ACTION: Notice of initial decision and public meeting. ----------------------------------------------------------------------- SUMMARY: NHTSA will hold a public meeting beginning at 10:00 a.m. on December 6, 1994 regarding the initial decision by the Secretary of Transportation that certain pickup trucks and other vehicles manufactured by General Motors Corporation (GM) contain a defect that relates to motor vehicle safety. FOR FURTHER INFORMATION CONTACT: Ellen Berlin, Director, Office of Public and Consumer Affairs, National Highway Traffic Safety Administration, 400 Seventh Street, SW, Washington, DC 20590; (202) 366-9550. SUPPLEMENTARY INFORMATION: Pursuant to 49 U.S.C. 30118(a) (formerly section 152(a) of the National Traffic and Motor Vehicle Safety Act of 1966, as amended, 15 U.S.C. 1412(a)), Secretary of Transportation Federico Pena has made an initial decision that model year 1973-1991 full-sized GM pickup trucks and cab-chassis equipped with fuel tanks mounted outboard of the frame rails contain a defect that relates to motor vehicle safety. The rationale for this initial decision is set forth in the Engineering Analysis (EA) Report for EA92-041. The entire report, as well as the complete record on which the initial decision is based, are available for inspection during working hours (9:30 a.m. to 4:00 p.m.) in NHTSA's Technical Reference Library, Room 5108, 400 Seventh Street, SW, Washington, DC 20590. That record consists of the public files for EA92-041 and Defect Petition (DP) 92-016. The Executive Summary of the EA Report is set out below. Engineering Analysis Report--Executive Summary This Engineering Analysis was opened on December 8, 1992, as a result of granting a petition from the Center for Auto Safety (CAS) and Public Citizen to ``initiate a defect investigation into and recall all Chevrolet/GMC full-sized pickups (C/K-series) with fuel tank(s) * * * mounted outboard of frame rails.'' The objective of the investigation was to determine whether certain model year 1970-1991 Chevrolet and GMC full-sized pickup trucks contain a defect that poses an unreasonable risk to safety, related to the danger of fires following crashes, with primary focus on side-impact crashes. In the investigation, the National Highway Traffic Safety Administration's (NHTSA) Office of Defects Investigation (ODI) conducted analyses of real-world accident data and performed laboratory crash tests of the subject and peer vehicles. ODI also addressed questions related to the compliance of these trucks with Federal Motor Vehicle Safety Standard (FMVSS) No. 301, ``Fuel System Integrity.'' Additionally, ODI examined whether the fuel tanks and related components on the trucks were unduly affected by corrosion that could make them more likely to be involved in a fire. On April 9, 1993, ODI sent a recall request letter to General Motors Corporation (GM), recommending that GM conduct a safety recall on GM trucks with fuel tanks mounted outside the frame rails (subject vehicles). That letter was based on two principal factors: 1. Real-world accident data in the Fatal Accident Reporting System (FARS) indicate that there is an increased risk of fatality caused by fire in side-impact crashes involving the subject vehicles compared to 1973-1987 Ford full-sized pickup trucks. That increased risk led to an estimate that, in 1993, an additional 5-6 fatalities would occur in side-impact crashes involving the subject vehicles compared to what would occur if those trucks had the same side-impact fire performance as full-sized Ford pickups. 2. Laboratory crash tests corroborated the findings from the real- world accident data analysis. That is, in certain comparable side- impact crash tests, GM fuel tanks leaked and Ford tanks did not. Further, these tests used instrumented test dummies. Dummy measurements indicate that humans could have survived the crash forces at the impact speeds at which the subject vehicles leaked. While these speeds are well in excess of the impact speed specified in FMVSS No. 301, the results indicate the increased fire risk in the GM trucks in crashes that are otherwise survivable. GM provided an extensive amount of data and arguments in response to the recall request letter. ODI has completed an exhaustive review and analysis of the GM submissions and has conducted a variety of additional analyses associated with issues involved in this investigation. These include:An assessment of the effect of corrosion on fuel tank leakage and fire performance in the subject vehicles; An analysis of non-fatal burn injuries in side-impact crashes involving the subject vehicles; An in-depth review of all available police accident reports and other records of side-impact, fire-involved fatal crashes involving the subject vehicles to assess the crash conditions and severity of each; An update of the FARS analysis that led to the April 9, 1993 recall request letter; An analysis of the reasonableness of GM's decision to design the subject vehicle with side-mounted fuel-tanks, given what GM knew about the safety risks associated with that design and the availability of feasible alternative designs; and An analysis of the information about the risk of post- crash fuel leaks that became available to GM during the time the subject vehicles were being manufactured. Principal Findings A review of GM submissions, as well as ODI testing, indicates that there are no data on which to conclude that the GM trucks to which FMVSS No. 301 applied, when new, did not comply with the standard. There are no data to indicate a relationship between fuel tank corrosion and increased fire risk in the subject vehicles, either in side impacts or in non-crash incidents. Apart from the basic decision to locate the fuel tanks of the subject vehicles outside of the frame rails, many of the specific features of the design of the fuel storage system and the surrounding area have increased the likelihood of post-crash fuel fires in the subject vehicles. Based on a review of 1979-1993 accident data reflecting the performance of full-sized pickups in side-impact fatal crashes involving fire, occupants of the subject vehicles experienced 2.8 times as many fire-related fatalities (i.e., fatalities in crashes in which a fire occurred) per million registered vehicle-years as occupants of Ford pickups and 2.5 times as many as occupants of Dodge pickups. Where the FARS code indicated that the most harmful event (MHE) of the crash was fire, the GM-to-Ford occupant fatality per million registered vehicle-years ratio is 3.4 to 1, and the GM-to-Dodge ratio is 6.1 to 1. Real-world accidents data do not support GM's contention that GM and Ford pickup trucks have comparable side-impact fire performance and that differences in driver demographics and driver behavior explain the difference in the rates of fire-related and MHE- fire fatalities in side-impact crashes for the GM and Ford pickups. This is demonstrated by the tremendous reduction in the rate of MHE- fire side-impact fatalities that occurred after GM moved the fuel tanks for these pickups inside the frame rails in model year 1988. Contrary to GM's contentions, the MHE coding in FARS is a reliable indicator of the number of fatalities actually caused by fire. FARS data indicate that, if past trends continue, there would be approximately five additional fatalities due to fire in side- impact crashes in 1994 compared to what would occur if the subject vehicles had the same side-impact fire performance as Ford full-sized pickups. Reports of non-fatal burn injuries indicate that, if past trends continue, there would be three to four additional non-fatal burn injuries in 1994 in side-impact crashes involving the subject vehicles compared to the Ford pickups. Laboratory crash data indicate that, at certain impact speeds and configurations, the subject vehicles will leak fuel in side impacts, while comparable Ford pickups will not. While the crash severities in fatal side-impact, fire- involved crashes involving the subject vehicles are far in excess of the severity specified in FMVSS No. 301, they are generally less than the severities that result in fires in fatal side-impact crashes involving the Ford pickups. GM was aware at the time it designed the subject vehicles in the early 1970s that side-mounted fuel tank design presented an increased risk of post-crash fuel fed fires in side impacts, compared to the risk associated with other feasible alternative designs. Moreover, GM obtained additional information demonstrating the increased risk associated with the side-mounted tanks during the 15- year period the subject vehicles were in production. Principal Conclusions The increased risk of death and injury from fire in side- impact crashes involving the subject vehicles is a result of the design of their fuel storage system, primarily the location of the fuel tanks outside of the frame rails, supplemented by other features of the design. Given the state of the art at the time and GM's awareness of the likely consequences, it was unreasonable for GM to design the subject vehicles with fuel tanks outside the frame rails. The increased safety risk due to post-crash fires in the subject vehicles is unreasonable. Therefore, on the basis of the entire investigative record, I have initially decided, pursuant to 49 U.S.C. 30118(a) (formerly section 152(a) of the National Traffic and Motor Vehicle Safety Act), that the subject vehicles contain a defect that relates to motor vehicle safety. [End of Executive Summary] Pursuant to 49 CFR 554.10, a public meeting will be held beginning at 10:00 a.m., on Tuesday, December 6, 1994 in Room 2230, Department of Transportation Building, 400 Seventh Street, SW, Washington, DC, at which time GM and all other interested persons will be afforded an opportunity to present information, views, and arguments on the issue of whether the vehicles covered by this initial decision contain a safety-related defect. NHTSA's Deputy Administrator, Christopher A. Hart, will preside at that public meeting. Interested persons are invited to participate in this proceeding through written and/or oral presentations. Persons wishing to make oral presentations are requested to notify Ms. Judy Taylor, Office of Defects Investigation, National Highway Traffic Safety Administration, Room 5326, 400 Seventh Street, SW, Washington, DC 20590 (202) 366-2850, before the close of business on November 28, 1994. Such persons should indicate the approximate amount of time their presentation is expected to take and whether they will need any audio-visual equipment.
