Aircraft; Procedure
After two hour wait to get both nose gear tires replaced due to low pressure; departed gate. After takeoff; when gear retracted; had red light in main landing gear. Auto-spoiler DO NOT USE light came on at the same time. Complied with QRH procedures. When hydraulic pumps turned to LOW; gear door open light came on. When hydraulic pumps turned back to HIGH; gear door open light went out. Declared emergency and returned to the departure airport. After gear was lowered; all indications were normal. Landing was normal. Returned to gate and aircraft was taken out of service.
Pre-dawn sign in; waited 2 hours for Maintenance to change the nose tires. When gear retracted after take off right main landing gear indicated 'unsafe;' with gear doors closed. Also 'auto-spoiler do not use' light came on; both of these were previous write ups from the previous flight. When hydraulic pumps turned to low; 'gear door open light' came on. When hydraulic pumps were turned to high 'gear door open light' went out. Accomplished QRH procedure and declared an emergency and returned to the departure airport. Landing was normal. Aircraft was taken out of service. I declined to continue the trip out and back with different aircraft due to frustration and being tired.
During takeoff after a maintenance delay; an MD-83's right main landing gear indicated unsafe with the gear doors closed and the AUTOSPOILER DO NOT ARM light annunciated; so the QRH was completed; an emergency declared and the flight returned to the departure airport for an uneventful landing.
