Narrative:

At some point after application of takeoff power, the fuel control unit power lever for the left engine came off. The problem became known passing 400' AGL when the flaps were raised, flow controls turned on and a power reduction was attempted. The right engine responded normally to power lever movements; however, the left engine was set at 100% torque, 650 degrees itt and 100% RPM and would not respond to power lever movements. An emergency was declared with cha approach control and vectors for the ILS to runway 20 were requested. Approach control issued a climb to 3000' and a turn to 060 degrees. The checklist was consulted, however there is no emergency or abnormal checklist for an engine failure with high power setting and no response to power lever movement. The srl was turned off and itt dropped to 520-540 degrees itt as normal. The ttl was turned off and torque immediately went to 104%, so the ttl and srl were turned back on and torque dropped to 100% and itt returned to 650 degrees redline. The aircraft was stabilized with the left engine at maximum power and the right engine at flight idle. A turn to intercept the localizer for the ILS was initiated and the procedures for shutdown of the left engine were discussed. The aircraft was configured for landing with landing gear down and flaps 20 degrees selected. The localizer for runway 20 was intercepted and the aircraft stabilized on the localizer and G/south for the approach. Visibility reference to the ground was gained at approximately 700' AGL. The aircraft was landed on centerline and the feather fuel shutoff lever was pulled for the left engine. The aircraft immediately swerved to the right and efforts to keep the aircraft on the runway were unsuccessful. The same problem has happened at least once before with the same result (i.e., the aircraft departed the runway). There are no published emergency or abnormal procedures or checklists for this type problem. Both pilots involved have attended formal manufacturer ground school and simulator training and this type failure is not addressed in the ground school or simulator syllabus.

Title: CPR SMT FLT CREW EXPERIENCES OUT OF CTL ENGINE.

Narrative: AT SOME POINT AFTER APPLICATION OF TKOF PWR, THE FUEL CTL UNIT PWR LEVER FOR THE LEFT ENG CAME OFF. THE PROB BECAME KNOWN PASSING 400' AGL WHEN THE FLAPS WERE RAISED, FLOW CTLS TURNED ON AND A PWR REDUCTION WAS ATTEMPTED. THE RIGHT ENG RESPONDED NORMALLY TO PWR LEVER MOVEMENTS; HOWEVER, THE LEFT ENG WAS SET AT 100% TORQUE, 650 DEGS ITT AND 100% RPM AND WOULD NOT RESPOND TO PWR LEVER MOVEMENTS. AN EMER WAS DECLARED WITH CHA APCH CTL AND VECTORS FOR THE ILS TO RWY 20 WERE REQUESTED. APCH CTL ISSUED A CLB TO 3000' AND A TURN TO 060 DEGS. THE CHKLIST WAS CONSULTED, HOWEVER THERE IS NO EMER OR ABNORMAL CHKLIST FOR AN ENG FAILURE WITH HIGH PWR SETTING AND NO RESPONSE TO PWR LEVER MOVEMENT. THE SRL WAS TURNED OFF AND ITT DROPPED TO 520-540 DEGS ITT AS NORMAL. THE TTL WAS TURNED OFF AND TORQUE IMMEDIATELY WENT TO 104%, SO THE TTL AND SRL WERE TURNED BACK ON AND TORQUE DROPPED TO 100% AND ITT RETURNED TO 650 DEGS REDLINE. THE ACFT WAS STABILIZED WITH THE LEFT ENG AT MAX PWR AND THE RIGHT ENG AT FLT IDLE. A TURN TO INTERCEPT THE LOC FOR THE ILS WAS INITIATED AND THE PROCS FOR SHUTDOWN OF THE LEFT ENG WERE DISCUSSED. THE ACFT WAS CONFIGURED FOR LNDG WITH LNDG GEAR DOWN AND FLAPS 20 DEGS SELECTED. THE LOC FOR RWY 20 WAS INTERCEPTED AND THE ACFT STABILIZED ON THE LOC AND G/S FOR THE APCH. VIS REF TO THE GND WAS GAINED AT APPROX 700' AGL. THE ACFT WAS LANDED ON CENTERLINE AND THE FEATHER FUEL SHUTOFF LEVER WAS PULLED FOR THE LEFT ENG. THE ACFT IMMEDIATELY SWERVED TO THE RIGHT AND EFFORTS TO KEEP THE ACFT ON THE RWY WERE UNSUCCESSFUL. THE SAME PROB HAS HAPPENED AT LEAST ONCE BEFORE WITH THE SAME RESULT (I.E., THE ACFT DEPARTED THE RWY). THERE ARE NO PUBLISHED EMER OR ABNORMAL PROCS OR CHKLISTS FOR THIS TYPE PROB. BOTH PLTS INVOLVED HAVE ATTENDED FORMAL MANUFACTURER GND SCHOOL AND SIMULATOR TRNING AND THIS TYPE FAILURE IS NOT ADDRESSED IN THE GND SCHOOL OR SIMULATOR SYLLABUS.
