The free chapter.

Each measure against all 94 tracked G150s. Every dot is one aircraft; the gold one is N9MM.

Chapter 1

Fatigue

Gentler than its type

How short were its legs?

Utilization isn’t graded for N9MM: 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.

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.

What only the report shows.

The fleet is shown, and whether N9MM sits inside its middle half. Its grades and values are in the full report.

Corrosion

Salt air, middle G150: 1%

Also graded: damp air, freeze–thaw, near the coast and moisture in the air.

Not graded: not enough data.
