A BAE 4100 WITH TPE331-14 ENGS TAXIED INTO POS AND HOLD. PRIOR TO TKOF WITH ENGS IN STEADY STATE IDLE; THE R ENG FLAMED OUT WITH ACCOMPANYING SMOKE.

Narrative

TAXIED OUT FOR DEP. WHILE HOLDING IN POS ON RWY 12L WAITING FOR TKOF CLRNC; THE R ENG FLAMED OUT (QUIT). SMOKE WAS OBSERVED BY ANOTHER ACFT AND TWR NOTIFIED CFR. WE DETERMINED THAT THERE WAS NO FIRE OR DAMAGE VISUALLY FROM THE CABIN AND HAD NO INDICATION ON THE FLT DECK. THE ENG WAS SECURED AND WE TAXIED THE ACFT CLR OF THE RWY. CFR TRUCKS MET US ON THE TXWY P HOLDING PAD AND EXTERNALLY VERIFIED THAT THERE WAS NO DAMAGE OR FIRE. AFTER COMPLETING COMPANY NOTIFICATION CALLS; WE TAXIED BACK TO THE RAMP AND DEPLANED. IT NEEDS TO BE MENTIONED THAT THIS TYPE OF SPONTANEOUS ENG FLAMEOUT IS A RELATIVELY COMMON OCCURRENCE (ACCORDING TO COMPANY MAINT). CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ACFT HAD 2 TPE331- 14GR/HR ENGS; AND BELIEVES THE MAINT ACTION WAS ADJUSTMENT OF THE MECHANICAL FUEL CTL. THE RPTR SAID THAT 2 OTHER INCIDENTS OF ENG FLAMEOUT ARE KNOWN. ONE WAS WITH THE ENG REVERSING; AND THE OTHER WAS AT STEADY STATE IDLE PWR. THE RPTR STATED THE FIX ON ONE WAS PWR LEVER RIGGING; AND THE OTHER INVOLVED TWEAKING THE MECHANICAL FUEL CTL. THE RPTR SAID THIS ENG HAS AN INTEGRATED ELECTRONIC CTL; BUT RULES OUT PROBS WITH THIS UNIT. THE RPTR SAID THESE ENGS ARE FARMED OUT FOR HVY MAINT AND OVERHAUL AND NOT ACCOMPLISHED BY THE ACR.
