Narrative:

I went to the aircraft and preflted it. I checked fuel tanks visually. I then proceeded to turn on the master and found the battery was dead. I then had a lineman set up a battery to start the aircraft with the external power plug. The aircraft checked out the fuel gauges and voltage. After checking all gauges, observer also a pilot got into the aircraft and we taxied to runway 1, did a runup and all checked well. I took off and put the go around up. The gear was retracting, we had 3 green and a gear unsafe light. At that time all electric power in the aircraft failed. I decided not to go to hpn our destination, only 25 mi away, because we had no radios. We could not put the gear down, so I did the emergency gear extension, which I had to do 3 weeks earlier on different aircraft, the same model as this aircraft. Passenger also read the procedure in the manual to be sure it was correct. We wiggled the aircraft left and right and up and down, not knowing if the gear was up or not. Because of the electrical failure, the lights did not work and the radios were inoperative. I made the decision to land back at lincoln park, nj under the assumption that the landing gear was not down. As I flared, the aircraft settled onto its tail, then its belly and propeller. The flaps were in the takeoff position because they were electric and inoperative after the electric failure. Minor damage was done to the aircraft at the bottom of the fuselage and to the propeller. Upon presentation of my documents to the FAA inspector, I discovered that my medical certificate had expired. I immediately scheduled a medical examination and received my current medical certificate.

Title: PLT OF SMA MADE GEAR UP LNDG AFTER ELECTRICAL FAILURE AND UNABLE TO RAISE OR LOWER GEAR.

Narrative: I WENT TO THE ACFT AND PREFLTED IT. I CHKED FUEL TANKS VISUALLY. I THEN PROCEEDED TO TURN ON THE MASTER AND FOUND THE BATTERY WAS DEAD. I THEN HAD A LINEMAN SET UP A BATTERY TO START THE ACFT WITH THE EXTERNAL PWR PLUG. THE ACFT CHKED OUT THE FUEL GAUGES AND VOLTAGE. AFTER CHKING ALL GAUGES, OBSERVER ALSO A PLT GOT INTO THE ACFT AND WE TAXIED TO RWY 1, DID A RUNUP AND ALL CHKED WELL. I TOOK OFF AND PUT THE GAR UP. THE GEAR WAS RETRACTING, WE HAD 3 GREEN AND A GEAR UNSAFE LIGHT. AT THAT TIME ALL ELECTRIC PWR IN THE ACFT FAILED. I DECIDED NOT TO GO TO HPN OUR DEST, ONLY 25 MI AWAY, BECAUSE WE HAD NO RADIOS. WE COULD NOT PUT THE GEAR DOWN, SO I DID THE EMER GEAR EXTENSION, WHICH I HAD TO DO 3 WKS EARLIER ON DIFFERENT ACFT, THE SAME MODEL AS THIS ACFT. PAX ALSO READ THE PROC IN THE MANUAL TO BE SURE IT WAS CORRECT. WE WIGGLED THE ACFT LEFT AND RIGHT AND UP AND DOWN, NOT KNOWING IF THE GEAR WAS UP OR NOT. BECAUSE OF THE ELECTRICAL FAILURE, THE LIGHTS DID NOT WORK AND THE RADIOS WERE INOP. I MADE THE DECISION TO LAND BACK AT LINCOLN PARK, NJ UNDER THE ASSUMPTION THAT THE LNDG GEAR WAS NOT DOWN. AS I FLARED, THE ACFT SETTLED ONTO ITS TAIL, THEN ITS BELLY AND PROP. THE FLAPS WERE IN THE TKOF POS BECAUSE THEY WERE ELECTRIC AND INOP AFTER THE ELECTRIC FAILURE. MINOR DAMAGE WAS DONE TO THE ACFT AT THE BOTTOM OF THE FUSELAGE AND TO THE PROP. UPON PRESENTATION OF MY DOCUMENTS TO THE FAA INSPECTOR, I DISCOVERED THAT MY MEDICAL CERTIFICATE HAD EXPIRED.
