ACFT EQUIP PROB CREATES A DIVERSION TO ALTERNATE WHEN ALTERNATE LNDG CHARTS ARE NOT AVAILABLE IN ACFT.

Narrative

DURING THIS FLT; WITH AN FAA INSPECTOR ON OUR JUMPSEAT; MY FO AND MYSELF HAD A MECHANICAL PROB WITH OUR FLAPS AND HAD TO PERFORM A FLAPS UP LNDG. THE 2 LNDG DISTANCE CHARTS THAT ARE REQUIRED TO BE IN THE ACFT; PROVIDED BY THE COMPANY IN THE COMPANY FLT MANUAL; WERE MISSING. THE ACFT I FLY IS AN E120 BRASILIA. UPON 2/3 COMPLETION OF THE FLT WHILE STILL IN CRUISE FLT; WE RECEIVED A WARNING ON OUR ANNUNCIATOR PANEL INDICATING A 'CTL FAULT' IN OUR FLAP SYS. I PICKED UP OUR QUICK REACTION HANDBOOK TO REMEDY THE SIT. WE COMPLIED WITH THE QUICK REACTION HANDBOOK (QRH) BUT COULD NOT CLR THE CTL FAULT DEEMING OUR FLAPS UNUSABLE AND STUCK IN THE '0' DEG POS. I DETERMINED OUR LNDG REF SPD USING THE QRH AND WAS REQUIRED TO INCREASE THE LNDG DISTANCE 73 PERCENT. THE COMPANY FLTS MANUAL IS ISSUED TO THE ACFT AND IS REQUIRED TO CONSIST OF ALL PERFORMANCE CHARTS NEEDED FOR OUR ACFT. I WAS UNABLE TO LOCATE EITHER OF THE 2 LNDG DISTANCE CHARTS. AS I PLACED THE COMPANY FLTS MANUAL DOWN BESIDE ME TO THINK OF ANOTHER PLACE IN THE COCKPIT THE CHARTS COULD BE LOCATED; THE INSPECTOR ASKED IF I HAD ENOUGH RWY TO LAND AT THE DEST ARPT INCLUDING THE 73 PERCENT. I SAID I DON'T KNOW. I THEN THUMBED THROUGH THE BOOK A SECOND TIME SHOWING THE INSPECTOR AND THE FO THAT THERE WAS NO SUCH CHART. I CALLED THE COMPANY ON THE RADIO TO GET INFO FROM OUR CHIEF PLT. WE HELD NEAR OUR DESTINATION WHILE WAITING. WITH NO ANSWER FROM THE COMPANY AND CONSIDERING OUR RESERVE FUEL; WE CHOSE TO LAND AT AN ARPT 5 MINS AWAY AND WHOSE LENGTH EXCEEDED OUR ORIGINAL ARPT'S LENGTH BY 5000 FT FOR A TOTAL LNDG DISTANCE OF 12000 FT. PERHAPS IF THE COMPANY REQUIRED EACH INDIVIDUAL PLT TO CARRY THEIR REQUIRED CHARTS INSTEAD OF ISSUING THEM TO THE ACFT WE COULD BE RESPONSIBLE FOR OUR OWN.
