Analysis

The homebuilt velocity & a Boeing 727 were both operating in the tca in VMC with radio & radar contact established with ATC, and both were being advised of each other's position and heading. Both airplanes were on a southeasterly heading, with the B-727 overtaking the homebuilt higher and slightly to the left. The B-727 reported having the velocity in sight, and was instructed to maintain visual separation and cleared to descend. At the time the B-727 passed over the velocity, it was at 10,000 ft and the velocity had just started a descent from 9,500 ft. the velocity continued a southeasterly heading. Aprx 3-1/2 min later the velocity pilot broadcasted a mayday that he was out of control. He then said he was upside down. His last transmission was '...I hit the prop wash the vortex...' Wake turbulence hazards, pilot awareness & avoidance procedures are discussed in the airman's information manual.
