Its busiest month was April 2026, with 9 flights. It did not fly in September 2025. The record has 36 tracking gaps, so about one flight in 1 may be missing and every count is a minimum.
Fatigue
What each landing and pressurization cycle costs the structure: landings per hour and short hops.
Utilization isn’t graded for N990TC: 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.
Long legs, fewer landings. Gentler on fatigue.
More hours for each landing, so fewer pressurization cycles for its time in the air.
Against 1.3 : 1 for the middle Citation SII (97th). More hours for each landing, so fewer cycles for its time.
The spread of its trip lengths, against the type.
The data behind it
Against all 353 tracked Citation SIIs, over its record since 1 Jan 2025.How it travels
Its flying is spread across many routes.
7 of 41 flights, both directions.
Spread across many destinations.
23 flights crossed a border.
N990TC’s flying is spread across many routes. Its most-flown pair of airports carries 17% of flights, 7 of 41, counting both directions. Its top three pairs make up 37%, so about six flights in ten go somewhere else. Of its 41 tracked flights, 23 (62%) crossed a border.
Corrosion, engines and brakes, and utilization
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
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.
N990TC is out here, on one side or the other
Also graded: hot, high takeoffs; density altitude; dust and dry climate. See this chapter in the sample report →
04 Utilization
Not graded: too few of its flights were trackedHow hard has it been used? Heavy use spends maintenance intervals faster; long spells parked bring their own wear. Both are worth knowing before a pre-buy.
Also graded: days flown a month and estimated hours a year. See this chapter in the sample report →

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 N990TC?

How this page is made
Everything here comes from N990TC’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 SIIs against the middle aircraft, the 50th percentile. Between the 25th and 75th it is typical; outside that band it is gentler or harsher. Fatigue 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.
