The 1974 Sterling Tehran accident happened when a Sud Aviation Caravelle, flight number 296 operated by Sterling Airways, experienced a landing gear failure as it was taxiing for take-off. The right main landing gear collapsed, which caused the right wing to hit the runway and brake, causing the fuel inside to ignite. The fire killed 15 passengers and injured 37 passengers and crew. The aircraft had been chartered by tour company Tjæreborg to take tourist around Asia, and was on the way back to Copenhagen when the accident happened. The accident came only two years after the crash of Sterling Airways Flight 296.

Aircraft
The aircraft involved in the accident was a Sud Aviation SE-210 Caravelle 10B3, manufacturer's serial number 266, registered as OY-STK. The aircraft made its first flight in 4 April 1970 and was delivered to Sterling Airways on 6 May 1970.

Passengers and crew
The aircraft was carrying 96 people of which 92 were passengers, two were pilots and two were cabin crew. The captain was 38-year-old Leif Knud Jørgensen, who had been with Sterling Airways since 1967, a captain since 1970 and had 9,600 flying hours. The co-pilot was Raimo Uski from Finland, who had 6,000 flying hours. The cabin crew consisted of 24-year-old Anne Bräuner and 22-year-old Bente Steffensen, both from Denmark. According to Danish newspaper Politiken, the nationalities of the passengers and crew were the following:

Accident
The Sud Aviation Caravelle had been chartered by travel agency Tjæreborg to take tourist on a tour around Asia. The tour had started in Copenhagen on 2 March 1974 and had taken the tourist to several cities, amongst them Shiraz, Bangkok, Hong Kong and New Dehli. The trip was on its 14th day, as it was returning back to Copenhagen and it was making a quick refueling stop in Tehran, before flying back to Copenhagen. As the aircraft was taxiing to the runway, the right main landing gear suddenly collapsed, causing the fuel tank in the right wing to rupture and spill out. As the right wing then scraped the runway, sparks ignited the fuel.

Investigation
Soon after news of the accident had reached Copenhagen, the Danish Accident Investigation Board dispatched a team to Tehran, along with technicians from the Danish police and experts in identifying bodies. The AIB team was to assist the Iranian investigation team. Before the investigation began it was suspected that either metal fatigue or loss of hydraulics that caused the accident. On the 30 March 1974 the AIB team released a statement about the accident. In the statement, they said the probable cause of the accident was failure of the right main landing gear. As the landing gear was torn off, the fuel tank inside ruptured, causing the fuel inside to spill out and get ignited by the sparks caused by the wing scraping the runway. According to Aviation Safety Network, the cause of the landing gear failure was a structural failure.
