What was found
WHEN THE PILOTS CONTROL COLUMN WAS PULLED AFT AND ROTATED, THE AILERON CABLE TURNBUCKLES AND ASSOCIATED HARDWARE CHAFED AGAINST A WIRE BUNDLE FORWARD OF THE INSTRUMENT PANEL. THIS CAUSED TWO WIRES FROM THAT BUNDLE TO SHORT OUT AND BREAK, THUS RESULTING IN SPARKS COMING FROM UNDER THE INSTRUMENT PANEL. BOTH FUEL QUANTITY INDICATORS IMMEDIATELY LOST POWER AND WENT TO ZERO.
