The Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) for General Electric Company Model CT7-2E1 engines due to a revised analysis showing that a component, specifically the stage 2 turbine aft cooling plate, has a shorter life than previously thought. This directive requires updating maintenance documents by reducing the life limit for this part from 6,100 cycles to 3,100 cycles to prevent potential failures that could result in severe engine and airplane damage. The rule will take effect on April 17, 2025, and affects eight engines currently used in the U.S.

The Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) for certain MHI RJ Aviation ULC airplanes due to potential interference from 5G wireless broadband operations affecting radio altimeters. This directive mandates the installation of a radio frequency bandpass filter to prevent altimeter anomalies that could lead to unsafe flight conditions, such as overheating issues in the aircraft's hydraulic system or wing structural deformation. The AD follows comments received on its proposal and makes necessary adjustments, including referencing updated service bulletins for compliance. This final rule will help ensure continued safe flight and landing of affected aircraft by requiring timely modifications.

The Federal Aviation Administration (FAA) is proposing a new airworthiness directive (AD) for certain models of Safran Helicopter Engines. This proposal arose from findings that some high-pressure turbine blades might have defects due to manufacturing changes, which could lead to mechanical failures. To prevent this issue, the AD requires replacing the faulty turbine blades as detailed in a European safety agency directive. Interested parties have until April 28, 2025, to provide comments on the proposed rule.

The Federal Aviation Administration (FAA) has released a proposed rule to establish a new airworthiness directive (AD) for several models of Rolls-Royce turbofan engines. This proposed directive is a response to changes made by the manufacturer to the time limits manual (TLM), which now includes repairs for low-pressure compressor (LPC) blades and new fan blade inspections. The goal is to prevent potential engine failure caused by critical rotating parts, which could lead to loss of thrust and control of the aircraft. Stakeholders are invited to comment on the proposal by April 9, 2021.

The Federal Aviation Administration (FAA) has published a supplemental notice of proposed rulemaking (SNPRM) to update and expand previous safety regulations for certain aircraft seat buckle assemblies. This action follows the discovery of additional manufacturing defects involving screws within these buckles, which could fail and potentially endanger passengers. The proposed rule involves inspecting and possibly replacing affected parts and includes options for making certain passenger seats inoperative until repairs are made. The FAA is also inviting public comments on this proposal by March 28, 2025, to ensure comprehensive stakeholder input.

The Federal Aviation Administration (FAA) has proposed a new airworthiness directive for some Rolls-Royce Deutschland BR700 model turbofan engines due to a manufacturing issue that escaped previous detection. This issue affects the disks in the high-pressure turbine of certain engines, which may fail and cause unsafe conditions if not addressed. The directive would mandate the removal and replacement of the affected disks before they reach a specific number of flight cycles or during the next maintenance visit. This proposed action aims to prevent potential damage and maintain aviation safety.

The Federal Aviation Administration (FAA) is proposing a new airworthiness directive for certain Boeing 767 airplane models due to corrosion found on the satellite communications (SATCOM) high gain antenna adapter plates during routine maintenance. This directive would require regular inspections and potential repairs or replacements of the corroded parts to ensure safety. The proposal, available for public comment until June 13, 2025, seeks to prevent parts from detaching during flight, which could lead to significant safety risks.

The Federal Aviation Administration (FAA) has issued a new airworthiness directive for certain Rolls-Royce Deutschland Model Trent XWB-97 engines. This action is due to damage reports concerning the main fuel hose assembly, which may lead to in-flight shutdowns and potential engine fires. To address these concerns, the directive mandates inspections and possible replacements of the damaged components. Public comments on this rule are invited until March 17, 2025, although the rule is set to take effect on February 18, 2025.

The Federal Aviation Administration (FAA) issued a final rule, with corrections, for an airworthiness directive concerning Boeing 737 series airplanes. This rule addresses errors in previously published information related to fan blade out conditions and engine nacelle maintenance on these airplanes. It ensures that the correct specifications are used for maintaining these aircraft to prevent unsafe conditions during flight. The effective date for these corrections remains April 8, 2025, and it does not impose any additional burden on operators.

The Federal Aviation Administration (FAA) is proposing a new airworthiness directive for all Boeing 737-100 to -500 series airplanes. This proposal is due to a reported crack on a specific part of the airplane, which could compromise its structural integrity, potentially causing a fuel leak and fire. The directive requires repetitive inspections and any necessary repairs to ensure the planes' continued safety. The deadline for public comments on this proposal is April 12, 2021.
