The Federal Aviation Administration (FAA) has proposed a new airworthiness directive (AD) for specific Bombardier Model BD-100-1A10 airplanes due to DC motor pump (DCMP) failures that occurred during production flight tests. This proposed AD would require installing a redesigned DCMP electric motor assembly to prevent disconnection of electrical system generators caused by excessive voltage. Comments on this proposal are welcome until April 12, 2021, and the FAA aims to address the unsafe conditions in these airplanes with this directive.

The Federal Aviation Administration (FAA) has proposed a new rule concerning Airbus Canada Limited Partnership aircraft models BD-500-1A10 and BD-500-1A11. This proposed rule is in response to a design review that identified a problem with the software protection logic related to engine bleed duct leaks, which could lead to a dual engine failure. The proposal requires changes to the airplane flight manual to ensure that flight crews can manually isolate the opposite engine in case of a large leak. Comments on this proposal are requested by January 27, 2025, to address the identified safety issue effectively.

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 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 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) is proposing a new rule to inspect certain Boeing 767 airplanes for cracks in specific areas, due to a discovered defect at a fastener hole. This rule, part of an Airworthiness Directive (AD), requires owners to conduct inspections and make any necessary repairs to avoid compromising the planes' structural integrity. The rule aims to ensure safety by addressing potential issues before they become serious. Comments on this proposal are invited until May 27, 2025.

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 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.

The Federal Aviation Administration (FAA) has proposed a new airworthiness directive (AD) for specific models of ATR72 airplanes. This AD aims to incorporate updated safety requirements from the European Union Aviation Safety Agency (EASA) by revising current maintenance or inspection programs. It addresses a potential safety hazard where the chemical oxygen mask release system might fail, possibly endangering passengers and crew. Feedback on this proposal is invited from the public until April 10, 2025.

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.
