An article in the Danish Magazine "Ingeniøren" (The Engineer) claims that the Dutch secretary general of the AEI (Aircraft Engineers International) Fred Bruggemann has said that the Investigation Board has spoken to several Turkish pilots who have flown the crashed plane in the days before the accident. They admitted that they had not reported the defect altimeter as they should have. He added that the AEI has contacted the plane mechanics in Turkey who confirmed that the log book did not contain anything about a defective altimeter.
The article describes the course of the accident as it is already mentioned here in several posts.
It says also that the plane crashed while the pilots were having a conversation. They noticed the critical situation and gave full power but it was too late.
It further says that the black boxes contained data and audio from the last 25 hours. That is several flights over several days. During the last 8 flights, the altimeter was defect a total of three times in the same way and in the same situation, including the last time, where the plane crashed. The pilots in those cases also noticed the defect altimeter but did not do anything about it.
Fred Bruggemann said that AEI has warned often about late logging.
