Chronology :

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.

October 2023, an updated wire harness, incorporating a crimped / sealed connection, is introduced into production.

November 2023, Pierce receives a report from a customer that during that during a training exercise, with the platform basket approximately one foot off the ground, as the platform operator commanded the aerial to raise, and as the platform basket leveled itself, the front of the platform basket contacted the ground. 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.
