Aerial Turntable Failures
NHTSA Preliminary Evaluation PE19016 - closed, opened 2019-11-12.
NHTSA investigation PE19016 is a Preliminary Evaluation opened on 2019-11-12 and currently closed. The subject is tracked inside the Office of Defects Investigation queue. Latest activity on this investigation was logged on 2020-03-05 - NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.
A Preliminary Evaluation like PE19016 is the entry point of the federal defect-investigation process. NHTSA engineers scan complaint databases, field reports, and manufacturer data to decide whether an Engineering Analysis is warranted, whether a voluntary recall is already sufficient, or whether the pattern does not rise to a defect finding.
Investigators summarized the matter as follows: "The Office of Defects Investigation (ODI) opened this PE on November 12th, 2019 after receiving 2 consumer complaints alleging the aerial turntable on their 2013 KME fire trucks were supplied from the manufacturer withou..." 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
The Office of Defects Investigation (ODI) opened this PE on November 12th, 2019 after receiving 2 consumer complaints alleging the aerial turntable on their 2013 KME fire trucks were supplied from the manufacturer without lubrication. When inspected, it was found that some of the turntable internal gears had seized and other gearbox internals were severely corroded and pitted due to lack of lubrication. ODI interviewed the two complainants and received documentation showing failed gearing and drive-planetaries due to a lack of lubrication. In addition, ODI visited the manufacturer's assembly plant to learn about the drive system and how it is received from the supplier Kraft Hydraulics. ODI learned the electric motor and apparatus are shipped dry. The system is then painted by KME prior to assembly on the fire truck when lubrication is then supposed to occur. KME has acknowledged the missed production step of filling the turntables with lubricating oil after installation on the vehicle. The turntable gearbox is supposed to contain lubricating oil to reduce friction and protect internal gears from corrosion. If the turntable was not filled with lubricating oil, it may seize or freely traverse without control, possibly striking objects and potentially endangering fire fighter safety. As part of the safety recall, KME will inspect and verify if the turntables contain lubricating oil. If not, they will be sent to the manufacturer for rebuild. If the owner has already incurred costs to remedy this issue, they will be directed in the notification letter to contact KME for reimbursement. This Preliminary Evaluation has been closed with a voluntary safety recall released by the manufacturer (20V-006).

About This Investigation Type
A Preliminary Evaluation (PE) is the first phase of NHTSA's investigation process. It is opened when the agency identifies a potential safety defect pattern, usually triggered by consumer complaints, manufacturer reports, or field monitoring. During a PE, NHTSA gathers information to determine whether a formal engineering analysis is warranted.
