If a helicopter is fitted with an engine that is not certified for civilian use, is that something that would be picked-up when undergoing engineering work / issuing or re-issuing the C of A?
Does the aswer to my first question above also apply to other flight-critical components?
A very good question but I hope the answers cover carefully the suggested wording of;
should vs would.
In other words there are two parts of this issue
Are there clear regulatory words that cover this and where?
Are there standard practices that ensure this?
