SUPPORTABILITY ANALYSES
| 1. | Maintenance Task Analysis (MTA) | | |
| 1.1 | Introduction: | The Maintenance Task Analysis is the identification of the steps, spares and materials, tools, support equipment, personnel skill levels and facility issues that must be considered for a given repair task. It also includes the elapsed time required for the performance of each maintenance task. MTA’s cover both corrective and preventative maintenance tasks, and when complete, identify all physical resources required to support the system. The MTA and shall be used to provide input to generate the Maintenance Allocation Chart (MAC). |
| 1.2 | Requirements: | | The Contractor will perform a MTA for the {End Item Name}. The analysis will be conducted, documented, and submitted using the Microsoft Excel template provided (see attachment 1) and contain elements and coding information contained in Table I-V below: |
| a. | In End Item hardware top-down-breakdown sequence. |
| b. | All preventive and corrective maintenance actions shall be identified. |
| c. | All spares and support equipment required to perform each maintenance task. |
| d. | All tasks, tools recommended for training will be identified. |

Table III
| Maintenance Function |
| Task Action Code |
| Definition |
| Inspect |
| A |
| To determine the serviceability of an item by comparing its physical, mechanical, and/or electrical characteristics with established standards through examination (e.g., by sight, sound, or feel). This includes scheduled inspection and gauging’s and evaluation of cannon tubes. |
| Test |
| B |
| To verify serviceability by measuring the mechanical, pneumatic, hydraulic, or electrical characteristics of an item and comparing those characteristics with prescribed standards on a scheduled basis, i.e., load testing of lift devices and hydrostatic testing of pressure hoses. |
| Service |
| C |
| Operations required periodically to keep an item in proper operating condition; e.g., to clean (includes decontaminate, when required), to preserve, to drain, to paint, or to replenish fuel, lubricants, chemical fluids, or gases. This includes scheduled exercising and purging of recoil mechanisms. The following are examples of service functions: |
a. Unpack. To remove from packing box for service or when required for the performance of maintenance operations.
b. Repack. To return item to packing box after service and other maintenance operations.
c. Clean. To rid the item of contamination.
d. Touch up. To spot paint scratched or blistered surfaces.
e. Mark. To restore obliterated identification.
| Adjust |
| D |
| To maintain or regulate, within prescribed limits, by bringing into proper position, or by setting the operating characteristics to specified parameters. |
| Align |
| E |
| To adjust specified variable elements of an item to bring about optimum or desired performance. |
| Calibrate |
| F |
| To determine and cause corrections to be made or to be adjusted on instruments of test, measuring, and diagnostic equipment used in precision measurement. Consists of comparisons of two instruments, one of which is a certified standard of known accuracy, to detect and adjust any discrepancy in the accuracy of the instrument being compared. |
| Remove/Install |
| G |
| To remove and install the same item when required to perform service or other maintenance functions. Install may be the act of emplacing, seating, or fixing into position a spare, repair part, or module (component or assembly) in a manner to allow the proper functioning of an equipment or system. |
| Replace |
| H |
| To remove an unserviceable item and install a serviceable counterpart in its place. “Replace” is authorized by the MAC and assigned maintenance level is shown as the third position code of the Source, Maintenance, Recoverability (SMR) code. |
| Repair |
| J |
| The application of maintenance services, including fault |
location/troubleshooting, removal/installation, disassembly/assembly procedures and maintenance actions to identify troubles and restore serviceability to an item by correcting specific damage, fault, malfunction, or failure in a part, subassembly, module (component or assembly), end item, or system.
| Overhaul |
| K |
| That maintenance effort (service/action) prescribed to restore an item to a completely serviceable/operational condition as required by maintenance standards in appropriate technical publications. Overhaul is normally the highest degree of maintenance performed by the Army. Overhaul does not normally return an item to like new condition. |
| Rebuild |
| R |
| Consists of those services/actions necessary for the restoration of unserviceable equipment to a like new condition in accordance with original manufacturing standards. Rebuild is the highest degree of material maintenance applied to Army equipment. The rebuild operation includes the act of returning to zero those age measurements (e.g., hours/miles) considered in classifying Army equipment/components. |
