IMO:
That, may be determined by the Bean-counters at Headquarters. Why haven't they been scrapped yet, if they are worthless to the fleet? The answer may iin fact lie with the accountants in charge.
As long as Arpey is paying leases on the planes, they are assets, albeit unused assets, right?
Senario: Let's wait till the profits start to appear, then we can take a special charge against the gross profits by figuring the losses incurred on the A-300.
Then the Arpeys in the Co. can take more bonuses as they reward themselves for doing a fine job on the ballance sheet.
And everyone knows that that is more important than employee moral, right?
So in the end, after all the math is done, the Net Profit will be less, and there will be smiling faces in Arpey's office.
What I am saying is that, there may be a strategy involved in holding off on the scrapping until the time is right. After all, in a bad economy, the cost to do maint. on those planes is probably more than what they are worth, assuming parts are still available.
The parts issue is one more facet of the heavy maint issue for the A-300. Airbus may have said that they can't guarantee parts availablity for the dang things.
Would you start a paint job on your car if you had no paint?
Does this make sense, or am I way off in Left Field here?
