The Federal Aviation Administration (FAA) has issued a new rule for certain Boeing 737-700 airplanes. This rule requires repeated testing to ensure the correct functioning of specific systems that help clear smoke and manage air pressure, along with additional measures like installing new relays and rewiring. The rule aims to prevent potential safety issues like smoke in the cockpit and loss of aircraft control in the event of a fire. The FAA encourages the public to submit comments on this rule by April 8, 2021.
Simple Explanation
The FAA made a new rule for some Boeing airplanes to check if their smoke and air systems work right. They want to make sure it's safe if something goes wrong, like a fire, and they want people to say what they think about this rule.
