Narrative:

10 mi west of ft pierce airport, I noticed the oil pressure was way below minimums. I immediately initiated a 180 degree turn back toward ft pierce. I dialed ft pierce tower frequency back into communication 1. When I pushed down the transmit button, everything electrical died. I turned off everything electrical I could (lights, GPS, transponder), and tried to call again, but everything failed again. I tried to squawk an emergency on the transponder, but it failed as well. By that time, I was nearing the tower, so I descended down to 1300 ft. (Tpa is 1000 ft.) I proceeded to fly around the tower while violently rocking my wings, watching for traffic, and watching the tower for a light gun signal. I did not see one, so I decided to enter a high left downwind for the active runway 9. I continued to rock my wings on the entire left downwind, while watching for traffic. I saw 2 aircraft on final approach, and turned my left base after the second aircraft passed my left wing. I had still seen no light gun signals from the tower. I continued rocking my wings as much as possible on my base and final legs, and still saw nothing from the tower. I landed the plane and pulled off onto the first taxiway, where I sat watching for signals to taxi. After 5 mins, the txwys were clear, and I decided to taxi back to the ramp. I parked the aircraft and went inside, where I had a debriefing with a couple of my flight instructors.

Title: SMA PLT HAD LOW OIL PRESSURE, AND HAD A COMPLETE ELECTRICAL FAILURE AT FPR CLASS D.

Narrative: 10 MI W OF FT PIERCE ARPT, I NOTICED THE OIL PRESSURE WAS WAY BELOW MINIMUMS. I IMMEDIATELY INITIATED A 180 DEG TURN BACK TOWARD FT PIERCE. I DIALED FT PIERCE TWR FREQ BACK INTO COM 1. WHEN I PUSHED DOWN THE TRANSMIT BUTTON, EVERYTHING ELECTRICAL DIED. I TURNED OFF EVERYTHING ELECTRICAL I COULD (LIGHTS, GPS, XPONDER), AND TRIED TO CALL AGAIN, BUT EVERYTHING FAILED AGAIN. I TRIED TO SQUAWK AN EMER ON THE XPONDER, BUT IT FAILED AS WELL. BY THAT TIME, I WAS NEARING THE TWR, SO I DSNDED DOWN TO 1300 FT. (TPA IS 1000 FT.) I PROCEEDED TO FLY AROUND THE TWR WHILE VIOLENTLY ROCKING MY WINGS, WATCHING FOR TFC, AND WATCHING THE TWR FOR A LIGHT GUN SIGNAL. I DID NOT SEE ONE, SO I DECIDED TO ENTER A HIGH L DOWNWIND FOR THE ACTIVE RWY 9. I CONTINUED TO ROCK MY WINGS ON THE ENTIRE L DOWNWIND, WHILE WATCHING FOR TFC. I SAW 2 ACFT ON FINAL APCH, AND TURNED MY L BASE AFTER THE SECOND ACFT PASSED MY L WING. I HAD STILL SEEN NO LIGHT GUN SIGNALS FROM THE TWR. I CONTINUED ROCKING MY WINGS AS MUCH AS POSSIBLE ON MY BASE AND FINAL LEGS, AND STILL SAW NOTHING FROM THE TWR. I LANDED THE PLANE AND PULLED OFF ONTO THE FIRST TXWY, WHERE I SAT WATCHING FOR SIGNALS TO TAXI. AFTER 5 MINS, THE TXWYS WERE CLR, AND I DECIDED TO TAXI BACK TO THE RAMP. I PARKED THE ACFT AND WENT INSIDE, WHERE I HAD A DEBRIEFING WITH A COUPLE OF MY FLT INSTRUCTORS.
