C'mon Dawg. You know better than that. Even if the crew in question had been pounded the entire week and fatigue was a HUGE factor, NTSB will never list it as primary probable cause.
Crew fatigue MIGHT be listed as a contributing factor along with a contaminated runway.
Absent a documented mechnical failure that we don't know about yet, the blame will be placed fully and squarely (unfortunately) on the flight crew.
The NTSB has always been reluctant to call out an operator on fatigue issues as major factors in an accident. The DC-8 at Gitmo and Colgan are the only two cases I can recall where fatigue was cited as MAJOR contributors to the accident and even then they tossed much of that responsibility on the crew, not the company.
Then again, hope springs eternal and maybe this time some of the focus will move toward scheduling practices at ALL fractional operators.
Regardless, I feel bad for the crew and I'm just thankful nobody got hurt.
