NHTSA's summary

As NHTSA's Office of Defects Investigation wrote it for Preliminary Evaluation PE13-017.

On May 22, 2012 the Office of Defects Investigations (ODI) opened this Preliminary Evaluation (PE) to investigate an alleged failure of an aerial ladder bucket on a subject vehicle while in operation.

The failure occurred during a public relations event at a fire station while four civilians and one firefighter were being elevated in the aerial ladder bucket.

Once the ladder was fully extended at a 45 degree angle, the ladder component of the vehicle experienced a sudden and catastrophic failure. This resulted in the ladder retracting rapidly into its bedded position.

This sudden stoppage caused multiple injuries to all five of the occupants within the aerial ladder bucket.

Sutphen concluded that the main cables were worn. The bearings in the sheaves used in the extend/retract the system had seized and prevented the sheaves from rotating. The cables sliding over the non-moving sheaves resulted in excessive wear and reduced load carrying capacity.

Failure of the extend/retract system can result in either the aerial becoming inoperable or cause it to unexpectedly retract. This movement could result in damage to the vehicle and/or injuries to personnel on or around the vehicle.

Sutphen is conducting a voluntary Safety Recall (13V-565) to address the safety concerns with the aerial ladder.

As part of the remedy, Sutphen will inspect each vehicle for worn parts and will provide detailed instructions for vehicle owners on how to inspect and maintain the aerial ladder portion of the fire apparatus.

What an NHTSA investigation is

NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.

An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
