Beschrijving:
ATI Flight 12, a McDonnell Douglas DC-9-32, took off from Alghero Airport, Sardinia, Italy, at 00:10. The aircraft was bound for Rome-Fiumicino Airport with a planned stop at Cagliari on the southern part of the island of Sardinia.
The first officer contacted the controller at Cagliari at 00:23, asking for a weather report. The controller replied that runway 14 was in use, a wind from 190 at 8 knots, and a visibility of 7 km. He also stated there were thunderstorms without precipitation, south-east and south-west of the airport.
After contacting the Cagliari Tower controller at 00:26, the flight was cleared to descend to the transition altitude of 6000 feet. Having in front of them a consistent formation of Cumulonimbus clouds, the first officer radioed their intention to make a 360 turn to further lower the altitude and thus avoid the cloud formations.
The controller, not having traffic in the area, authorized the manoeuvre, and first officer then announced the intention to leave at 7500 feet for 3000 feet.
The controller then asked the flight if they had visual contact with the ground, but this was not the case. The clearance was amended to go down to 6000 feet instead of 3000 feet.
Art 00:30 the flight reported that it was in visual contact with the ground, and that it was about to leave 6000 ft for 3000 ft. The controller confirmed this, adding that it had started to rain at the airport in the meantime.
The aircraft however did not complete the planned 360 turn, thus finding itself with a different heading from that initially planned.
After reaching 3000 feet, the flight was cleared for the approach. The first officer confirmed this and announced that they would start the final approach with a slight deviation to the right of the beacon.
At 00:34 the first officer asked the controller to confirm that the ILS system was inoperative, which it was. At this stage of the flight the crew became unaware of their position. The captain believed he was flying over the sea, further south than the actual position of the aircraft, while the first officer rightly believed he was flying over the mountainous terrain of southern Sardinia.
In the last minute and a half of the flight, the captain asked the first officer to lower the undercarriage and continued the descent.
At an altitude of 2000 feet (610 m) the DC-9 hit the rocky mountainside of Conca d'Oru with the lower part of the fuselage, causing the aircraft to break up. A fire erupted. The point of impact was 18 km south-west of the airport.
