## Discrepancy

ON FRIDAY FEBRUARY 24, 2023 AT APPROXIMATELY 1419 THE CREW DIVERTED TO AIRLIFE 4’S BASE AT THE NEWNAN, GA AIRPORT FOR WEATHER.  DURING THE THREE MINUTE FLIGHT IN MODERATE RAIN, THE CREW NOTICED A COUPLE OF DROPS OF RAIN LEAKING IN NEAR THE ROTOR BREAK HANDLE BEFORE LANDING.

AT APPROXIMATELY 1809 HOURS THE CREW WALKED BACK OUT TO THE HELICOPTER TO RETURN TO BASE.  THE PILOT NOTICED THE UPPER GPS, TRANSPONDER, AND MULTIPLE ANNUNCIATOR LIGHTS ON.  THE CREW COULD SMELL ELECTRICAL BURNING AND COULD HEAR AN ELECTRICAL SURGING SOUND.  THE PILOT CONFIRMED THAT BOTH BATTERY SWITCHES WERE OFF AND CALLED MECHANIC MIKE KENNEDY WHO CONFIRMED THERE WAS NOT A WAY TO QUICK DISCONNECT THE BATTERY TO PREVENT A FIRE.
