Service bulletin SIL 831

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Altec has discovered that certain AT200A aerial devices built from June 2020 to January 2021 could have square inside corners on a mounting frame side plate. The square corners can cause excessive stress levels in the side plate. Over time this could cause cracking of the side plate. Altec has redesigned the mounting frame side plate to have rounded corners, and has developed an update process using a template to add a radius to the corners on units in the field. Altec requires the mounting frame to be inspected on each unit no later than the next preventive maintenance interval or 90 days from the receipt of this SIL, whichever comes first. If the inspection confirms the mounting frame side plate has square corners, order the Mounting Frame Update Template Kit. Use the kit to update the mounting frame upon receipt. This inspection and repair are covered under the Altec Warranty Policy and can be performed by Altec, the customer, or the customer's warranty provider.
