Are 4WD/AWD components, such as driveshafts or hydraulic hoses, permitted to pass through the firewall (i.e. through the region bounded by RRH/ALC/BLC)?
4WD/AWD components may penetrate the firewall. The protective cover over the component(s) must be sealed to the firewall, similar to seat belt extensions, such that no fuel or fire may pass into the cockpit.
