TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of March 3, 1973, in which you ask two questions regarding your company's practice of maintaining records on replacement parts for vehicles you manufacture. You appear to be under the impression that the retention of such records is necessary for purposes of certification to the Federal motor vehicle safety standards.

There are no requirements for the certification or replacement vehicle parts, unless the parts themselves are subject to a safety standard. At present, Standards Nos. 106, 108, 109, 116, 117, 205, 211, and 213 apply to items of motor vehicle equipment, and it is only with respect to replacement equipment subject to these standards that certification is required under Section 114 of the National Traffic and Motor Vehicle Safety Act.

Moreover, the NHTSA does not have specific requirements that manufacturers maintain records as to those equipment items that must be certified. Of course, good manufacturing practice would dictate that manufacturers maintain sufficient records to show that "due care" was exercised in manufacturing the items to conform to the standards. This is the legal standard applicable to manufacturers under the Safety Act. But it is for each manufacturer to determine for himself the extent to which such records should be maintained.

It is possible that any replacement equipment item, whether or not subject to a standard, may be found to contain a safety-related defect. The discovery of a defect by either the

manufacturer or the NHTSA will result in the manufacturer notifying purchasers of whom he has knowledge. (Section 113 of the Safety Act, 15 USC 1402) Here again, good manufacturing practice would require a manufacturer to maintain sufficient records that if a defect is found, the manufacturer will be able to determine the extent of his production in which the defect may exist. A manufacturer who has such records will be able thereby to minimize his burden of notification. However, as in the case of certification, the NHTSA does not have requirements for record retention that manufacturers must follow. It is for the manufacturer to determine the extent to which he should maintain records for these purposes.
