Each measure against all 257 tracked CitationJets. Every dot is one aircraft; the gold one is N399AB.

Chapter 1

Fatigue

Harsher than its type

How short were its legs?

Utilization isn’t graded for N399AB: 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.

Short legs put more pressurization cycles on the structure for the same time in the air. Worth checking its cycle-based inspection limits before a pre-buy.
