Narrative:
En route from cgi to mwa, the first officer and I heard a strange noise. We looked down at the hydraulic pressure gauges and the right read zero. Approximately 30 seconds later, the left pressure fell to zero. We climbed to 7000 ft MSL to contact company. After consulting with company, we tried to lower the gear normally. Nothing happened. We then spoke with company again and we decided to run the emergency gear extension checklist. At this time we declared an emergency. We manually extended the gear by pumping it down. We informed center that we would need the crash fire rescue equipment trucks standing by. We informed the passenger and company of what was happening and what our intentions were. The first officer and I talked about what was happening and went over our plan of action. We got vectored onto the approach and subsequently landed at mwa without incident. I had the first officer deplane the passenger while I secured the airplane. On postflt inspection it appeared that our right hydraulic line ruptured, which bled off all of our hydraulic fluid.
