OOSC, Part II, Item 3. Coupling Devices, c. Pintle Hook - Uncoupled

Was inspecting a truck pulling a set of doubles. The full trailer which was sitting on a converter dolly was not connected to the semi-trailer pulling it. The drawbar was not in the pintle hook and was wedged under the bumper of the semi-trailer. It appears the drawbar eye had been resting on the bumper of the semitrailer but when driver was pulled in for inspection, it slid off the bumper and went under it. It was not connected when they pulled into the scale. When I referred to the OOSC, there was nothing advising that a full trailer not connected was an OOS condition. The OOSC sections that cover pintle hooks, drawbar eye, etc. only discuss the mounting and structural integrity of pintle hook, drawbar eye, towbars, etc. There is an item in the OOSC for "Kingpin not engaged" however this was not a kingpin, just a pintle hook and converter dolly with a drawbar eye and tongue.

Although I have never seen this before in my 20 years of inspecting and no one ever expects to see it, I feel that it is necessary to have it in the OOSC that a full trailer not connected to the pulling vehicle would be an OOS condition. The only thing holding the full trailer was the safety chains were the safety chains.

Adding "Full trailer not properly connected" as an OOS criteria as this situation presents an imminent hazard to the general public.
