"Replaced IAW Cessna 402 AMM PN; 12334-54545 Rev4 ATA chapter 33-50-00."
Is incorrect unless stated in company procedures manual.
"Manuals are another huge annual cost in CAR30 and 145 .With auditors wanting to see your subscriptions. Companies like ATP love it."
CASA too if you run a mixed fleet look at $20K+ annually.
"Plus any test equipment you use...."
Yes traceable details in worksheets are required for each calibrated tool, again many $?,000 a year in calibration.
I think CAR 30 will be fine for current piston charter AMO,s but no new will pass & no current can keep CAR 30 and get Part 145 as well??
