Maintenance Task Analysis (MTA)

ALCL 079
Alternate Definition

MTA is the identification of the steps, spares and materials, tools, support equipment, personnel skill levels as well as any facility issues that must be considered for a given repair task. Also included in the MTA are elapsed times required for the performance of each task. MTAs cover both corrective and preventative maintenance tasks and, when complete, identify all physical resources required to support a system.

General Information

Performing an MTA begins with identifying each step of the repair process. The steps are analyzed, and a description written as to how they would be physically performed. After the description, resources to perform that task are identified. These resources include:

  • Person or persons participating in each step including a narrative description of what they are doing
  • Time duration of each person’s participation
  • Tools or support equipment required
  • Parts and materials needed for the step

Once the above activities are complete, the results are analyzed to determine the following:

  • The total elapsed time for the task; start to completion
  • The skill level of the person (or persons) required to perform the task based on their minimum technical capabilities, knowledge and experience
  • Any additional training that must be provided to ensure proper task performance
  • Any facility implications such as space limitations, environmental controls, health hazards or minimum capacity requirements

Finally, the MTA results must be analyzed to assess the items compliance with all supportability issues such as ease of maintenance or accessibility and standardization that may have been established by earlier analytical tools or functional analyses. The source for comparison of the physical support requirements for acceptability should be the requirements documents (i.e., the Initial Capability Description (ICD)Capabilility Development Document (CDD), etc.) Many of these design limitations may be derived from actual state requirements. Any shortfalls or noncompliant features must be reported back to the design organization (vendor) for correction. This closes the loop between requirements for the design and the actual results of the design process.
