Know what the engine is worth.
Know what to do with it.
AEVA values a commercial jet engine the way the market does: by serial number, against what the type is trading for, with the range it sits in and the reasons it is where it is.

Hover or tap any candle for what moved the number. An example engine in a modeled market: the published values, listings, lease rates and shop backlogs on file for the type, with demand against supply carried between readings. The projection runs the engine forward at typical utilization with today's market held. Your engine runs on its own records and the live market.
- Every life-limited part is priced at the manufacturer's current list price.
- Listings, lease rates and published values are collected and dated every day.
- Shop turnaround and green time are counted in the value.
- Built by people who have traded engines for thirty years.
Every engine, not a short list
98 engine families across airliners, regional and business jets, turboprops and helicopters. Pick the type and start with the serial number.
From a serial number to a number you can defend
Three screens. The first two are yours; the third is the value, with everything that set it.
1
Tell us the engine
Family, thrust rating, serial, cycles and hours since new, hours since the last shop visit, and where it sits. If you only know the cycles, start there.
2
Grade its condition
Pick a grade, or answer seventeen plain questions about life remaining, modules, compliance and records. The guided version takes three minutes and narrows the range.
3
Read the number
The market value, the range it trades in, what set it and what moved it, the material floor underneath, and the best play ranked against the other five.
Built the way a trader values an engine
Five stages, in order, every time. Each one is a line on the result, with its date.
Stage 1
Material floor
Every life-limited part priced from the manufacturer's current list price and prorated by the life left in it, plus the green time still on the engine.
Stage 2
Market base
What the family trades at today, from published half-life values and the asking prices of comparable engines on the market.
Stage 3
This engine
Where your serial sits against half life, and the premium or discount that earns it.
Stage 4
Condition and market
Condition, records, region, open directives, and how much supply is chasing how much demand.
Stage 5
The range
The band the engine trades in, and the one input that would narrow it most.
Market saturation
How many engines of the type are for sale or lease, what they ask, how long they sit, and how that balance has moved. Supply against demand, read as a number.
Part-out value
Every part in the engine carries a price. The life-limited stack is prorated by the cycles left in each disc, spool and shaft, so the floor under the engine is never a guess.
Shop economics
Shop turnaround, slot waits, restoration cost and the green time still on the engine. When the next visit falls, what it costs, and what the engine is worth before and after.
Thirty years of trading
The formula is built the way an engine trader values an engine, calibrated against real transactions by people who have bought, leased and parted out these engines for three decades.
