Narrative:

After completing a series of takeoffs and lndgs, a final landing was anticipated. The gear was selected down. The right main gear light did not illuminate. Moving the bulbs around showed the lights were not burned out. The gear had been cycled 7-15 times during the flight with nothing but normal results. The gear was then recycled -- same result. The checklist for emergency gear extension was run from memory -- still no right main gear indication of down and locked. A tower fly-by indicated what appeared to be a normal gear indication for landing. We then headed north on an extended downwind. I flew the airplane, the other pilot pulled out the emergency gear extension checklist. Careful review of the checklist showed that all items had been completed. Runway 22 was selected to give a left crosswind. The controller declared an emergency for us. On final, the right main gear light illuminated for a fraction of a second. Landing confirmed that the right main gear was down and locked. In retrospect certain inaction on my part should have been avoided. At the time of the event, I should have stated, biennial flight review is over, we want to just get the aircraft and occupants on ground safely. I should have declared emergency, not tower. Otherwise, as a crew, the other pilot and myself worked well together to resolve the problem by dividing the work to be done and doing it. Felt good CRM skills displayed at this time.

Title: ACFT EQUIP PROB. LNDG GEAR INDICATOR. TWR FLY-BY SHOWED GEAR DOWN, TWR DECLARED EMER AND LNDG WAS UNEVENTFUL.

Narrative: AFTER COMPLETING A SERIES OF TKOFS AND LNDGS, A FINAL LNDG WAS ANTICIPATED. THE GEAR WAS SELECTED DOWN. THE R MAIN GEAR LIGHT DID NOT ILLUMINATE. MOVING THE BULBS AROUND SHOWED THE LIGHTS WERE NOT BURNED OUT. THE GEAR HAD BEEN CYCLED 7-15 TIMES DURING THE FLT WITH NOTHING BUT NORMAL RESULTS. THE GEAR WAS THEN RECYCLED -- SAME RESULT. THE CHKLIST FOR EMER GEAR EXTENSION WAS RUN FROM MEMORY -- STILL NO R MAIN GEAR INDICATION OF DOWN AND LOCKED. A TWR FLY-BY INDICATED WHAT APPEARED TO BE A NORMAL GEAR INDICATION FOR LNDG. WE THEN HEADED N ON AN EXTENDED DOWNWIND. I FLEW THE AIRPLANE, THE OTHER PLT PULLED OUT THE EMER GEAR EXTENSION CHKLIST. CAREFUL REVIEW OF THE CHKLIST SHOWED THAT ALL ITEMS HAD BEEN COMPLETED. RWY 22 WAS SELECTED TO GIVE A L XWIND. THE CTLR DECLARED AN EMER FOR US. ON FINAL, THE R MAIN GEAR LIGHT ILLUMINATED FOR A FRACTION OF A SECOND. LNDG CONFIRMED THAT THE R MAIN GEAR WAS DOWN AND LOCKED. IN RETROSPECT CERTAIN INACTION ON MY PART SHOULD HAVE BEEN AVOIDED. AT THE TIME OF THE EVENT, I SHOULD HAVE STATED, BIENNIAL FLT REVIEW IS OVER, WE WANT TO JUST GET THE ACFT AND OCCUPANTS ON GND SAFELY. I SHOULD HAVE DECLARED EMER, NOT TWR. OTHERWISE, AS A CREW, THE OTHER PLT AND MYSELF WORKED WELL TOGETHER TO RESOLVE THE PROB BY DIVIDING THE WORK TO BE DONE AND DOING IT. FELT GOOD CRM SKILLS DISPLAYED AT THIS TIME.
