Just a matter of fact.
When two components of the same type are changed on a larger type rpt aircraft they are not done by the same people. One team/person dose one side and the other is done by the other/team.
This is not done generally in GA.
Mainly because in GA your not working in a shift and you stay with the aircraft till it's finished.
And by the way there are lots of components that are date time limited.
But I do find it very strange that it's your bums and your families bums in the seats. One would think you would all wish before the best for your aircraft. I'm constantly amazed by owners of their complete lack of self preservation.
