The Federal Aviation Administration (FAA) has announced a proposed airworthiness directive targeting the Boeing 737 MAX series after identifying a potentially hazardous wiring issue affecting the aircraft’s wing spoilers. This issue, stemming from improperly installed spoiler wire bundles, has been linked to unexpected in-flight maneuvers, including uncommanded rolls, which could compromise pilots’ ability to maintain control.
The directive comes in response to incidents of non-standard installations of these wire bundles, notably leading to at least one instance where a spoiler became completely jammed in its fully extended position—a condition known as a “hardover.” Spoilers, critical for controlling the plane’s lift and drag by disrupting airflow over the wings, when jammed, can significantly impact the aircraft’s stability and maneuverability.
This move by the FAA underscores the ongoing scrutiny of the 737 MAX’s safety systems and procedures, highlighting the imperative for stringent oversight and prompt correction of identified issues to ensure the safety of flights operating with this aircraft model.
