Its busiest month was January 2026, with 4 flights.

Its busiest month was January 2026, with 4 flights. It did not fly in October 2025. The record has 13 tracking gaps, so about one flight in 1 may be missing and every count is a minimum.

Chapter 01

Fatigue

Typical than the type

What each landing and pressurization cycle costs the structure: landings per hour and short hops.

Utilization isn’t graded for XA-MLS: 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.

Hours per landingTypical
1.1 : 1

Against 1.2 : 1 for the middle BeechJet 400 (39th). Close to the type.

How it travels

One corridor carries most of its flights.

Most-flown pair
53%

9 of 17 flights, both directions.

Top three pairs
71%

Most of its flying on three routes.

International
12%

2 flights crossed a border.

Most of XA-MLS’s flying is on one route: its most-flown pair of airports carries 53% of flights. Its top three pairs make up 71%, so about three flights in ten go somewhere else. Of its 17 tracked flights, 2 (12%) crossed a border.

Chapters 02–04

Corrosion, engines and brakes, and utilization

02 Corrosion

Not graded: not enough data

Where 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.

Salt air Lead metric
Nights within 2 km of the coast, as a share of nights we can place
middle BeechJet 400 1%
In the report

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

Not graded: not enough data

How 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.

Short runways Lead metric
Departures where the longest runway was under 1.25× the takeoff distance
In the report

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 tracked

How 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.

Flights a month Lead metric

When did XA-MLS last fly?

It was last tracked in April 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 XA-MLS 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 XA-MLS?

All four graded chapters (Fatigue, Corrosion, Engines and brakes, and Utilization), each against the tracked BeechJet 400s, 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.

Method

How this page is made

Everything here comes from XA-MLS’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 BeechJet 400s 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.
