The FAA Special Airworthiness Information Bulletin SAIB: NM-15-03 addresses an airworthiness concern regarding inadvertent actuation of flight deck controls on all Boeing transport category airplanes, specifically highlighting the Boeing 737-700 and 737-500 models. The bulletin informs operators about the risk of confusing the rudder trim switch with the flight deck door control switch, which can lead to unintended aircraft control inputs during flight.
