APU Evaluation

Indicative GO / CAUTION / NO-GO trade verdict

Enter the APU's identity, utilisation, shop-visit history and LLP status, plus records and market notes, and get an indicative trading verdict with a risk rating and technical / records / market subscores. APU cycles are starts — counted separately from APU hours. Nothing you enter is stored beyond the computed result, retained anonymised for quality review.

Have the documents as PDFs? Upload an APU mini-pack, LLP status sheet, shop-visit report or AD/SB status → for a data-pack preview — identity/utilisation figures and the records checklist, each with a confidence score, plus the LLP stack and shop-visit history extracted row by row instead of typed below. We check it's APU material before processing, and never store the file.

Step 01

Identity

APU serial, model and current operator/lessor.

APU serial

APU model

On / off-wing

Current operator

Lessor / owner

Host aircraft registration

Step 02

Utilisation

Total and since-last-shop-visit hours and cycles — APU cycles are starts, distinct from hours.

AHSN (APU hours)

ACSN (APU cycles / starts)

Avg hours per cycle

Hours since last SV

Cycles since last SV

Cycles to next planned SV (optional)

Step 03

Shop visits

One row per shop visit — APU maintenance is on-condition, so describe the workscope in your own words.

Date	Facility	Workscope	AHSN/ACSN

Step 04

LLP stack

One row per life-limited part (impellers, turbine disks) — lives in APU cycles. A part's own cycles may exceed this APU's ACSN (back-to-birth across hosts). Some APU types (e.g. GTCP36-300, GTCP331-350) have no LLPs at all — leave this empty if so.
