## Discrepancy

DURING CRUISE FLIGHT, NOTICED STRONG SMOKE JODOR IN COCKPIT. TURNED OFF ELECTRICAL SYSTEM AND LANDED. EXAMINATION SHOWED THAT THE ESSENTIAL BUSS EMERGENCY BATTERY PACK UNDER CO PILOT PANEL WAS BURNED. FOUND A VERY SMALL SCREW HAD FALLEN FROM SOMEWHERE IN PANEL AND LANDED ON THE CONNECTOR TERMINAL TO THE PACK, SHORTING OUT THE BATTERY PACK. COULD NOT FIND ANY MISSING SCREWS BEHIND PANEL. NOT SURE WHERE THIS CAME FROM.
