Incident at ST. JOHN'S INTL NL (CYYT)

Summary

2015-06-23: Update from Maintenance & Manufacturing: Number 1 engine fuel pressure low caution illuminated several times during flight. On one occasion the engine 1 failure audio was heard accompanied by a brief flash of the engine out warning light. A roll on landing was carried out without incident. Health and Usage Management System (HUMS) determined that it was a momentary flameout and the engine automatically relit immediately. The following is a list of parts changed on the aircraft for snag isolation; the Fuel Filter was replaced and is in quarantine, the Breakaway Valve (slight wear was found), the Check Valve, the Fuel Manifold (slight wear found), and the Fuel Selector Valve. The aircraft has had a series of test flights and it is believed that the defect was caused by the fuel selector valve, based on the valve history in the S-76 fleet. The aircraft is being returned to service.
