As it stands now even if you choose not to believe it you have to SB and life limited component's as per the M/M.
More and more shops are demanding this as they are forced to by CASA its not the shop its Casa and more importantly will be your insurance policy will be U/S if you don't but then you try and sue the shop but they have a signed letter stating your the owner and you didn't wont them done.
There is nothing wrong with sched 5. As ive said its a victim of its own success and now casa are bring it back into line it was fine when it was supported by the Aust ADs but now they gone or going.
So now you will have to run what the manufacturer wonted, you got away with it for how long now.
At the end of the day the shop insurance is also going to play a huge roll as it does now with on condition engines a lot of shop wont and cant release them. And an on condition engine MUST have its component o/h at there correct time as well as they are NOT on condition only the core of the engine is
Its time you all stepped up to the mark the time has come its not 1990 any more sorry
