## Discrepancy

ON CLIMB OUT EGT EXCEED 925' ON #2 ENGINE (ENGINE EXCEEDENCES PAGE SHOWS PEAK 957'; RED 950' FOR 7.8S)<[01] PERFORMED GVI OF #2 ENGINE INLET AND EXHAUST; INSPECTED EGT PROBS CONNECTORS AND NO DEFFECTS FOUND. PER POWERPLANT ENGINEERING TSR TRACKING #2024005074 OVERTEMP OCCURRED ON HIGH-PERFORMANCE TAKEOFF (NEAR 0 DE-RATE) IN HOT AMBIENT CONDITIONS; THE ENGINE CURRENTLY HAS LOW EGT MARGIN. ENGINEERING WOULD CONSIDER THE CAUSE OF THIS EXCEEDANCE DUE TO ENGINE DETERIORATION; PER AMM 71-00-00-800-804-F00 THIS SHOULD BE LOGGED AS 1 OF 10 ALLOWABLE EGT OVER TEMPERATURES. PLANNED ENGINE WASH WILL BE THE CORRECTIVE ACTION FOR THIS CONDITION. OK TO CONTINUE PER TLD AUTH # 205371.
