Aircraft Equipment Problem Less Severe
Flight Crew Returned To Departure Airport; General Maintenance Action
Aircraft
At gear retraction; the right main gear light showed gear unsafe. We followed the Abnormal check-list 'Gear unsafe light(s) illuminates after gear retraction'. We contacted Maintenance Control. We were directed to return and we landed uneventfully; below maximum landing weight; and returned to the gate. We were assigned a new aircraft. This was a mechanical issue. Maintenance has not informed me why this occurred.
B717 Captain reports receiving a right main gear unsafe indication after gear retraction. Abnormal checklist procedures are complied with and flight returns to departure airport.
