## Discrepancy

STARTER/GENERATOR WAS PURCHASED FROM DEHAVILLAND ZERO TIME NEW.  AFTER 1211.5 FLIGHT HOURS OF OPERATION, STARTER/GENERATOR FAILED.  TEAR DOWN REVEALED INSULATORS WERE MISSING FROM THE BRUSH HOLDERS.  THIS CAUSED THE ARMATURE AND STATOR TO SHORT CIRCUIT RESULTING IN STARTER/GENERATOR FAILURE.
