McFarlane Throttle Control Vernier-Assist MCVA9863055-10 FAA-PMA Approved

MCVA9863055-10 is a McFarlane Aviation Vernier-Assist™ throttle control assembly for precision throttle adjustment. The control combines friction-based vernier operation with conventional push-pull movement: rotate the knob for fine adjustment and push or pull it for coarse movement.
