13 July 1982 – A Boeing 747 operating as Singapore Airlines flight SQ-21A between Singapore and Melbourne flew into volcanic ash from erupting Galunggung volcano and experienced multiple engine failures. A two-engine emergency landing was made at Jakarta and all four engines were replaced. 26 March 1991 – Singapore Airlines Flight 117, an Airbus A310-300 registered as 9V-STP, was hijacked by militants en route from Sultan Abdul Aziz Shah Airport to Singapore Changi International Airport, where it was stormed by the Singapore Special Operations Force. All hijackers were killed in the operation, with no fatalities amongst the passengers and crew. 31 October 2000 – Singapore Airlines Flight 006, a Boeing 747-400 registered as 9V-SPK, attempted to take off on the wrong runway at Taiwan Taoyuan International Airport (previously Chiang Kai-shek International Airport) while departing for Los Angeles International Airport. It collided with the construction equipment that was parked on a closed runway, killing 83 of the 179 on board and injuring a further 71 people. This was the first fatal accident involving a Singapore Airlines aircraft. The aircraft 9V-SPK was painted in a "Tropical" promotional livery at the time of the accident. The only other aircraft painted with the promotional livery, another 747-400 registered 9V-SPL, was immediately repainted with standard Singapore Airlines livery. 12 March 2003 – A Boeing 747-400 operating as Singapore Airlines Flight 286 from Auckland International Airport to Changi Airport was involved in a tailstrike while taking off from Auckland's Runway 23L, causing severe damage to the aircraft's tail and damaging the APU (Auxiliary Power Unit), causing in-flight APU fire warnings. The flight returned to Auckland with no fatalities or serious injuries on board. The cause was later determined to be an error in the pilots' calculations of the aircraft's takeoff weight and reference speeds, which caused the pilots to rotate the aircraft prematurely. 27 June 2016 – Singapore Airlines Flight 368, a Boeing 777-300ER registered as 9V-SWB with 222 passengers and 19 crew on board, suffered an engine oil leak during a flight from Singapore to Milan. The oil-leak alarm was sounded above Malaysia, two hours into the flight. During the emergency landing at the point of origin, Singapore Changi Airport, the right engine caught fire, leading to the right-wing being engulfed in flames. The fire was extinguished within five minutes after the plane landed. No injuries were reported. The aircraft was substantially damaged and repaired. 6 May 2022 – Singapore Airlines Flight 439, a Boeing 737-800, sustained a tailstrike during takeoff from runway 20 at Tribhuvan International Airport. The resulting incident depressurized the aircraft and forced it to divert to Kolkata, India. There were no injuries among the 165 passengers and 8 crew members on board. The tailstrike occurred during the takeoff at the airport was due to over-rotation by the PF, coupled with a likely tailwind with a component of about 10 knots along the runway. The rotation pitch rate was, at times, greater than 5° per second as recorded by the FDR. The pitch angle of 11.07° recorded also exceeded the 7° – 9° normal pitch angle range. 28 September 2022 – A drunken passenger on board the Singapore Airlines Flight 33 from San Francisco to Singapore made bomb threats and also inappropriately touched other people. The Republic of Singapore Air Force scrambled their F-16 Fighting Falcons to escort the plane to Changi Airport where the airliner was searched and the threat was declared to be false thereafter. 25 October 2022 – A Boeing 777-300ER registered as 9V-SWH and operating as SQ 319 from London Heathrow Airport to Changi Airport in Singapore with 280 occupants on board, diverted to Hang Nadim Airport in Batam due to adverse surface wind conditions and poor visibility caused by a thunderstorm over Singapore. As the aircraft approached Batam, the weather conditions had similarly deteriorated due to a thunderstorm over Batam and after three unsuccessful attempts at landing, the aircraft landed with a fuel quantity that was "significantly below" the final reserve fuel requirement of 3,024 kg. There were no injuries on board or any damage to the aircraft. 21 May 2024 – Singapore Airlines Flight 321, a Boeing 777-300ER (registered as 9V-SWM) with 211 passengers and 18 crew members on board from London Heathrow Airport to Changi Airport in Changi, Singapore, was diverted to Suvarnabhumi Airport in Bangkok after encountering severe turbulence en route over Irrawaddy Basin in Myanmar. Of the 229 people on board, 1 passenger died. All of the other 228 occupants survived, but 104 passengers and crew members were injured.
