How airlines manage
shop visits today.

Spreadsheets per shop visit
One Excel per SV. Shared over email. Always out of date by the time someone reads it.
Decisions buried in email threads
A €50,000 finding approval buried in a reply chain from three months ago. Good luck finding it.
No delay classification
Engine late. Nobody can prove which days are excusable and which aren't.
KPIs assembled manually
TAT, cost variance, performance — manually compiled every quarter from five spreadsheets. Always wrong.

OLEN makes it
structured by default.

One source of truth
Every workscope, finding, approval, and document lives in OLEN. No email, no spreadsheet, no ambiguity.
Delays classified automatically
Every delay logged, categorized as excusable or not, and attributed to the responsible party — in real time.
KPIs calculated, not compiled
Your portfolio dashboard updates live. Management always has the real numbers. No manual work.

Everything a shop visit needs.
Nothing it doesn't.

Four modules covering the full lifecycle — from induction to financial closure.

Workscope Control
Structured L1/L2/L3 workscopes with findings, cost approvals, and real-time status tracking. Every task and decision is recorded, attributed, and auditable.
L1/L2/L3 ScopeApproval WorkflowFindings LogCost Tracking
Timeline & Delay Tracking
Full induction-to-delivery timeline. Excusable vs non-excusable delay classification built in.

Document Repository
All SV documents centralized, versioned, and auditable. Workscopes, findings reports, invoices, 8130s — one place, always accessible. Zero email attachments.

Portfolio Dashboard
Aggregate KPIs across MROs, customers, engine types, and fleet. On-time delivery rates, TAT benchmarks, cost variances — export-ready reports for leadership on demand.

Know exactly
what caused the delay.

Every day of delay is logged, classified as excusable or non-excusable, and attributed to the responsible party. Both airline and MRO see the same data.

  • Committed induction and delivery dates set at shop visit creation. No ambiguity.
  • Delay events logged in real time by the MRO, with reason codes and classification.
  • Automatic accountability scoring — MRO-caused vs airline-caused, calculated live.

Every document.
Always findable.

No more email attachments. No more "can you resend the latest version." All SV documents live in OLEN, versioned and immediately accessible.

  • Automatic versioning — every update tracked. No more "Final_v8_FINAL2.pdf".
  • Linked to findings and approvals — documents are contextual, not just stored in a folder.
  • Full audit trail — who uploaded what, when, and whether it was reviewed and approved.

From induction to closure.
In three steps.

A clear, structured workflow that both airlines and MROs follow inside OLEN.

01
Airline opens the Shop Visit
The airline creates the SV in OLEN — defining scope, assigning the MRO, and locking in dates.
  • ESN, engine model, CSN, first limiter
  • Workscope definition
  • MRO assignment
  • Return conditions
02
MRO executes in real time
The MRO logs findings, requests approvals, uploads documents, and records delays — all in OLEN.
  • Findings with disposition and cost
  • Approval requests to airline in-platform
  • Delay events with reason classification
  • Document upload with versioning
03
Shop Visit closes with full record
On delivery, the airline closes the SV. Every decision, cost, delay, and document is locked permanently.
  • Financial closure and cost reconciliation
  • TAT vs commitment analysis
  • KPI score captured automatically
  • Historical record

One platform.
Three stakeholders. Zero misalignment.

Operators
Own every shop visit.
Know exactly where every engine is, what's being done to it, who approved what, and why it's late — without picking up the phone.
  • Full workscope visibility from day one
  • Real-time approval workflow
  • Delay classification and accountability
  • Portfolio KPIs always live
MROs
Serve clients better.
A professional, structured interface for your airline clients. Log findings, request approvals, justify delays, upload documents — all in one place.
  • Structured findings and disposition log
  • In-platform approval requests
  • Transparent delay justification
  • Competitive differentiation through clarity
Lessors Coming Soon
Monitor your portfolio.
Read-only observer access to track the condition and SV history of every engine in your portfolio — across all operators and MROs.
  • Portfolio-wide engine health view
  • SV history per ESN
  • Return condition compliance tracking

Built from inside
a Powerplant team.

OLEN was designed in direct collaboration with powerplant directors and fleet operations leads at international airlines. The people who live this problem every day helped define every screen, every workflow, and every field.

Not a consultant's concept. A practitioner's tool.

Operator-designed workflows
Every feature mirrors how airlines actually manage shop visits. No invented UX, no consultant assumptions.
Confidential pilot program
Validated in a live airline environment. Real engines, real MROs, real shop visits — not a demo environment.
European aerospace pedigree
Founded in Madrid. Backed by NextGenerationEU innovation funding.
Enterprise-grade security
Role-based access control, GDPR compliant. Your data belongs to you.
