Synopsis
The right main gear green light on a B767-200ER failed to illuminate after extension for landing. The flight crew declared an emergency but were convinced the problem was with the indicating system. Their convictions proved accurate upon landing.
Narrative
I was the pilot not flying. We had set up for the VOR approach; but had a visual on the runway and got recleared for a visual approach. Upon lowering the gear we noticed no indication for the right gear annunciator. I tested the the lights with negative results. The Captain broke off the approach and we climbed to 3;000 FT. We accomplished the QRH and declared an emergency with Approach. We also requested CFR. The Captain gave me control of the aircraft and he contacted Operations and Maintenance.We were convinced that the issue was a indication issue only. There was no other warning lights or EICAS messages. The Captain took back control of the aircraft. We flew a fly-by at 500 FT. Tower relayed that the main gear looked normal. With no other indications of the gear not down we flew a tight left pattern back to the runway and landed uneventfully. The gear was pinned by Maintenance and the aircraft was towed to the gate. Total time between the first approach and landing [was] about 25 minutes.
Second reporter narrative
At no time did we have an amber 'Gear' light. At no time did we have an EICAS 'Gear' message. There was no adverse yaw or unusual noise or vibration. We believed the gear was in fact down and locked. As a precaution we elected to do a flyby so Tower/Ground personnel could look at landing gear.
