Dear Ms. Flint:

This responds to your letter asking whether this agency must approve your product, an epoxy putty that could be used to repair leaking gas tanks. You said a customer would like to market your product "for fleet (buses and truck) maintenance." The answer is no, the National Highway Traffic Safety Administration (NHTSA) does not approve or certify products.

By way of background, NHTSA is authorized to issue Federal Motor Vehicle Safety Standards (FMVSS's) applying to the manufacture of new motor vehicles and items of motor vehicle equipment. NHTSA is not authorized to certify or approve motor vehicles or motor vehicle equipment for compliance with our FMVSS's. Instead, under the National Traffic and Motor Vehicle Safety Act (copy enclosed), each manufacturer of a motor vehicle or item of motor vehicle equipment is responsible for certifying that its products meet all of our applicable safety standards. This process requires each manufacturer to determine in the exercise of due care that its products meet all applicable requirements. NHTSA regularly tests vehicles and equipment for compliance with the FMVSS's as part of its enforcement program. In addition, the agency also investigates safety-related defects in motor vehicles and items of motor vehicle equipment.

There isn't any FMVSS that directly applies to repair putty for fuel tanks. Federal Motor Vehicle Safety Standard 301, Fuel System Integrity, sets performance requirements for new vehicles with a gross vehicle weight rating of 10,000 pounds or less and school buses. The standard does not apply to products sold to repair fuel tanks on vehicles already in use.

Repair of a damaged fuel tank in a new vehicle would be affected by the statutory requirement that the vehicle, when first sold to a consumer, must comply with FMVSS 301. If a new vehicle's fuel tank is repaired prior to such sale, the person making the repairs would be considered a vehicle alterer under our regulation on certification (Part 567, copy enclosed). As an alterer, the person must certify that the fuel system, as altered, continues to comply with all of the applicable requirements of Standard 301.

After a vehicle is first sold to a consumer, repairs to a vehicle are potentially affected by section 108(a)(2)(A) of the Vehicle Safety Act. That section prohibits manufacturers, distributors, dealers, or motor vehicle repair businesses from knowingly rendering inoperative any device or element of design installed in compliance with a FMVSS. However, the agency does not view that prohibition as applying to the repair of a fuel tank which has been previously installed in a vehicle and damaged in use. The agency considers the event that damaged the fuel tank and not any subsequent action by a person repairing the damaged tank in a used vehicle as the event that "rendered inoperative" the compliance of the fuel tank with the standard. Thus, a person in one of the aforementioned categories may use the putty to repair a damaged fuel tank on a used vehicle without regard to the render inoperative prohibition. Of course, however, NHTSA urges all persons repairing motor vehicles to ensure that the repair is done safely.

The prohibition of section 108(a)(2)(A) does not apply to individual vehicle owners who alter their own vehicles. Thus, under our requirements, individual owners may use the repair putty regardless of its effect on the performance of fuel tanks. However, NHTSA encourages vehicle owners not to tamper with vehicle safety equipment if the modification would degrade the safety of the vehicle.

An issue raised by your inquiry is whether the putty is "motor vehicle equipment" under the Vehicle Safety Act. Manufacturers of motor vehicle equipment are subject to the requirements in sections 151-159 of the Safety Act concerning the recall and remedy of products with defects relating to motor vehicle safety. As discussed below, we believe the putty is not motor vehicle equipment.

Section 103(4) of the Act defines, in relevant part, the term "motor vehicle equipment" as:

any system, part, or component of a motor vehicle as originally manufactured or any similar part or component manufactured or sold for replacement or improvement of such system, part, or component or as any accessory, or addition to the motor vehicle . . . (emphasis added).

In determining whether an item of equipment is considered an "accessory . . . to the motor vehicle," NHTSA applies not only the relevant statutory language, but also two criteria. The first criterion is whether a substantial portion of the expected uses of the item are related to the operation or maintenance of motor vehicles. We determine the expected uses by considering product advertising, product labeling, and the type of store that retails the product, as well as available information about the actual use of the product. The second criterion is whether the product is intended to be used principally by ordinary users of motor vehicles (e.g., items normally used by professional vehicle repair and maintenance personnel would not qualify). If the product satifies both criteria, the product is considered to be an "accessory" and thus is subject to the provisions of the Safety Act.

Applying these criteria to your inquiry, the first criterion appears to be satisfied because a substantial portion of the expected uses of the putty is related to the operation or maintenance of motor vehicles. The second criterion, however, does not appear to be satisfied. In a December 21, 1990 telephone conversation with Ms. Fujita of my staff, you stated that the putty would be sold to professional mechanics only. Since your product is not intended for use by ordinary vehicle users, the putty is not considered to be motor vehicle equipment.

Our sister agency in the Department, the Federal Highway Administration (FHWA), has operational and equipment requirements for commercial vehicles used in interstate commerce. We will forward a copy of your letter to the FHWA for information about those requirements.

I hope this information is helpful.

Sincerely,

Paul Jackson Rice Chief Counsel
