Narrative:

We departed brackett field (poc) at approximately XA30 local and proceeded to fly to avalon, catalina direct. Our initial altitude was 4500 ft due to airspace out of lax. I requested and received flight following from ontario approach. I was in contact with ATC until I reached the coast where service was terminated. I then proceeded to climb to 6500 ft. At approximately 10 mi out from avalon, I contacted avalon unicom and requested landing advisories. I was told avalon was using right hand traffic on runway 22. I then proceeded to place the plane in a path as to enter the traffic pattern on a 45 degree to downwind. Upon entering into the 45 degree I was at 2600 ft and was traveling at under 100 nautical mph indicated. I proceeded to lower the gear and add 1 notch of flaps. I then did a gumps check, confirming that the gear was down, the 3 green lights were illuminated. I was ready to turn downwind and reported it to unicom. I proceeded to perform 2 more gumps checks, 1 on base and 1 on final. There was no indication that the gear was not down and locked until I flared to land and the propeller began to strike the ground. The plane skidded for approximately 60 ft and came to rest on the hard surface. There were no injuries to the 3 passenger or myself. Upon examining the plane after the incident, I noticed that the nose gear doors were open and intact and also the 2 main gears were open approximately 3 inches. Callback conversation with reporter revealed the following information: the reporting pilot states that an investigator determined that there was an electrical problem with the landing gear and that something shorted out when the gear was raised after takeoff. The gear never came down because of the electrical problem, but the electrical problem showed the 3 green lights even though the gear was up. There were no injuries. The flaps, propeller, belly pan, and nose gear door were all damaged. There has been no FAA action to date.

Title: AN SMA LANDED GEAR UP AFTER EXPERIENCING AN ELECTRICAL PROB.

Narrative: WE DEPARTED BRACKETT FIELD (POC) AT APPROX XA30 LCL AND PROCEEDED TO FLY TO AVALON, CATALINA DIRECT. OUR INITIAL ALT WAS 4500 FT DUE TO AIRSPACE OUT OF LAX. I REQUESTED AND RECEIVED FLT FOLLOWING FROM ONTARIO APCH. I WAS IN CONTACT WITH ATC UNTIL I REACHED THE COAST WHERE SVC WAS TERMINATED. I THEN PROCEEDED TO CLB TO 6500 FT. AT APPROX 10 MI OUT FROM AVALON, I CONTACTED AVALON UNICOM AND REQUESTED LNDG ADVISORIES. I WAS TOLD AVALON WAS USING R HAND TFC ON RWY 22. I THEN PROCEEDED TO PLACE THE PLANE IN A PATH AS TO ENTER THE TFC PATTERN ON A 45 DEG TO DOWNWIND. UPON ENTERING INTO THE 45 DEG I WAS AT 2600 FT AND WAS TRAVELING AT UNDER 100 NAUTICAL MPH INDICATED. I PROCEEDED TO LOWER THE GEAR AND ADD 1 NOTCH OF FLAPS. I THEN DID A GUMPS CHK, CONFIRMING THAT THE GEAR WAS DOWN, THE 3 GREEN LIGHTS WERE ILLUMINATED. I WAS READY TO TURN DOWNWIND AND RPTED IT TO UNICOM. I PROCEEDED TO PERFORM 2 MORE GUMPS CHKS, 1 ON BASE AND 1 ON FINAL. THERE WAS NO INDICATION THAT THE GEAR WAS NOT DOWN AND LOCKED UNTIL I FLARED TO LAND AND THE PROP BEGAN TO STRIKE THE GND. THE PLANE SKIDDED FOR APPROX 60 FT AND CAME TO REST ON THE HARD SURFACE. THERE WERE NO INJURIES TO THE 3 PAX OR MYSELF. UPON EXAMINING THE PLANE AFTER THE INCIDENT, I NOTICED THAT THE NOSE GEAR DOORS WERE OPEN AND INTACT AND ALSO THE 2 MAIN GEARS WERE OPEN APPROX 3 INCHES. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTING PLT STATES THAT AN INVESTIGATOR DETERMINED THAT THERE WAS AN ELECTRICAL PROB WITH THE LNDG GEAR AND THAT SOMETHING SHORTED OUT WHEN THE GEAR WAS RAISED AFTER TKOF. THE GEAR NEVER CAME DOWN BECAUSE OF THE ELECTRICAL PROB, BUT THE ELECTRICAL PROB SHOWED THE 3 GREEN LIGHTS EVEN THOUGH THE GEAR WAS UP. THERE WERE NO INJURIES. THE FLAPS, PROP, BELLY PAN, AND NOSE GEAR DOOR WERE ALL DAMAGED. THERE HAS BEEN NO FAA ACTION TO DATE.
