So it means that if you removed component from engine in serviceble condition you update only missing parts list/ open item lists and "old" EASA Form one was still valid?
And what in case of installation of components on off-wing engine did you issued EASA Form one for the engine or also EASA Form one was still valid?
We are in the situation that the Operator requests to sent the engine with removed component to diffrent organisation that is why I am wondering is it allowed to certify the removal of the parts on EASA Form 1.
