Think you might find poor ol RHJ has had corrosion in it for a long time, considering it spent a while sitting outside at Thursday Is with the salt spray before moving into the hangar on Horn Is. Would be scarey if it got stripped right down.
Think you will find AH will have to pay if the 412 is off line for any substantial time, thats why "it will be finished in 4 - 5 weeks"
And for info the "crewies" are Observers, some with winch endorsements and a dodgy check and training system. Good place to get night hours though.
The front line pilots and observers are a good bunch and put up with a lot of ****e, doesn't sound like much has changed in the last few years from management.
