N523JM · Gulfstream GIV flight activity
43 tracked flights in the 12 months to 31 Jul 2026, on about 3 days a month and an estimated 76 hours in the air.
How N523JM has been flying
Tracked by ADS-B, so a minimum.
From time in the air. The logbook has the exact total.
In the months it flew.
Last tracked in June 2026. Published seven days later, by month only.
Month by month
43 flights over 11 active monthsFlights per month
Its busiest month was October 2025, with 8 flights.
Its busiest month was October 2025, with 8 flights. It did not fly in July 2026. The record has 28 tracking gaps, so about one flight in 2 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 N523JM: 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.
Legs like most of the type. Typical on fatigue.
It lands about as often for its hours as most of the fleet, so cycles have built up at a normal pace.
Against 2.0 : 1 for the middle GIV (29th). Close to the type.

The data behind it
Against all 620 tracked GIVs, over its record since 1 Jan 2025.How it travels
One corridor carries a large share of its flights.
17 of 43 flights, both directions.
Most of its flying on three routes.
3 flights crossed a border.
One route carries a large share of N523JM’s flying: 40% of flights are on its most-flown pair of airports. Its top three pairs make up 56%, so about four flights in ten go somewhere else. Of its 43 tracked flights, 3 (7%) 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.
N523JM 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 →

About N523JM
How many hours does N523JM fly a year?
About 76 estimated hours in the 12 months to 31 Jul 2026, across 43 tracked flights. Hours are estimated from time in the air, so the logbook has the exact figure.

3 of its 43 tracked flights in the 12 months to 31 Jul 2026, 7%, crossed a border.
When did N523JM last fly?
It was last tracked in June 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 N523JM 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 N523JM?
All four graded chapters (Fatigue, Corrosion, Engines and brakes, and Utilization), each against the tracked GIVs, 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 N523JM’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 GIVs 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.
