From the report:
The crew not taking into account the stall warning, which could have been due to:
- A failure to identify the aural warning, due to low exposure time in training to stall phenomena, stall warnings and buffet,
- The appearance at the beginning of the event of transient warnings that could be considered as spurious,
- The absence of any visual information to confirm the approach-to-stall after the loss of the limit speeds,
- The possible confusion with an overspeed situation in which buffet is also considered as a symptom,
- Flight Director indications that may led the crew to believe that their actions were appropriate, even though they were not,
- The difficulty in recognizing and understanding the implications of a reconfiguration in alternate law with no angle of attack protection.
