(-23) Aircraft was on a maintenance test flight at khnd for landing gear maintenance performed, engine driven hydraulic pump had been changed, and aircraft had been in maintenance pereviously for landing gear problems. The pilot extended the gear and did not receive gear down lights, he cycled the gear handle several times unsuccessfully extending the landing gear. The pilot then tried to extend the landing gear using the emergency landing gear extension handle and he found that he was still unable to get a down and locked indication for the main landing gear. He contacted the air traffic control tower and completed a fly-by in which the tower personnel confirmed his gear did not appear down and locked. After waiting for crash/rescue to arrive on scene the pilot completed the before landing checklist and found the flaps failed to extend as well. He completed a landing to runway 35R with the nose gear extended and the main gears retracted. After sliding approximately 1000' the aircraft left the runway to the west side and came to rest in the parallel drainage basin. Extensive damage was sustained during the accident sequence to the underside of the aircraft and the left horizontal stabilizer.
