Gossip from the crewroom/workface/'orses mouth...
...is that they are also very short of engine stands to put the chronically challenged engines on.
Nowadays a highly paid consultant and computer will work out how many engines stands you will need by using a formula involving
Number of aircraft on fleet
Projected flying hours per month
Hours between servicing
Life of component parts
and so on
Trouble with these plans is that they're all bollocks
Heroic endeavours by the groundcrew though. An engine change on a C130 J could involve three aircraft. One aircraft to place the broken engine on, another to steal a good engine off, and your original aircraft.
Progress
I have no axe to grind with the C130 J but I'm happy to remain on the C130 Klassic...now being quietly and modestly refered to as
'THE LONG TERM FLEET'
