## Discrepancy

DURING A ROUTINE VFR TRAINING FLIGHT, THE CREW NOTICED A STRONG ODOR OF AN ELECTRICAL BURN.  THE AIRCRAFT ELECTRICAL SYSTEM WAS TURNED OFF AND A LANDING MADE WITHOUT INCIDENT.  FAILURE OF THE G2 COMPASS AMPLIFIER WAS FOUND TO BE THE SOURCE.  THE TRANSFORMER CONTAINED WITHIN HARD THERMAL DAMAGE INDICATED.  NO DAMAGE TO AIRCRAFT STRUCTURE.
