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

The wreckage of Air Littoral Flight 701A

• 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 and operating for Continental Express, 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 City. The outboard section of the left wing on the Boeing 747 was damaged while the vertical stabilizer and rudder of ATR 42 was substantially damaged. The cause was the captain of the Boeing 747 misjudging his clearance in distance between his aircraft and the ATR 42 as he was making a cabin announcement.
• 28 January 1994 – A Continental Express ATR 42-320, registered as N15818, was cruising at 16,000 ft (4,900 m) near Burlington, Massachusetts, with wing, engine, and propeller deicing systems activated when the autopilot disconnected at 144 kn (166 mph). The aircraft stalled and the left ailerons deflected uncommanded. The aircraft reached a bank angle of 54° left before the pilots recovered and landed safely without any injuries.
• 11 February 1994 – A CityFlyer Express ATR 42-300, registered as G-BUEB, was taxing to the gate when the right engine collided with a ground power unit at Gatwick Airport. An evacuation was conducted in which two passengers were minorly injured. During the aircraft's taxi from Dublin Airport in preparation for takeoff, the number two DC generator failed, which resulted in the toe brakes of the aircraft to become less effective when the crew tried to slow down the aircraft.
• 13 March 1994 – Inter-Canadien Flight 1678, an ATR 42-300 registered as C-GIQV, was climbing through 17,000 ft (5,200 m) out of Val-d'Or when an explosion from the right engine caused a rapid decompression. The flight crew shut down the right engine, initiated an emergency descent, and safely landed at Montréal–Trudeau International Airport with only 3 injuries out of the 26 people on board. A propeller blade on the right engine failed due to corrosion induced by chlorine being introduced during manufacturing.
• 21 August 1994 – Royal Air Maroc Flight 630, an ATR 43-312 registered as CN-CDT, crashed into the Atlas Mountains shortly after takeoff from Agadir–Al Massira Airport, killing all 44 people on board. The crash was caused by the captain intentionally disconnecting the autopilot and flying the aicraft into the ground.
• 3 April 1996 – A Simmons Airlines ATR 42-300, registered as N421MQ and operating for Continental Express, was damaged after the left main landing gear collapsed during landing at Traverse City Airport. None of the 36 people on board were injured.
• 20 November 1996 – A Simmons Airlines ATR 42-300, registered as N47AE, was damaged after the right main landing gear collapsed during landing at Cincinnati/Northern Kentucky International Airport. None of the 44 people on board were injured.
• 30 July 1997 – Air Littoral Flight 701A, an ATR 72-500 registered as F-GYPE, overran the runway at Florence Airport in Italy, killing the captain and injuring the 16 other people on board. The flight crew conducted an unstable approach and ignored warnings from the ground proximity warning system, which resulted in the aircraft landing on the runway at a speed too high to stop safely.
• 20 January 1998 – An Italair ATR 42-312, registered as EI-COC, suffered a hard touchdown and a runway excursion while landing at Alghero–Fertilia Airport. The aircraft was written off as a result.
• 21 January 1998 – Continental Express Flight 3332, an ATR 42-320 registered as N15827, was substantially damaged after the right engine caught fire during landing at Bradley International Airport. One flight attendant was injured during the evacuation. The cause was an improper maintenance procedure leading to fuel being spilt and coming into contact with the engine bay.
• 16 March 1999 – Pantanal Linhas Aéreas ATR 42-320, registered as PT-MFI, was damaged beyond repair after a right engine fire on the runway at Mucuri Airport. All 14 people on board the aircraft evacuated before the fire, influenced by the wind, burned the aircraft's fuselage. An improper fuel heater caused the fire.
• 11 October 1999 – An Air Botswana ATR 42-320, registered as A2-ABB, was stolen by an Air Botswana pilot at Sir Seretse Khama International Airport in Gaborone. After flying around the airport for two hours, he crashed the aircraft into two other Air Botswana ATR 42's on the apron, killing himself, the only occupant on any of the three airplanes.
• 12 November 1999 – Si Fly Flight 3275, an ATR 42-300 registered as F-OHFV and operating for the United Nations, crashed into a mountain while approaching Pristina International Airport in Kosovo, killing all 24 people on board. The investigation determined that the primary causes of the controlled flight into terrain were a lack of procedural compliance for the approach procedure in low visibility conditions, air traffic control's failure to properly track the flight, and a lack of a ground proximity warning system.
• 26 December 1999 – An Aérospatiale ATR 42-310, registered as F-WQJN, was damaged beyond repair at the ground at Dinard–Pleurtuit–Saint-Malo Airport during a storm.
