Coming back from a training session in ZZZ1, during which the pilot performed 11 takeoffs and lndgs, the pilot contacted ZZZ tower when passing over a VFR check point at 6500 ft with current ATIS and requesting full stop landing. Tower replied, asking the pilot to come on a base leg for runway 31R and report 3 mi on base. At reporting point, pilot did the report and did not receive an acknowledgement from ATC. Checked communication #1 and realized communication #1 was not working. Pilot switched to communication #2 and could hear ATC calling him, but when pilot tried to contact ATC, they didn't reply. Pilot assumed communication failure. Arriving on final with too much altitude, decided to do a 360 degree and prepare landing as expected by ATC, still monitoring communication #2. During the 360 degree, pilot put flaps and put gear control in down position. During 360 degree, pilot lost totally communication #2 (couldn't hear ATC on communication #2). Pilot tried to reset master without success and checked battery load which was close to zero. At this point, the airplane was on proper path for landing. Pilot couldn't see any light signal from tower, or any airplane on the runway or about to enter the runway, so the pilot decided to flare and land the airplane. Airplane landed on the centerline without gear and came to a stop on the right side of runway 31R. Gear up warning horn never came on. The gear up landing is due to the inability of the pilot to follow the correct, normal, and emergency checklists after discovering the electrical system failure. Factors that have affected the situation are: situation occurred during the landing phase. The progressive failure of components related to the electric system led the pilot to realize, too late, that the loss of communication was related to a much more serious problem that would affect other system of the airplane. Pilot was coming back from a long training flight and was tired. The pilot should have performed a go around and stayed away from the airport until he had finished assessing the situation and making sure that he could perform a landing as safe as possible. Then got back to the airport and wait for light signals from the tower.

Title: A LOW TIME PA28 PLT REALIZED, TOO LATE, THAT HIS ELECTRICAL SYS FAILURE CAUSED HIS COM FAILURE AND THAT THE GEAR HE HAD LOWERED WAS ACTUALLY STILL RETRACTED. THIS WAS NOT DISCOVERED UNTIL AFTER HIS GEAR UP LNDG AT ZZZ.
Narrative: COMING BACK FROM A TRAINING SESSION IN ZZZ1, DURING WHICH THE PLT PERFORMED 11 TKOFS AND LNDGS, THE PLT CONTACTED ZZZ TWR WHEN PASSING OVER A VFR CHK POINT AT 6500 FT WITH CURRENT ATIS AND REQUESTING FULL STOP LNDG. TWR REPLIED, ASKING THE PLT TO COME ON A BASE LEG FOR RWY 31R AND RPT 3 MI ON BASE. AT RPTING POINT, PLT DID THE RPT AND DID NOT RECEIVE AN ACKNOWLEDGEMENT FROM ATC. CHKED COM #1 AND REALIZED COM #1 WAS NOT WORKING. PLT SWITCHED TO COM #2 AND COULD HEAR ATC CALLING HIM, BUT WHEN PLT TRIED TO CONTACT ATC, THEY DIDN'T REPLY. PLT ASSUMED COM FAILURE. ARRIVING ON FINAL WITH TOO MUCH ALT, DECIDED TO DO A 360 DEG AND PREPARE LNDG AS EXPECTED BY ATC, STILL MONITORING COM #2. DURING THE 360 DEG, PLT PUT FLAPS AND PUT GEAR CTL IN DOWN POS. DURING 360 DEG, PLT LOST TOTALLY COM #2 (COULDN'T HEAR ATC ON COM #2). PLT TRIED TO RESET MASTER WITHOUT SUCCESS AND CHKED BATTERY LOAD WHICH WAS CLOSE TO ZERO. AT THIS POINT, THE AIRPLANE WAS ON PROPER PATH FOR LNDG. PLT COULDN'T SEE ANY LIGHT SIGNAL FROM TWR, OR ANY AIRPLANE ON THE RWY OR ABOUT TO ENTER THE RWY, SO THE PLT DECIDED TO FLARE AND LAND THE AIRPLANE. AIRPLANE LANDED ON THE CTRLINE WITHOUT GEAR AND CAME TO A STOP ON THE R SIDE OF RWY 31R. GEAR UP WARNING HORN NEVER CAME ON. THE GEAR UP LNDG IS DUE TO THE INABILITY OF THE PLT TO FOLLOW THE CORRECT, NORMAL, AND EMER CHKLISTS AFTER DISCOVERING THE ELECTRICAL SYS FAILURE. FACTORS THAT HAVE AFFECTED THE SIT ARE: SIT OCCURRED DURING THE LNDG PHASE. THE PROGRESSIVE FAILURE OF COMPONENTS RELATED TO THE ELECTRIC SYS LED THE PLT TO REALIZE, TOO LATE, THAT THE LOSS OF COM WAS RELATED TO A MUCH MORE SERIOUS PROB THAT WOULD AFFECT OTHER SYS OF THE AIRPLANE. PLT WAS COMING BACK FROM A LONG TRAINING FLT AND WAS TIRED. THE PLT SHOULD HAVE PERFORMED A GAR AND STAYED AWAY FROM THE ARPT UNTIL HE HAD FINISHED ASSESSING THE SIT AND MAKING SURE THAT HE COULD PERFORM A LNDG AS SAFE AS POSSIBLE. THEN GOT BACK TO THE ARPT AND WAIT FOR LIGHT SIGNALS FROM THE TWR.
