The FAA has issued a final rule requiring inspections for certain Airbus Canada Model BD-500-1A10 and BD-500-1A11 airplanes due to insufficient clearance between fire extinguishing system lines and fasteners, which could lead to a failure in the fire extinguishing system. This rule, effective May 2, 2025, mandates inspections and corrective actions to prevent a possible unsafe condition caused by the fouling of fire extinguishing lines, as outlined in an airworthiness directive from Transport Canada. The FAA addressed comments received during rulemaking and clarified part number corrections and compliance timelines.

The Federal Aviation Administration (FAA) has proposed a new rule for certain International Aero Engines models. This rule addresses a safety issue stemming from fan blade fractures due to bird strikes, which have sometimes led to fires. The proposal requires removing a specific clamp from the fuel tube assembly and replacing the thermal management system clevis mounts. These safety measures aim to prevent future engine fires and aircraft damage. The FAA is seeking public comments on this proposal by May 12, 2025.

The FAA has decided to withdraw a proposed rule that would have applied to Robinson Helicopter Company Model R22 series helicopters. This rule was initially suggested after a helicopter broke apart in-flight due to failed teeter stop brackets. However, the FAA has since determined that the issue was actually due to mast bumping, which is already addressed by a different regulation (AD 95-26-04). As a result, the proposed rule is unnecessary and has been withdrawn.

The Federal Aviation Administration (FAA) has issued a new rule for all Pilatus Aircraft Ltd. Model PC-7 airplanes. This rule addresses an identified unsafe condition concerning a missing screw on a harness shoulder strap buckle that could lead to loss of pilot restraint and potential loss of airplane control or crew injury. Effective February 12, 2021, it requires inspections and potential repairs or replacements of the affected parts to ensure safety. The FAA invites comments on this rule until March 29, 2021, and has deemed the situation urgent enough to forgo the usual public comment period prior to enacting the rule.

The Federal Aviation Administration (FAA) has issued a new rule to address safety concerns related to the emergency escape hatch on certain ATR model airplanes. The rule was prompted by a report that the hatch was difficult to open due to incorrect parts being used. This could impede a flightcrew's ability to evacuate in an emergency. The rule mandates inspections and corrective actions to fix any discrepancies, thereby ensuring these planes are safe for operation.

The FAA is proposing a new airworthiness directive (AD) for certain models of Safran Helicopter Engines. This AD is in response to reports of non-conforming fuel filter pre-blockage pressure switches, which might not activate correctly if there's fuel contamination, potentially leading to engine shutdowns during flight. The proposed rules include routine visual inspections and operational tests of these pressure switches, and replacing them if necessary, to ensure that the engines remain safe to operate. Comments on the proposal are invited by April 8, 2021.

The FAA (Federal Aviation Administration) has proposed a new airworthiness directive for certain MHI RJ Aviation ULC airplanes due to a safety issue with the cockpit voice recorder (CVR) impact switch being installed incorrectly. This incorrect installation could lead to loss of critical data in an accident. The proposed directive requires inspections and corrections to ensure the switch is installed correctly to maintain flight safety. Interested parties have until April 7, 2025, to comment on the proposal.
