Fatigue
Gentler than its type
How short were its legs?
Utilization isn’t graded for B-129Z: 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.
More hours for each landing, so fewer pressurization cycles for its time in the air.
