## Discrepancy

APPROXIMATELY 30 MINUTES INTO THE FLIGHT, THE LT ENGINE DROPPED TO 15" MAP AND THEN RETURNED TO 36" MAP ~3 TIMES. AFTER ~10 MORE SECONDS THE LT ENGINE MAP DROPPED TO 0" AND THE POWER PERCENTAGE INDICATED 0 FOR ~20 SECONDS. THE LT ENGINE WAS SECURED AND THE AIRCRAFT DIVERTED TO KPWM. NO OBVIOUS DEFECTS OR LEAKS WERE NOTED DURING POST EVENT INSPECTION. POST EVENT GROUND RUNS WERE NORMAL. GARMIN AND DLU DATA FILES HAVE BEEN PROVIDED TO THE ENGINE MANUFACTURER FOR ANALYSIS. THE ENGINE AND ECU HARNESS HAVE BEEN RETURNED TO THE ENGINE MANUFACTURE FOR EVALUATION.
