## Discrepancy

THE ISSUE HAPPENS SOMETIMES. DURING CLIMB OUT AROUND 14,000FT TO 20,000FT THE LEFT ENGINE LOST THRUST ASSOCIATED WITH N1, ITT, N2, AND FUEL FLOW INDICATION CHANGE. FUEL COMPUTER LIGHT DIDN`T APPEAR ON THE ANNUNCIATOR PANEL. THE ISSUE STOPPED WHEN BELOW 12,000FT AND ENGINE OPS RETURNED TO NORMAL.
