WinAir runs the hangar. FileFlo proves the records.
WinAir is a deep aviation maintenance & engineering system: it forecasts and plans maintenance, runs work orders and production, and controls parts, purchasing, and MRO costs. FileFlo does a different job: it reads the Google Drive, SharePoint, or OneDrive your whole operation already uses, maps every compliance document to its CFR section, tracks every regulatory expiration, flags what's missing, and ships the inspector's binder in one click, across pilot files, training, the drug & alcohol program, OpSpecs, insurance, and leases, not just maintenance. Keep WinAir for the maintenance org; add FileFlo to prove the whole operation is audit-ready.

Maintenance management is not compliance.
WinAir: the M&E system
An established aviation maintenance & engineering platform for airlines, MROs, and CAMOs: maintenance forecasting and planning, work orders and production, parts and inventory control, purchasing, and cost accounting, plus maintenance compliance tracking. Deep and purpose-built for the maintenance organization. But it runs maintenance and inventory; it doesn't prove the pilot, training, drug & alcohol, OpSpecs, and insurance documents an FAA audit also demands.
FileFlo: the compliance proof
Built for one job: proving the whole operation's compliance documents are audit-ready. It reads the storage you already have, classifies each file to its CFR section across all 600+ document types, tracks every expiration, flags what's missing, and exports the inspector's binder. No migration, no maintenance-data integration, no per-seat tax. It does not replace the maintenance system, the SMS, or dispatch/FOS.
An honest split.
WinAir owns aviation maintenance, parts, purchasing, and MRO cost accounting. FileFlo owns compliance proof across every document type, without a migration.

What an M&E system doesn't cover.
CFR-cited classification
Every document mapped to its exact regulatory citation (the language an FAA, FMCSA, OSHA, or EPA inspector uses) across pilot files, training, drug & alcohol, OpSpecs, insurance, and leases, not just maintenance records.
Regulatory expiration alerts
Medicals, competency checks, recurrent training, certificates of insurance, and permits, all tracked to the regulatory interval and surfaced at 90/60/30/7 days, automatically.
One-click audit binder
Inspector-format, indexed binder generated in 60 seconds from the files already in your storage: no folder-diving, no export project, no separate maintenance pull.
Live the same afternoon
No migration, no maintenance-data integration project. Connect read-only and get a baseline gap report within 24 hours.
No migration means no IT project.
A maintenance system earns its keep on the shop floor, but standing one up, or wiring its data into anything else, is a real integration lift. FileFlo adds no such project: it reads the cloud storage your team already runs, classifies the compliance documents in place, and never touches your maintenance data.
Platform definition.
WinAir is an aviation maintenance & engineering (M&E) management platform used by airlines, MROs, and CAMOs. Its modules cover maintenance forecasting and planning, work orders and production, parts and inventory control, purchasing, cost accounting and invoicing, and maintenance compliance tracking; historically desktop/on-premises, it now offers a browser-based deployment. Its job is to keep aircraft airworthy and the maintenance organization running. FileFlo is not an M&E, MRO, inventory, or maintenance-tracking system. It is a compliance document intelligence layer that connects read-only to the cloud storage an organization already uses (Google Drive, SharePoint, OneDrive, or Dropbox) and classifies each file against its governing regulation (FAA 14 CFR Part 135, FMCSA 49 CFR, OSHA 29 CFR, EPA 40 CFR, and state programs) across more than 600 document types.
The two are not the same product category, and neither replaces the other. WinAir answers "what maintenance is due, what parts do we need, and how do we plan, perform, and cost the work?" FileFlo answers "which regulation does each document satisfy, what is expiring, what is missing, and how do we hand an inspector the right binder for the whole operation?" An FAA audit spans far more than the maintenance shop (pilot currency and medicals, recurrent and ground training, the drug & alcohol program, operations specifications, insurance, and aircraft leases), and that breadth is exactly the surface FileFlo proves on top of existing storage, with no migration, in an afternoon.
Why the maintenance system can't prove the whole audit.
For a Part 135 operator, an FAA inspection reaches across the entire operation, not just maintenance. Pilots must hold current medical certificates and meet recurrent-training and competency-check currency under 14 CFR Part 135; the operator runs a drug & alcohol testing program under 14 CFR Part 120; operations are bounded by the operations specifications issued under 14 CFR Part 119; and the maintenance records themselves live under Part 135's recordkeeping rules. A maintenance & engineering system manages and documents the maintenance side superbly (due-lists, task cards, component times, parts), but it does not interpret a pilot's medical expiry, a missing recurrent-training record, an OpSpec amendment, or an expiring certificate of insurance, because those documents live outside the maintenance domain.
That is the gap FileFlo fills. Rather than asking a maintenance system to cover documents it was never built for (or assembling audit evidence by hand from scattered folders), FileFlo leaves the storage exactly where it is and adds the regulatory layer across every document type: CFR-cited classification, 90/60/30/7-day expiration tracking, required-document gap detection per regulator, and inspector-format binder export. It does not replace the maintenance system, the Safety Management System, or dispatch/FOS; it proves the records are current and producible. (Note: the FAA's 2024 SMS final rule extends Safety Management System requirements to all Part 135 operators with a single compliance deadline of May 28, 2027; the SMS itself is a separate program FileFlo does not provide, though FileFlo can keep its supporting records audit-ready.)
For operators already running WinAir, the two coexist cleanly: keep WinAir as the maintenance & engineering system of record, and add FileFlo as the compliance-proof layer over the day-to-day cloud storage your team actually uses. WinAir keeps the aircraft airworthy; FileFlo proves the whole operation's compliance documents are audit-ready.
Built by an operator, against the rules themselves.
Chad Griffith, Founder & CEO of FileFlo, built FileFlo's rule packs against the actual inspector, surveyor, and safety-investigator protocols, not against a generic "compliance" abstraction. That regulatory specificity is exactly what a maintenance & engineering system isn't built to deliver across pilot, training, and operations documents, and why FileFlo can prove audit-readiness on top of the storage a team already has, without a migration project, alongside the WinAir you keep for maintenance.
Quick answers.
Last reviewed June 15, 2026.
Is FileFlo a replacement for WinAir?
No, and they're built for different jobs. WinAir is an aviation maintenance & engineering (M&E) system: it runs maintenance forecasting and planning, work orders and production, parts and inventory control, purchasing, and cost accounting for the maintenance organization. FileFlo is not an M&E, MRO, or inventory system and never tries to be. FileFlo is the compliance records-proof layer that reads the cloud storage your whole operation already uses and proves every compliance document is audit-ready: pilot and crew files, training, the drug & alcohol program, OpSpecs, insurance, and lease documents, in addition to maintenance records. Most operators keep WinAir for M&E and add FileFlo for compliance proof. They coexist.
We already run WinAir for maintenance. What does FileFlo add?
WinAir keeps your aircraft airworthy: it forecasts, schedules, and documents maintenance and manages parts. But an FAA audit reaches far beyond the maintenance shop: pilot currency and medicals, recurrent and ground training, the drug & alcohol testing program, operations specifications, certificates of insurance, and aircraft lease paperwork all have to be current and producible. FileFlo connects read-only to the Google Drive, SharePoint, OneDrive, or Dropbox your team already uses, classifies each of those documents to its exact CFR section, tracks every regulatory expiration at 90/60/30/7 days, flags what's missing, and exports an inspector-format binder in one click. It proves the whole operation's compliance, not just the maintenance side WinAir already covers.
Does FileFlo track maintenance, parts, or work orders like WinAir?
No, and that's deliberate. FileFlo is not a maintenance-tracking, MRO, or inventory platform. It does one thing deeply: classify every compliance document to its CFR section, track regulatory expirations across every regulator, surface missing documents, and export inspector-format audit binders. If you need maintenance forecasting, work orders, parts and inventory control, purchasing, or MRO cost accounting, that's WinAir's lane. If you need to prove every compliance document across the operation is audit-ready, that's FileFlo's.
What does FileFlo cost compared to WinAir?
WinAir is quote-based: pricing depends on modules, fleet size, and deployment, and is not published. FileFlo is transparent: $89/mo Starter, $299/mo Professional, 5-day free trial, no setup fees, and no per-document or per-seat compliance penalty. Because there is no migration and no maintenance-data integration, the deployment cost is effectively the 60 seconds it takes to connect your existing storage.
Can I keep WinAir and still use FileFlo?
Yes, that is the intended setup. Keep WinAir as your maintenance & engineering system of record. FileFlo connects to the cloud storage your team uses day-to-day (Drive / SharePoint / OneDrive / Dropbox) and adds the compliance-monitoring and audit-binder layer across every document type: pilot, training, drug & alcohol, OpSpecs, insurance, leases, and the maintenance documents too. FileFlo does not replace the maintenance system, the SMS, or dispatch/FOS; it proves the records are audit-ready on top of the tools you already run.
