Service bulletin SIL-3220
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 that the feeder tube on the lower boom lift cylinder of certain AT40-G aerial devices built from May 2023 through September 2024 could contact the leveling cylinder weld boss. The cylinder counterbalance valves are not affected and there have been no reports of unintentional boom movement.
