Hi,
Turbine D
You need to both go back and review the data presented in the BEA Interim report #2, starting on page 65. There you will learn there were indeed 9 events on Air France aircraft where loss of speed indication at high altitudes occurred. Seven events occurred between May 2008 and October 2008. All were on A-340 aircraft. You make it seem Air France sat on its hands and did nothing which was not the case at all. After the first event in May 2008, the second occurred in July 2008. Air France reported to Airbus the incident after the July 2008 occurrence and events thereafter. Air France then reported to Thale the worsening problem in October 2008. Then two new events occurred, one being the first one on an A330 aircraft. After ongoing discussions between parties including EASA, Air France on April 27, 2009 issued a modification to replace all pitot probes on all their long range A-340/A-330 aircraft with the first replacement batch of probes arriving a week or so before the AF447 accident. Review the tables of known events, at the time of the BEA report, starting on page 100 where at least 2 pitot tubes were blocked with ice.
AF .. Airbus ..EASA .. Thales .... even DGAC ..
One actor is missing ... the BEA
Where are inquiries .. investigations and reports (recommendations) of the BEA concerning all the pitots events (incidents) concerning french registered aircraft prior AF447 event ?
