Aircraft
Just before leveling at cruise altitude the Right Engine failed. It rolled back slowly over about 10 seconds. Memory items were followed and ATC contacted. We diverted and landed single engine at the nearest suitable airport. I suspect the right engine was fuel starved. Upon engine start; prior to departure; the FUEL 2 LOW PRESS annunciator remained illuminated. The PM and I reviewed the checklists; and then consulted the MEL. The MEL also referred us to the AFM. We reviewed the AFM together. I called Maintenance; and they walked me through the MEL procedure and the associated paperwork. Maintenance indicated everything was in order; I emailed pictures of the maintenance log to Maintenance Control and the passengers were informed of the reason for the delay. The AFM checklist was reviewed and we departed with no other abnormalities until the flameout.The PNF and I reviewed the procedure together and with Maintenance again after landing. I have operated previously with the same MEL. We don't see anything we missed.
We started engines and noticed No. 2 Fuel Pressure light remained illuminated. We double checked switches/circuit breakers and observed them in their normal positions. We deduced that our No. 2 boost pump was inoperative. The Captain called Maintenance and they confirmed this. In conferring with Maintenance the boost pump was written up; The AFM and MEL limitations were observed and an Inop sticker put in place. We then departed and; upon reaching FL410; the right engine began to roll back. Memory items were executed by the captain and the engine out checklist called for. AFM and MEL procedures were followed and pre and post- indecent between crew members; we could not identify anything that we could have done differently that would have prevented this incident.
After completing the appropriate MEL tasks to depart with an inoperative No 2 fuel boost pump inoperative the flight crew of a BAE-125 suffered a flame out at FL410 and diverted to the nearest suitable airport for maintenance.
