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 FAA has issued a new airworthiness directive for specific models of Airbus Helicopters Deutschland GmbH, including EC135 and its variants. This directive requires operators to remove certain Titanium (Ti) bolts, identified by specific part numbers and markings, from service and ban their installation on the forward tail rotor drive shaft. These actions were prompted by safety concerns following a report of a broken Ti-bolt, which could lead to reduced control of the helicopter. The rule is effective as of March 29, 2021, and aims to prevent possible helicopter control issues linked to these Ti-bolts.

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 proposed a new rule aimed at improving safety for certain Boeing 767 airplane models. This is in response to significant changes in limitations related to preventing fuel tank ignition and updating the nitrogen generation system. The proposed rule would require changes to maintenance programs for these aircraft to address potential safety hazards. The FAA is seeking public comments on this proposal by April 12, 2021.

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 that replaces previous directives for certain Airbus SAS airplane models, including the A318, A319, A320, and A321 series. This rule requires operators to update their maintenance or inspection programs to include stricter airworthiness limitations, in order to prevent potential fuel tank explosions. The regulation takes effect on March 21, 2025, and is based on guidelines from the European Union Aviation Safety Agency (EASA). The FAA estimates compliance involves about 90 work-hours per operator.

The Federal Aviation Administration (FAA) has proposed a new airworthiness directive (AD) targeting Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This proposal was prompted by issues with sand and corrosion affecting elevator torque tube bearings, which could potentially hinder airplane pitch control. The AD mandates regular inspections, functional tests, and possible replacements of these parts to avert risks to flight safety. Comments on this proposed directive are due by April 12, 2021.

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) 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 has issued a new rule replacing previous airworthiness directives for ATR72 airplanes. This rule mandates incorporating updated airworthiness limitations to prevent fatigue cracking that could compromise the airplane's structure. The updated limitations are based on European Union Aviation Safety Agency guidelines and apply to certain ATR72 models, excluding those with certificates issued after December 12, 2019. The new requirements must be implemented by March 31, 2021, with specified compliance details and options for alternative approaches.
