## Discrepancy

SWITCH GUARDS LOCATED ON THE CENTER PEDESTAL DO NOT FUNCTION WELL. A MAIN ENGINE START SWITCH GUARD WAS FOUND PUSHED TO THE SIDE AND PRESSED/JAMMED INTO THE SWITCH CAUSING UNCOMMANDED ACTIVATION WITHOUT LIFTING THE GUARD AND PRESSING THE SWITCH. ANOTHER AIRCRAFT, ALSO LEAR 45, A MAIN ENGINE FIRE EXTINGUISHER SWITCH GUARD WAS FOUND TO PRESS INTO THE SWITCH WHEN THE GUARD WAS NOT ALIGNED CAUSING INADVERTENT ACTIVATION WITHOUT LIFTING THE GUARD AND PRESSING THE SWITCH.
