The MLHs expended at each unit for ACMS tracked MPCs and the EAL maintenance and servicing forms are approximately what percent for the total maintenance labor hours expended?

• A. 85%
• B. 75%
• C. 90%
• D. 60%

Answer: (A)

The main idea is how maintenance time is distributed, specifically the portion of labor hours allocated to the manual labor hours (MLH) at each unit for the ACMS tracked MPCs and the EAL maintenance and servicing forms. These tasks involve routine, scheduled work—calibration, checks, troubleshooting, and the necessary paperwork to document that work in the EAL system. Because these activities are performed regularly and across units, they dominate the workload. The data show that this MLH portion accounts for about 85 percent of the total maintenance labor hours, making it the large majority of the effort. The remaining hours cover other maintenance tasks, such as non-ACMS equipment work, unscheduled repairs, and administrative duties. So, about 85% best reflects the share of total maintenance labor hours devoted to these tracked MPC maintenance and EAL servicing activities.
