## NHTSA's summary

Altec has learned that a connection in the upper controls joystick on certain LS49 aerial devices built from August 2023 to July 2024 can fail due to water intrusion rendering the controller inoperable from the platform. If this failure happens with the boom elevated, the operator in the platform will need another person to use the lower controls to lower the platform. The manufacturer has redesigned the connection and is providing a replacement joystick to eliminate this issue.
