ATR 42

1980s

• 15 October 1987 – Aero Trasporti Italiani Flight 460, an ATR 42-312 registered as I-ATRH, crashed into Mount Crezzo, near Lake Como, Italy, killing all 37 people on board. The cause was determined to be the flight crew failure to activate deicing boots in the icing conditions they were flying in. This led to the aircraft stalling and losing control, which was worsened by improper actions by the crew and unusual control movements.
• 18 January 1988 – A Simmons Airlines ATR 42-300, registered as N421MQ, was minorly damaged after an in-flight fire near Waterloo, Iowa. None of the six passengers or crew were injured.
• 22 December 1988 – A Simmons Airlines ATR 42-300, registered as N427MQ, was on approach to Central Wisconsin Airport in Mosinee, Wisconsin, when it stalled and rolled 80° to the left and then 60° to the right. The crew successfully executed a stall recovery maneuver and none of the 37 people on board were injured. The accident was the result of an aileron hinge moment reversal in icing conditions.

1990s

• 26 November 1990 – An Executive Airlines ATR 42-300, registered as N971NA, was damaged after the left main landing gear collapsed during taxi at Saint Thomas Airport. None of the 47 people on board were injured.
• 17 April 1991 – Air Mauritius Flight 121, an ATR 42-310 registered as 3B-NAP, asymmetrically stalled over the Indian Ocean, although no one was injured. The aircraft encountered icing conditions, the crew did not activate the deicing boots, and when the crew disconnected the autopilot, the corrective inputs that were being applied stopped counteracting the effects of the icing.
• 17 July 1991 – Trans States Airlines Flight 7128, an ATR 42-300 registered as N425TE, had a left engine in-flight fire while on approach to Peoria International Airport in Peoria, Illinois. The aircraft landed safely and was evacuated without injures to any of the 19 passengers or crew. The cause was determined to be a failure of an interturbine duct bolt in-flight.
• 11 August 1991 – Ryanair Flight 123, an ATR 42-300 registered EI-BYO, stalled at 18,000 ft (5,500 m) over Ireland in icing conditions. The aircraft entered 12.6° roll to the left followed by a 50° roll to the right before the aircraft remained in a nose-up stall for twelve seconds. It leveled off at 14,000 ft (4,300 m) and no one was injured.
• 12 October 1991 – Britt Airways Flight 3894, an ATR 42-320 registered as N25811, was on the ramp at Sikorsky Memorial Airport preparing for departure. During the engine start for the right engine, an employee was hit by a propeller, causing fatal injuries.
• 4 March 1993 – Britt Airways Flight 3444, an ATR 42-320 registered as N99838 and operating for Continental Express, suffered an uncommanded autopilot disconnection and upset while on approach to Newark Liberty International Airport in Newark, New Jersey. The aircraft rolled 52° to the right that was only counteracted by the pilots commanding full left aileron. The cause was aileron hinge moment reversal in icing conditions.
• 12–18 March 1993 – An Ethiopian Airlines ATR 42-320 was hijacked by three men and one woman who demanded the aircraft to fly to Djibouti. The aircraft landed in Dire Dawa to refuel but was stuck there during negotiations with authorities. On 18 March, security forces raided the aircraft and in the ensuing conflict, two hijackers were shot dead and one out of the 26 other passengers were wounded.
• 4 April 1993 – Simmons Airlines Flight 4127, an ATR 42-300 registered as N422MQ and operating for American Eagle, was on the ground at Chicago O'Hare International Airport when a left engine fault message appeared in the cockpit. The crew called over a mechanic into the cockpit and the flight's departure was delayed. As the crew prepared to shut the right engine down, they switched off the aircraft's cabin lighting. At the same time, a baggage handler was preparing to load bags into the cargo hold when she was struck by a propeller on the right engine, causing fatal injures.
• 25 July 1993 – Flagship Airlines Flight 4944, an ATR 42-300 registered as N242AT and operating for American Eagle, suffered a ground collision with Saudi Arabian Airlines Flight 039, a Boeing 747-300, at John F. Kennedy International Airport in New York, New York.
