The Federal Aviation Administration (FAA) has issued a new rule replacing a previous Airworthiness Directive (AD) concerning specific models of Leonardo S.p.A. helicopters. This new AD requires ongoing inspections and maintenance of the tail rotor duplex bearing to ensure the safety and stability of the aircraft. The rule, effective April 1, 2021, anticipates monitoring for any unsafe conditions in these helicopters due to incorrect installations that could lead to loss of control. It sets forth clear procedures operators must follow to comply with these requirements, including removing specific parts if defects are found.

The Federal Aviation Administration (FAA) has issued a final rule concerning certain Boeing 747 models. This rule was prompted by an incident where water leaks during servicing led to warning messages from the airplane's systems, caused by the detachment of a fitting and steel water tube. To address the problem, the rule requires installing protective components on water supply lines to prevent future leaks that could affect electronics crucial for safe flight. This directive will be effective from March 21, 2025, and aims to ensure the continued safety of these aircraft.

The FAA has proposed a rule regarding airworthiness directives for certain ATR42-500 airplanes. This new rule seeks to update and replace existing directives due to identified safety concerns, imposing stricter airworthiness limitations to ensure these airplanes' structural integrity. The proposed changes require revisions to maintenance and inspection programs and open a comment period for the public until April 12, 2021. The rule also outlines anticipated costs for the operators and provides exceptions to some requirements from related European regulations.

The FAA has issued a new Airworthiness Directive (AD) that updates previous requirements for Rolls-Royce Trent7000-72 and Trent7000-72C engines. This rule comes after the manufacturer updated its maintenance manual to include stricter inspection tasks and time limits for engine parts that have a limited lifespan. The goal of the directive is to prevent engine failures that could potentially lead to loss of aircraft control. Compliance with this AD will become mandatory starting April 17, 2025.

The FAA proposes a new rule for certain models of Airbus Helicopters to address reports of flexible couplings that are breaking or becoming deformed, which could reduce helicopter control. This rule requires inspecting and, if necessary, replacing parts of the tail rotor driveshaft. The FAA is working with the European Union Aviation Safety Agency to address this safety issue and is asking for public comments by June 9, 2025. The rule outlines specific compliance steps for ensuring safety, including adapting from EASA's guidelines and incorporating them into U.S. regulations.

The FAA is introducing a proposed rule to implement a new airworthiness directive for Deutsche Aircraft GmbH Model 328-100 and Model 328-300 airplanes. This action is motivated by discovered cracks in the nose landing gear uplock bracket assembly, which pose a safety risk. The directive mandates an inspection of the affected parts and necessary follow-up actions as detailed in a related European Union Aviation Safety Agency directive. The FAA is seeking comments on this proposal by February 10, 2025, to ensure it addresses the potential for an unsafe condition in these aircraft.

The Federal Aviation Administration (FAA) has proposed a new rule to replace an existing Airworthiness Directive (AD) for specific GE Aviation Czech engines. This rule is aimed at addressing an unsafe condition caused by improper welding that may lead to cracks in the engine's centrifugal compressor case. The new directive requires repeated inspections and potential replacement of compressor cases if cracks are found, aligning with an European Union Aviation Safety Agency (EASA) directive. Public comments on this proposal are invited by June 9, 2025.

The Federal Aviation Administration (FAA) has proposed a new airworthiness directive for Saab AB Model SAAB 2000 airplanes, following a report of the main landing gear collapsing after landing. This would require modifying the hydraulic transfer valve to prevent further unsafe conditions that could lead to severe damage or injury. The proposed rule is based on a directive from the European Union Aviation Safety Agency and aims to ensure the aircraft's safe operation. Interested parties have until April 12, 2021, to submit comments on the proposed rule.

The Federal Aviation Administration (FAA) proposed a new rule to replace a previous airworthiness directive (AD) related to certain Bombardier, Inc. airplanes, specifically models in the CL-600 series. The initial AD had called for inspections and possible modifications to the portable oxygen bottle installations to ensure they could be quickly accessed in emergencies. The new proposal aims to expand the scope to include additional airplanes identified as having the same safety concern. The FAA invites comments on this rule by February 14, 2025, and provides procedures for submitting feedback.

The FAA has issued a new airworthiness directive (AD) for certain Bell Textron Canada Limited Model 505 helicopters to address a safety risk involving deformation in the door hinge of the ballast box assembly, which could lead to dangerous scenarios during flight. This directive requires the removal of all ballast weights from the affected parts and prohibits their use to prevent possible damage to the tail rotor which might result in loss of control over the aircraft. Public comments on this directive are invited until May 27, 2025, while compliance with the directive is required by April 25, 2025. This AD incorporates instructions from a Transport Canada emergency directive and aims to ensure safe flight operations.
