The collision avoidance system apparently failed to operate properly. The system from the 737 was examined, and it showed no traffic warnings prior
to the collision. When the crew was interviewed, they said they were warned of traffic 1,000 feet below them, but initially saw the BAE 125 flying
1,000 feet above
them, and descending through their altitude.
Five hours before the collision, the BAE 125 triggered multiple alarms on ATC radar for being at the wrong altitude. On the 10th, and 23rd of July,
as well as the 31st of August there were incidents that showed a problem with the altimeter on the aircraft. On the 23rd of July, the aircraft passed
an Arik Air 737 at the same altitude. The Arik crew had been informed that the 125 was at 32,000 feet when in reality they were at 31,000. The crew
insisted they were higher, and that there was more separation between the two aircraft, but the Arik 737 had descended to 29,000 by that point.
