N501S · Cessna Citation Mustang flight activity
88 tracked flights in the 12 months to 31 Jul 2026, on about 5 days a month and an estimated 101 hours in the air.
How N501S has been flying
N501S flies about two times as often as the middle Citation Mustang, inside the 3 to 7 flights a month flown by the middle half of the fleet.
Tracked by ADS-B, so a minimum.
From time in the air. The logbook has the exact total.
Against 2.8 d for the middle Citation Mustang.
Last tracked in July 2026. Published seven days later, by month only.
Month by month
88 flights over 12 active monthsFlights per month · shaded band is the middle half of the fleet (2.7–7.1 a month)
N501S flew more than the middle half of the fleet in 5 of 12 months. Its busiest month was April 2026, with 18 flights.
Its busiest month was April 2026, with 18 flights, and its quietest February 2026, with 1. The record has 42 tracking gaps, so about one flight in 2 may be missing and every count is a minimum.
Utilization
How steadily it has been used: flights, flying days and estimated hours against the type.
Used about as much as most. Typical on utilization.
Used at about the rate of most of the fleet, so its maintenance intervals have been used up at a normal pace.
Against 3.8 for the middle Citation Mustang (73rd). Used like a typical Cessna Citation Mustang.

The data behind it
Against all 327 tracked Citation Mustangs, over its record since 1 Jan 2025.How it travels
Its flying is spread across many routes.
16 of 88 flights, both directions.
Spread across many destinations.
0 flights crossed a border.
N501S’s flying is spread across many routes. Its most-flown pair of airports carries 18% of flights, 16 of 88, counting both directions. Its top three pairs make up 45%, so about six flights in ten go somewhere else. None of its tracked flights 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
Not graded: not enough dataWhere 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.
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.
N501S is in here
Also graded: hot, high takeoffs; density altitude; dust and dry climate. See this chapter in the sample report →

Why don’t you show which airports N501S uses?
We leave out airports, bases and exact dates on purpose. We show how an aircraft has been used, not where it goes.
What’s in the full TailCheck report for N501S?

How this page is made
Everything here comes from N501S’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 Citation Mustangs 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.
