Analysis

The student pilot and passenger changed the engine oil just prior to attempting the takeoff. The oil was drained on the ground on the airport where the aircraft was parked. Examination of the oil, disclosed that metal shavings were present in the drained oil. Further examination of the aircraft disclosed that metal shavings were also present inside the engine when it was disassembled. The examination also found rust in the cylinder walls along with the fractured rings from numbers 2 and 3 pistons. The annual inspection or recent maintenance data was not determined.
