Lord Tyler asked Her Majesty's Government: What percentage of mandatory occurrence reports submitted to the Civil Aviation Authority relating to contaminated air are investigated by the Air Accident Investigation Branch. [HL4092]
Lord Davies of Oldham: In the past 10 years, the total number of contaminated air incidents recorded on the Civil Aviation Authority database was 347. The number of these investigated by Air Accidents Investigation Branch was 23. This equates to approximately 7 per cent. of the total.
AOPIS COMMENT:
23 events investigated is not 7% as the Civil Aviation Authority database is only representative of less than 4% of events. Of the 23 events investigated by the UK AAIB, they never once talked to any of the crews medical representatives or thought to carry out any extra medical testing.
