What was found
THE OPERATOR WAS IN THE PROCESS OF UPGRADING THE SOFTWARE FOR THE EFIS-SV SYSTEM IAW SB WSB IDU-III-6. THE NEW DATA WAS LOADED ONTO THE SMART MEDIA CARDS AND THE CARDS WERE THEN INSTALLED IN THE INTEGRATED DISPLAY UNITS (2 EA.) UPON INITIALIZATION OF THE SOFTWARE UPLOAD, THE ENTIRE SYSTEM MALFUNCTIONED AND COULD NOT BE REINITIALIZED. THE AIRCRAFT WAS GROUNDED. AFTER SEVERAL UNSUCCESSFUL ATTEMPTS TO RELOAD THE UPGRADE ONTO THE CARDS AND THEN UPLOAD THE INFORMATION INTO THE SYSTEM, THE SMART MEDIA CARDS WERE REPLACED WITH NEW, THE INFORMATION DOWNLOADED ONTO THE CARDS, AND THE SYSTEM SUCCESSFULLY REBOOTED AND FUNCTIONED PROPERLY.
