Air Crash Investigation - Frozen in Flight / Deep Freeze (S07E08)

American Eagle Flight 4184, was an American Eagle ATR 72 that crashed after flying into unknown icing conditions on October 31, 1994. Control was lost and all aboard were killed.

The flight was en route from Indianapolis International Airport, Indiana to O'Hare International Airport, Chicago, Illinois. Bad weather in Chicago caused delays, prompting air traffic control to hold Flight 4184 over the nearby LUCIT intersection at 10,000 ft (3,000 m)

While holding, the plane encountered freezing rain — a dangerous icing condition where supercooled droplets rapidly cause intense ice buildup. Soon after, they were cleared to descend to 8,000 ft (2,400 m). After this descent the pilots were ordered to make another hold. While in the holding pattern, a warning sound indicating an overspeed warning due to the extended flaps was heard in the cockpit. After the pilot took action by retracting the flaps, a strange noise was heard on the cockpit voice recorder, followed by an uncommanded roll excursion which disengaged the autopilot. Flight recorder data showed that the ATR subsequently went through at least one full roll with the crew able to regain control of the rapidly descending aircraft. However, another roll occurred shortly thereafter. Fewer than thirty seconds later, contact was lost as the plane crashed into a soybean field near Roselawn, Indiana (coordinates: 41.0944; -87.3222), killing all 64 passengers and 4 crew on board. The disintegration of the plane indicated an extreme velocity, and data recovered from the flight data recorder verified that the plane was traveling 375 knots (695 km/h) indicated airspeed at impact.

Flight 4184 was the first loss of an ATR 72 aircraft, it was also the highest death toll of any aviation accident involving an ATR 72 anywhere in the world. Robert A. Clifford, a Chicago airplane accident attorney, represented 16 of the victims. As the trial was ready to begin, the defendants agreed to a record $110 million settlement and an apology in open court.

at 01:00 scariest face ever!

@toontown779 haha lol

It seems to me that Greg Feith investigated almost every plane crash in America. On every ACI episode involving a plane crash in USA he's the lead investigator.

The picture after 59 seconds scares the shit into me

When I fly, I always turn on anti-ice if I fly through cloubs and storms.

poor kid

[legmanpv72]

how anyone dislike this

[macrent2]

@normanjtongmd It is still "Under Investigation" and has had three reports in the past 2 years and 7 months. Air speed, lightning, pitch and stall? We will probably never know.

@Sheron124 LMAO

@BRUCEBAUM45 Greg Feith is the man!!

[trSoapman]

@BRUCEBAUM45 It seems that he is for the NTSB, what Gibbs is for the NCIS ;)

Lessons learned! Train all flight crew about professionalism and focus on work at hand! Passengers' lives are at risk!

Did super-cooled water droplet ice formation on wings contribute to the crash of Air France Flight 447?
