Which document is used to record statistical data during all maintenance on aircraft and subsystems?

The correct choice is the VIDS/MAF, which stands for Vehicle Identification Display System/Maintenance Action Form. This document is specifically designed to record all maintenance activities, including statistical data related to aircraft and subsystems. It serves as a comprehensive record that ensures all maintenance procedures performed on the aircraft are documented thoroughly, thus facilitating tracking of maintenance trends, performance histories, and compliance with regulatory requirements.

The use of VIDS/MAF enables maintenance personnel to manage and communicate maintenance actions effectively, as it captures critical data such as the type of maintenance performed, parts used, and the time taken to complete the work. This information is crucial not only for internal tracking and planning but also for external audits and assessments.

In contrast, other options serve different purposes. The Maintenance Action Form, while the name sounds similar, might not specifically encapsulate all maintenance activities in a statistical format. The Maintenance Status Report typically provides a summary of the current state of aircraft without going into the detailed statistical data of each maintenance activity. The Daily Maintenance Log is mainly used to document daily activities and may not provide the comprehensive statistical overview that VIDS/MAF does.
