## NHTSA's summary

Altec has learned that on certain AT37\-G aerial devices built from November 2007 to April 2018, the rear torsion bar swing arm can interfere with the long runner channels under the body as the torsion bar rotates during road travel. The interference can cause wear issues and can cause welds on the body mounting angles or cross members to develop cracks.
