To this point the operator has completed the PMCS
inspection and has given the DA Form 5988-E to the immediate
supervisor. The next step is to get the maintenance supervisor to
send a mechanic to look at the vehicle.
Since the vehicle has an NMC fault, the maintenance supervisor should send a mechanic immediately to
diagnose the equipment faults for corrective action. The unit SOP must specify the amount of
time allowed from the time an operator reports an NMC fault to the time that unit
maintenance takes corrective action. Corrective action is when a repair part has been
requested or when a job order has been submitted.
The time between fault identification and the time of correction is a major concern
because many units fail to meet unit SOP requirements. This not only lowers the unit
readiness rate, but causes operators to lose confidence in the unit maintenance operations.
In most units, the SOP requires that corrective action be taken within 24 hours from the
fault date for NMC faults.
The mechanic will attempt to repair the faults using the unit's on-hand
assets. Let's assume that in this case the mechanic will need to order repair parts to fix
the equipment faults. This means that the TM -20P will be used to identify the required parts to repair the reported
faults. These two steps, diagnosing the problem and requesting repair parts, must be closely
monitored. The maintenance supervisor's first priority is to check the mechanic's work on
NMC fault diagnosis and
NMC request for parts. As time allows, the maintenance supervisor should also check all
other fault diagnoses and corrective actions.
Assume that the mechanic has checked the three faults and decided that three
parts are needed:
A transmitter for the temperature gage.
A high beam switch for the headlights.
A seat cushion for the driver's seat.
Now the mechanic must locate the national item identification number (NIIN) in the parts TM. Keep in mind that D2 is an M113A2
armored personnel carrier. This information is critical in providing accurate repair parts
data.
