Narrative:

Pre-flight showed all fluids including hydraulic fluid in normal range and right landing light was out. After take-off landing gear did not retract properly. Commenced troubleshooting after 1000 ft and continued to troubleshoot while on vectors and cleared to 2000 ft. While troubleshooting an inadvertent altitude loss of from 2000 ft to one 1500 ft was experienced. Climb back to 2000 ft was accomplished without delay. Landing gear malfunction resulted in the landing gear being 'blown down' per emergency checklist. Three green down and locked lights observed and red gear unlocked light extinguished. Landing completed without incident. Post flight inspection showed hydraulic fluid leaking from station 218 under fuselage and hydraulic sight reservoir was empty. Runway conditions dry and weather was VFR.
