6.5  Process average.  Sampling may be initiated if the process average value for the first ten vehicles inspected is less than the AQL specified in the classification of defects for major and minor defects.

Process average  =               Number of defects           x 100

Number of vehicles inspected

If the computed process average exceeds the specified AQL, 100 percent inspection shall be performed and continued until such time that the process average for ten consecutive vehicles is less than the specified AQL.

6.6  Definitions.  The following definitions shall be used with the classification of defects for leaks:

a.   Weep:        Any evidence of fluid beyond the seal.

b.   Seep:         Any evidence of fluid beyond the seal that does not result in formation of a droplet.

c.   Droplet:     Any evidence of fluid beyond the seal that results in the formation of a droplet.

d.   Drip:          Any evidence of fluid beyond the seal where droplet forms and falls. e.   Leak:         A steady series of drips.

f.    Excessive

leak:         A steady stream of fluid.

6.7  Deficiency sheet.  The Government inspector shall verify that a thorough inspection of each vehicle is performed by the contractor for the listed characteristics, and for any departures from good workmanship.  The Government inspector shall assure that all defects encountered during inspection are enumerated on a deficiency sheet for the vehicle.  Defects noted on a deficiency sheet shall contain sufficient description to enable the Government inspector and the contractor's representative to classify the defects in accordance with the classification of defects (see table IV) definitions contained in MIL-STD-105.  Corrective action shall be taken for recurring defects.

6.7.1  Recurring major defects.  A major defect is recurring when the same defect occurs more than once in the same sample, or when the defect occurs in two successive samples.  A major defect may be considered recurring when the historical inspection records ("P" chart or equivalent) reflect such a condition.  Recurring major defects shall be cause for the entire lot or lots to be inspected for the recurring defects.

6.7.2  Recurring minor defects.  A minor defect is recurring if it occurs more than twice in the same sample or when the defect occurs in four successive samples.  Recurring minor defects shall be cause for the entire lot or lots to be inspected for the recurring defects.
