NHTSA Engineering Analysis EA09008 - closed, opened 2009-05-29.
NHTSA investigation EA09008 is a Engineering Analysis opened on 2009-05-29 and currently closed. The subject is tracked inside the Office of Defects Investigation queue. Latest activity on this investigation was logged on 2010-08-27 - 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 EA09008 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: "PACCAR is conducting an Owner Notification Program (ONP) for select vehicles within the subject and peer populations. The ONP are attached to the closing report and can be found in the NHTSA Technical Service Bulletin (T..." 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.
Investigation Summary
PACCAR is conducting an Owner Notification Program (ONP) for select vehicles within the subject and peer populations. The ONP are attached to the closing report and can be found in the NHTSA Technical Service Bulletin (TSB) database. (TSB: 10033585, 10033584) See Closing report for investigation details.
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.
