N550AT · Bombardier Challenger 350 flight activity
59 tracked flights in the 12 months to 31 Jul 2026, on about 4 days a month and an estimated 71 hours in the air.
How N550AT has been flying
N550AT flies about half as often as the middle Challenger 300, inside the 5 to 23 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 5.8 d for the middle Challenger 300.
Last tracked in July 2026. Published seven days later, by month only.
Month by month
59 flights over 11 active monthsFlights per month · shaded band is the middle half of the fleet (5.0–23.1 a month)
N550AT stayed within or below the middle half of the fleet in every month. Its busiest month was September 2025, with 9 flights.
Its busiest month was September 2025, with 9 flights. It did not fly in August 2025. The record has 24 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.
Flown less than most. Gentler on utilization.
Light use spends maintenance intervals slowly, but long spells parked bring their own wear: seals, corrosion and preservation. Worth asking how it was stored.
Against 8.4 for the middle Challenger 300 (23rd). Used more lightly than most.

The data behind it
Against all 836 tracked Challenger 300s, over its record since 1 Jan 2025.How it travels
Its flying is spread across many routes.
11 of 59 flights, both directions.
Spread across many destinations.
2 flights crossed a border.
N550AT’s flying is spread across many routes. Its most-flown pair of airports carries 19% of flights, 11 of 59, counting both directions. Its top three pairs make up 34%, so about seven flights in ten go somewhere else. Of its 59 tracked flights, 2 (3%) crossed a border.
Fatigue, corrosion, engines and brakes
01 Fatigue
Outside the middle of the fleetHow 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.
N550AT 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
Outside the middle of the fleetHow 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.

Also graded: hot, high takeoffs; density altitude; dust and dry climate. See this chapter in the sample report →

Does N550AT fly internationally?
2 of its 59 tracked flights in the 12 months to 31 Jul 2026, 3%, crossed a border.
When did N550AT last fly?
It was last tracked in July 2026. We publish an aircraft’s flights seven days after they happen, and show them by month only.
Why don’t you show which airports N550AT 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 N550AT?
All four graded chapters (Fatigue, Corrosion, Engines and brakes, and Utilization), each against the tracked Challenger 300s, plus the operational summary and operating rhythm, as a PDF, CSV and share link. It costs $395, or $995 a month for unlimited reports and Spotlight.
How this page is made
Everything here comes from N550AT’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 Challenger 300s 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.
