KLM Cityhopper Flight 433 was a Saab 340B, registered as PH-KSH, which crashed during an emergency landing in 1994. Flight 433 was a routine scheduled flight from Amsterdam, the Netherlands, to Cardiff, Wales.
The aircraft took off from Amsterdam at 12:19 pm. 11 minutes after takeoff, at 12:30 pm, the crew mistakenly believed that the number 2 engine suffered from low oil pressure because of a faulty warning light. After shutting down the number 2 engine, the crew request to return to Amsterdam Schiphol Airport. On short final (the last stage of flight before landing), at a height of 90 feet, the captain decided to go-around (abort the landing and try again) and gave full throttle. However he only gave full throttle on the number one engine, leaving the other in flight idle. Because of this, the airplane rolled to the right, pitched up, stalled and hit the ground at 80 degrees bank.
