Captain called for gear down; upon moving the lever only 2 of the 3 landing gear lights illuminated. We proceeded to execute a fly by to have the tower visually verify all 3 landing gear were down. It appeared that only one of the two main landing gear were down. We then went northeast of the field to troubleshoot the issue and complete the QRH checklists. We successfully managed to get the remaining gear down and executed a second flyby. Landed without incident.
Convair 580 First Officer reported only one of the main landing gear dropped when selected down. The crew was able to successfully troubleshoot the problem and make an uneventful landing.
