Hi,
This is interesting ....
Crash Perpignan yet the failure of feedback!
(Page 84 of the BEA report). "An event on the A320 has been reported by an airline after the publication of the interim report."
In fact, there were 2.
The BEA does not give the dates of these events (or the name of company), but does not specify that they occurred after the accident on November 27, 2008. We have reason to think that these precursors two serious incidents occurred before the crash of a French company in Perpignan.
If all players in the accident on 27 November 2008 had benefited from these lessons learned, good awareness and good safety, it would have saved seven people dead and a plane.
Excerpts from the BEA report:
"The circumstances of this event were determined from maintenance records, the minutes of the aircraft equipment and the testimony of the copilot. The test probe 1 indicated a blocked probe to 5 degrees. Blockage of the probe 3 was found in the manual verification of freedom of movement. The record review indicates that icing residues and muddy water has probably led to the blocking probes on the flight.
During this flight, the alpha floor function did not activate. The PF found that the speed was less than ten knots in the V max expected alpha. The crew felt the aircraft sink and the captain decided to discontinue the investigation. The PF made a maneuver similar to a recovery stall. There was no stall warning.
On another A320 from the same operator, abnormal values of incidence were also found during a check flight. The three probes have been examined in the workshop, which revealed the presence of fluid in the bodies of two of them. "
These two incidents are precursors of the crash events in Perpignan.
