On November 11, 1995, approximately 1735 central standard time, a Lodge RV-4, N30RV, registered to, and operated by the pilot as a Title 14 CFR Part 91 personal flight, was destroyed during a forced landing following a loss of power. Visual meteorological conditions prevailed and no flight plan was filed. The private pilot-in-command and his passenger sustained serious injuries. The flight originated from Aero Country Airpark, McKinney, Texas, about 5 minutes prior to the accident. The pilot reported that, after takeoff he "climbed to 1,800 feet MSL and leveled off." During a turn to the left, "the engine stopped." He further reported that, "seconds-later the aircraft stalled and began rolling inverted." He stated that, he "over reacted to the right and the aircraft stalled again." After the second stall, he "pushed the stick forward to regain airspeed and control." He then, "managed to get the aircraft almost level" [and] out of a dive, when contact with the ground was made." A witness observed the airplane "losing altitude fast" and "leveling off just prior to" ground impact. Examination of the airplane by a FAA inspector revealed the following: The right wing main fuel tank did not have usable fuel, and the fuel found in the left tank measured 1/2 inch on a measuring stick. Also, the fuel selector handle was found in the "right main open" position and both fuel quantity gauges indicated "near" empty. Additionally, the crankshaft was rotated and continuity was established through the accessory gears. All four cylinders had compression and valve action, and the magnetos produced spark through all wire leads when rotated by hand. No engine defects were observed.
