From the report:
"After the second touch-and-go, all valid Weight on Wheels (WoW) sensors indicated the MA was on the ground, and the MA transitioned to the “on ground” flight control law (i.e., automated ground-operation mode causing the MA to operate as though it was on the ground when flying). However, because it was actually airborne, the MA was uncontrollable."
On projects that I've worked on we used the WOW switches as a backup and primarily used air speed to determine if the plane was on the ground or not. I'm surprised that the plane was able to enter "on ground" control law while it was still flying based only on the status of the WOW switches. It seems to me like there should be some additional checks before entering a state that makes the aircraft "uncontrollable".
