Narrative:

On the above date my student, training for a chkout in the airplane, and I departed N07 to practice lndgs at cdw airport. On the first landing on downwind the gear was extended. No right main down light was indicated. The gear was recycled with no change in indication. I then switched the right main light bulb with the left bulb. The bulb worked in the left gear light position. I then informed cdw tower that we did not have a right main down and locked indication. I asked for a departure to the north to troubleshoot and I would call them when I had more information. We turned base and leveled at 1200 ft MSL and flew slightly right of runway 4 as we departed to the north. Upon clearing cdw class D airspace we read the checklist for gear extension manually. After following the procedures, no right main indication was received. I then contacted cdw tower and asked for a low fly-by and to have someone check to see if they saw the right main down. After the fly-by, tower informed us that the gear appeared down. I asked the tower to have the fire trucks standing by. Tower asked if I was declaring an emergency. I said yes I was. Tower informed me it would take 5-7 mins to have the trucks there. They asked me to circle the field at 1700 ft MSL. We circled until tower informed us that the trucks were positioned. We then set up for a downwind and approach and final where tower again informed us that the gear appeared down. We landed without incident. After landing we taxied to cdw FBO and shut down. In hindsight, we should have shut down on the runway and been towed to the FBO. During the entire ordeal the 2 of us communicated our intentions (2 pilots on board) and opinions. Excellent crew and ATC communications I feel led to a safe, uneventful landing. Upon inspection by company mechanics, the problem was determined to be a broken wire. This was fixed the next day and signed off in the logbook (maintenance) and the airplane flown back to home base. The only possible different procedure I believe should have been followed was immediate shutdown after landing.

Title: PA44 R MAIN GEAR LIGHT FAILED TO ILLUMINATE WHILE ON APCH. ALL PROCS FOLLOWED AND MADE A NORMAL LNDG.

Narrative: ON THE ABOVE DATE MY STUDENT, TRAINING FOR A CHKOUT IN THE AIRPLANE, AND I DEPARTED N07 TO PRACTICE LNDGS AT CDW ARPT. ON THE FIRST LNDG ON DOWNWIND THE GEAR WAS EXTENDED. NO R MAIN DOWN LIGHT WAS INDICATED. THE GEAR WAS RECYCLED WITH NO CHANGE IN INDICATION. I THEN SWITCHED THE R MAIN LIGHT BULB WITH THE L BULB. THE BULB WORKED IN THE L GEAR LIGHT POS. I THEN INFORMED CDW TWR THAT WE DID NOT HAVE A R MAIN DOWN AND LOCKED INDICATION. I ASKED FOR A DEP TO THE N TO TROUBLESHOOT AND I WOULD CALL THEM WHEN I HAD MORE INFO. WE TURNED BASE AND LEVELED AT 1200 FT MSL AND FLEW SLIGHTLY R OF RWY 4 AS WE DEPARTED TO THE N. UPON CLRING CDW CLASS D AIRSPACE WE READ THE CHKLIST FOR GEAR EXTENSION MANUALLY. AFTER FOLLOWING THE PROCS, NO R MAIN INDICATION WAS RECEIVED. I THEN CONTACTED CDW TWR AND ASKED FOR A LOW FLY-BY AND TO HAVE SOMEONE CHK TO SEE IF THEY SAW THE R MAIN DOWN. AFTER THE FLY-BY, TWR INFORMED US THAT THE GEAR APPEARED DOWN. I ASKED THE TWR TO HAVE THE FIRE TRUCKS STANDING BY. TWR ASKED IF I WAS DECLARING AN EMER. I SAID YES I WAS. TWR INFORMED ME IT WOULD TAKE 5-7 MINS TO HAVE THE TRUCKS THERE. THEY ASKED ME TO CIRCLE THE FIELD AT 1700 FT MSL. WE CIRCLED UNTIL TWR INFORMED US THAT THE TRUCKS WERE POSITIONED. WE THEN SET UP FOR A DOWNWIND AND APCH AND FINAL WHERE TWR AGAIN INFORMED US THAT THE GEAR APPEARED DOWN. WE LANDED WITHOUT INCIDENT. AFTER LNDG WE TAXIED TO CDW FBO AND SHUT DOWN. IN HINDSIGHT, WE SHOULD HAVE SHUT DOWN ON THE RWY AND BEEN TOWED TO THE FBO. DURING THE ENTIRE ORDEAL THE 2 OF US COMMUNICATED OUR INTENTIONS (2 PLTS ON BOARD) AND OPINIONS. EXCELLENT CREW AND ATC COMS I FEEL LED TO A SAFE, UNEVENTFUL LNDG. UPON INSPECTION BY COMPANY MECHS, THE PROB WAS DETERMINED TO BE A BROKEN WIRE. THIS WAS FIXED THE NEXT DAY AND SIGNED OFF IN THE LOGBOOK (MAINT) AND THE AIRPLANE FLOWN BACK TO HOME BASE. THE ONLY POSSIBLE DIFFERENT PROC I BELIEVE SHOULD HAVE BEEN FOLLOWED WAS IMMEDIATE SHUTDOWN AFTER LNDG.
