## Discrepancy

PILOTS NOTICED A SIGNIFICANT SPIKE IN LEFT ENGINE OIL PRESSURE. OIL PRESSURE WOULD FLUCTUATE WELL PAST RED-LINE AND SPIKED AS HIGH AS MAX TRANSIENT OIL PRESSURE.  A LOSE CONNECTOR WAS FOUND TO BE THE ISSUE. THE CONNECTOR WAS CLEANED, TIGHTENED, AND SAFETY WIRED. THIS CORRECTED THE PROBLEM.
