Embraer jet doors must be checked for jamming after a sensor failure

The US aviation regulator is ordering new safety checks for all Embraer EMB-545 and EMB-550 airplanes. Operators must now regularly test and lubricate the main door lock sensor mechanism to prevent jamming.

A jammed main door on an aircraft is a serious safety risk. This new rule means that every operator of these specific Embraer jets must add these checks to their maintenance schedule. It shifts the responsibility for preventing this specific failure from a reactive fix to a proactive, mandatory inspection.
