## Discrepancy

DURING RUN-UP FOR FLT, CREW NOTICED WHAT THEY DESCRIBED AS A BURNING ODOR.  NO OTHER ABNORMAL INDICATIONS OBSERVED. ACFT SHUTDOWN NORMALLY, MX WERE NOTIFIED & ACFT WAS TAKEN OOS.  DETAILED INSPECT OF COCKPIT WIRING & ELECT CONNECTIONS CONDUCTED.  ACFT WAS CHARGED FOR APPROX 3 HRS USING CHARGING CART. ACFT WAS RUN AT IDLE FOR 3 MINS,  FLT FOR 3 ADDITIONAL MINUTES.  NO BURNING ODOR WAS NOTICED.  ACFT CLEARED FOR A POST-UNSCHEDULED MAINT FLT.  FLT CONDUCTED & LASTED 13 MINUTES.  ALL ACFT SYS WERE TURNED ON & UTILIZED AS NORMAL THROUGHOUT THE DURATION OF THE 13-MINUTE FLT, NO BURNING ODOR OBSERVED.  ARCT RETURNED TO SERVICE.
