Oaks Amusement Park in Portland will resume operation of the ride that got stuck leaving passengers upside down for 20 minutes.
The manufacturer of the AtmosFear ride inspected it, including software, hardware and the structure. No mechanical, technical or maintenance issues were found.
Software data shows the operator wasn't at fault.
A state-qualified independent inspector also examined the ride, clearing it for operation. They won't run it in 360-degree mode, only 180- or 260-degrees.
