NHTSA Engineering Analysis EA02034 - closed, opened 2002-12-03 and involving the INTERNATIONAL INTERNATIONAL.
NHTSA investigation EA02034 is a Engineering Analysis opened on 2002-12-03 and currently closed. The subject of record is INTERNATIONAL INTERNATIONAL, which places this file inside the Office of Defects Investigation queue for INTERNATIONAL. Latest activity on this investigation was logged on 2004-02-10 - NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.
An Engineering Analysis like EA02034 is the deeper technical phase that follows a PE. NHTSA requests design, warranty, and field-failure data from the manufacturer, conducts its own testing when needed, and determines whether the evidence supports a safety defect finding that would compel a recall.
Investigators summarized the matter as follows: "THIS INVESTIGATION FOCUSED ON INTERNATIONAL MEDIUM DUTY TRUCKS AND SCHOOL BUS CHASSIS WEIGHING UP TO 33,000 POUNDS, EQUIPPED WITH HYDRAULIC BRAKES AND BUILT WITH THE BOSCH ZERO OFFSET PIN SLIDE (ZOPS) BRAKE SYSTEM CALIPE..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time. Related INTERNATIONAL files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.
Investigation Summary
THIS INVESTIGATION FOCUSED ON INTERNATIONAL MEDIUM DUTY TRUCKS AND SCHOOL BUS CHASSIS WEIGHING UP TO 33,000 POUNDS, EQUIPPED WITH HYDRAULIC BRAKES AND BUILT WITH THE BOSCH ZERO OFFSET PIN SLIDE (ZOPS) BRAKE SYSTEM CALIPERS. INTERNATIONAL USED THE ZOPS CALIPERS FROM APRIL 1997 THROUGH JUNE 2002. ODI WAS CONCERNED ABOUT REPORTS OF THE BRAKE CALIPERS STICKING IN THE APPLIED POSITION, RESULTING IN EXCESSIVE HEAT. AS THE INVESTIGATION PROGRESSED, ODI BECAME AWARE OF WHEEL END FIRES, SOME OF WHICH OCCURRED ON SCHOOL BUSES. DURING THE INVESTIGATION ODI OBTAINED WARRANTY DATA WHICH WAS SORTED AND ANALYZED BY VRTC TEST ENGINEERS AND ODI TO GAIN AN UNDERSTANDING OF THE MAGNITUDE OF THE PROBLEM. AFTER A THOROUGH WARRANTY DATA ANALYSIS, RELATED TESTING AND DOCUMENT REVIEWS, ODI MET WITH INTERNATIONAL, SHARED THE DATA ANALYSIS AND SHORTLY AFTERWARDS, INTERNATIONAL AGREED TO A SAFETY RECALL. FURTHER DETAILS ARE INCLUDED ON PAGES 2 - 4.
About This Investigation Type
An Engineering Analysis (EA) is the in-depth phase following a Preliminary Evaluation. NHTSA engineers conduct testing, collect data from manufacturers, and perform detailed technical analysis to determine whether a safety defect exists. An EA may lead to a voluntary recall by the manufacturer or, in rare cases, a mandatory recall order.
