I can see that the tail boom is of a horn balance design. Is it possible that this could contribute to the feather 'self-deploying' once unlocked given the right aerodynamic pressure?
Also I believe the actuator is pneumatic. Would this provide less resistance to 'self-deployment' than hydraulics?
Thinking about it some more, the pressure on the horn wouldn't need to deploy the feather but could place enough pressure either side of the pivot to break the boom about that point.
