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.
An airworthiness directive commonly known as an AD is a mandatory instruction that must be carried out when it is applicable to your aircraft within a given time frame.
The airworthiness directive for example might be repetitive in nature, it might have an option to terminate the requirement by performing a modification or it might be a one-off task. One query you might have to address is the embodiment or accomplishment date for a given AD and this can be very important, especially when considering any instructions for continued airworthiness
(ICA).
In the prior post we looked at why the engine might go for a shop visit and now we will consider
some of the areas you would typically consider.
After the work is completed, you will have a work pack that is a record of all the work carried out
and also the engine current status which might include such documents as the following:
