Narrative:

We were filed IFR, flying practice INS approachs at waco regional (madison cooper) airport. After our second approach we were climbing out per ATC instructions and after tower handed us off to waco approach control we lost all electrical power. We briefly worked the problem, checked breakers and switches, then concluded power was lost. As it was VMC we proceeded to enter the traffic pattern in trail behind another twin we saw on crosswind. We observed a flashing green on downwind, continued base to final and received the steady green on final and landed. The FBO advised tower wanted me to call via phone whereupon the tower chief criticized my handling of the situation. He insinuated I didn't know lost communication procedure of circling clear of traffic pattern while squawking 7700/7600--pointless as our transponder was inoperative (he admitted our squawk disappeared off the tower radar). He also claimed I ignored his radio calls to enter a right-hand downwind for runway 19. Again, I had neither communication nor navigation receiver capabilities. Lastly, he assumed I would land regardless of the light gun signal given. I specifically told him if on final to 19 I had not seen a steady green light I would have made a low pass down the runway and gone around again in the pattern. It concerns me that I did what was necessary to land and the tower chief was more interested in what violation of procedures I committed and quibbling over details.

Narrative: WE WERE FILED IFR, FLYING PRACTICE INS APCHS AT WACO REGIONAL (MADISON COOPER) ARPT. AFTER OUR SECOND APCH WE WERE CLBING OUT PER ATC INSTRUCTIONS AND AFTER TWR HANDED US OFF TO WACO APCH CTL WE LOST ALL ELECTRICAL PWR. WE BRIEFLY WORKED THE PROB, CHKED BREAKERS AND SWITCHES, THEN CONCLUDED PWR WAS LOST. AS IT WAS VMC WE PROCEEDED TO ENTER THE TFC PATTERN IN TRAIL BEHIND ANOTHER TWIN WE SAW ON XWIND. WE OBSERVED A FLASHING GREEN ON DOWNWIND, CONTINUED BASE TO FINAL AND RECEIVED THE STEADY GREEN ON FINAL AND LANDED. THE FBO ADVISED TWR WANTED ME TO CALL VIA PHONE WHEREUPON THE TWR CHIEF CRITICIZED MY HANDLING OF THE SITUATION. HE INSINUATED I DIDN'T KNOW LOST COM PROC OF CIRCLING CLR OF TFC PATTERN WHILE SQUAWKING 7700/7600--POINTLESS AS OUR XPONDER WAS INOP (HE ADMITTED OUR SQUAWK DISAPPEARED OFF THE TWR RADAR). HE ALSO CLAIMED I IGNORED HIS RADIO CALLS TO ENTER A RIGHT-HAND DOWNWIND FOR RWY 19. AGAIN, I HAD NEITHER COM NOR NAV RECEIVER CAPABILITIES. LASTLY, HE ASSUMED I WOULD LAND REGARDLESS OF THE LIGHT GUN SIGNAL GIVEN. I SPECIFICALLY TOLD HIM IF ON FINAL TO 19 I HAD NOT SEEN A STEADY GREEN LIGHT I WOULD HAVE MADE A LOW PASS DOWN THE RWY AND GONE AROUND AGAIN IN THE PATTERN. IT CONCERNS ME THAT I DID WHAT WAS NECESSARY TO LAND AND THE TWR CHIEF WAS MORE INTERESTED IN WHAT VIOLATION OF PROCS I COMMITTED AND QUIBBLING OVER DETAILS.
