Kurniadi reiterated that investigators have found no evidence of foul play in the disaster.

Transport Minister Jonan on Tuesday gave the first detailed information about the final minutes of Flight QZ8501 based on radar data. Data from the black box flight recorders would give a more detailed picture, Kurniadi said.

At 6:17 am on Dec 28, three minutes after air traffic control unsuccessfully tried to make contact and asked nearby aircraft to try to locate QZ8501, the A320 turned to the left and it began to climb from its altitude of 32,000 ft (9,750 metres), Jonan told a parliamentary hearing.

The rate of the climb increased rapidly within seconds to 6,000 ft a minute, before accelerating further to 8,400 ft a minute and finally 11,100 ft. The aircraft reached 37,600 ft just 54 seconds after it began to climb before it appeared to stall.

The aircraft began to fall at 6:18 a.m., dropping 1,500 ft in the first 6 seconds before reaching a rate of descent of 7,900 ft per minute until it reached 24,000 ft, at which point it disappeared from the radar.

Pilots and industry observers told Reuters that if an aircraft makes a rapid climb and start to lose speed, it would be likely to stall and suffer from a loss of control.
