Unfortunately it is possible that the incumbent will have a say in his replacement, unless this is a real clear out, instigated from above, you may be in for more of the same! If it is a clear out then deputies will possibly follow quite soon.
What might help the pilot cause is if the AMEs, as a body, made representation to CASA, but given the level if dissatisfaction already expressed here it is hard to believe that the AMEs haven't already done that.
