In earlier January, the Canadair CRJ 200 aircraft smashed into the ground in a remote area of Sweden's arctic north, about 200 km northwest of the town of Gällivare. Both pilots, from France and Spain, died on impact.
Officials with the accident authority said the flight was perfectly normal for the first hour and 10 minutes.
But shortly before 11:20 p.m. on January 8, a navigation sensor failed and the pilot in command believed the plane was pulling upward and tried to correct the movement by pushing the nose of the plane toward the ground.
His co-pilots' instruments, however, were working normally. The report stated that if the two pilots had talked with each other and compared their indicators, the accident could have been avoided.
"About 13 seconds after the start of the event the crew were presented with two contradictory attitude indicators with red chevrons pointing in opposite directions," the report read.
Although the pilot in command received a warning message that the readings between the two pilots were different, the message disappeared within a few seconds.
