Last post we considered Airworthiness Directives (AD) and their embodiment date and noted this was the CRS (Certificate of Release to Service) date we would be using for this purpose.
We noted that some AD’s might be repetitive in nature; for example repeat an inspection every 500 flight cycles (1 cycle = a take-off and landing).
In the EASA system, the owner/CAMO is not required to keep the works orders or task cards commonly referred to as the dirty fingerprints (DFP)., i.e. the exact time of the performance of the maintenance which in our case is the AD action.
