Wyvern audits it. FileFlo keeps it ready.
This isn't FileFlo versus Wyvern. Wyvern audits and rates Part 135 operators against the Wingman and PASS standards. FileFlo manages the pilot records, maintenance documents, and SMS materials the Wyvern audit examines, and keeps them current year-round. Keep the rating. Add the document layer.

Different categories, often paired.
This is the cleanest way to think about it: Wyvern is an audit + rating service. FileFlo is software. The decision isn't either-or. Most Part 135 operators benefit from both.
You need Wyvern when you...
- ·Want an industry-recognized safety rating (Wingman or PASS)
- ·Need to compete for charter business where brokers require ratings
- ·Carry celebrity / executive passengers who require rated operators
- ·Want third-party validation of your safety program
- ·Have an insurance discount tied to safety rating maintenance
You need FileFlo when you...
- ·Want organized pilot records (135.293/.297/.299) day-to-day
- ·Need aircraft maintenance + airworthiness document tracking
- ·Want automatic currency alerts (90/60/30/7-day)
- ·Are prepping for a Wyvern audit and want one source of truth
- ·Have multi-regulation exposure (Part 135 + ground OSHA + FBO EPA)
- ·Want flat $89-$299/month software billing, not audit fees
Fourteen capabilities, side by side.

Platform definition.
FileFlo is a compliance document intelligence platform for aviation operators. For a Part 135 certificate holder it operates as a read-only system of record over pilot files, aircraft maintenance documents, training certifications, drug-and-alcohol program records, and Safety Management System materials, classifying each document against its governing section of FAA 14 CFR Part 135, extracting expiration and currency dates, and producing an inspector-format audit binder on demand. It does not perform audits, issue certifications, or assign safety ratings.
Wyvern Ltd is a different category: an independent third-party aviation safety auditor and rating company. Wyvern evaluates a Part 135 operator on-site against the Wingman or PASS standard and issues an industry-recognized safety rating that brokers and Part 91/K passengers use to select operators. The distinction matters because a rating is an external attestation produced by an independent auditor, while document management is an internal capability the operator runs continuously. FileFlo maintains the §135.293, §135.297, and §135.299 currency records and §135.21 manual files that a Wyvern audit examines, but the audit and rating issuance remain Wyvern's separate engagement.
Why a rating doesn't track your currency.
A safety rating is a point-in-time attestation; the underlying FAA recordkeeping obligation is continuous. Under 14 CFR Part 135, a certificate holder must keep each required pilot current across several distinct cycles: the §135.293 written and competency check (every 12 calendar months), the §135.297 instrument proficiency check (every 6 calendar months for crewmembers in IFR operations), and the §135.299 line check (every 12 calendar months). Each runs on its own calendar-month clock, and a lapse in any one removes the crewmember from the operation regardless of how recently the operator earned its Wingman or PASS rating. A Wyvern audit verifies these records on the day the auditor is on-site; it does not monitor them in the months between.
The same continuity gap applies to manuals and maintenance. Under §135.21, a certificate holder must prepare and keep current a manual for the use and guidance of flight, ground, and maintenance personnel, and ensure each affected employee has the current portions. On the maintenance side, the airworthiness records the operator must hold (the §43.9 maintenance record entries, the §91.417 owner/operator retention file, and the Part 39 Airworthiness Directive compliance documentation) are document evidence an FAA inspector or a Wyvern auditor can ask to see at any time. Storing them is not the same as knowing which are current, which are expiring, and which are missing.
This is the layer FileFlo fills. It classifies each pilot, maintenance, training, and SMS document to the CFR section it satisfies, monitors every currency and expiration at 90/60/30/7-day intervals, surfaces the required-document gaps before an auditor finds them, and assembles the Part 135 binder in the format the inspector expects. The result is that an operator walks into the Wyvern audit (and the FAA surveillance event) already current, rather than reconstructing the record set under deadline.
Built by an operator, against the rules themselves.
Chad Griffith, Founder & CEO of FileFlo, built FileFlo's rule packs against the actual surveyor, inspector, and safety-investigator protocols, not against a generic "compliance" abstraction. Each regulator's taxonomy maps documents to the exact CFR section that demands them, which is why FileFlo can sit underneath a rating body like Wyvern and still speak the language an auditor uses. Wyvern's Wingman and PASS ratings have been the industry standard for Part 135 safety differentiation for over three decades; FileFlo doesn't compete with that; it makes the underlying document set easier to maintain, so audit prep becomes a binder export instead of a fire drill.
Quick answers.
Last reviewed June 4, 2026.
Is FileFlo a Wyvern alternative?
No, and that's an important honest answer. Wyvern Ltd is an independent third-party safety auditor and rating company. They evaluate Part 135 charter operators on-site, against the Wingman or PASS standards, and issue an industry-recognized safety rating. Brokers and Part 91/K passengers use that rating to pick operators. FileFlo is documents-first compliance management software. We help you keep pilot records, maintenance logs, training certifications, and SMS documentation organized and audit-ready, including for a Wyvern audit. These are complementary, not substitutes.
Should I use FileFlo to prepare for a Wyvern audit?
Yes. That's exactly the kind of use case FileFlo fits. The Wyvern audit (Wingman or PASS) examines whether your pilot currency, training records, aircraft maintenance documentation, drug/alcohol program, and SMS manual are organized and current. Operators who walk into the audit with a disorganized document set get findings. FileFlo's expiration tracking, AI document classification, and audit binder export let you arrive prepared. We're not replacing Wyvern's auditor; we're making the audit easier and the operator look better.
Does FileFlo issue safety ratings like Wyvern's Wingman or PASS?
No. Safety ratings require independent third-party evaluation. Software can't issue a safety rating about itself. Wyvern, ARGUS (Gold/Platinum), and IS-BAO are the recognized rating frameworks. FileFlo helps you maintain the underlying documentation that makes you ratable, but the audit + rating is a separate engagement with Wyvern (or another approved auditor).
What does FileFlo cost vs Wyvern's program fees?
Different products, different cost structures, not directly comparable. Wyvern's program involves an annual membership plus the audit engagement fee (varies by operator size and audit scope; typically several thousand dollars). FileFlo is flat $89/month Starter or $299/month Professional, a software subscription, not certification. Many Part 135 operators carry both: Wyvern for the rating, FileFlo for the underlying compliance management.
Is FileFlo aviation-specialized like Wyvern?
FileFlo's aviation rule pack covers Part 135 (commuter and on-demand operations), Part 91 (general operation), Part 43 (maintenance), training, drug/alcohol, and SMS documentation. Wyvern is purely aviation-focused. The trade-off: Wyvern goes deeper on the audit dimension (their core product); FileFlo goes broader on the operations dimension (you can run Part 135 + ground transportation OSHA + your hangar's EPA hazwaste in one tenant).
Can FileFlo help me get a Wyvern Wingman or PASS rating?
Indirectly, yes. Getting a Wyvern rating requires meeting their audit standard. FileFlo helps by keeping the document set the audit examines clean, current, and exportable. We track pilot recency (135.293, .297, .299), aircraft maintenance status (Part 43 / 91.409 inspections), training records, and SMS program documentation. When the Wyvern auditor arrives, you can produce any document on request without scrambling. The rating decision itself is Wyvern's.
