The NTSB's narrative final · quoted from the NTSB record
The student pilot made several takeoffs and landings prior to departing the traffic pattern. Witnesses reported observing the airplane flying at an altitude of approximately 20 feet above the trees, and they reported that they did not hear the airplane's engine running. A witness stated that the airplane flew by her in a level attitude, and after the airplane cleared some power lines it started to descend. It then appeared that the airplane's left wing impacted some trees before it nosed down into the trees. Continuity was established to all of the 1968-model Beech Musketeer's flight controls. Examination of the engine oil pressure and suction screens revealed the presence of metal particles, shavings and flakes. The oil pressure relief valve plug, spring, and ball were removed. The ball had metal adhering to it, and the ball seat was contaminated with metal, which according to the manufacturer representative, "may have prevented the ball from contacting the seat." A large amount of sludge was found inside of the crankshaft. A teardown examination of the engine revealed evidence of a lack of lubrication. A review of the airplane's maintenance records revealed that the engine's last oil change was on July 2, 1999, at a total airplane and engine time of 1,665.0 hours. There was no record that the oil suction screen or oil pressure screens were cleaned during that oil change. The last documented cleaning of the oil screens was December 1, 1996. At the time of the accident, the airplane had accumulated a total time of 1,680.92 hours and the engine had never undergone an overhaul. The engine's operating manual states that "at each 100 hour inspection remove suction screen. Inspect for metal particles; clean and reinstall. Inspect and clean pressure screen every 25 hours."
