What should you do with the STAB TRIM DISC to address runaway trim?

• A. Push, hold, and release
• B. Spin clockwise
• C. Pull and hold
• D. Push and immediately release without hold

Answer: (A)

When trim goes runaway, you need to interrupt the trim system to stop the motor and regain manual control. The STAB TRIM DISC is a momentary interrupt switch, so pushing it in and holding it cuts power to the trim motor. Keep holding until the stabilizer stops moving, then release. This ensures the system is truly disengaged and won’t resume trimming on its own. Simply releasing right away or using a different action won’t reliably interrupt the runaway, and attempting to pull or spin in a direction won’t address the fault. After the motion has stopped, you can manage control and follow further checklist steps as needed.
