Narrative:

Was giving instrument training to friend. While holding over lit VOR we had a total electrical failure. Training was VFR and pilot was not wearing a hood. Pilot had no idea what to do or how to land (2000 plus hours). I suggested he fly toward the tower which is approximately 3 NM from VOR. Not to cross any runways and to wag his wings to get ATC attention and look for green light. We received a flashing green light so we flew downwind to runway. We received another flashing green light. Due to myself not flying hardly any or instructing within the last 90 days, I could not remember if we needed a flashing green light or steady green. We both thought we received a steady green before turning base leg, but was hard to tell due to haze and late afternoon. We both still could not remember which light we needed. Checking for traffic and not seeing any, we landed. After entering taxiway we looked for additional light signals, but did not see any, so we taxied to FBO. After returning to FBO, I looked in the aim to check on light signals. My lesson: although I was not PIC I still should have reviewed rules, regulations, etc before flying again since it had been a long time and the student is always going to assume the instructor will know what to do (and he should).

Title: DURING A NIGHT INST TRAINING FLT IN A SMA SEL, WHILE HOLDING NEAR THE ARPT, TOTAL ELECTRICAL FAILURE WAS EXPERIENCED. TWR LIGHT SIGNALS WERE USED TO RETURN AND LAND.

Narrative: WAS GIVING INST TRAINING TO FRIEND. WHILE HOLDING OVER LIT VOR WE HAD A TOTAL ELECTRICAL FAILURE. TRAINING WAS VFR AND PLT WAS NOT WEARING A HOOD. PLT HAD NO IDEA WHAT TO DO OR HOW TO LAND (2000 PLUS HRS). I SUGGESTED HE FLY TOWARD THE TWR WHICH IS APPROX 3 NM FROM VOR. NOT TO CROSS ANY RWYS AND TO WAG HIS WINGS TO GET ATC ATTN AND LOOK FOR GREEN LIGHT. WE RECEIVED A FLASHING GREEN LIGHT SO WE FLEW DOWNWIND TO RWY. WE RECEIVED ANOTHER FLASHING GREEN LIGHT. DUE TO MYSELF NOT FLYING HARDLY ANY OR INSTRUCTING WITHIN THE LAST 90 DAYS, I COULD NOT REMEMBER IF WE NEEDED A FLASHING GREEN LIGHT OR STEADY GREEN. WE BOTH THOUGHT WE RECEIVED A STEADY GREEN BEFORE TURNING BASE LEG, BUT WAS HARD TO TELL DUE TO HAZE AND LATE AFTERNOON. WE BOTH STILL COULD NOT REMEMBER WHICH LIGHT WE NEEDED. CHKING FOR TFC AND NOT SEEING ANY, WE LANDED. AFTER ENTERING TXWY WE LOOKED FOR ADDITIONAL LIGHT SIGNALS, BUT DID NOT SEE ANY, SO WE TAXIED TO FBO. AFTER RETURNING TO FBO, I LOOKED IN THE AIM TO CHK ON LIGHT SIGNALS. MY LESSON: ALTHOUGH I WAS NOT PIC I STILL SHOULD HAVE REVIEWED RULES, REGS, ETC BEFORE FLYING AGAIN SINCE IT HAD BEEN A LONG TIME AND THE STUDENT IS ALWAYS GOING TO ASSUME THE INSTRUCTOR WILL KNOW WHAT TO DO (AND HE SHOULD).
