Does the CASE standard cover all the elements of CFR 145? I'm setting up an internal audit schedule to cover 145 and I'm using CASE as the base-line but I'm not sure if CASE covers all of 145.
The CASE standard 1-A states that it is intended as a Supplement to the CFRs 145 and should be used in conjunction with them. Personally I use elements of it for my internal audits but have seen many auditors use the standard as the basis of their audit.
If you are using them as a guide for your internal auditing then you should be complying with all the applicable 145 regulations.
But now, I am curious also and will have to do a little more in-depth research myself.
