升降舵与水平安定面同时失去控制原因？

不可能的，除非elevator neutral shift rods完全卡死，
“The elevator neutral shift rods are pogo type control rods with a
spring inside. When the stabilizer moves, it moves the two
elevator neutral shift rods. The neutral shift rods move a torque
tube and crank assembly which moves the mach trim actuator.
When the mach trim actuator moves because of the neutral shift
rod input, it acts as a link and turns the elevator feel and
centering unit housing. This creates a new neutral position for
the elevators.
Each rod also provides protection, in both directions (push or
pull) if there is jam between the stabilizer and the elevator feel
and centering unit. The pilot must supply approximately 180
pounds of additional force to extend or compress the springs
inside the rods. The breakout force of each rod is 90 pounds”
