Commission Approval of Manufactured Home Tie-Down Systems

PURPOSE: This rule describes the manner in which an approval of manufactured home tiedown systems may be obtained. (1) No person may sell, offer for sale, or as a business install or cause to be installed a manufactured home tie-down system unless the system has been approved in writing by the manager and the original or duplicate original of such approval is prominently displayed at the location where the system is sold, offered for sale, or offered for installation. (2) Applications for an approval shall be submitted to the manager and shall be executed by the owner or seller of the system on forms that shall be provided by the manager upon request. To be complete, the applications shall include: (A) The name and address of the applicant; (B) The name and address of all places of business which will be authorized by the applicant to sell or offer for sale, or install or offer to install the system for which the approval is sought; (C) The name and address of the manufacturer of the system for which the approval is sought; (D) A brief description of the legal organization of the manufacturer who will use the program, whether a Missouri corporation, foreign corporation, partnership, proprietorship, or other business organization; (E) If manufacturer is a corporation, a Certificate of Good Standing from the secretary of state and a copy of the corporation’s articles of incorporation and bylaws; (F) If manufacturer does business under a fictitious name, a copy of the fictitious name registration filed with the secretary of state; (G) If manufacturer has submitted the applicable information as set forth in subsections (2)(A)–(F) of this rule in a previous request for approval of manufacturing program, a statement that the information was previously submitted and remains unchanged; (H) If the information in subsections (2)(A)–(F) above is not available, or not applicable, a statement as to the reason the information is not submitted. The manager, in consult with staff counsel, shall determine if the request for approval can be processed without the required information; (I) A copy of the plans and specifications of the system for which the approval is sought. 1. Detailed drawings and the manufacturer’s installation manual of each type of anchor system and for each type of component for which approval is sought must accompany the submittal. A. Each drawing shall show model identification, all dimensions, types of welds or fastening, types of material, methods of securing strap, methods of attachment, orientation after installation in soil, direction(s) of applied load(s), and location of model number on the system and each component. B. Each drawing shall bear the seal of a registered professional engineer, registered in the state of Missouri. 2. Each anchor system model must be tested and certified by an authorized testing agency to be in conformance with the following anchoring standards and accepted engineering practice: A. Pullout tests shall be performed on three (3) samples of each anchor system model and the failure load for all three (3) tests must equal or exceed four thousand seven hundred twenty-five (4,725) pounds. The manager must certify that three (3) pullout tests were performed on each anchor system model. The anchor shall be installed with the specified tie attached in a soil type for which the anchor is designed and pulled at an angle between forty degrees (40°) and fifty degrees (50°). The anchor will be approved for all soil test probe values at or above the soil test probe value in which the anchor is tested. The device shall be set up as required by the manufacturer’s installation manual. The test report shall include a photograph or drawing of the anchor demonstrating it is fully set up as required. The load at failure and the type of failure shall be described. The anchoring system must be capable of meeting or exceeding the Zone 1 wind load requirements of the Federal Manufactured Home Construction and Safety Standards 24 CFR section 3280.306; B. Failure and ultimate load capacity tests shall be performed on three (3) samples of each component part and must also be witnessed by the manager; C. Laboratory destruction tests shall be performed on each anchor system model and the failure load must equal or exceed four thousand seven hundred twenty-five (4,725) pounds. These tests are needed to establish the required strengths of the components and component connections of an anchor. 3. The result from each test will indicate— A. Point and mode of failure; B. Force required for failure; C. Description of test procedure; D. Test equipment used. 4. The report of the results of the test in specified soil or rock groups will also include: A. Method of installation; B. Date of installation; C. Date of test; D. Soil profile description and soil test probe values. 5. The anchor manufacturer shall furnish and ship with each anchoring system, information on the types of soil in which the anchor has been tested and certified for installation, instructions on the method of installation, and procedure for identifying soil types. A copy of the manufacturer’s installation manual must be submitted to the manager. The manager shall maintain a copy of the most recent revision of the manufacturer’s installation manual. 6. The manager, upon receipt of new or additional information relating to the performance of any anchoring system, or a similar anchoring system, may request from the manufacturer of that anchoring system, additional testing or supplemental information; (J) The location in this state where the system for which the approval is sought may be inspected by the manager; and (K) An affidavit of the applicant or the applicant’s agent if the applicant is a corporation, that the system for which the approval is sought will be manufactured in accordance with the plans and specifications submitted with the application and that as such it complies with the standards. (3) Within fifteen (15) working days after the receipt of a complete application for an approval the manager shall inspect for compliance with the standards the manufactured home tie-down system for which the approval is sought. An approval or a refusal to grant an approval shall be issued in writing. A notice of a refusal to grant an approval shall specify the reason for the refusal. If through no fault of the applicant such inspection is not conducted within the prescribed time, the approval shall be issued if no basis for refusal is found on the face of the application. (4) No person, without the manager’s authorization, may copy or otherwise duplicate an approval unless the word “copy” appears in at least thirty-six- (36-) point type down the left and right margins of such approval. (5) Any person who purchases a manufactured home tie-down system shall be furnished by the seller with a copy of the approval for the system purchased. (6) The manager shall issue an original approval for each place of business at which an applicant or his/her authorized agent sells, offers for sale, or offers to install an approved manufactured home tie-down system.
