I think that at the moment the Part 145 orgs have two major concerns.
1)Implementing the MIP would reduce revenue by 80%
2)The maintenance procedure structure probably requires new documentation ,and accreditations which cost time and money.
In view of the overcommittment of most Part 145 orgs. they could perform annuals in a fraction of the time it takes for LAMP and leave competent pilot/owners to do 50hr etc.
This would help reduce the workload to a sustainable level, but increase revenue due to increased throughput.
Oversight or releases of permitted work not being required they are relieved of responsibility for the p/o work,and worries signing off work they have little control over.
