Following the occurrence the ILS of runway 12R was downgraded from CATIII to CATI.
Passengers reported immediately after takeoff something broke, the aircraft shook, they then entered a holding for about an hour before returning to land at Belgrade. They were quickly escorated off the aircraft, they weren't told anything except it was a minor incident, however, they could see something had broken off the left wing.
The airline reported the aircraft returned due to technical reasons and landed safely.
According to ADS-B data the aircraft lined up runway 30L via taxiway D5, commenced takeoff in direction of runway 30L, was still on the ground at position N44.8274 E20.2846 and climbed through 50 feet AGL at position N44.8335 E20.2673 just ahead of the motorway.
According to ATC recordings heard by The Aviation Herald the aircraft was cleared to line up runway 30L at D6, however, the aircraft entered the runway at D5. ATC queried the crew and cleared the aircraft to backtrack the runway to D6, the crew however replied they were able to depart on 1273 meters from D5. The aircraft subsequently was cleared to takeoff. Shortly after takeoff the crew advised they needed to go back immediately, they hit something on departure, tower instructed an aircraft already on runway to vacate the runway and instructed all traffic to hold position and to maintain radio silence and if on the runway vacate the runway.
Within the ATC recording the decisive communication is transcribed by The Aviation Herald:
Twr: Air Serbia 86C, Tower.
Twr: Air Serbia 86C, Tower.
radio: click sound
Twr: Are you familiar that you entered runway by Delta 5 Intersection?
Crew: Yes, TORA is two two, actually, sorry, TORA is ah One Two Seven Three Meters, I assume that is not enough
Twr: Okay, Calculate and call me, if you need you can commence backtrack and line up abeam Delta Six.
Crew: Okay, able to depart via Delta Five
On Feb 22nd 2024 Serbia's Traffic Accident Research Center reported, that the occurrence was rated an accident and is being investigated. During pre-flight preparations the crew planned for a departure from runway 30L via intersection takeoff from taxiway D6. The crew received taxi instructions from their stand to holding line D6 via taxiways F,G and A, which the crew read correctly back. The crew subsequently reported they were approaching D6 and were cleared to line up the runway via D6. Tower subsequently urgently called the crew querying them whether they were aware of having lined up at D5. The crew advised they needed a minute to compute their performance and computed the performance at the first officer's tablet computer. While the crew were doing their calculations tower offered the crew to backtrack the runway to D6, however, the crew confirmed they were able to take off. Tower again queried whether they were aware of D5, the crew affirmed, tower subsequently cleared the aircraft for takeoff. Tower subsequently observed the aircraft taking off leaving a lot of dust behind and climbing very slowly out. The flight crew reported they had selected full takeoff thrust normal acceleration until 80 knots, however, at 100 knots they realized they were running out of runway surface. Considering the remaining runway ahead the crew decided it was safer to continue as they estimated the aircraft would soon lift off. The crew firewalled the engines and to lift the nose of the aircraft in order to use the maximum length of runway available. The aircraft began to shake as they left the runway surface, then hit an object. Following lift off the crew received indications of problems with a number of systems amongst them flaps and bleed air. After working the checklists the crew declared Mayday reporting they had hit some object on departure and decided to have the landing gear checked during a low pass over the aerodrome, during which ground staff did not observe any problem with the landing gear. Due to the problems with the flaps the crew decided to use a higher speed than normal for landing and landed on runway 30L without further incident. The crew taxied to the apron with emergency services in trail. After arriving at the stand ground staff informed the crew there was a fuel leak from the left hand wing, the crew quickly shut the engine and other systems down, emergency services started to treat the fuel leak. After passengers and crew had disembarked authorities ordered the aircraft to be removed from the terminal to a safer place. The fuel leakage continued to the next day despite the fuel had been pumped out of the tank. The aircraft sustained substantial damage.
Tyre tracks were found past the end of the paved surface colliding with a number of approach lights, the aircraft impacted the ILS monitoring antenna 145 meters past the paved surface leaving only the concrete surface with broken cables behind, some parts of the antenna were found 175 meters past the paved surface and about 60 meters past the aerodrome fence, other parts were embedded in the left hand wing of the aircraft. A few meters after that foundation a hole of 60cm diameter was found in the ground with parts of the aircraft embedded. About 160 meters past that concrete contact marks of the tail section of the aircraft's fuselage were found on the ground. No traces of the aircraft's nose wheels were found on the ground, while tracks of the main gear were found until the monitoring antenna. It thus can be concluded that the aircraft went past the runway end with both main gear struts carrying most of the weight and transmitting vibrations onto the airframe. The aircraft hit the monitoring antenna and its foundation with the left hand wing.
The preliminary probable cause is stated to have been: "One of the probable causes of this accident is the inadequate assessment of take-off parameters during the pre-flight preparation of the flight crew of the aircraft, and after the decision to take off with a shorter runway length compared to the initially planned one."
