RSC shall deduct the amount of the RSC consultant’s travel expenses and fee from the amount RSC owes the retail dealer if the consultant is required to make a return visit to the retail dealer for inspection for either of the following reasons: (a) the vehicle is not ready for inspection, or (b) the modifications have not been completed in accordance with these rules. The retail dealer must cancel the appointment at least twenty-four hours in advance in order to avoid the deduction.

(5) Rework inspection. RSC may require the vehicle modification inspector to perform an inspection of rework completed on a consumer’s modified vehicle within the first ninety days following delivery of the completed vehicle to the consumer. If it is determined that the cause of the rework is dealer installation or workmanship, the retail dealer shall be required to pay for the cost of the inspection, including the fee and travel expenses of the inspector and any reasonable costs incurred by the consumer as a result of the rework.

(K) Inspection of vehicles prior to conversion. Vehicles shall be inspected by an RSC representative or designee before authorizing a modification for the installation of a wheelchair or scooter handling device. The RSC representative or designee shall inspect the vehicle to insure the structural integrity of the vehicle; and that the vehicle design is appropriate to accept the recommended device.

(L) Applicability to other rules. The requirements contained in this rule shall also apply to rules 3304-6-05 to 3304-6-15 of the Administrative Code, as applicable. When the requirements contained in rules 3304-6-05 to 3304-6-15 exceed those in this rule, the requirements in rules 3304-6-05 to 3304-6-15 shall govern.
