"Dear Mr. Duerr: This is in response to your letter requestin Department of Transportation 'approval' of a fitting to be used in air brake systems in conjunction with your company's product, a driveline brake retarder. I apologize for the delay in this response. Your letter explained that your company's brake retarder is designed to be attached to the air brake system on trucks or buses by means of a fitting, and enclosed a sample of the fitting you plan to use. You asked for DOT approval of the fitting. As explained below, whether the fitting and associated air hoses are subject to the Federal Motor Vehicle Safety Standards (FMVSS) depends upon how the fittings are attached to the vehicle's air brake system. This agency has the authority under the National Traffic and Motor Vehicle Safety Act of 1966 to issue safety standards applicable to new motor vehicles and items of motor vehicle equipment. We have exercised this authority to establish Standard No. 106, Brake Hoses (49 CFR 571.106, copy enclosed), which applies to motor vehicle brake hoses, brake hose assemblies, and brake hose end fittings. Your letter did not provide sufficient information for us to offer an opinion as to whether or not the air lines and end fittings used with your product would be considered 'brake hoses' and 'brake hose end fittings' subject to the requirements of Standard No. 106. It has been NHTSA's long-standing position that accessory air lines and end fittings, such as those used in your product, are 'brake hoses' and 'brake hose end fittings' only if a failure of the line or fitting would result in a loss of pressure in the vehicle's brake system. (See the enclosed June 5, 1987 letter to Albert Schwarz, and the August 3, 1984 letter to Terry Teeter). Accordingly, if a failure of the accessory lines or fittings used with your product could result in a loss of pressure in the brake system, the hoses and fittings are subject to all the provisions of Standard No. 106. In this case, the Safety Act specifies that no person shall 'manufacture for sale, sell, offer for sale, or introduce or deliver for introduction in interstate commerce, or import into the United States' any of those hoses or end fittings unless those hoses and end fittings comply with all of the applicable requirements in Standard No. 106. NHTSA has no authority to certify, endorse, or approve in advance any motor vehicles or motor vehicle equipment, including the hoses and end fittings used for this product. Instead, under the Safety Act, the manufacturer is responsible for certifying that its products meet all applicable safety standards. The manufacturer's certification need not be based on actual tests, the only requirement is that the manufacturer exercise due care when making the certification. Once your company has determined that these hoses and end fittings comply with the requirements of Standard No. 106, the Standard requires you to mark these products with the symbol 'DOT' to show your company's certification of compliance. This agency enforces the requirements of Standard No. 106 by randomly purchasing brake hoses and end fittings that have been certified as complying with Standard No. 106. The certified products are then tested by the agency according to the procedures specified in the standard. If the products pass these tests, no further actions are taken. On the other hand, if the accessory air line running to your product is isolated from the air brake system by means such as a check valve, the hoses and fittings used with your product are not subject to the requirements of Standard No. 106. In this case, your company would not be required to certify that the hoses and fittings used with your product comply with the applicable requirements of Standard No. 106. You would, however, be considered a 'manufacturer' of motor vehicle equipment for the purposes of the Safety Act and our regulations. The Safety Act specifies that if either your company or this agency determines that a safety-related defect exists in your product, your company as the manufacturer must notify purchasers of the safety-related defect and must either: (1) repair the parts so that the defect is removed, or (2) replace the parts with identical or reasonably equivalent parts which do not have a defect. Whichever of these options is chosen, the manufacturer must bear the full expense and cannot charge the owner for the remedy if the equipment was purchased less than 8 years before the notification campaign. Similarly, if this product were subject to Standard No. 106, your company would be required to notify owners and remedy without charge to those owners any noncompliance of your product with the requirements of Standard No. 106, as well as remedying any safety-related defect. For your information, I have enclosed a copy of an information sheet for new manufacturers of motor vehicles and new motor vehicle equipment. This sheet gives a brief description of our regulations and explains how to obtain copies of those regulations. I hope this information is helpful. Please feel free to contact this office if you have any further questions or need additional information. Sincerely, Stephen P. Wood Acting Chief Counsel Enclosures";
