Narrative: We had just taken off and climbing through 11;500 ft I saw the FMS1 warning light on the PDF flashing red.  I looked down to see both FMS's with GPS position lost on them.  I looked up to see both PDF's an ND's go blank.  Shortly after that the cockpit went dark with only a faint glow from the standby instruments. We only had the number 1 radio for a time than we lost it. I had asked my First Officer to instruct departure control that we were returning and he asked us if we needed assistance and gave me direct and 2000 ft. I instructed my First Officer to tell him to roll the emergency equipment.  As I slowed the aircraft down the trim became extremely heavy because the trim had failed at 275 kts and I was now below 160 kts to lower the landing gear. Before turning final I called for the gear to be extended.  At that point we only got one red unsafe light and one main gear light.  I turned final in hopes that the gear would come down but they did not.  I had to do a missed approach and go around.  On the go I told my First Officer to do an emergency gear extension.  I had all I could to maintain aircraft control at this point and it was quit difficult for my First Officer to reach across me to lower the gear.  We finally got three green lights and I turned to final.  We had no flaps; speed brakes; or thrust reversers to stop the aircraft.  I told my First Officer to prepare to stop the aircraft with the emergency brake system when we touched down.  I cut off the power over the overrun and the aircraft slammed onto the runway.  Both mains blew after the emergency brakes were applied and we started drifting for the left edge of the runway.  With much difficulty I managed to stop the aircraft close to the center of the runway about 700 ft from the end.  After stopping; I instructed my First Officer to get the passengers off the aircraft as I ran the shutdown checklist.  I soon followed and discovered that the left main gear was on fire so I put the fire out with the fire extinguisher.  NO ONE WAS HURT.  My First Officer did a wonderful job and without him the outcome could have been a lot different.  All this happened from startup to engine shutdown in just 3 tenths of an hour; we did not have a lot of time.

Callback: The reporter stated that a definitive cause of the electrical anomalies was not found but several electrical components along with both starter generators were replaced. The aircraft has since flown with no anomalies noted.



Synopsis: BE400 Captain reported a complete electrical failure shortly after takeoff; rendering PFD's; trim; landing gear and flaps inoperative. Emergency gear extension was used to lower the landing gear and emergency brakes used to stop the aircraft.
