FAA proposes AD for Boeing 737-8/9/8200 elevator buss assembly bearing inspections

The FAA proposes a new airworthiness directive for certain Boeing 737-8, 737-9, and 737-8200 aircraft due to potential incorrect installation of elevator buss assembly bearings during production, including missing sealant. The directive would mandate detailed inspections for cracks and sealant indications, with on-condition actions. This is a regulatory safety action that could affect airline operations and Boeing's production quality reputation.
