You state prices as $ per Hour - it should be $ per Man-hour
Yes. I do contracts and we tend to get slack in our language - in our world it is taken as given that all labour rates are in man-hours. They are fully stated in black and white in the paperwork.
The question is why do you think that premium car companies have higher labour rates than aircraft MROs? Because their customers are able and willing to cough up rather than go without their precious Beemer for a few days, that's why. While I recognise the equivalent skill levels of the car mechanics, they do not carry the same responsibility levels as LAEs and its very discouraging to work in the current situation. Because airlines' customers now expect to fly halfway round the world for the price of a night out on the piss, the airlines don't have the cash to pay for maintenance. On the other hand, the regulations oblige them to have it done. So, they bargain maintenance rates down as low as they can go.
What is happening now is that MROs are running out of hangar slots and, with their customers having to outbid each other to get work done, are becoming able to resist the downward pressure on labour rates. Eventually MROs will also be in a position to outbid each other in their search for labour. The airlines will pass the increased cost on to passengers and the Shell Suit army will have to pay the proper fare for their journeys - even on LCCs. It won't happen overnight, and most of we old timers will be on our pensions before things really take off, but change is definitely on the way.
