ALL aviation accidents and serious incidents are made by experts...
Some statistics
Years after years the picture unfortunately is the same...
A last but positive comment!

1. Experienced crews:
• more than 6000 hours flying time
• More than 1000 hours on the aircraft type,
  
  
2. Judged pretty good vocational by the other company crew members,
   
   
3. most of them were pretty well trained about the aircraft procedures,
   
   
4. most of them were pretty well trained about the company procedures,
   
   
5. most of them they were well trained to CRM,
6. All were very motivated crews.

In conclusion, the experience ONLY does not prevent from being involved in accident.

Some statistics
From NTSB during 1970 to 2000.

   • the 81% of the accidents/serious incidents occurred when the Captain was the Pilot Flying (PF),
     
     
   • more than 50% of the accidents involved FO during their first year of (transport) pilot,
     
     
   • 73% occurred on the first day crew was flying together,
     
     
   • 44% occurred on the first flight leg of the crew's first flight together,
     
     
2. About their behavior:
   • 96% of all the violations in flight are from origin human...
     
     
   • 83% of the human errors in the important accidents are the fact of defects of monitoring or questioning,
     
     
   • 90% of the impacts with the ground involve crews not observing the procedures,
     
     
   • 69% of the communication errors are done by FO,
     
     
   • When pilots are in a hurry or under pressure:
     • 63% of the errors are carried out during preflight,
       
       
     • 34% during taxi,
       
       
     • 80% are carried out during strong workloads,
       
       
     • 48% show clearance or trajectory respect default,
       
       
3. About the phase of flight:
• 78% of the important accidents take place during either takeoff or the landing,
  
  
• 80% of the errors during taxi lead to an accident,
  
  
4. About the FMS:
• 48% of the errors involve an error of trajectory follow-up during departure,
  
  
• 78% involve a bad coordination between the crew members,
  
  
• FMS errors have twice more chance to be notified by Air Traffic Control than by the crew member.
