All of the four aircrew involved in the crash had only limited flying time in the months before the crash. It would appear that none of them had noticed that the aircraft had stalled until shortly before impact, as indicated by a failure to apply standard recovery techniques to the aircraft once it entered the stall. The investigation reported that even if the proper stall recovery techniques had been applied, it was unlikely that the accident could have been prevented as the aircraft was already flying too low to be recovered.[1][page needed]
