The jet hit an airspeed of 500 knots (575mph), well above its operational limits, before cockpit data recordings stopped.
The flight and cockpit data recorders showed that the jet was cruising at a stable altitude of 32,000 feet when the plane made a sharp left and the crew contacted ground control requesting permission to climb to 38,000 feet.

The Dutch Safety Board says its preliminary report was based on the contents of the flight and cockpit data recorders, other communication with the plane, as well as forensic examination of the wreckage where possible.
Investigators relied on cockpit data, air traffic control and images for the new report, as the crash site in eastern Ukraine remains too dangerous to access amid fighting between government troops and rebels.
The Aviation segment include GPS-enabled navigation, VHF communications transmitters, receivers, multi-function displays, electronic flight instrumentation systems, automatic flight control systems, traffic advisory systems and traffic collision avoidance systems, instrument landing system receivers, surveillance products, audio panels, and cockpit data link system.
An initial reading of the cockpit and data recorders from the flight show that the Airbus 330 went into a high-altitude stall that the pilot was unable to rectify.
After the "deorbit burn," the commander and pilot in the cockpit monitored performance data on their computer screens.
Investigators said the cockpit and flight data recorders, sent to France, had been successfully downloaded despite damage.
Soon, however, the sounds will gradually begin to weaken, complicating the quest for the recorders and the secrets locked in them: cockpit conversations and data on the plane's altitude, airspeed and heading in the flight's final moments.
MEXICO CITY — Working amid dense thickets of thorny trees, rescue workers retrieved cockpit voice and data recorders on Friday from the wreckage of a plane that crashed in central Cuba, killing all 68 people aboard, Cuban media reported.
