Service bulletin SIL 856
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 learned of the potential for washers on the outer race rotation bearing cap screws to overlap the adjacent weld on AT238P and AT335 aerial devices built from October 2019 to November 2021. While there have been no reports of unit failures to date, interference with the weld under the washer could cause cap screw failure.
