Tracked by ADS-B, so a minimum.
From time in the air. The logbook has the exact total.
Against 3.9 d for the middle GV.
Last tracked in July 2026. Published seven days later, by month only.
Month by month
111 flights over 12 active monthsFlights per month · shaded band is the middle half of the fleet (3.5–7.3 a month)

Utilization
How steadily it has been used: flights, flying days and estimated hours against the type.
Flown far more than most. Harsher on utilization.
Heavy use means more of its maintenance intervals have been used up. Worth checking where it sits in its inspection cycle before a pre-buy.
Against 5.0 for the middle GV (79th). Used harder than most.

The data behind it
Against all 638 tracked GVs, over its record since 1 Jan 2025.How it travels
Its flying is spread across many routes.
6 of 111 flights, both directions.
Spread across many destinations.
19 flights crossed a border.
N136FX’s flying is spread across many routes. Its most-flown pair of airports carries 5% of flights, 6 of 111, counting both directions. Its top three pairs make up 15%, so about nine flights in ten go somewhere else. Of its 111 tracked flights, 19 (18%) crossed a border.
Fatigue, corrosion, engines and brakes
01 Fatigue
Close to the typeHow short were its legs? Airframes age by landings as well as by hours. Many short legs put more pressurization cycles on the structure for the same time in the air.

Also graded: short hops. Leg length is shown as context. See this chapter in the sample report →
02 Corrosion
Close to the typeWhere does it spend its nights? Where a jet sleeps shapes how fast it corrodes. Salt and damp overnight are what an inspector looks at first.
N136FX is in here
Also graded: damp air, freeze–thaw, near the coast and moisture in the air. See this chapter in the sample report →
03 Engines and brakes
Close to the typeHow hard were its airfields? Short, hot and high runways ask for more thrust on every takeoff and harder braking on every landing. That wear doesn’t show in the hours.
N136FX is in here
Also graded: hot, high takeoffs; density altitude; dust and dry climate. See this chapter in the sample report →

How this page is made
Everything here comes from N136FX’s ADS-B track, the position signal aircraft broadcast, over the 12 months to 31 Jul 2026. ADS-B misses some flights, so every count is a minimum. Flights appear seven days after they happen, by month only, and hours are estimated from time in the air; the logbook has the real totals. Airports, bases and exact dates are left out on purpose. How grades work: each graded measure is placed among the tracked GVs against the middle aircraft, the 50th percentile. Between the 25th and 75th it is typical; outside that band it is gentler or harsher. Utilization is graded here for free; for the other chapters this page shows the middle value of the fleet and whether this aircraft sits inside the middle half or outside it. Their grades and values are in the report, not on this page. Owners and operators can ask us not to publish an aircraft’s activity.
