Narrative:
I was flying VFR from ZZZ to ZZZ1. I would normally file IFR for this flight; but the WX had been very clear and stable. I did request and received TA's from ZZZ approach and subsequently ZZZ2 approach and ZZZ2 center. The flight was not eventful until I was approximately 45 mi from ZZZ1. It was then that center told me they had lost my transponder signal. I recycled the transponder and received another barely audible transmission from center. When repeated; I understood the controller was terminating radar services because he was not receiving my transponder. I continued trying to get the transponder to work when I noticed the radios had gone silent. I flipped through several frequencys without luck. I put 7600 in the transponder in case anybody picked it up. I noticed the alternator gauge was reading zero but more importantly that it did not budge when I turned off the alternator switch. I realized then I was experiencing a full electrical failure. I then switched the code from 7600 to 7700 but knew it was only a formality. Using my battery pwred GPS; I turned toward the nearest airport (ZZZ3); and went through alternator failure checklist. I tried to put down my landing gear and of course the pump did not work and I had no landing gear lights. Because I did not see any activity on ZZZ3 and; therefore; no one to come to my aid if needed; I turned toward ZZZ4; a slightly larger city and an airport with more activity. I quickly realized; however; that what I needed was a twred airport that could utilize a light gun to signal to me if it appeared my landing gear was down. The nearest twred airport was ZZZ1. I turned again to ZZZ1. I went through the emergency gear down checklist to familiarize myself with what I would have to do upon arrival in ZZZ1. I then reviewed the light signals from my knee board to know what to expect from the tower. I entered the ZZZ1 class C airspace at a low altitude and with a very focused scan trying to avoid other traffic. I entered the pattern at ZZZ1 after carefully scanning for traffic. I then proceeded to perform the emergency gear down procedure. I descended to approximately 400 ft and overflew the runway yawing the airplane abruptly as recommended in the emergency procedure expecting that would alert the tower I could not talk to them and that I was hoping my gear was down and locked. Because the tower at ZZZ1 is near the end of the active runway; I figured it would take the tower the time I took for another pass to get the light gun ready and signal me. I went around the pattern and again over the runway yawed the airplane and stared at the tower. There was no light. I thought perhaps they did not see me...I'll go by one more time. When completing my third pass; I saw the fire trucks pull onto the field and begin positioning themselves along various points adjacent to the runway. I decided it was time to try to land. I slowed to the slowest safe speed and right before touchdown I pulled the mixture to cutoff. Almost simultaneously; I touched down and realized the wheels were down. I quickly pushed the mixture to rich and kept the engine running and was able to taxi off the runway. I followed one of the fire engines to the ramp. The driver of the fire truck asked me what happened and I told him I had an electrical failure. He said that's what the tower figured. He then said the tower tried to signal me but the light gun didn't work; and that they had changed batteries but the gun still did not work. The next day the alternator was replaced and I flew to ZZZ without incident. I learned that I should expect gauges to work and not ignore them just because they have been inaccurate in the past. I learned a battery pwred GPS and a handheld radio are essential in airplanes. I have tried to analyze what option I had to entering class C airspace without 2-WAY communication at ZZZ1; but due to the emergency; I don't think I had a better alternative. I learned from the control tower supervisor that after you overfly the runway they prefer you circle 'off' the field while you wait for a light signal. Frankly; I had never heard this before. Lastly; I learned I should say goodbye to my wife and children before we head out the door each morning. You never know what life has in store.

Title: PA28 PVT PLT EXPERIENCED AN ELECTRICAL FAILURE AND LANDED WITHOUT INCIDENT.
Narrative: I WAS FLYING VFR FROM ZZZ TO ZZZ1. I WOULD NORMALLY FILE IFR FOR THIS FLT; BUT THE WX HAD BEEN VERY CLR AND STABLE. I DID REQUEST AND RECEIVED TA'S FROM ZZZ APCH AND SUBSEQUENTLY ZZZ2 APCH AND ZZZ2 CTR. THE FLT WAS NOT EVENTFUL UNTIL I WAS APPROX 45 MI FROM ZZZ1. IT WAS THEN THAT CTR TOLD ME THEY HAD LOST MY XPONDER SIGNAL. I RECYCLED THE XPONDER AND RECEIVED ANOTHER BARELY AUDIBLE XMISSION FROM CTR. WHEN REPEATED; I UNDERSTOOD THE CTLR WAS TERMINATING RADAR SVCS BECAUSE HE WAS NOT RECEIVING MY XPONDER. I CONTINUED TRYING TO GET THE XPONDER TO WORK WHEN I NOTICED THE RADIOS HAD GONE SILENT. I FLIPPED THROUGH SEVERAL FREQS WITHOUT LUCK. I PUT 7600 IN THE XPONDER IN CASE ANYBODY PICKED IT UP. I NOTICED THE ALTERNATOR GAUGE WAS READING ZERO BUT MORE IMPORTANTLY THAT IT DID NOT BUDGE WHEN I TURNED OFF THE ALTERNATOR SWITCH. I REALIZED THEN I WAS EXPERIENCING A FULL ELECTRICAL FAILURE. I THEN SWITCHED THE CODE FROM 7600 TO 7700 BUT KNEW IT WAS ONLY A FORMALITY. USING MY BATTERY PWRED GPS; I TURNED TOWARD THE NEAREST ARPT (ZZZ3); AND WENT THROUGH ALTERNATOR FAILURE CHKLIST. I TRIED TO PUT DOWN MY LNDG GEAR AND OF COURSE THE PUMP DID NOT WORK AND I HAD NO LNDG GEAR LIGHTS. BECAUSE I DID NOT SEE ANY ACTIVITY ON ZZZ3 AND; THEREFORE; NO ONE TO COME TO MY AID IF NEEDED; I TURNED TOWARD ZZZ4; A SLIGHTLY LARGER CITY AND AN ARPT WITH MORE ACTIVITY. I QUICKLY REALIZED; HOWEVER; THAT WHAT I NEEDED WAS A TWRED ARPT THAT COULD UTILIZE A LIGHT GUN TO SIGNAL TO ME IF IT APPEARED MY LNDG GEAR WAS DOWN. THE NEAREST TWRED ARPT WAS ZZZ1. I TURNED AGAIN TO ZZZ1. I WENT THROUGH THE EMER GEAR DOWN CHKLIST TO FAMILIARIZE MYSELF WITH WHAT I WOULD HAVE TO DO UPON ARR IN ZZZ1. I THEN REVIEWED THE LIGHT SIGNALS FROM MY KNEE BOARD TO KNOW WHAT TO EXPECT FROM THE TWR. I ENTERED THE ZZZ1 CLASS C AIRSPACE AT A LOW ALT AND WITH A VERY FOCUSED SCAN TRYING TO AVOID OTHER TFC. I ENTERED THE PATTERN AT ZZZ1 AFTER CAREFULLY SCANNING FOR TFC. I THEN PROCEEDED TO PERFORM THE EMER GEAR DOWN PROC. I DSNDED TO APPROX 400 FT AND OVERFLEW THE RWY YAWING THE AIRPLANE ABRUPTLY AS RECOMMENDED IN THE EMER PROC EXPECTING THAT WOULD ALERT THE TWR I COULD NOT TALK TO THEM AND THAT I WAS HOPING MY GEAR WAS DOWN AND LOCKED. BECAUSE THE TWR AT ZZZ1 IS NEAR THE END OF THE ACTIVE RWY; I FIGURED IT WOULD TAKE THE TWR THE TIME I TOOK FOR ANOTHER PASS TO GET THE LIGHT GUN READY AND SIGNAL ME. I WENT AROUND THE PATTERN AND AGAIN OVER THE RWY YAWED THE AIRPLANE AND STARED AT THE TWR. THERE WAS NO LIGHT. I THOUGHT PERHAPS THEY DID NOT SEE ME...I'LL GO BY ONE MORE TIME. WHEN COMPLETING MY THIRD PASS; I SAW THE FIRE TRUCKS PULL ONTO THE FIELD AND BEGIN POSITIONING THEMSELVES ALONG VARIOUS POINTS ADJACENT TO THE RWY. I DECIDED IT WAS TIME TO TRY TO LAND. I SLOWED TO THE SLOWEST SAFE SPD AND RIGHT BEFORE TOUCHDOWN I PULLED THE MIXTURE TO CUTOFF. ALMOST SIMULTANEOUSLY; I TOUCHED DOWN AND REALIZED THE WHEELS WERE DOWN. I QUICKLY PUSHED THE MIXTURE TO RICH AND KEPT THE ENG RUNNING AND WAS ABLE TO TAXI OFF THE RWY. I FOLLOWED ONE OF THE FIRE ENGS TO THE RAMP. THE DRIVER OF THE FIRE TRUCK ASKED ME WHAT HAPPENED AND I TOLD HIM I HAD AN ELECTRICAL FAILURE. HE SAID THAT'S WHAT THE TWR FIGURED. HE THEN SAID THE TWR TRIED TO SIGNAL ME BUT THE LIGHT GUN DIDN'T WORK; AND THAT THEY HAD CHANGED BATTERIES BUT THE GUN STILL DID NOT WORK. THE NEXT DAY THE ALTERNATOR WAS REPLACED AND I FLEW TO ZZZ WITHOUT INCIDENT. I LEARNED THAT I SHOULD EXPECT GAUGES TO WORK AND NOT IGNORE THEM JUST BECAUSE THEY HAVE BEEN INACCURATE IN THE PAST. I LEARNED A BATTERY PWRED GPS AND A HANDHELD RADIO ARE ESSENTIAL IN AIRPLANES. I HAVE TRIED TO ANALYZE WHAT OPTION I HAD TO ENTERING CLASS C AIRSPACE WITHOUT 2-WAY COM AT ZZZ1; BUT DUE TO THE EMER; I DON'T THINK I HAD A BETTER ALTERNATIVE. I LEARNED FROM THE CTL TWR SUPVR THAT AFTER YOU OVERFLY THE RWY THEY PREFER YOU CIRCLE 'OFF' THE FIELD WHILE YOU WAIT FOR A LIGHT SIGNAL. FRANKLY; I HAD NEVER HEARD THIS BEFORE. LASTLY; I LEARNED I SHOULD SAY GOODBYE TO MY WIFE AND CHILDREN BEFORE WE HEAD OUT THE DOOR EACH MORNING. YOU NEVER KNOW WHAT LIFE HAS IN STORE.
