CHP - Chowchilla River Commercial Vehicle Enforcement Facility:

While completing a North American Standard Level I Inspection, one of our senior inspectors noticed the rear of the trailer was leaning towards the left-side (driver side). After concluding the underneath inspection, he observed a crack in the right-side frame siderail web around the radius and into the bottom flange behind the center equalizer placing the vehicle out of service due to the collapsing frame. The North American Standard OUT-OF-SERVICE CRITERIA section 393.201(a) states, “any cracked, loose, sagging or broken frame siderail permitting shifting of the body onto moving parts or other condition indicating an imminent collapse of the frame”.
