How do I get the access of the parent component or root parent in Unity3d C#

I am having a problem applying damage to the enemy ai . The health2016 script is the enemy ai health script . I need to get access of the parent in the shootable script from the health2016 script or root parent. So I can apply damage to the enemy ai . The amount of damage is already set in the shootable weapon script. I don't know how to code that in my health2016 script. In the Hitscan fire function its Health hit. Health hit is a networking health script and don't want to use that. I did change health hit to health2016 and apply damage to enemy ai and weapon still didn't do any damage . So I change the code back to health hit. So gotta keep it coded health hit. I am making networking game. I just need to access the parent in the hitscan fire function from health2016 , so I can apply damage to enemy ai.

using UnityEngine; using System.Collections;

public class health2016 : MonoBehaviour { public int Health;

 void Start () {
 
 }
 

 public void TakeDamage (int amount) {
  Health -= amount;
 }

}

using UnityEngine;

namespace Opsive.ThirdPersonController { ///

/// Any weapon that can be shot. This includes pistols, rocket launchers, bow and arrows, etc. /// public class ShootableWeapon : Weapon, IFlashlightUsable, ILaserSightUsable {

private void HitscanFire() { // Cast a ray between the fire point and the position found by the crosshairs camera ray. var fireDirection = FireDirection(); if (Physics.Raycast(m_FirePoint.position, fireDirection, out m_RaycastHit, m_FireRange, m_HitscanImpactLayers.value)) {

             // Execute any custom events.
             if (!string.IsNullOrEmpty(m_HitscanDamageEvent)) {
                 EventHandler.ExecuteEvent(m_RaycastHit.collider.gameObject, m_HitscanDamageEvent, m_HitscanDamageAmount, m_RaycastHit.point, m_RaycastHit.normal * -m_HitscanImpactForce);
             }

             // If the Health component exists it will apply a force to the rigidbody in addition to deducting the health. Otherwise just apply the force to the rigidbody. 
             Health hitHealth;
             if ((hitHealth = m_RaycastHit.transform.GetComponentInParent<Health>()) != null) {
                 hitHealth.Damage(m_HitscanDamageAmount, m_RaycastHit.point, fireDirection * m_HitscanImpactForce, m_Character);
             } else if (m_HitscanImpactForce > 0 && m_RaycastHit.rigidbody != null && !m_RaycastHit.rigidbody.isKinematic) {
                 m_RaycastHit.rigidbody.AddForceAtPosition(fireDirection * m_HitscanImpactForce, m_RaycastHit.point);
             }
