Required Actions

Inspect and repair or replace the close lock torque tube spline, visually inspect the close lock and spring condition, functionally operate the door to ensure proper engagement, and inspect the air storage bottle control valve lever position. Additionally, install specified parts (ABA8023-1/2 slide catches, ABA8024-1/2 stop plates, WBA7003-5/-7 washers) and perform recurring inspections at specified intervals.
