Narrative:

Acting as first officer I attempted to raise the electrically operated gear after takeoff. The gear did not come up and all generators were lost causing total electrical failure and loss of contact with tower. The last instructions from tower were to maintain runway heading. Rather than fly at 500' over downtown miami in the takeoff confign the captain decided to turn right and enter a right downwind to 09R (our takeoff runway). Shortly after the right turn was initiated and about 30 second to 1 min after breaking ground the engineer got a generator back and radio contact was reestablished with tower who gave us permission to enter downwind and land which was done safely. I feel the capts right turn west/O tower approval was the correct action. Gear and flaps were both in the takeoff position and in the event of an engine loss at maximum takeoff gross weight altitude would have been hard to maintain and we would have been over downtown miami.

Title: FLC OF 4 ENGINE PISTON ATX FRT ACFT EXPERIENCES TOTAL ELECTRICAL FAILURE AT TKOF.

Narrative: ACTING AS F/O I ATTEMPTED TO RAISE THE ELECTRICALLY OPERATED GEAR AFTER TKOF. THE GEAR DID NOT COME UP AND ALL GENERATORS WERE LOST CAUSING TOTAL ELECTRICAL FAILURE AND LOSS OF CONTACT WITH TWR. THE LAST INSTRUCTIONS FROM TWR WERE TO MAINTAIN RWY HDG. RATHER THAN FLY AT 500' OVER DOWNTOWN MIAMI IN THE TKOF CONFIGN THE CAPT DECIDED TO TURN R AND ENTER A R DOWNWIND TO 09R (OUR TKOF RWY). SHORTLY AFTER THE R TURN WAS INITIATED AND ABOUT 30 SEC TO 1 MIN AFTER BREAKING GND THE ENGINEER GOT A GENERATOR BACK AND RADIO CONTACT WAS REESTABLISHED WITH TWR WHO GAVE US PERMISSION TO ENTER DOWNWIND AND LAND WHICH WAS DONE SAFELY. I FEEL THE CAPTS R TURN W/O TWR APPROVAL WAS THE CORRECT ACTION. GEAR AND FLAPS WERE BOTH IN THE TKOF POS AND IN THE EVENT OF AN ENG LOSS AT MAX TKOF GROSS WEIGHT ALT WOULD HAVE BEEN HARD TO MAINTAIN AND WE WOULD HAVE BEEN OVER DOWNTOWN MIAMI.
