No injuries were reported. Pierce personnel visits the subject truck and performs visual / functional inspections. During this inspection, the condition as described could not be duplicated but moisture intrusion / corrosion is observed in the connector on the aerial turntable wiring harness. November 2023, Pierce makes the determination that a safety defect exists in the electrical cable connector. Pierce is not aware of any injuries to persons related to the above referenced condition.
Description of Remedy :
Description of Remedy Program : Pierce will supply, at no charge to the customer, a replacement aerial
turntable wiring harness which utilizes an electrical connection that is permanently crimped together and sealed. An appropriate labor allowance to install the remedy component will be provided. How Remedy Component Differs from Recalled Component : Identify How/When Recall Condition was Corrected in Production : The remedy component will consist of an electrical connection that is no longer a “plug”, but instead is permanently crimped together and sealed – thus preventing influence from and sensitivity to external factors such as strain relief and moisture. Vehicles outside the recall population use an electrical connection that do not use a plug style connection.

Descriptive Information : The vehicles affected by this recall include 100’ mid-mount tower trucks of the models described within this report that are equipped with an aerial platform basket.
Production Dates : MAY 07, 2019 – OCT 31, 2023
VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect :
Description of the Defect : During assembly of the aerial portion to the truck, Pierce connects the male and female ends of an electrical connector on the aerial turntable wiring harness and installs tie straps to reduce the potential for strain and unintended movement of the harness. If the tie straps are not correctly installed, this condition may lead to strain on the electrical connector which could allow for movement of the electrical connector. Movement of the connector could permit a gap to develop at the connection point. Should a gap develop, and moisture enters at the connection point, over time the pins inside the connector could corrode and potentially disrupt the electrical signal which controls the platform basket leveling feature. The signal to adjust the raise, lower, and rotate commands of the aerial device movement, and the emergency shut off button, are not affected by this issue.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : If the electrical signal for the platform basket leveling feature is disrupted, it
may not send a consistent, or any, signal which could lead to the platform Part 573 Safety Recall Report 23V-823 Page 2 basket rotating past the horizontal (level) position. Should this occur, the risk of injury to platform basket occupants is increased if the emergency stop button is not depressed and the required safety restraints are not being worn.
Description of the Cause : NR Identification of Any Warning
that can Occur : There is no known warning to occupants in the platform basket should this condition exist. If the condition occurs, occupants of the platform basket can push the emergency stop button to cease all platform movement. Involved Components : Component Name 1 : Connector

August 2022 a customer contacts Pierce and advises that the platform basket on an aerial device, which was near to the ground, went through its leveling operation and the platform basket made contact with the ground. Pierce personnel visit the subject truck and performs visual / functional checks. Corrosion is discovered in the connector in the aerial turntable wiring harness. The corroded pins are replaced and shrink tubing applied to prevent corrosion from redeveloping. January 2023, a customer contacts Pierce and informs that occupants in the platform basket of an aerial truck experienced platform leveling which was not consistent with normal operation. No contact with the ground was reported and operator error could not be ruled out. Pierce visits the subject truck and performs visual / functional checks. The condition described could not be duplicated. During this inspection corrosion was observed in the connector on the aerial turntable wiring harness. The connector was re-pinned and sealed with heat shrink tubing.
