuing this AD to address the unsafe condition on these products.
