The free chapter.

Each measure against all 94 tracked G150s. Every dot is one aircraft; the gold one is XB-SPK.

Chapter 1

Fatigue

Harsher than its type

How short were its legs?

Utilization isn’t graded for XB-SPK: 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.

Harsher means harder on the aircraft than three quarters of G150s; typical is the middle half. Percentiles compare this aircraft with every tracked G150, over its record since 1 Jan 2025.
