Beschrijving:
On 17 June 2003 at 08:21 an Onur Air Boeing McDonnell Douglas MD-88 registered as TC-ONP contacted Groningen Airport Eelde tower for landing on runway 05. The flight with number OHY 2263 originated from Dalaman (Turkey). On board were 7 crew members and 146 passengers. During the non-precision approach, the aircraft was not properly lined up and too high for landing. A go-around was initiated at 08:28. The published missed approach procedure (i.e. climb 2,000 feet on track 053, contact ATC) was not followed. Instead, a left hand visual circuit was made at an altitude of 1,000 feet. ATC did not challenge this deviation from the standard procedure. The aircraft made an uneventful landing on runway 05 at 08:33.
At Groningen Airport Eelde 76 passengers disembarked. The 70 passengers with destination Maastricht-Aachen Airport remained on board. An additional 72 passengers with destination Dalaman boarded the aircraft making a total of 142 passengers on board.
The load and trim sheet as prepared by the crew assumed 70 passengers in compartment #1 and 70 passengers in compartment #2. Since seat allocation was not used for the passengers (free seating policy), the actual distribution differed. The purser stated that the aft part of the cabin had not been occupied by passengers.
According to the load and trim sheet the centre of gravity for takeoff (TO-CG) was at 11.1% mean aerodynamic cord (MAC) and the takeoff mass was 127,529 lb (57846 kg). During flight preparation, the "Onur Air takeoff performance chart with optimum flap setting for Groningen Airport Eelde runway 23" was used. This flaps setting was 24 degrees.
At 09:09 the start-up clearance for runway 05 as runway in use was received. On request of the flight crew runway 23 was approved for departure by ATC.
Engine start and taxi-out were uneventful. During taxi the flight was cleared for a domestic flight from Groningen Airport Eelde to Maastricht Aachen Airport as OHY 2264. The final destination was Dalaman (Turkey). At 09:18 the aircraft received takeoff clearance for runway 23.
The captain stated that after the aircraft was lined up on runway 23 the takeoff was initiated. After the throttles were advanced, the stabilizer warning sounded. The throttles were retarded and the aircraft stopped. The captain stated that the aircraft had moved five to six meters before it stopped. Eyewitnesses reported that 50 to 150 meters were used before the takeoff run was resumed. On the runway checks were performed. The stabilizer position was changed from 6.8 to 7.2 degrees aircraft nose up (ANU). Thereafter the crew initiated a static engine spin-up. Again the stabilizer warning sounded. The crew released the brakes and started the takeoff roll. During the entire takeoff roll the warning sounded continuously.
When attempting to rotate the captain experienced a heavy elevator control force. The captain stated that he needed much more than normal back pressure on his control column to lift the nose. He felt "it was impossible to make the takeoff", and as the nose did not rise he decided to reject the takeoff. Rejection was initiated at 128 knots. Brakes and reversed engine thrust had been applied. The aircraft overran the runway end with a speed of approximately 75 knots. During the deceleration in the soft soil, it hit the approach lighting system, including the concrete structures embedded in the ground. It came to a stop approximately 100 meters beyond the runway end. There was no fire. All occupants evacuated the aircraft safely. Some of them returned to the aircraft and re-entered it, to pick up their belongings. In addition, the pilots remained on board and only left the aircraft when instructed to do so by the fire brigade.

Probable Cause:

Waarschijnlijke oorzaak (oorzaken)
- De bemanning hervatte de start en ging verder terwijl de stabilizer warning, vanwege een nog altijd onjuiste stabilizerinstelling, opnieuw werd geactiveerd.
- Het feitelijke zwaartepunt tijdens de start (TO-CG) lag veel meer naar voren dan de bemanning veronderstelde. Een gevolg was dat de horizontale stabilizer niet was ingesteld op de positie die nodig was voor de start.
- Het veel meer naar voren gelegen TO-CG droeg bij tot een abnormaal grote stuurkracht van het hoogteroer bij de rotatie waardoor de piloot de start voorbij de beslissingssnelheid afbrak. Dit had tot gevolg dat het vliegtuig aan het einde van de startbaan van de baan geraakt is.

Factoren die hebben bijgedragen
- Door zijn ontwerp biedt het configuratiewaarschuwingssysteem van het vliegtuig geen bescherming tegen een incorrecte TO-CG invoer.
- Het vliegtuig was niet uitgerust met een systeem dat gewicht en gewichtsverdeling kon meten.
- Afwijkingen van operationele factoren stapelden zich op, resulterend in een ongunstige vliegtuigprestatie tijdens de start.
- De cockpitbemanning schoot ernstig tekort.
