Just to clarify things, I NEVER said let the "office" make the decisions, but consulting with them and accommodating the best way to proceed. Using AS262 is a giant red herring, a specialty of flarepilot.
In a quad, following simple engine failure, continuing has been SOP for decades, FAR 121 considers it, airlines continue when conditions permit, and is fine. Flying around with a stab trim problem was wrong, flight control malfunctions on a plane with a history of problemsm are very different from simple engine failure.
Immediate return or landing on a quad is applied twin engine thinking.
