The FAA has finalized a new rule, known as an airworthiness directive (AD), for all Boeing Model 717-200 airplanes due to a report of frozen airspeed indicators during takeoff. The directive requires airlines to modify the air data heat (ADH) system, ensuring correct airspeed is displayed, alongside necessary tests and corrective actions. This step is needed to prevent potential flight safety issues caused by blocked pitot tubes that could lead to a loss of aircraft control. Some industry members supported the rule, while others suggested alternatives, but the FAA decided to implement the proposed measures.
Simple Explanation
The FAA wants all Boeing Model 717-200 airplanes to get a new fix because their speed meters got stuck during takeoff, which could make flying dangerous. They are asking the plane owners to update a part and run tests to make sure everything shows the right speed, even though some people think it might be too expensive.
