• 13 June 1991 – Flight 376, a
Boeing 727 (HL7350) operating a domestic flight from
Jeju to
Daegu, performed an unexpected
gear-up landing at Daegu. The crew failed to read out the landing procedure checklist and therefore did not select the gear down option. Subsequent investigation revealed that the pilot instructed the co-pilot to pull the fuse case from the warning system because the repeated warnings that the landing gear was not deployed were "irritating and distracting". With the warning horn disabled, the Korean pilot brought the plane in and slid down the length of the runway on the central structural rib in the
belly of the aircraft. There were no serious injuries but the aircraft was written off. The police applied for an arrest warrant for the captain and the first officer, but controversy arose as the prosecutor rejected the application and investigated it without physical detention, but
Joo Ho-young, a judge who later became a member of the National Assembly, said in a trial ruling held in January of the following year, "The heavy responsibility of punishment under the criminal law is inevitable that defendants who are tasked with safe transportation of passengers did not follow basic air operation rules and caused an accident that could kill all 120 passengers." Captain Lee In-sung was sentenced to October in prison, and First Officer Kim Sung-joong and Flight Engineer Park Il-sung were sentenced to August in prison, and they were arrested in court. The gear-up landing blew up the lower part of the aircraft, ultimately rendering it inoperable, and on July 27, 1992, Korean Air donated the aircraft for practical use to
Inha Technical University, a member of the same Hanjin Group, after disassembling the remaining aircraft at Daegu International Airport in August 1991. • 10 August 1994 –
Flight 2033 was an
Airbus A300 operating a flight from
Seoul to
Jeju. During the approach into Jeju, the aircraft approached faster than usual to avoid potential windshear. Fifty feet above the runway, the co-pilot who was not flying the aircraft decided that there was insufficient runway left to land and attempted to perform a go-around against the captain's wishes. The aircraft touched down beyond the runway threshold. The aircraft could not be stopped on the remaining of runway and overran at a speed of 104 knots. After striking the airport wall and a guard post at 30 knots, the aircraft burst into flames. The cabin crew was credited with safely evacuating all passengers although only half of the aircraft's emergency exits were usable. There were no fatalities, but the aircraft was written off following the crash. • 22 September 1994 – Flight 916F from
Zürich to
Busan was operated by a Boeing 747. Eight days prior on 14 September, the aircraft had encountered a severe hailstorm over
Elba,
Italy, which led to a near miss incident. The aircraft sustained severe damage to the radome, cockpit windows and engines but managed to reach
Zürich safely. Some repair work was done, but the aircraft needed to be ferried to
Busan for final repairs.
Boeing released the aircraft with some takeoff performance changes, which included a limited gross weight of and increased takeoff speeds for V1, V2 and VR by 15, 17 and 14 knots respectively. The aircraft was cleared for a Runway 14 takeoff and ZUE 5P departure. After a long takeoff run, the aircraft lifted off the runway at the very end and climbed slowly. At 900 meters beyond the runway threshold, the aircraft cleared some adjacent buildings at lengths fewer than 50 meters. Subsequent investigation found that despite clear instructions to reduce weight, the crew had overloaded the aircraft at . • 6 August 1997 –
Flight 801 was a
Boeing 747-3B5 operating a flight from
Seoul, South Korea to
Agana, Guam, The crew attempted a night-time approach to Guam's runway 06L. Flight 801 had descended 800 feet below the prescribed altitude, striking the 709 feet
Nimitz Hill at a height of 650 feet and crashed in a jungle valley, breaking up and bursting into flames. 228 occupants were killed in the crash. Subsequent investigation found that the captain's failure to adequately brief and execute the non-precision approach, and the first officer's and flight engineer's failure to effectively monitor and cross-check the captain's execution of the approach, led to the crash. The incident was the first and only fatal crash involving the Boeing 747-300. Other contributing factors were the captain's fatigue and Korean Air's inadequate flight crew training. • 5 August 1998 –
Flight 8702, a
Boeing 747-400 operating a short flight from
Tokyo to
Seoul, departed Tokyo at 16:50 and was scheduled to arrive at Seoul at 19:20. Inclement weather at Seoul forced the flight crew to divert to
Jeju. The aircraft took off from
Jeju at 21:07 bound for Seoul. On landing in Seoul, the 747 bounced multiple times and slid 100 meters off the runway before coming to a stop in a grassy area. There were no deaths but some were injured; the aircraft was also written off. • 15 March 1999 –
Flight 1533 was operated by a
McDonnell Douglas MD-83 from
Seoul to
Pohang. Weather at Pohang was poor with degraded visibility and gusty 25 knot winds. The pilot failed at the first attempt to land. After the second approach, the plane touched down but overran the runway. The aircraft skidded through 10 antennas, a reinforced barbed wire fence and came to rest against an embankment. The landing broke the fuselage in half. The airline no longer operate this route as of October 3, 2023, as this route is now being operated by
Jin Air. • 15 April 1999 –
Cargo Flight 6316, a cargo flight operated by a
McDonnell Douglas MD-11 from
Shanghai to
Seoul, crashed shortly after takeoff southwest of
Shanghai Hongqiao International Airport. Investigations revealed that the Korean co-pilot's repeatedly misunderstood the instructions provided by the tower; the tower was relaying information in
meters which the pilots confused with
feet. The aircraft climbed to 4,500 feet and the captain, after receiving two wrong affirmative answers from the first officer that the required altitude should be 1,500 feet, thought that the aircraft was 3,000 feet too high. The captain then pushed the control column abruptly forward causing the aircraft to start a rapid descent. Neither was able to recover from the dive. The plane plunged to the ground, hitting housing for migrant workers and exploded. All three crew members aboard the aircraft and five on the ground were killed; 37 on the ground were also injured. • 22 December 1999 –
Korean Air Cargo Flight 8509 was operated by a
Boeing 747-2B5F from
London Stansted to
Milan Malpensa. After takeoff from London Stansted, the aircraft banked to the left and plummeted into the ground. Subsequent investigation revealed the Captain’s ADI was faulty and that maintenance activity at
London Stansted Airport was done improperly and the pilots did not respond appropriately to warnings during the climb after takeoff despite prompts from the flight engineer. The captain maintained a left roll control input, rolling the aircraft to approximately 90 degrees of left bank and there was no control input to correct the pitch attitude throughout the turn. The first officer either did not monitor the aircraft attitude during the climbing turn or, having done so, did not alert the commander to the extreme unsafe attitude that had developed. Investigators subsequently suggested, among other things, that Korean Air had altered training materials and safety education to meet the "unique" Korean culture. All four crew members were killed in the crash. == 2010s ==
