From the Wikipedia article
Asiana Airlines Flight 733 was a domestic Asiana Airlines passenger flight from Seoul-Gimpo International Airport to Mokpo Airport, South Korea. The Boeing 737-500 operating the flight crashed on 26 July 1993, in the Hwawon area of Haenam County, South Jeolla Province. The cause of the accident was determined to be pilot error leading to controlled flight into terrain. 68 of the 116 passengers and crew members on board were killed. The crash resulted in the first hull loss of a 737-500.
Accident
On 26 July 1993, flight 733 departed Gimpo International Airport in Seoul, bound for Mokpo Airport, for a scheduled arrival at 15:15. At that time, the weather conditions in Mokpo and Yeongam County area consisted of heavy rain and wind. However, the weather conditions were not enough to delay the arrival time. The flight planned to land on runway 06. The aircraft made its first landing attempt at 15:24, which failed, followed by a second landing attempt at 15:28, which also failed. At 15:38, after two failed landing attempts, the aircraft made a third attempt. The twin-engine plane then disappeared from the radar at 15:41. At 15:48 the aircraft crashed into a ridge, Mt. Ungeo, at 800 ft above sea level. At 15:50, the wreckage was found near Masanri, Haenam County, South Jeolla Province about 10 km southwest of Mokpo Airport. The news was reported by two surviving passengers who escaped from the wreckage and ran to the Hwawon-myeon branch of the village below the mountain.
Investigation and cause
Cause
After the crash, Asiana Airlines announced that the plane had been delayed by three landing attempts and that it appeared to have crashed. The runways did not have an ILS installed. Mokpo Airport was equipped with only a VOR/DME, resulting in the pilots performing multiple landing attempts, contributing to the accident. A prosecutor in charge of investigating the accident concluded that the aircraft, having disappeared from the normal flight route, had made an unintentional landing with the pilots having misunderstood the situation. Both pilots were killed in the crash. Chung Jong-hwan, the director general of the Ministry of Transportation, said that captain Hwang's actions caused the crash. An inquiry found pilot error was the cause of the crash when the plane began a descent while it was still passing over a mountain peak. The flight recorders were found and they recorded that after the third attempt, the crew told the control tower that the aircraft was veering off course. According to the cockpit voice recorder (CVR), captain Hwang flew the aircraft below the minimum safe altitude (1600 ft), as he said, "okay, eight hundred," a few seconds before impact.
