Timbo - similar event - 777 crew loses an engine. Lands SE. No problem.

At the post incident briefing - "very nice job. We just have one question, why'd you turn the TAC off?"

"SE requires the TAC off. That's the procedure."

Nope, that's how they taught it. Showed one TAC engine failure then all others were done with the TAC OFF. Guy thought TAC OFF was required. Negative transfer. Oops. Now training shows TAC OFF then the rest of the training is done with the TAC ON.
