I don't want to get into a technical debate over matters I am no expert in. The report goes into very fine detail, and is clear:
- There is a procedures to "wash" the Aircraft - it was not followed
- It involves protecting the AoA vanes - they were not
- Excess pressure was used, for too long, at the wrong angle
- Your vanes might be fine, but can they really stand up to a pressure wash on them as close quarters?
- The report is clear that water cannot, in normal use, get in.
- In fact, the seals etc. were probably what held the water in there for 3 days
And as ever, this was just a contributory factor. The aircraft was still deliberately flown very slowly, at low altitude, and trim (available) not used to aid recovery. The AoA sensors not working just removed protections and made it somewhat a normal aeroplane
