TailCheck
27 continuous days on the ground, 6 Nov 2025 — 18× this aircraft's baseline. Pull the work order.
Tempo down 6%/mo since the Sep-25 peak. Ask why before you offer.
Lower cycle intensity for the type — 34% short hops, a lighter mission profile.
The longest gap in the record — on the ground with no cause in the track.
It will be explained as scheduled maintenance. Ask for the work order number, not the explanation.
Recent tempo has eased off the record's own peak.
It will be explained as a schedule change. Ask whether the aircraft was listed before or after the slowdown started.
Measured against 493 active Gulfstream G650s
Top-decile utilization, sustained across the whole window - not a one-off spike.
See §02 · vs 90TH+
The longest continuous pause in the window - cause isn’t in the data.
The longest continuous pause in the window, at a field with MRO capacity. The gap is certain; the reason is not. A scheduled inspection and an unscheduled fix look identical from ADS-B - the work order and return-to-service settle it.
A legible rhythm over 18 months - one home base, no charter signature.
Nearly a quarter of its flights this window have run the exact same round trip, Dallas Love Field to Washington Dulles - pointing to consistent, single-operator use, not a charter shuffle.

Overall, this aircraft’s operating profile is broadly consistent with the Gulfstream G650 fleet. The material exception is the frequency and duration of its recent inactivity - see §05.
Against 493 active G650s, N555GA is a statistical outlier - top-decile flight tempo. The pattern is consistent, not erratic. Unusual operation, cleanly flown.
Bar length = how far this tail sits from the fleet median (centre) - the longer the bar, the bigger the deviation; left of centre is below the fleet, right is above. Colour reads cycle intensity only: green = lower cycle intensity, amber = verify, grey = operational exposure or mission profile (context, not a verdict). Percentiles run against 493 active G650s; shaded band = middle 50% of the fleet. From track = counted from ADS-B; Modeled = estimated from time airborne. Lifetime totals are left to the logs.
These are the closest-matching operating profiles among active peers - useful for sanity-checking whether this tail’s pattern is a fleet outlier or business-as-usual, not for pricing.
Similarity is scored on observed operation only - utilization, stage length, cycle quality, recency. Analogue tails are illustrative sample entries.
Nineteen months of activity against the tail’s own baseline. One month breaks the pattern - everything else is a steady rhythm that builds through 2025 and eases through 2026.
The read: three gaps to run down. Nothing here proves a defect - but it lets a pre-buy target specific windows instead of reconstructing 18 months blind. The same record works from either side of the table.
The longest continuous pause in the window, at a field with MRO capacity. The gap is certain; the reason is not. A scheduled inspection and an unscheduled fix look identical from ADS-B - the work order and return-to-service settle it.
This is the one item to run down first. Neutral on its own; the records decide whether it stays neutral.

The track reads operation, not condition or title. Everything below lives in the logs, the data room, or with your appraiser - hand this list to whoever runs the pre-buy. Naming it is the point: no flight-data product can substitute for it, and pretending otherwise is where competitors overclaim.
The full record - vs-fleet outlier analysis, the 27-day gap, and the recommended records request - unlocks with TailCheck.
