Minimum Equipment List (MEL) for non-revenue flights
I was reading about the Delta aircraft that made an emergency landing in Midway Atoll due to a cracked windshield. I suppose replacing the flt.deck window is not an "easy" job to do at a remote unequipped airfield.
Of course, this probably is not on the MEL. Question is, are there items not on the MEL that are ok to fly without if not doing a revenue flight. i.e. Are there some repairs for which it is ok for a maintenance crew to re-position the airplane to a better field. I suppose the regulations must be OK allowing a higher risk for non-passenger flights?
Curious if there is a similar non-revenue MEL.
