The Federal Aviation Administration (FAA) proposes to replace an older Airworthiness Directive (AD) from 2010 for Airbus Helicopters, previously Eurocopter France, Model SA330J helicopters. This new rule aims to improve aircraft safety by requiring an inspection and potential replacement of the main gearbox oil cooling fan rotor shaft bearings with an updated design developed by Airbus. These actions are intended to prevent possible rotor failure, which could lead to damage and loss of control of the helicopter. The FAA is inviting public comments on this proposed rule by April 12, 2021.

The Federal Aviation Administration (FAA) is proposing a new airworthiness directive for certain models of Siam Hiller Holdings, Inc. helicopters. This proposal is due to reports of cracks in the main rotor transmission drive shaft that could result in dangerous conditions. The directive requires inspecting specific drive shafts for cracks, prohibits installing uninspected drive shafts, and restricts the use of certain paint removers. The FAA has invited public comments on this proposal, highlighting the importance of addressing these safety concerns.

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) is updating a previous safety directive for certain Airbus Helicopters, specifically Model SA330J, to address issues with the tail rotor blades. This update requires more frequent inspections and clarifies the compliance procedures. The purpose of these changes is to reduce the risk of fatigue cracks which could lead to a failure of the tail rotor blade and, consequently, loss of control of the helicopter. Helicopters must regularly undergo inspections and any rotor blades showing issues must be repaired or replaced before they can be used again.

The Federal Aviation Administration (FAA) has issued a new rule for certain Airbus Helicopters Deutschland GmbH models to address issues with malfunctioning emergency fuel shut-off switches. This rule requires inspections of these switches and, if necessary, repairs or replacements to prevent potential in-flight engine shutdowns. The urgency of this safety measure means it's effective from March 24, 2025, with some compliance actions required within a limited timeframe. The FAA invites public comments on this rule until April 21, 2025, and further details can be found through official resources like regulations.gov.

The Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) for all Airbus Helicopters Model EC225LP helicopters due to a reported crack in the main rotor hub (MRH) sleeve. This directive requires regular inspections of certain MRH sleeves and restricts the installation of these sleeves unless they meet inspection requirements based on a European Union Aviation Safety Agency (EASA) directive. The FAA aims to address this unsafe condition, as failing to manage it could lead to major structural failures and loss of control of the helicopter. The FAA is accepting comments on this final rule until January 21, 2025, and the rule becomes effective on December 20, 2024.

The Federal Aviation Administration (FAA) has issued a final rule regarding a new airworthiness directive (AD) for Leonardo AW189 helicopters. This directive is a response to reports of failures in the main rotor (MR) damper, which, if not fixed, could result in severe helicopter control issues. The rule mandates regular inspections and replacements of the MR dampers, along with other checks to prevent unsafe conditions. The new rule takes effect on April 1, 2021, and aims to ensure these helicopters remain safe to operate.

The Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) for various models of Airbus Helicopters due to concerns about engine compartment fires linked to aluminum firewall stiffeners. This rule requires replacing the aluminum stiffeners with titanium ones, as they are better at handling high temperatures. The directive, effective April 11, 2025, aims to prevent engine fires from spreading and potentially causing a loss of control of the helicopter. The rule assumes a cost for compliance, including labor and parts, and affects 35 helicopters registered in the U.S.

The Federal Aviation Administration (FAA) is proposing to update an existing Airworthiness Directive for Robinson Helicopter Company's R44 and R44 II models. This proposed rule aims to clarify inspections of certain parts due to potential fatigue cracking that could lead to loss of control. The FAA seeks public comments by March 17, 2025, and estimates the inspection and potential replacement efforts will impact 1,725 helicopters. The rule ensures the safety of these helicopters by improving maintenance procedures.

The Federal Aviation Administration (FAA) is proposing a new airworthiness directive for certain Airbus Helicopters models due to reports of significant wear in specific parts of the helicopter. This proposal requires measuring wear in these parts and taking corrective actions based on the results. The proposal also includes a prohibition on installing certain parts unless specific conditions are met. The directive aims to address safety concerns and ensure the continued safe operation of these helicopters.
