What program is used for recording applicability of technical Directives?

The correct answer is the Technical Directive Management System (TDMS), which is specifically designed for tracking and managing the applicability of technical directives. This system serves as a comprehensive database that ensures that personnel are aware of and compliant with the latest technical orders, ensuring that maintenance and operational procedures adhere to current standards.

Using TDMS allows for a streamlined method of documenting the applicability of various technical directives, making it easier for maintenance personnel to determine what directives affect their specific aircraft or equipment. This tracking capability is crucial for maintaining safety and operational readiness in the aviation field.

While the other systems may have relevant functions within the realm of aviation maintenance and documentation, they do not specifically focus on tracking technical directives in the same organized and centralized manner as TDMS. The Designated Management System plays a key role in connecting technical directives to the aircraft or systems they pertain to, ensuring clarity and accountability within maintenance procedures.
