## Discrepancy

STARTER GEN PREVIOUSLY HAD A FIELD FAILURE-COMPLETE MELT DOWN AFTER APPROX 12 FLIGHTS AFTER OVERHAUL.  IT WAS REPAIRED UNDER WARRANTY AND REINSTALLED.  AFTER APPROX 4 FLIGHTS IT WOULD NOT CONSISTENTLY CARRY THE LOAD.  ACFT REGULATION/CHARGING SYST CHECKED AND FOUND CORRECT.  THE INSP COVER ON THE GENERATOR WAS REMOVED AND DAMAGE TO THE COMMUTATOR WAS FOUND PROBABLY DUE TO THE PREVIOUS FAILURE.  INSP OF 1 SET OF BRUSHES REVEALED GROOVED FACES AND THE LACK OF PROPER BRUSH RUN AT OVERHAUL.  AS STATED THIS IS 2ND FAILURE OF THIS ITEM IN A VERY SHORT TIME, THESE FAILURES ARE OBVIOUSLY DUE TO THE LACK OF PROPER PROCEDURES/ WORKMANSHIP BEING FOLLOWED.  (K)
