TEMPORARY LOSS OF ACFT CTL IN SIMULATED SINGLE ENG TRAINING.

Narrative

IN SUM: AN INSTRUCTOR WITH STUDENT SET UP A SIMULATED SINGLE ENG PROB IN A CESSNA 310. THE STUDENT DECIDED TO FEATHER THE 'FAILED' R ENG; SO THE INSTRUCTOR SET UP A SIMULATED FEATHER SIT. THE STUDENT AT NO TIME RETRIMMED THE ACFT FOR SINGLE ENG FLT. AT GS INTERCEPTION; THE LNDG GEAR WAS EXTENDED AND THE FLAPS WERE LEFT UP PER FLT MANUAL RECOMMENDATIONS. A STOP AND GO LNDG WAS PLANNED. DURING THE LNDG FLARE; THE STUDENT ALLOWED THE ACFT TO YAW TO THE L. THE INSTRUCTOR CALLED FOR MORE R RUDDER; THEN GOT ON THE RUDDER TO HELP. THE INSTRUCTOR FOUND THAT THE R RUDDER WAS ALREADY TO THE FIREWALL. THE INSTRUCTOR CALLED FOR A GAR AND PWR WAS ADVANCED ON BOTH ENGS. THE RUDDER PROB DID NOT GO AWAY. THE LNDG GEAR WAS RETRACTED AND AN EMER WAS DECLARED. AS SOON AS THE INSTRUCTOR GOT OFF OF THE RUDDER PEDAL; THE BALL WENT BACK TO THE CTR AND THE PROB DISAPPEARED. A NORMAL LNDG WAS THEN MADE WITH THE R LNDG GEAR DOOR STILL EXTENDED. THERE WAS NO ACFT DAMAGE AND THE CTLS WORKED PROPERLY. THE ACFT OWNER (NOT THE RPTR) THINKS THAT THIS WAS A 'VMC PROB;' THE RPTR LET THE AIRSPD GET TOO LOW FOR THE CONFIGN. THE RPTR REALIZES THAT HE SHOULD HAVE REDUCED THE PWR ON THE R ENG WHEN THE ACFT BECAME NEARLY UNCTLABLE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR HAS BEEN UNABLE TO FLY THE ACFT TO DETERMINE THE PROB WITH THE CTLS AS THE OWNER HAS TAKEN THE ACFT OFF OF THE LINE. THE ACFT WAS TRIMMED UP FOR NORMAL 2-ENG FLT DURING THE ENTIRE EPISODE. THE RPTR THINKS THAT THIS MAY HAVE BEEN A 'VMC PROB.'
