ELECTRICAL FAILURE ENCOUNTERED ON PA 28. PLT DECLARED EMER AFTER POWER BRIEFLY RESTORED AND WAS CLEARED FOR LOW APCH TO VERIFY GEAR DOWN; AND PLT RETURNED FOR SUCCESSFUL LNDG.

Narrative

IMMEDIATELY AFTER DEPARTING FROM ZZZ RWY 35; THE ACFT HAD A COMPLETE ELECTRICAL FAILURE. COMS AND THE ACFT'S XPONDER SIGNAL WERE LOST. I IMMEDIATELY SQUAWKED 7700 AND LEVELED OFF AT THE LAST ASSIGNED ALT 3500 FT MSL. AFTER LEAVING ZZZ1 AIRSPACE I FLEW TO ZZZ2 ARPT AND CIRCLED NEARBY WHILE TROUBLESHOOTING THE SIT. ELECTRICAL PWR WAS RESTORED AFTER THE EMER GEAR DOWN CHKLIST. AS THE GEAR CAME DOWN AND LOCKED THE ELECTRICAL PWR CAME BACK ON. I IMMEDIATELY CONTACTED ZZZ3 APCH AND INFORMED THEM OF MY SIT AND DECLARED AN URGENT SIT. I WAS TOLD THAT IF I LOST COM AGAIN THAT I WAS CLRED TO LAND RWY 17 AND WAS IMMEDIATELY CLRED FOR A LOW APCH ON RWY 17 IN ORDER TO VERIFY THE POS OF THE GEAR. TWR VERIFIED THAT GEAR WAS DOWN AND CLRED ME TO PERFORM A TEARDROP ENTRY TO THE FINAL APCH FOR RWY 35. ONCE ESTABLISHED ON FINAL I WAS CLRED TO LAND RWY 35. I THEN LANDED WITHOUT INCIDENT AND TAXIED TO PARKING UNDER MY OWN PWR. AFTER LNDG I GAVE THE REQUIRED INFO TO THE CRASH TEAM AND CONTACTED BOTH ZZZ2 AND ZZZ1 TWRS AND INFORMED THEM AS TO WHAT HAD HAPPENED. I BELIEVE THAT THE MAINT THAT HAD JUST BEEN PERFORMED ON THE ACFT MAY HAVE CAUSED THE ELECTRICAL FAILURE AS THIS WAS THE FIRST FLT AFTER THE REPLACEMENT OF THE ACFT STARTER. THE FAILURE OCCURRED AFTER THE FUEL PUMP WAS TURNED OFF AS THE AFTER TKOF CHKLIST CALLED FOR. WHEN THE FUEL PUMP WAS SWITCHED BACK ON; THE PWR WOULD FLASH ON IN OFF FOR ABOUT 1/2 A SECOND REPEATEDLY. THE GEAR COMING DOWN SOMEHOW RESTORED ELECTRICAL PWR WHICH I BELIEVE MUST HAVE JARED A WIRE OR CONNECTION.
