What's wrong?
The boom valve on the 2020 Altec Aerial Device controls hydraulic flow for the aerial boom. In normal operation, the valve sends oil through the intended passages so the boom responds predictably to operator controls. A plug belongs in this valve position to close off a passage that should not be active.
On affected AN67-E100 articulating non-overcenter aerial devices, the supplier installed a shuttle cartridge where that plug should be. A shuttle cartridge is a movable valve insert, not a solid closure. With that cartridge in place, the valve is built differently from the intended design, so Altec replaces the shuttle cartridge with the correct plug.
The issue can be found during the preoperational inspection. Before use, the inspection should identify that the boom valve has the wrong cartridge installed instead of the required plug.
