## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

ON SEPTEMBER 22, 2017, N618WF INITIATED A DEPARTURE FROM KMEZ (MENA MOUNTAIN MUNICIPAL AIRPORT, AR) FOR KPHF (NEWPORT ? WILLIAMSBURG INTERNATIONAL AIRPORT, VA).

THE COMPANY DIRECTOR OF MAINTENANCE, A MAINTENANCE TECHNICIAN; A BOMBARDIER TECHNICAL REPRESENTATIVE AND ROLLS ROYCE MAINTENANCE TECHNICIANS RESPONDED TO THE AIRCRAFT FOR THE INVESTIGATION. THE NTSB, AIRFRAME, ENGINE AND COMPONENT MANUFACTURER ENGINEERING HELD CONFERENCE CALLS BETWEEN SEPTEMBER 25 AND OCTOBER 11, 2017 TO SUPPORT AND DIRECT THE INVESTIGATION.

DURING THE INVESTIGATION THE FOLLOWING ITEMS WERE IDENTIFIED:

THE LEFT ENGINE VARIABLE STATOR VANE ACTUATOR (VSVA) P/N 2606 MK3 HAD A DUAL LANE LVDT FAULT CAUSING THE ELECTRONIC ENGINE CONTROL (EEC) LOGIC TO SHUT OFF FUEL TO THE ENGINE.

A LEAK IN THE AVIONICS COOLING FAN SUCTION ?U? DUCT AT THE FAN MOTOR MANIFOLD CAUSED FOUR OF THE SIX HONEYWELL DU-870 PRIMARY INSTRUMENT AND NAVIGATION DISPLAY UNITS TO FAIL DUE TO OVERHEAT.

A DCPC CONTACTOR-K3(PN MFR58657-0027) FAILED CLOSED ON AIRCRAFT POWER UP AT KMEZ CAUSING THE ?GEN 1 FAIL? CYAN MESSAGE, ?L BLEED FAULT? CYAN MESSAGE, ?RUD AUTHORITY LOW? AMBER CAS MESSAGE; AND RUDDER LIMITER FAIL AMBER CAS TO BE DISPLAYED PRIOR TO DEPARTURE OR DURING THE FLIGHT TO KPHF.

THE INVESTIGATION CONTINUES INTO THE COMPONENT ANALYSIS PHASE. THIS INCLUDES THE LEACH K3 RELAY WITH UTAS, THE FOUR DU-870 DISPLAY UNITS WITH HONEYWELL AND THE TWO VSVAS WITH ROLLS ROYCE. THESE ACTIVITIES WILL BE MONITORED BY BOMBARDIER AND THE NTSB.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
