Chapter 1
Fatigue
Typical for its type
How short were its legs?
Utilization isn’t graded for N517JM: too few of its flights were tracked to count its use fairly, in the full report too. So its free chapter here is Fatigue, which doesn’t depend on catching every flight.
It lands about as often for its hours as most of the fleet, so cycles have built up at a normal pace.
