The various embodiments herein provide a coaxial hydraulic actuator assembly for an aircraft hydraulic system for providing the dual redundancy operations in normal and emergency operations. The embodiments herein adopt a coaxial hydraulic cylinder based actuator system comprising a conventional fixed cylinder with a moving piston actuator. The fixed cylinder with a moving piston actuator is located in a first region. The fixed cylinder with the moving piston actuator is manufactured in tandem with a moving cylinder with fixed piston actuator. The moving cylinder with a fixed piston actuator is located in a second region. The fixed piston actuator in the second region is also referred to as actuation rod. Further, the coaxial hydraulic cylinder based actuator system comprises a first adapter and a first cap for the first region. Similarly, a second adapter and a second cap are provided for the second region.
