TITLE: FMVSS 210 Compliance - 1995 Cirrus

ATTACHMT: 12/21/95 letter from Kenneth N. Weinstein to Lewis H. Goldfarb

TEXT: As we discussed last week, I am attaching a memorandum setting forth Chrysler's legal position regarding the above compliance review. I am also submitting a summary report of a compliance test performed on December 8, 1995 in accordance with the procedu res specified in FMVSS 210 and the published test protocol.

The test data confirm that the Cirrus satisfied the 3000 load requirement with a 20% margin at NHTSA's slower onset speed of 25 seconds. We believe this demonstrates full compliance with FMVSS 210.

As you know, the non-compliance found by OVSC staff in July was the result of a laboratory test that placed the pelvic body block 4 inches forward from the seat back. Our tests are conducted with the block positioned against the seat back. We advised OV SC staff in September that this alteration in the pelvic body block location significantly altered the stresses imposed on the rear seat anchorages as compared with the stresses imposed when the body block is positioned against the seat back. Since neit her the procedures specified in the standard nor the published laboratory test protocol specify the location of the body block, our compliance test represents a valid demonstration of compliance with the standard and should be accepted by OVSC.

The attached memorandum provides a legal analysis in support of our position. In essence, it shows that NHTSA's interpretation of the standard as requiring that compliance be achieved regardless of the placement of the body block is contrary to the Safet y Act mandate that standards "be stated in objective terms."

I would appreciate an opportunity to discuss this further after your review.

MEMORANDUM

December 13, 1995

TO: Kenneth Weinstein, Esq.

FROM: Lewis Goldfarb, Esq.

RE: FMVSS 210 Compliance

This memorandum summarizes Chrysler's legal analysis in support of its position that the 1995 Cirrus LX vehicles comply with FMVSS 210.

A. The Chrysler Cirrus LX Complies with FMVSS 210.

In July 1995, Chrysler was notified by NHTSA's Office of Vehicle Safety Compliance that a 1995 Chrysler Cirrus LX apparently failed a compliance test measuring conformity with FMVSS 210 S4.2.2. The OVSC staff informed Chrysler personnel that the rear outboard driver-side anchorage bolt weld-nut did not sustain the 3,000 lb. load required by the referenced subsection of FMVSS 210.

After careful analysis by Chrysler, the company has confirmed its position that the 1995 Cirrus LX complies with FMVSS 210 when tested in accordance with the procedures specified in the standard and the published laboratory test protocol. Chrysler ha s also concluded that the NHTSA test result appearing to show noncompliance was attributable to the location of the pelvic body block during the NHTSA test. NHTSA's laboratory acknowledged that it placed the pelvic body block in the Cirrus test approxim ately 4 inches forward from the seat back. As the OVSC staff was advised by letter dated September 28, 1995, Chrysler has determined that this alteration in the pelvic body block location significantly altered the stresses imposed on the rear seat ancho rages, as compared with the stresses imposed when the body block is positioned against the seat back.

Although Chrysler initially believed that the apparent noncompliance was attributable to differences between NHTSA's comparatively slow load application rate (approximately 25 seconds) and Chrysler's faster load application rate (approximately 10 seco nds), Chrysler has now confirmed that the Cirrus meets the requirements of FMVSS 210 S4.2.2, even at the slower NHTSA load application rate, with the pelvic body block positioned against the seat back.

Chrysler has therefore determined that the only remaining issue is whether NHTSA's test can form the basis of a finding of noncompliance. In light of the obvious influence of the location of the pelvic body block -- a variable that is not specified i n the Standard or in the accompanying test procedures -- Chrysler respectfully submits that NHTSA's test does not demonstrate a noncompliance with FMVSS 210, and that NHTSA cannot sustain a finding of noncompliance on the basis of an unspecified test pro cedure.

B. NHTSA Cannot Lawfully Base a Noncompliance Determination on an Unspecified Test Procedure.

NHTSA's statutory authority to promulgate standards is governed by the provisions of Title 49 of the United States Code, Chapter 301 (Motor Vehicle Safety) (formerly the National Traffic and Motor Vehicle Safety Act). Chapter 301 provides that a moto r vehicle safety standard "shall be practicable, meet the need for motor vehicle safety, and be stated in objective terms." 49 U.S.C. @ 30111(a).

These statutory criteria for motor vehicle safety standards have been construed by the Federal courts to require NHTSA to specify objective criteria and test procedures for measuring compliance with each safety standard. In one of the first cases con struing NHTSA's safety standard-setting authority, the Court found as follows:

"The importance of objectivity in safety standards cannot be overemphasized. The Act puts the burden upon the manufacturer to assure that his vehicles comply under pain of substantial penalties. In the absence of objectively defined performance requirem ents and test procedures, a manufacturer has no assurance that his own test results will be duplicated in tests conducted by the Agency. Accordingly, such objective criteria are absolutely necessary so that 'the question of whether there is compliance wi th the standard can be answered by objective measurement and without recourse to any subjective determination.'

Objective, in the context of this case, means that tests to determine compliance must be capable of producing identical results when test conditions are exactly duplicated, that they be decisively demonstrable by performing a rational test procedure, and that compliance is based upon the readings obtained from measuring instruments as opposed to the subjective opinions of human beings."

Chrysler Corporation v. Department of Transportation, 472 F.2d 659, 675-676 (6th Cir. 1972) (two footnotes omitted) (quotation in first paragraph is from the House Report accompanying enactment of the National Traffic and Motor Vehicle Safety Act, H.R. 1 776, 89th Cong. 2d Sess. 1966 at p. 16).

The court went on to conclude that the provisions of FMVSS 208 under review at that time were not objective, because they permitted too much variability in the results of compliance tests conducted in literal compliance with the specified procedures.

Here, NHTSA has specified extensive test procedures for demonstrating compliance with FMVSS 210 within the text of the standard itself (S5. Test Procedures), and has supplemented those regulatory test procedures with a published laboratory test protoc ol, the latest version of which is TP-210-09. Neither the test procedures within the standard nor the accompanying test protocol makes any provision for locating the pelvic body block in the test vehicle for the anchorage loading compliance test. In the absence of a specification, Chrysler has consistently placed the body block against the seat back, which is the most natural and representative location for the body block. As far as Chrysler could ascertain from a review of prior NHTSA compliance tests , the agency has also customarily located the pelvic body block against the seat back during FMVSS 210 compliance tests.

On July 27, 1995, Chrysler representatives met with NHTSA compliance engineer Jeff Giuseppe and representatives of NHTSA's contractor, General Testing Laboratory. At that meeting, the Chrysler representatives were informed that NHTSA's contractor; GT L, moved the pelvic body block several inches forward of the seat back in order to prevent breaking the seat belt buckle during the load application test on the Cirrus.

This relocation of the pelvic body block away from the rear of the seat is not authorized by FMVSS 210 or its published test protocol. The rationale offered for the relocation - that the relocation was necessary to avoid breakage of the seat belt buc kle during the compliance test -- is inconsistent with the 1990 amendments to FMVSS 210 and the implementing instruction in the published test procedure.

In 1990, NHTSA addressed the very issue of the potential for breakage of the buckle or webbing during the anchorage loading test, and decided to resolve the potential breakage problem by authorizing the use of cables, chains or high strength webbing t o impose the load on anchorages during FMVSS 210 compliance testing, as long as the material used to apply the load to the anchorages duplicates the geometry of the original equipment webbing at that seating position at the initiation of the compliance t est. Final Rule amending FMVSS 210, 55 Fed. Reg. 17970 at 17980 (April 30, 1990); Final Rule responding to Petitions for Reconsideration, 56 Fed. Reg. 63676 at 63677 (December 5, 1991). In the 1990 Final Rule, NHTSA emphasized that its decision was inte nded to assure that "compliance testing should not result in unrealistic loading for the anchorages."

In the published test protocol, NHTSA implemented this amendment to FMVSS 210 by directing laboratories to address potential buckle or webbing breakage by replacing seat belt webbing and/or buckles in the area of the body blocks with wire rope. (See Sect ion 12, Compliance Test Execution.) At no time in the rulemaking or in the implementing test protocol has NHTSA ever suggested that the hardware breakage problem could or should be addressed by relocating the pelvic body block to some unspecified locatio n away from the seat back of the test vehicle.

In any event, it does not matter whether the relocation of the body block is helpful to the agency in avoiding compliance test difficulties. The important point is that the contractor's relocation of the pelvic body block has adversely affected the o utcome of the compliance test, by introducing a variable in the compliance test procedure that is not authorized by the NHTSA standard or its implementing published test protocol.

On its face, FMVSS 210 requires demonstration of anchorage strength under certain specified test conditions. Chrysler has demonstrated compliance with those requirements. It is only after NHTSA's contractor relocated the pelvic body block to a locat ion not specified in the standard and not consistent with NHTSA's own prior laboratory test reports, that the laboratory was able to show an apparent noncompliance in the case of the Cirrus.

NHTSA is required to specify objective requirements in its safety standards, and to specify repeatable test procedures by which compliance can be demonstrated. Chrysler Corp. v. Department of Transportation, 472 F.2d at 676. In the Cirrus matter, the NHTSA laboratory's relocation of the pelvic body block was not authorized by the FMVSS 210 test procedure or the published test protocol. Thus, NHTSA is attempting to demonstrate noncompliance on the basis of an unspecified test variable, which it cann ot do consistent with its obligation to specify repeatable test procedures. "Manufacturers are entitled to testing criteria that they can rely upon with certainty." Paccar, Inc. v. National Highway Traffic Safety Administration, 573 F.2d 632, 644 (9th C ir., 1978), cert. den. 439 U.S. 862 (1978).

Furthermore, NHTSA is not free to make changes in its compliance test procedures if those changes can affect the outcome of the compliance test, unless NHTSA provides adequate notice to the regulated industry. Absent such notice, NHTSA cannot retroac tively interpret FMVSS 210 to require compliance with the anchorage strength requirements with a relocated pelvic body block. General Electric Company v. U.S. EPA, 15 F.3d 1324, 1333-1334 (D.C. Cir. 1995) (even if agency interpretation of a standard is r easonable and entitled to deference on a prospective basis, it cannot be enforced retroactively if the standard does not "fairly inform" the regulated industry of the agency's perspective).

C. Conclusion.

NHTSA cannot base a determination of noncompliance with FMVSS 210 on a variable test procedure that is not specified in the Standard. To hold otherwise would sanction a wholesale departure from the fundamental requirement in Chapter 301 for "objectiv e" standards, compliance with which can be measured in accordance with repeatable, producible test procedures. Chrysler has demonstrated the Cirrus' compliance with FMVSS 210 in accordance with the regulatory test procedures and published test protocol. NHTSA's compliance investigation should be closed.
