## Discrepancy

AN EMERGENCY WAS DECLARED AND THE AIRCRAFT LANDED WITH ONE ENGINE. THE ENGINE HAS SINCE BEEN REMOVED FOR INSPECTION AND EVALUATION. RECOMMENDED THE REPLACEMENT OF THE W5 HARNESS, OSSD AND BOTH ELECTRONIC ENGINE CONTROL UNITS. THE N1 OVERSPEED SHUT-OFF DETECTOR P/N: 3034256-4 S/N: 16-162151-00732, W5 HARNESS P/N: 3034427-3 S/N: 16-162599-02772, ECU A P/N: 2119576-1011 S/N: 74-V0067, AND ECU B P/N: 2119576-1011 S/N: 94-V0108 WERE ALL REPLACED WITH REPAIRED OR NEW UNITS.
