...the real point is they (DJ) don't carry enough of the 'right' spares and furthermore they don't have the spares they do have in the right places. I'm told the guys in the other ports get a bit peeved at nearly always seeing the bit they want as "n/r" on the system or the entire stock is in Brisbane - and then a geat pile of 'xyz' at that. Instead of responding to a problem when it exists, why not try a bit of anticipation. The probability of failure/breakdown/life expired/etc is after all why Boeing (etc) suggest, to buyers of their products, a spares float consisting of xyz. Their (Boeing etc) figures are based on worldwide fleet experiences and data from ventors of the OEM - be that an actuator, hose or screw etc. I am lead to believe that the way DJ look at spares requirements is more on 'how much does it cost' than any other data considerations or the ramifications of not having it. Sadly, Initial Provisioning is an art form which DJ have yet to appreciate.... and try to catch up on.
