The crash of Air NZ A320, ZK-OJL just off France in 2008 was a result of the Pilots making a risky manoeuvre and poor maintenance by ground crews washing the A320 resulting in water getting into key instruments

No real surprises, as the preliminary reports had already indicated this.
The manoeuvre itself isn't necessarily risky, just doing it at the height this crew did leaves little room for error. The Airbus In Service Aircraft Test Manual requires an altitude block between FL140 and FL100 for this test. Doing it at approx 4000ft in the approach is a big no-no in my book, but that seems to be covered by the BEA commenting that the did not have experience in performing testflights, and therefore didn't appreciate the aims of the ISATM, and the reasoning behind the requirements contained therein.
