## Probable cause

The improper maintenance decision to adjust the engine oil pressure regulator valve in response to high oil pressure indications rather than to properly troubleshoot the anomaly, which then allowed an existing oil supply path blockage to increase and led to the eventual insufficient lubrication of the compressor section No. 2 bearing and the subsequent loss of engine power. Contributing to the incident was an engine oil lubrication system anomaly of unknown origin.
