We all know what the Board said. It is what they didn't say (or ask) that is important (in addition to the Rad Alt Tx/Rx being faulty and defective).
Tell me someone, do we now have adequate test equipment to carry out an SST?
Are the APs up to date yet, or amended to include, for example, a test to determine the system's ability to withstand and recover from a power interrupt? (Noting the evidence the Board were not permitted to hear about continual power interrupts in the Mk2 electrical system). In my day, the Power Interrupt Units lay unused because there was no AP to tell you how to use or fix them; and MoD have admitted the necessary contract didn't exist.
Is there a training course yet for 2nd/3rd line technicians, or is it still "Have a bash and never mind if the system is calibrated wrongly" (as ZD576's was). You see, informing pilots of range from a quite hard object wasn't considered important enough by AMSO.
Dare I say it - all basic airworthiness components.
