No — an ARGUS rating, a Wyvern Wingman audit, or an IS-BAO registration does not satisfy the FAA Part 135 SMS rule. Those are private, voluntary third-party safety programs run by independent organizations; they are not FAA regulations and are not accepted in place of the rule. The 2024 FAA final rule requires qualifying Part 135 certificate holders to develop and implement a Safety Management System under 14 CFR Part 5 and to submit a Declaration of Compliance to the FAA under §5.9 by May 28, 2027. A third-party audit can support your SMS — much of the evidence overlaps — but it does not build your Part 5 SMS for you and it does not file the declaration. You still own both.
If you operate under Part 135, you are likely juggling two pressures at once: charter brokers and flight buyers want to see a recognized safety rating, and the FAA is about to require a fully implemented SMS. It is natural to ask whether one solves the other. This guide draws the line clearly — and shows why the smartest move is to keep one well-organized evidence library that serves both.
A Third-Party Rating and the FAA SMS Are Two Different Things
The confusion is understandable. A safety rating and an SMS both involve audits, both examine your safety practices, and both generate stacks of documentation. But they answer to entirely different masters and serve entirely different purposes.
Third-Party Rating
- Who runs it: private companies (ARG/US, Wyvern) and a non-profit council (IBAC for IS-BAO)
- Status: voluntary — you choose to pursue it
- Audience: charter brokers, flight buyers, insurers, corporate travel departments
- What you get: a tier or stage (Platinum, Wingman PRO, Stage 3) and a marketable credential
- Failure mode: lost business / lost trips — but not an FAA enforcement action
FAA Part 5 SMS
- Who runs it: the Federal Aviation Administration
- Status: mandatory for qualifying Part 135 holders under the 2024 final rule
- Audience: your FSDO and Principal Operations Inspector
- What you get: regulatory compliance — and a filed §5.9 Declaration of Compliance
- Failure mode: a compliance finding or enforcement action against your certificate
The dangerous assumption
"We've been ARGUS Platinum / IS-BAO Stage 3 for years, so the SMS rule is handled." It isn't — automatically. A strong rating means you almost certainly do the work of an SMS and have the evidence. But the FAA does not read your ARGUS or IS-BAO certificate and check a box. You must reconcile your program to the specific Part 5 sections and file your own Declaration of Compliance under §5.9 by May 28, 2027.
For the full mechanics of the rule itself, see our deep dives on the FAA Part 135 SMS 2027 deadline and the detailed Part 135 SMS requirements. For the filing specifically, see the FAA SMS Declaration of Compliance.
The Three Programs — Factually
ARGUS, Wyvern, and IS-BAO are the three names that come up most for Part 135 and business-aviation operators (ACSF's Industry Audit Standard is a fourth). Here is what each one actually is — and, importantly, what each one is not. All three are independent programs and registered marks of their respective organizations.
ARGUS (ARG/US International)
Private audit & rating company (an SGS company, founded 1995)
Tiers / stages
Gold · Gold Certified · Platinum · Platinum Elite
What it is
Ratings that validate maintenance, training, and safety practices, surfaced to charter buyers through the CHEQ rated-operator database and the TripCHEQ trip due-diligence tool. ARG/US also sells SMS software separately — but the rating is a credential, not the FAA SMS.
Relationship to the FAA SMS rule
Not an FAA program. A rating is not the Part 5 SMS and is not the §5.9 Declaration of Compliance.
Wyvern (Wingman Standard)
Private air-charter safety audit company
Tiers / stages
Wingman Certified · Wingman PRO · PASS reports
What it is
The first air-charter audit standard in the industry, built on ICAO commercial air transport standards and SMICG guidance for SMS. The PASS (Pilot & Aircraft Safety Survey) report supports trip-specific safety vetting for charter buyers and sellers.
Relationship to the FAA SMS rule
Not an FAA program. A Wingman audit overlaps with Part 5 evidence but does not develop or file your Part 5 SMS.
IS-BAO (IBAC)
Voluntary, ICAO-recognized international industry standard (est. 2002)
Tiers / stages
Stage 1 · Stage 2 · Stage 3
What it is
Administered by the International Business Aviation Council, IS-BAO is built around a scalable SMS. Stage 1 confirms the SMS infrastructure is established; Stage 2 confirms safety risks are effectively managed; Stage 3 demonstrates a fully integrated, sustained safety culture.
Relationship to the FAA SMS rule
Not an FAA regulation. NBAA states IS-BAO is complementary to — not a substitute for — national authority requirements.
Trying to decide between them, or wondering what each audit will ask for? We cover those questions head-on in ARGUS vs. Wyvern vs. IS-BAO, the difference between IS-BAO Stage 1, 2, and 3, and the document-prep guides how to prepare for an ARGUS audit and the ARGUS / Wyvern audit document checklist.
Where They Overlap — and Where They Don't
Here is the good news: the overlap is real and substantial. Wyvern's Wingman Standard is explicitly built on ICAO commercial air transport standards and SMICG guidance for SMS. IS-BAO is an ICAO-recognized standard organized around an SMS. ARGUS audits examine the same safety practices the FAA cares about. So a great deal of the evidence you assemble for a third-party audit is directly relevant to Part 5.
Evidence that typically serves both the third-party audit and Part 5
And here is the hard line — the places where the third-party credential simply cannot stand in for the FAA requirement:
The §5.9 Declaration of Compliance
There is no version of an ARGUS, Wyvern, or IS-BAO certificate that is the FAA Declaration of Compliance. The declaration is an affirmative filing the operator makes to the FAA under §5.9. A third-party auditor does not submit it for you.
Reconciliation to the specific Part 5 sections
A third-party standard maps closely to Part 5 but is not identical to it. Part 5 has its own structure — Safety Policy (§5.21–§5.27), Safety Risk Management (§5.51–§5.57), Safety Assurance (§5.71–§5.75), Safety Promotion (§5.91–§5.93), and SMS documentation/recordkeeping (§5.95–§5.97). Your program must demonstrably satisfy those sections, in those terms.
FAA ownership and surveillance
Your SMS is evaluated by your FSDO Principal Operations Inspector, not by the rating body. When the FAA conducts SMS surveillance, it asks for your Part 5 records — and it is the FAA's judgment, under federal regulation, that determines compliance.
The right mental model: one library, two consumers
Don't build two parallel paper trails — one for the auditor and one for the FAA. Build a single, well-organized compliance evidence library. The ARGUS / Wyvern / IS-BAO auditor draws from it; the FAA draws from it; and you maintain it once. That is exactly the discipline a Part 5 SMS demands anyway — see our Part 135 SMS gap-analysis guide.
One audit, one inspector, one library — be ready for both
FileFlo's free FAA readiness score takes about 3 minutes and surfaces the document gaps most likely to trip you up — whether the next person asking is a charter broker's auditor or your FAA Principal Operations Inspector. No signup required.

If You Already Hold a Rating, Here's What's Still Left for the FAA
If you carry ARGUS Platinum, Wyvern Wingman PRO, or IS-BAO Stage 2/3, you are in an excellent position. You almost certainly already operate the substance of an SMS and have the evidence to prove it. The remaining work is targeted and finite — it is reconciliation and a filing, not a rebuild.
Map your program to the four Part 5 components
Lay your existing SMS against Safety Policy, Safety Risk Management, Safety Assurance, and Safety Promotion. Most of it will line up. Note where your third-party standard required something Part 5 doesn't, and — more importantly — where Part 5 expects something your standard didn't specifically demand.
Run a Part 5 gap analysis
Identify the specific sections (§5.21 through §5.97) where your evidence is thin or where wording must be reconciled to FAA terms. This is the single highest-value step and the standard way to know exactly what's missing.
Organize records for FAA retrieval
Your auditor accepted your filing system; your Principal Operations Inspector will ask for specific records on demand. Make sure every Part 5 record is current, complete, and retrievable in minutes — not buried across shared drives and email threads.
File the §5.9 Declaration of Compliance
Submit the declaration to the FAA in the form and manner acceptable to the Administrator, no later than May 28, 2027. No third-party credential does this for you. Confirm the specifics with your assigned FSDO.
What costs to expect (2026, indicative ranges only)
None of these programs publish a single fixed price, and Part 5 SMS implementation has no FAA fee. Costs vary widely with fleet size, number of bases, operational complexity, and whether you use outside consultants. As of 2026, treat figures as ranges, get a current quote, and budget for recurring (not one-time) effort:
- Third-party audits (ARGUS / Wyvern / IS-BAO): priced per audit and per cycle by the audit body; scope-dependent. Get a direct quote — see our audit cost breakdown.
- Part 5 SMS implementation: no FAA filing fee; your cost is internal time plus any consultant or software you choose.
- Ongoing: both the rating and the SMS are recurring obligations — renewals, recurrent training, and continuous record upkeep.
Where FileFlo Fits: The Evidence Layer for Both the Audit and the SMS
FileFlo holds the proof — it is not an auditor and does not grant a rating or run your SMS
FileFlo is a compliance document intelligence platform: a read-only proof layer that makes you audit-ready. It classifies 600+ document types against the governing regulation, tracks expirations, and produces an organized evidence binder on demand. It does not issue or guarantee an ARGUS, Wyvern, or IS-BAO rating, does not conduct your audit, does not build or operate your Part 5 SMS, and does not provide legal advice. It holds the documents that prove your program exists — for whoever is asking.
The whole point of this article is that you have one evidence library serving two consumers — the third-party auditor and the FAA. That is exactly the problem FileFlo is built for. When a charter broker's auditor or your Principal Operations Inspector asks for a record, the answer should be a 60-second retrieval, not a frantic search.
Classification against the governing CFR
Every uploaded record — safety policy, risk assessment, audit report, corrective action, training certificate — is classified against the section it satisfies (Part 5 and the broader Part 135 stack), so nothing is misfiled and nothing goes missing before an audit.
Expiration & recurrence tracking
Recurrent SMS training, audit-cycle records, and currency items carry recurrence. FileFlo surfaces gaps 90, 60, and 30 days out — before they become a finding at either a Wingman/IS-BAO audit or an FAA surveillance visit.
One-click evidence binder
Generate an organized, indexed evidence binder on demand. The same library that supports your ARGUS, Wyvern, or IS-BAO audit preparation also produces a Part 5-organized binder for the FAA.
Full Part 135 coverage, not just SMS
FileFlo classifies records across the whole Part 135 footprint alongside Part 5 — manuals and revision history, pilot currency, recordkeeping, and drug-and-alcohol program records — so audit prep and FAA readiness share one source of truth.

Frequently Asked Questions
Does an ARGUS rating satisfy the FAA Part 135 SMS rule?
No. An ARGUS rating (Gold, Gold Certified, Platinum, or Platinum Elite) is a private, third-party safety audit and rating issued by ARG/US International — not the FAA, and not a regulation. The FAA's 2024 Safety Management System final rule requires every qualifying Part 135 certificate holder to develop and implement an SMS that conforms to 14 CFR Part 5, and to submit a Declaration of Compliance to the FAA by May 28, 2027. An ARGUS rating does not file that declaration and is not accepted by the FAA in place of it. The two can overlap — an ARGUS audit examines safety practices and ARG/US also sells SMS software — but the rating itself is a separate, voluntary credential. You still own the Part 5 SMS and the declaration.
Is IS-BAO the same as FAA SMS, or does IS-BAO registration meet Part 5?
They are not the same, and IS-BAO registration does not by itself meet 14 CFR Part 5. IS-BAO (the International Standard for Business Aircraft Operations, administered by the International Business Aviation Council) is a voluntary, ICAO-recognized industry standard with three registration stages, and it is built around an SMS. But it is an international industry program, not a U.S. federal regulation. NBAA states plainly that IS-BAO is complementary to — not a substitute for — national civil aviation authority requirements. A mature IS-BAO Stage 2 or Stage 3 SMS gives you a strong head start on Part 5 and much of the same evidence, but you still must reconcile your SMS to the specific Part 5 sections and submit the FAA Declaration of Compliance by May 28, 2027.
Does a Wyvern Wingman audit count as a Part 135 SMS?
No. Wyvern's Wingman Standard is a private air-charter safety audit standard (Wyvern was the first air-charter audit standard in the industry), and Wingman Certified or Wingman PRO status is a voluntary credential — not an FAA SMS and not a regulatory filing. The Wingman Standard is built on ICAO commercial air transport standards and the Safety Management International Collaboration Group (SMICG) guidance for SMS, so a Wingman audit overlaps heavily with Part 5 evidence. But passing a Wingman audit does not develop your Part 5 SMS for you, and it does not submit the Declaration of Compliance the FAA requires from Part 135 operators by May 28, 2027. The audit can support your SMS; it does not replace it.
What is the difference between a third-party safety rating and the FAA SMS rule?
A third-party rating (ARGUS, Wyvern, IS-BAO, ACSF) is a voluntary, market-facing credential issued by a private organization. Charter brokers and flight buyers use it to vet operators. The FAA Part 5 SMS rule is mandatory federal regulation: under the 2024 final rule, qualifying Part 135 certificate holders must build and operate a Safety Management System across four components — Safety Policy, Safety Risk Management, Safety Assurance, and Safety Promotion — and submit a Declaration of Compliance to the FAA by May 28, 2027. The rating is something the market wants; the SMS is something the law requires. They draw on similar safety practices and a lot of the same records, but only the FAA SMS and the §5.9 declaration satisfy the rule.
Can my ARGUS, Wyvern, or IS-BAO audit evidence be reused for Part 5 SMS?
Yes — and that overlap is the practical reason to keep your records organized. Because IS-BAO, Wingman, and ARGUS audits all examine safety practices that map closely to ICAO/SMICG SMS principles, much of the documentation you assemble for those audits is directly relevant to Part 5: hazard identification records, risk assessments, internal audit reports, corrective actions, safety training completions, and your safety policy. The work is reusable, but it is not automatically reconciled to the FAA's specific Part 5 sections, and a third-party audit certificate is not the §5.9 Declaration of Compliance. The right model is one well-kept evidence library that serves both the third-party auditor and the FAA — not two separate paper trails.
When is the Part 135 SMS Declaration of Compliance due?
Under 14 CFR §5.9, persons authorized to conduct operations under Part 135 (and air-tour operators holding a Letter of Authorization under §91.147) must develop and implement an SMS and submit a Declaration of Compliance to the FAA no later than May 28, 2027. It is a single date — there is no aircraft-count or IFR threshold within Part 135, and single-pilot operators face the same deadline even though §5.9 scales certain requirements for them. Holding an ARGUS, Wyvern, or IS-BAO credential does not change, extend, or satisfy that date. Always confirm your specific obligation with your assigned FSDO principal inspector.
Do Part 145 repair stations or Part 91 flight departments have to comply with Part 5?
The 2024 SMS final rule amended Part 5 applicability (§5.1) to cover Part 121 air carriers, Part 135 certificate holders, §91.147 air-tour LOA holders, and certain Part 21 design and production certificate holders. Part 145 certificated repair stations are not included in that general mandate — though the FAA encourages voluntary SMS adoption and U.S. repair stations holding EASA approvals face SMS expectations through the bilateral framework. Most Part 91 corporate flight departments are likewise outside the mandate and adopt SMS voluntarily, often through IS-BAO. So for a Part 145 shop or a Part 91 department, a third-party audit or a voluntary SMS is a business and safety decision, not a Part 5 filing obligation — but the records discipline still pays off.
If I have a Platinum or Stage 3 rating, what is still left to do for the FAA?
A mature program — ARGUS Platinum, Wingman PRO, or IS-BAO Stage 3 — means you likely already operate the substance of an SMS and have the evidence to prove it. What is still left is FAA-specific: map your existing SMS to the four Part 5 components and their sections, close any gaps the FAA framework expects that your audit standard did not specifically require, organize your records so a Principal Operations Inspector can retrieve them on request, and submit the Declaration of Compliance under §5.9 by May 28, 2027. In other words, the heavy safety-program lifting is mostly done; the remaining work is reconciliation, documentation, and the federal filing. A gap analysis against Part 5 is the standard way to find what is missing.
Be ready to produce every record an auditor — or the FAA — asks for
A rating is what the market wants; the Part 5 SMS is what the FAA requires.
