It is not always practical or legal to remove the right side yoke. For pt91 maybe, but for pt135 there are all kinds of FAA hoops to go through to maybe get that approved. And the loss of one paying passenger can make the difference on whether the flight is profitable or not. We’re not talking about pt121 airlines that have deep pockets and government bankruptcy protection. This is such a rare occurrence in pt135 ops that the last thing that is needed is some bureaucratic knee jerk rule to make flight operations that much more difficult. Unless a passenger has a previous attainable record of misbehavior on airplanes, there is not much that can be done to prevent this. The fact that the plane still landed safely, and that this is the first such occurrence I have heard of in pt135 ops since 9/11, I see little need for further worthless TSA regulation.
