A SAAB 340 IN INITIAL CLB DECLARED AN EMER AND DIVERTED DUE TO LOSS OF PWR IN #1 ENG CAUSED BY PULLING PWR LEVER BACK WITH AUTOFEATHER SYS ARMED.

Narrative

ON NOV/XA/98 I WAS THE CAPT ON ACR FLT XYZ. I WAS THE PNF. AT ACCELERATION ALT; THE FO CALLED FOR THE CLB CHK. I RAN THE CLB CHK TO THE AUTO COARSEN AND HELD THERE WAITING FOR 1500 FT AGL. AT ABOUT 600 FT OR SO; WE STARTED TO ENTER ICING CONDITIONS AND TURN ON THE ENG ANTI-ICE. ALMOST IMMEDIATELY WE GOT AN AIR VALVE LIGHT ON THE L ENG. THIS HAD BEEN WRITTEN UP IN NOVEMBER AND SIGNED OFF AS FIXED. I KNOW WHAT TO DO TO FIX THE PROB; IF IT CAN BE FIXED; SO I DO NOT GO TO THE QRH. BIG MISTAKE; BUT I WAS TRYING TO HURRY SO AS TO FIX THE PROB OR LET ATC KNOW WE HAD TO GET OUT OF ICING CONDITIONS. I TRY TO RESET THE ENG ANTI-ICE AND IT DOES NO GOOD. NOW I TELL THE FO I AM GOING TO PULL THE L PWR LEVER BACK SLOWLY TO SEE IF THIS WILL OPEN THE VALVE. WHEN I BRING THE PWR LEVER BACK UP THERE IS NO TORQUE ON THE ENG. NOW I GO TO THE QRH; BUT FIND NOTHING THAT ADDRESSES THIS PROB. THE FO AND I DISCUSS THE PROB AND DECIDE; SINCE WE DON'T KNOW WHAT IS GOING ON WITH THE ENG; TO SHUT THE ENG DOWN. WE DO THIS AND DECLARE AN EMER. WE LANDED AND TAXIED TO THE GATE WITHOUT ANY INCIDENT. IT WAS AFTER WE HAD PARKED AND WERE OFFLOADING THE PAX THAT I REALIZED I HAD NEVER FINISHED THE CLB CHKS AT 1500 FT AND TURNED OFF THE AUTO COARSEN. WHEN I HAD PULLED THE PWR LEVER BACK; I HAD AUTO COARSENED THE L ENG. THIS IS NOT MEANT AS AN EXCUSE; BUT I BELIEVE THAT HAVING HAD ONLY ABOUT 6 HRS SLEEP THE NIGHT BEFORE; DUE TO A SCHEDULED REDUCED REST OVERNIGHT; MAY HAVE HAD SOMETHING TO DO WITH ME NOT THINKING VERY WELL. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR SAID THAT DURING THE CLB THE RPTR WAS WAITING TO SWITCH OFF THE PROP AUTOFEATHER SYS AT 1500 FT WHEN AN ENG BLEED VALVE WARNING LIGHT CAME ON AT 600 FT. THE RPTR TOLD THE FO THAT THE RPTR KNEW THE FIX FOR THE BLEED LIGHT ON AND PULLED BACK ON THE PWR LEVER. THE RPTR SAID THE ACFT IMMEDIATELY LOST PWR ON #1 ENG AND WENT TO AUTOFEATHER. THE RPTR SAID AN EMER WAS DECLARED AND AN UNEVENTFUL LNDG WAS ACCOMPLISHED. THE RPTR STATED WHEN LEAVING THE ACFT IT OCCURRED TO THE RPTR THE AUTOFEATHER SWITCH WAS STILL ARMED AND WAS THE CAUSE OF THE PWR LOSS. THE RPTR SAID BOTH CREW MEMBERS WERE TIRED AND ONLY HAD 6 HRS SLEEP WITH 2 13-HR DUTY DAYS.
