In Piney Bobs post of Dec 27th he speaks of hard costs, he like many other forget about Overhead. It costs the company alot of money for these facilities, and that needs to be factored into the Hard Cost theat Bob speaks about. The problem is with a shrinking fleet you have less aircraft to spread those costs over on, thus the overhead cost per aircraft is more, driving up the cost per airplane, thus making keeping it in-house over outsourcing. Why do you think stsrt-ups outsource, it is to keep their overhead low. Unfortunatly all of the legacy carries are high overhead operations. Also, Overheadf is a FIXED COST, and business try to make costs variable, because they only have a cost when a service is required. One of my favorite quotes on high fixed costs of an airline is from Richard Branson. If you can lease it over buying it; leaee it, if you can rent it over leasing it; rent it, if you can borrow it over renting it borrow it. Therefore when the airlines are sheading these MTC facilities they are reducing their fixed expense, thus lowering their break even point.
I would give an example on one of the speciality shops. One of my "favoriate" the coffe pot shop. For example it costs $900.00 to repair an average coffee pot, and it takes one person one day to complete the repair. And there are 250 coffee pots per year to repair. At that point everbody is happy sine the shop is being fully utilized, and the shop is keeping up with the work. If you take the textbook costing of a service business 33% of the cost is labor ($300.00) 33% for parts ($300.00) and 33% for overhead ($300.00)
Now the airline has shrunk, and there are only 125 coffee pots to repair (50% of capicity) the cost of the repair will go up. You now have the same overhead to spread over fewer coffee pots so the the overhead is now $600.00 per coffee pot, you still have the same tech, and union contract states he can't do anything else, and he needs 40 hour per week so labor cost is $600.00 per coffee pot, the parts remain the same $300.00, so the total cost now is $1,500.00.
So when out sourcing costs $1,200.00 it is a deal for today's airline, but more expensive than in past years keeping it in-house.
So, the company choose to out-source. One other opition is what Air Canada did; improve the productivity of their shops to be competitive, and sell the excess capicity to other airlines so that the fixed costs are absorbed by maximum amout of repair possible.
Bob is also very correct about Supply Chain costs, and the cost of Inventory of spares. But that accounting 101 is for another day.
So if I follow Bob's post about ways to bring work back in-house, It is not only labor dollars, work rules that need to be looked at, how the company manages repairs, and controls the overhead if they are to be sucessful at utilizing the facilities at 90% plus of capicaty.
