Who is responsible for ensuring that tools are procured and issued on a controlled basis?

The correct answer highlights the role of the Material Control Officer, who is primarily responsible for overseeing the procurement, management, and distribution of materials and tools within an organization, particularly in aviation maintenance environments. This position involves ensuring that tools are obtained and issued according to specific controls and procedures, which helps maintain operational readiness and prevent tool loss or misuse.

The responsibilities include tracking inventory levels, placing orders for new tools as needed, and maintaining records of tool usage. The controlled basis aspect signifies that there are systematic processes in place to regulate how tools are accessed and distributed, ensuring accountability and efficiency.

Other roles, such as the Maintenance Officer, Logistics Officer, and Inventory Control Supervisor may have overlapping responsibilities regarding tools and materials, but the Material Control Officer specifically focuses on the controlled issuance and procurement aspects, aligning with the question's requirements.
