The Federal Aviation Administration has issued a new safety mandate for the Boeing 737 Max fleet due to a technical flaw that causes aircraft interiors to reach dangerous temperatures.
This issue stems from tripped circuit breakers that inadvertently close air intake doors, preventing the cooling of hot engine air before it enters the cockpit and cabin.
To mitigate this risk, flight crews are now required to follow emergency checklists that include descending to lower altitudes and resetting specific electrical switches.
This directive expands upon a previous safety order and impacts over 800 aircraft currently operating in the United States.
While these manual procedures serve as a temporary fix, Boeing is reportedly working on a permanent engineering solution to prevent these electrical malfunctions
. These regulatory actions were triggered by multiple in-flight incidents where pilots lost control of the onboard climate systems.
