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. The captain retarded the no. 2 engine power lever slowly to flight idle, and the crew requested 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.[1] Because of this, the airplane rolled to the right, pitched up, stalled and hit the ground at 80 degrees bank.[2]


The aircraft involved was a Saab 340, registration PH-KSH which had first flown in 1990. PH-KSH makes an appearance in the 1993 Christmas special, "Sea Fever", of the British sitcom Keeping Up Appearances.

Result of crash

Of the twenty-four people on board, three were killed, including the captain. Nine others were seriously injured.
