Feature B

Feature B - Horizontal Torque Box
In Feature B, the horizontal torque box is a stiffener on the sidewall of the uplock support.

The box has a wall thickness of 0.120 inches joining into the side wall with a thickness of 0.160 inches.

Stress concentrations at the joint are reduced by providing a generous fillet on the wall-box joint and the interior corners of the torque box.

Feature B does need to be changed.
