The French accident investigating agency BEA released the second interim report of their investigation into the fatal Air France Airbus A330 accident in June 2009. The airplane crashed into the Atlantic Ocean, killing all 228 on board.
This report covers further analysis of:
– the elements of wreckage recovered,
– the meteorological situation,
– the maintenance messages transmitted by ACARS,
– the certification and the continuing airworthiness of the Pitot probes,
– events where speed inconsistencies were encountered in cruise.
On the basis of this work, BEA recommends that EASA and ICAO:
1. extend as rapidly as possible to 90 days the regulatory transmission time for ULB’s installed on flight recorders on airplanes performing public transport flights over maritime areas;
2. make it mandatory, as rapidly as possible, for airplanes performing public transport flights over maritime areas to be equipped with an additional ULB capable of transmitting on a frequency (for example between 8.5 kHz and 9.5 kHz) and for a duration adapted to the pre-localisation of wreckage;
3. study the possibility of making it mandatory for airplanes performing public transport flights to regularly transmit basic flight parameters (for example position, altitude, speed, heading).
In addition, the BEA recommends that ICAO:
4. ask the FLIRECP(19) group to establish proposals on the conditions for implementing deployable recorders of the Eurocae ED-112 type for airplanes performing public transport flights.
And BEA recommends that EASA :
5. undertake studies to determine with appropriate precision the composition of cloud masses at high altitude, and
6. in coordination with the other regulatory authorities, based on the results obtained, modify the certification criteria.
