On March 28, 2000, at 1115 central standard time, a Cessna 152 airplane, N94912, was substantially damaged when it impacted the ground while maneuvering near Decatur, Texas. The two occupants, a flight instructor and a student pilot, received minor injuries. The airplane was operated by Delta Aeronautics Inc., of Fort Worth, Texas, under 14 Code of Federal Regulations Part 91 as a dual instructional flight. Visual meteorological conditions prevailed and no flight plan was filed for the local flight that departed from the Fort Worth Meacham International Airport, Fort Worth, Texas, at 1030. According to the student pilot, the preflight inspection and pre-takeoff engine run-up did not reveal any anomalies with the airplane. The instructor was demonstrating a simulated engine failure and forced landing. The student reported that as the airplane descended "close to the ground" the instructor "added power, the engine responded, and immediately the aircraft became unstable and he lost control." Subsequently, the airplane contacted the ground and came to rest upright. The instructor was unconscious for a short time immediately following the accident and does not recall the event. A witness reported to an FAA inspector that the airplane appeared to be practicing emergency landings. The witness further reported that the airplane was flying from the east to the west and was moving "slower and slower" until finally it "stalled." He added that the airplane's left wing impacted the ground, followed by the nose. The FAA inspector, who examined the airplane, reported that both wings incurred structural damage, the propeller separated from the engine crankshaft, and the nose landing gear folded aft. He added that the flaps were found extended to 30 degrees.
