(-23) On March 25, 2000, at 1127 MST, a Cessna 152 ii, N6251B, registered to great southwest aviation, impacted the ground 10.8 NM, northeast of chisom VORTAC, while on a training flight. Visual meteorological conditions prevailed at the time and a VFR flight plan was not on file. The aircraft was demolished and the student pilot was fataly injured. The fligth originated at Roswell industrial airport, Roswell, new Mexico, on March 25, 2000, at 1055 MST. (.4)wreckage and impact information: the airplane was found (9.6 NM from row at 017 degrees) in a flat pasture (elevation 3,540 feet, N33 degrees, 26.12'; W104 degrees, 28.47'). The soil was very dry and hard. There was no ground scar leading to the airplane; the longitudial axis was approx. 015 degrees. The wings were level, and their leading edges were compressed aft in accordion like fashion. The engine was buried in the ground and its accessory section had been displaced into the cockpit area. The instrument panel had been pulverized. The fuselage was found compressed into the cockpit, wrinkled, and nearly separated from just behind the wings. The empennage was was found with little damage, and partially separated from the fuselage. All of the airplane's major components were accounted for at the accident site. The flight control surfaces were all identified. Control cable continuity was established to the ailerons; however, control cable continuity could only be established from the rudder and horizontal stabilizer to the aft cabin area. The flap actuator in the right wing indicated that the wing flaps were up. Both wing fuel tanks exhibited forward bulging deformations accompanied by holes through their respective wings. Witnesses reported "strong fuel smells" when they first approached the airplane. The engine controls, mixture and throttle, were found full forward. The carburetor heat was found full forward in the off position. The propeller was separated from the engine, and 1/3 of the propeller flange was broken off. Both propeller blades displayed chordwise striations (one blade also had 45 degree striations); both blades were bent aft, and/or "s" twisted; both blades had significant paint removed from mechanical abrasion. The oil slinger was impact damaged and catching on a broken section of the nose case. When this was cleared, the engine's crankshaft rotated freely, had good "thumb" compression on all cylinders, and continuity was demonstrated through the valve train and all accessories. The left magneto rotated by hand and produced good spark on all leads. The right magneto rotated by hand, its impulse coupling-clicked, but the magneto did not spark due to an impact damage cap and leads. The airplane was found 1.8 NM and 080 degrees from the pilot's house. A camera was found in the cockpit area; the film cassette was determined to be damaged and attempts to recover pictures from the half exposed roll were unsuccessful. No preimpact engine or airframe anomalies, which might have affected the airplane's performance, were identified. There was no evidence of pre or postimpact fire.
