January 1997 plane crash in Michigan, US

Comair Flight 3272 was a Comair flight from Cincinnati to Detroit on Thursday, January 9, 1997. While on approach for landing, the Embraer EMB 120 Brasilia aircraft crashed nose down 18 mile (29 km) southwest of Detroit Metropolitan Wayne County Airport at 15:54 EST. All 29 aboard, 26 passengers and three crew members, were killed. The cause of the crash was determined to be inadequate and out of date flight crew procedures for icing conditions. Some of these originated with the Federal Aviation Administration's failure to specify suitable minimum airspeeds for icing conditions, while some were Comair procedure manual defects, including superseded instructions on the use of de icing boots that did not follow the aircraft manufacturer's instructions.

There were 26 passengers on board the Embraer 120, registered as N265CA. There were two crew members in the cockpit and a flight attendant in the cabin. The captain was Dann Carlsen, age 42, who was the pilot monitoring (PM). He had 5,329 flight hours, including 1,097 hours on the EMB 120. The first officer was Kenneth Reece, age 29, who was the Pilot Flying (PF) on Flight 3272. Reece had 2,582 flight hours, with 1,494 of them on the EMB 120. +CVR on Comair 3272 (* = Expletive; ^ = Unintelligible word; = background sounds)SourceContentCaptainYeah, looks like it's your low speed indicator CaptainPower.

The National Transportation Safety Board very quickly has noticed similarities between this accident and American Eagle Flight 4184. The NTSB determined that the probable cause was inadequate standards for icing operations while in flight, specifically the failure of the Federal Aviation Administration to establish adequate minimum airspeeds for icing conditions, leading to a loss of control when the airplane accumulated a thin, rough accretion of ice on its lifting surfaces. A contributing factor was the crew's decision to operate in icing conditions while near the lower end of the flight envelope while the flaps were retracted. Comair had not established unambiguous minimum airspeed values for flap configurations and for flight in icing conditions. They also, against recommendation of the plane's manufacturer, failed to activate the deicing boots on the wings. This was because the Comair Flight manual recommendation was in contravention of the manufacturers due to a concern over "ice bridging", a concern held over from older planes that was no longer valid on newer generation planes like the Embraer 120. As the plane crash site is on private property, a memorial was built at the Roselawn Memorial Park in La Salle, Michigan, where unidentified remains of those killed in the crash are buried.

The investigation into the crash was covered in "Deadly Myth", a 2017 episode of Mayday, a Canadian television series about air crashes.
