N450BC · Bombardier Learjet 45 flight activity
149 tracked flights in the 12 months to 31 Jul 2026, on about 8 days a month and an estimated 247 hours in the air.
How N450BC has been flying
N450BC flies about as often as the middle Learjet 45, inside the 4 to 10 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 4.4 d for the middle Learjet 45.
Last tracked in June 2026. Published seven days later, by month only.
Month by month
149 flights over 11 active monthsFlights per month · shaded band is the middle half of the fleet (3.8–9.8 a month)
N450BC flew more than the middle half of the fleet in 7 of 12 months. Its busiest month was August 2025, with 28 flights.
Its busiest month was August 2025, with 28 flights. It did not fly in July 2026. The record has 65 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 6.3 for the middle Learjet 45 (64th). Used like a typical Bombardier Learjet 45.

The data behind it
Against all 480 tracked Learjet 45s, over its record since 1 Jan 2025.How it travels
One corridor carries a large share of its flights.
45 of 149 flights, both directions.
Most of its flying on three routes.
6 flights crossed a border.
One route carries a large share of N450BC’s flying: 30% of flights are on its most-flown pair of airports. Its top three pairs make up 50%, so about five flights in ten go somewhere else. Of its 149 tracked flights, 6 (5%) 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
Outside the middle of the fleetWhere 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.

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 N450BC 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 N450BC?
All four graded chapters (Fatigue, Corrosion, Engines and brakes, and Utilization), each against the tracked Learjet 45s, 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 N450BC’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 Learjet 45s 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.
