Critical maintenance before it grounds the aircraft
Performance-first warnings from engine trends, plus recurrence. Each item is ATA-chaptered so the hangar can schedule work — not read a vibe.
Performance first
Rising ITT, fuel-flow creep, and oil issues show up as critical predictions, not as a copy of the snag list. The fleet screen already shows ITT exceedances next to those predictions.
Something a hangar can schedule
Examples already on the product: ATA 72 hot-section borescope, ATA 73 fuel-nozzle inspection, engines inside 100 hours of HSI. Dates and remaining hours, not a chatbot paragraph.
What it is not
It is not an engineer. It does not auto-issue work orders. It does not claim coverage of every aircraft type — the landing product screen already shows PT6A and PW150 engines we monitor.
Is this just AI?
Trends and limits come first. Language on a prediction is secondary. If the slope is not there, we do not invent a warning.
What does critical mean?
Work that should be scheduled before the next utilization block — for example a hot-section borescope or a fuel-nozzle inspection — not a nice-to-have inspection.
Which engines?
The engines already on the AirVara fleet screen: PT6A and PW150. We do not list types we do not show.
