    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.

    Simple Explanation

    The FAA has made a new rule to keep certain airplanes safe by updating some important rules they must follow, just like how a car needs regular check-ups to stay safe. These updates will help make sure the planes are strong enough and won't break, and they need to follow these rules by the end of March 2021.

    The Federal Aviation Administration (FAA) has issued a final rule for certain Bombardier airplanes, addressing an issue with the wiring of trim switches that caused uncommanded horizontal stabilizer movements. This directive requires the installation of new trim switch relays to prevent such incidents, which could increase crew workload and potentially lead to loss of airplane control. Affected aircraft must comply with this rule within 3,000 flight hours or five years from March 17, 2025. The directive applies to specific Bombardier aircraft models, and detailed installation instructions are available in the referenced service bulletins.

The new rule addresses reports of uncommanded movements of these seats, which could pose safety risks during critical flight phases. This rule requires inspections and actions based on specific seat part numbers and introduces guidelines for compliance. The FAA has consulted various stakeholders and made some changes based on feedback, ensuring safety without imposing significant economic burdens.

    Simple Explanation

    Imagine the chairs for the pilots on some big Boeing airplanes suddenly moving by themselves; this could be dangerous. The airplane safety people made a new rule to check these chairs so they stay put, like sitting safely in your seatbelt.
