Part 121 · Reliability & reporting
Predictive maintenance
Each tail gets a 0–100 aircraft-on-ground risk score that surfaces which aircraft to look at first, and every score is shown with the factors that contributed to it — airworthiness posture, inspection timing, utilization, and age. It is deterministic and explainable, not a black-box prediction: you see what drove the number, not a mystery output. It replaces guessing which tail is the next surprise AOG.

Who it's for
Maintenance controllers at a Part 121 operation who want a ranked, traceable starting point for which tail to look at first, rather than guessing which aircraft is the next surprise AOG.
What it replaces
Guessing by hand which tail is the next surprise aircraft-on-ground.
What predictive maintenance gives you
- A 0–100 AOG-risk score per tail
- Shown with its factors: airworthiness, inspection timing, utilization, age
- Deterministic and explainable — not a black-box prediction
A 0–100 AOG-risk score per tail
Each tail gets a 0–100 aircraft-on-ground risk score that surfaces which aircraft to look at first, computed from its airworthiness posture, inspection timing, utilization, and age. Maintenance works the highest-risk tails first off a ranked list instead of a guess.
- A 0–100 AOG-risk score per tail
- Shown with its factors: airworthiness, inspection timing, utilization, age
Deterministic and explainable, shown with its factors
Every score is shown alongside the factors that produced it, and the same inputs always produce the same score — it is deterministic and explainable, not a black-box prediction. You see what drove the number rather than a mystery output, so a maintenance controller can trace the ranking back to the tail's airworthiness, inspection timing, utilization, and age.

How an operator uses this
Each tail gets a 0–100 aircraft-on-ground risk score that surfaces which aircraft to look at first, and every score is shown alongside the factors that produced it — airworthiness posture, inspection timing, utilization, and age. It is deterministic and explainable, not a black-box prediction: the same inputs always produce the same score, and you see what drove the number rather than a mystery output. It replaces guessing which tail is the next surprise AOG by giving maintenance a ranked, traceable starting point.

How it works
Predictive maintenance, step by step
Each tail's airworthiness posture, inspection timing, utilization, and age feed its score.
The system computes a 0–100 AOG-risk score per tail.
Open a score to see the contributing factors behind it.
Work the highest-risk tails first — the ranking is deterministic, not a prediction.
Questions
Predictive maintenance — frequently asked
Is the predictive-maintenance score an AI prediction?
No. It is a deterministic, explainable 0–100 score computed from tracked inputs — airworthiness posture, inspection timing, utilization, and age — and every score is shown with the factors that drove it. There is no black-box prediction model.
What does the AOG-risk score tell me?
Which tail to look at first. Each aircraft gets a 0–100 score from its airworthiness, inspection timing, utilization, and age, so maintenance has a ranked, traceable starting point instead of a guess.
