A&C,
What AWN35 says is carry out the 'on condition' inspections every 100 hrs (50 hrs for crop dusters) iaw CAAIPs (Inspection Procedures).
In CAAIPs it says to do a compression check if only by pulling the prop through by hand and feeling the compression 'manually' - it goes on to say that an alternative method is to use a differential compression tester.
