Narrative:

On approach into mci, we received an unsafe gear indication on the right main landing gear. The gear was cycled successfully, ran the QRH for manual gear extension and gear still showed unsafe (red light on r-hand main). We complied with all QRH checklist items. The gear could not be determined to be down and locked with the landing gear viewer. A tower fly-by was accomplished and tower advised us that the r-hand main gear appeared to be partially extended. After, we declared an emergency and had the flight attendants prepare the cabin for an emergency landing. The landing was uneventful. We stopped on the runway and had the gear pins installed then taxied to the gate.
