So what happened? The aircraft began to roll and it sounds like they were performing a slip to keep it straight and level?
It is a roll problem, and if we want to know the reason we must see the result of the problem, the pilot says he has to use his left AILERON and his Wright RUDDER and this is the procedure to maintain st & lvl when u have your Wright engine off during a flight, but since the pilot didn’t not say that he had an engine problem so I think it is one of tow problems,
1st it is a problem with one of the AILERONs because it a roll problem and what makes the plane rolls is the AILERONs so he is trying to correct his turn or roll but he couldn’t,
2ed is that one of the engines had a problem which is not that bad one that makes the engine under power, but if this choice was right, then why didn’t the pilot saw that on the engine instrument?
