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 FAA has issued a new airworthiness directive (AD) for Boeing 727 airplanes due to risks caused by excessive sealant on wing parts, which might hide cracks during inspections. This rule mandates changes to maintenance or inspection programs to ensure the required damage tolerance rating and repetitive inspections of certain wing parts to detect potential issues. Effective March 31, 2021, this AD aims to prevent possible structural failures that could lead to loss of control of the aircraft. The directive includes compliance procedures, costs, and the regulatory rationale behind these safety measures.

The Federal Aviation Administration (FAA) has issued a new airworthiness directive for certain Leonardo helicopter models, specifically AB139 and AW139. This directive mandates the removal of specific engine mounting rods that do not conform to standards and prohibits their installation on any helicopter, as these rods could potentially fail and cause loss of control of the aircraft. The directive is effective from April 1, 2021, and operators are expected to ensure compliance by replacing the non-conforming rods with approved ones. This action was initiated due to a report of non-conforming parts and aims to enhance the safety of these helicopters.

The Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. Model PC-24 airplanes. This directive is a response to information about electrical harness installations that do not meet approved designs, which could cause issues like wire chafing, arcing, or failure. These problems might lead to loss of system redundancy or other safety hazards. To address this, the AD requires modifications to the electrical harness installations, which will cost about $1,775 per aircraft to implement.

The Federal Aviation Administration (FAA) has issued a new rule that affects certain Bombardier BD-700-1A10 airplanes. This rule was prompted by a report of smoke and overheating from emergency light batteries due to corrosion, causing an electrical short. The rule mandates inspections to check the batteries' replacement dates and replacements if necessary, plus updates to the maintenance schedule. The goal is to prevent the risk of fire on these airplanes by ensuring battery-related safety.

The Federal Aviation Administration (FAA) is proposing a new airworthiness directive (AD) for certain General Electric engines used in airplanes. This action is due to concerns about a part called the combustion chamber assembly (CCA) which may fail sooner than expected. To prevent this, the FAA wants regular inspections and timely replacements of this component. They are seeking public comments on this proposal until February 10, 2025.

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 Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) for specific Boeing 737 models due to safety concerns from engine fan blade-out (FBO) events. These incidents caused damage to the aircraft, including cracks in the primary exhaust nozzle. The FAA's directive mandates inspections and modifications, such as the installation of bridge brackets or serviceable nozzles, to ensure safety. Operators must also update their maintenance programs to include new airworthiness limitations to prevent future unsafe conditions.

The Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) for certain aircraft models from Piper and related corporations. This directive was prompted by reports of rudders breaking due to fatigue and corrosion, which could lead to reduced control during flight. The rule requires replacing rudders made with 1025 carbon steel posts with those made from a more durable 4130N low-alloy steel to ensure the safety of these planes. The directive also has an allowance for alternative methods of compliance (AMOCs) if approved by the FAA, giving some flexibility to aircraft operators.

The Federal Aviation Administration (FAA) is proposing changes to the rules governing certain Boeing 767 models. This proposal aims to add more airplanes to the list that require updates to their maintenance or inspection programs with new or stricter airworthiness limitations. These changes aim to address safety issues due to parts that might wear out or fail over time. Because these new rules will impose more requirements compared to earlier proposals, the FAA is reopening the comment period to gather public feedback until April 12, 2021.
