But yes I hear what you are saying that you do not want to degrade the significance of the check lest you end up needing a dupe on a seat cushion change....
Yes, but a check list doesn't exist in a vacuum, it exists for a real-world purpose.
Changing how the cowlings are checked in response to a known, ongoing problem with certain aircraft/engine combinations would lead to an overall improvement in safety.
Surely that outweighs any 'degrading of significance' of the check?
surely it is enough that a licensed type rated engineer should reasonably be expected to carry out this task without the need for duplicates?
But recent events show that this isn't happening.
