American Eagle Flight 4184 was enroute from Indianapolis to O’Hare International Airport. The flight was delayed for landing due to bad weather in Chicago, causing the airplane to be on hold.
While holding, the plane encountered freezing rain. Soon after, they were cleared to descend to 8,000 feet. After descending, the pilots were once again put on hold. While in the holding pattern, a warning sound indicating an overspeed warning due to the extended flaps was heard in the cockpit. The pilot took action by retracting the flaps. When this happened, the cockpit voice recorder picked up a strange noise, followed by an uncommanded roll that caused the autopilot to disengage.
