Rudder ratio actually, but never the less this is not uncommon. Especially if the job entails operating at heights or specialist equipment. The OH&S nazzis have seen to that.
Despite what you may think sickofqf, out stations seem to have a different interpretation of "big" or "highly complex" jobs but that is not what we are discussing here. Irrespective of local disquiet these guys would still have been sent to rectify the defect. If as you are implying this is a routine task carried out in Perth, then why did the locals not take the opportunity to dive into the task and make sure they took their time to aquit it in a leasurly fashion observing necessary shift handover briefings etc.....

Lay off Syd Base, no one there has done anything to undermine the Perth guys.
