CAA today can find no evidence of level 6, either on a paper copy of the SRG 1119, or recorded electronically
The SRG 1119 when it reaches the CAA is scanned; there is no electronic data entry and I believe the paper copies are then destroyed. They simple answer is that they would have to look through all the scanned material from the last 5 years to find the ticked boxes and that is too much work. You could always ask to see it under FOI, then they would have to find it!
