That's how we did it for maintenance on our helicopters in my unit. Got tired of finding issues on startup or in flight and decided we needed something new. Not that they were bad folks, but low and behold repairs became much more complete.. . . and I like having the mechanic that just did the work having to take it for a test ride. It pretty much forces them to bet their lives on their ability to do their job right.
That's QC right there.
