Which consequence results when a tail rotor's collective pitch control fails in a helicopter?

💡 Explanation

When collective pitch control fails, the tail rotor thrust cannot be adjusted; because the mechanical linkage is broken, uncontrolled yaw rotation commences due to main rotor torque. Therefore, a spin occurs rather than stabilized flight, due rotor compensating action being lost.
