Narrative:

Climbing out of 4500 ft right engine torque rose to over 110 percent. Aircraft yawed left. We shut down the right engine. Callback conversation with reporter revealed the following: the reporter flies the emb-120. This is all that he would say as he was not sure that this humble, sincere analyst was actually calling from NASA. The ASRS program will survive without his input. Supplemental information from acn 306552: I saw the #2 torque gauge go from 81 percent to zero percent, then jump back up to 83 percent. Suspecting an inadvertent feather of the #2 propeller, I looked up at the automatic-feather switch and found that it was still in the armed position. This switch should have been disarmed with the completion of the climb checklist. The captain and I suspected an over torque had occurred. We declared an emergency and returned to orlando.
