I was required to shut down an engine in a 310 on my checkride but that was at least 4000ft over 1000ft terrain and that particular aircraft had an unfeathering accumulator without which the examiner would have been content with a demonstration. I did a few shutdowns training on a four-engined turboprop but the company strictly prohibited that for twins. As the remaining Rotax on the Tecnam is sufficient to keep a Katana or similar-sized two-seater aloft it does not seem prudent to task it with pulling a much bigger airframe around.
