Every Part 135 certificate lives under continuous FAA oversight. A ramp check can happen on any tarmac, surveillance under FAA Order 8900.1 samples your records on the FAA's schedule, and a base inspection digs deep into training files, maintenance, and OpSpecs. The inspector asks for the same things every time, pilot certificates and medicals, recurrent-training and checkride currency, aircraft airworthiness documents, and operations specifications.
On top of that ongoing oversight, the clock is now running on a major new requirement. On April 26, 2024 the FAA published its final rule extending Safety Management Systems to all Part 135 operators (effective May 28, 2024). There is no fleet-size threshold, a single-aircraft certificate is in scope just like a 100-tail fleet, and every affected operator must submit a Declaration of Compliance to the FAA no later than May 28, 2027 (14 CFR 5.9).
The hardest part of every FAA interaction is rarely the flying, it is producing complete, current records on demand. An expired pilot medical or a lapsed recurrent-training date is not a complex failure; it is an administrative oversight that the right software catches automatically, weeks before an inspector ever sees it.
Primary regulations referenced in this guide: 14 CFR Part 135 (operating requirements: commuter & on-demand), 14 CFR 135.293 (pilot ground & flight competency), 14 CFR 135.297 (instrument proficiency check), 14 CFR 135.299 (line checks), and 14 CFR Part 5 (Safety Management Systems).
A clear distinction worth keeping straight
The tools below split into three layers. Your SMS (part135sms.com, Baldwin, SMS Pro) manages safety risk under Part 5. Your flight-operations system (FlyAXS, myFLIGHTDATA) runs scheduling, dispatch, and duty time. Your LMS (eLeaP) delivers training. FileFlo is the records and proof layer underneath all three, it does not replace them. Match the tool to the layer you are missing.
The 7 Best FAA Audit Preparation Platforms
Ranked for the records-readiness use case: document depth, pilot-currency tracking, inspector-binder export, and value for Part 135 operators of every size. Each tool is credited where it genuinely leads.
FileFlo
Top Pick, Best OverallBest For
Part 135 operators (1-160+ aircraft) that need pilot-currency tracking, document classification, and an inspector-ready records binder without buying another ops platform
Key Feature
An audit packet with the per-pilot currency matrix and each document's standing, and an inspector link limited to one aircraft or one crew
FAA-Specific
14 CFR Part 135 requirement-mapped classification, a per-pilot currency matrix, an item opened 45 days before a check, medical or annual comes due
Strengths
- AI document classification cited to the rule, upload a check record (the current FAA check template or an older 8410-3) or a COI and FileFlo files it against the matching 14 CFR 135 requirement
- Per-pilot currency matrix: medical, §135.293 competency, §135.297 instrument proficiency, §135.299 line check and §135.351 recurrent training, dated in calendar months with base-month crediting
- An item opens 45 days before a check, medical or annual comes due, so the lapse surfaces before the inspector does
- One-click FAA inspector binder plus a dedicated ramp-check mode that pulls the exact records an inspector asks for at the aircraft
- An export of crew currency, training and aircraft records as of one date, tagged to the Wyvern Wingman clauses and the ARGUS audit categories, prepared for the audit
- Starts with the Audit-Ready Crew Records Setup, then per aircraft per month
- Anthropic Zero Data Retention on the AI layer, your documents are not used to train models
Limitations
- Not an SMS, pair with part135sms.com, Baldwin, SMS Pro, or your existing Part 5 program
- Not a flight-operations / scheduling system (FOS), pair with FlyAXS, myFLIGHTDATA, or your dispatch platform
- Not a learning-management system (LMS), does not deliver courseware (use eLeaP or your training vendor); it tracks the resulting records
- No real-time flight, duty-time computation, or maintenance-due forecasting, it stores and proves the records those systems produce
Our take: FileFlo is the purpose-built answer to the FAA audit-readiness problem on the records side: it classifies pilot, training, aircraft, and operator documents against the matching 14 CFR Part 135 requirement, computes each pilot's checks and medical in a per-pilot currency matrix that cites the rule, and produces an inspector-ready binder (plus a ramp-check mode) on demand. It deliberately does not try to be your SMS, FOS, or LMS, it is the proof layer that sits underneath them. Aviation starts with the Audit-Ready Crew Records Setup; 16 or more aircraft, air medical and fractional operations are priced by written quote.
Includes 30 days of FileFlo. After 30 days, FileFlo continues at $150 per aircraft per month on this card unless you cancel. We remind you 7 days and 1 day before. Each reminder email has a one-click cancel link. Cancel before day 30 and nothing further is charged. The plan covers 1 to 15 aircraft.
myFLIGHTDATA
Best All-in-One Flight Ops + RecordsBest For
Part 135 operators that want scheduling, pilot legality, flight/duty-time, maintenance tracking, and electronic records in a single flight-operations platform
Key Feature
Flight-operations suite with pilot-legality monitoring, flight/duty-time legality checks, maintenance tracking, EFB, and electronic records
FAA-Specific
Pilot qualification & legality monitoring, flight/duty-time tracking, aircraft maintenance, electronic records (FAA/ICAO/EASA)
Strengths
- Genuine all-in-one flight-ops platform: scheduling, dispatch, pilot legality, and maintenance in one place
- Real-time flight and duty-time legality checking against crew qualifications
- Aircraft maintenance tracking and electronic flight bag (EFB) integration
- Published entry pricing from $45/month (eSMS), $85/month with the flight-ops bundle, rare transparency in this category
- Multi-authority coverage (FAA, ICAO, CAA, EASA) for operators flying internationally
Limitations
- Records are one module inside a broad ops suite, not a dedicated document-intelligence layer
- No AI classification that maps each document to a specific 14 CFR 135 requirement
- Inspector-binder / ramp-check export is not the headline use case
- Operators already committed to another scheduling/FOS platform inherit overlap
Our take: myFLIGHTDATA is a strong choice for an operator that wants scheduling, crew legality, and maintenance unified in one flight-operations system, and its published pricing (from $45/month, $85/month with the flight-ops bundle) is refreshingly transparent. Where FileFlo leads is the records layer itself: rule-cited classification, a per-pilot currency matrix, and an audit packet with a scoped inspector link. The two are complementary, run myFLIGHTDATA for ops and FileFlo as the proof layer underneath.
FlyAXS (Fly Access)
Best for Charter Ops at ScaleBest For
Growing Part 135 charter operators that want scheduling, dispatch, crew, maintenance, and SMS in one modern all-in-one platform
Key Feature
All-in-one charter management, scheduling, dispatch, crew tracking, maintenance, and SMS with AI-assisted operations
FAA-Specific
Part 135 charter operations, crew qualification tracking, maintenance, integrated SMS workflows
Strengths
- Comprehensive Part 135 charter platform: scheduling, dispatch, crew, maintenance, and SMS together
- Built specifically for FAA Part 135 charter operators
- AI-assisted operational workflows across modules
- Integrated SMS helps address the 2024 Part 5 mandate inside the same system
Limitations
- Quote-based pricing, no public rate without a sales conversation
- Broad ops scope means the records layer is not a dedicated document-intelligence engine
- No rule-cited AI classification or one-click FAA inspector binder at FileFlo's depth
- Likely more platform (and cost) than a single-aircraft certificate needs for pure audit prep
Our take: FlyAXS is a serious modern platform for charter operators that want their scheduling, dispatch, maintenance, and SMS unified, and its integrated SMS is a real asset for the 2027 deadline. It is an operations system first. FileFlo complements it as the dedicated records-and-proof layer: rule-cited classification, a per-pilot currency matrix, and an audit packet that an ops platform treats as a secondary feature.
Web Manuals
Best for Manuals & Document ControlBest For
Operators that need controlled, FAA-approvable manuals (GMM, GOM, SMS manual) with change tracking, compliance linking, and audit trails
Key Feature
Manual-management system with automated LEP/TOC/MEL modules, revision control, compliance linking, and audit trails
FAA-Specific
Manual control across Part 135 sub-parts, FAA-approval workflow, compliance library, revision audit trail
Strengths
- Best-in-class controlled-manual authoring and revision management (LEP, TOC, MEL automation)
- Compliance linking ties manual sections to the underlying regulatory requirements
- Automatic change tracking and full audit trail on every manual revision
- Comprehensive compliance library covering Part 135 sub-parts and other authorities (EASA, IOSA, CASA, IS-BAO)
Limitations
- Focused on manuals and procedures, not pilot/aircraft record files or currency tracking
- No pilot-currency expiration alerting (medical, checkrides), different problem domain
- No one-click inspector binder of pilot and aircraft records
- Quote-based pricing oriented toward larger and international operators
Our take: Web Manuals is the leader for keeping your controlled manuals current and FAA-approvable, with audit trails and compliance linking that genuinely shine. That is a different layer from record files and currency. Most operators benefit from both: Web Manuals for the manual library, FileFlo for the pilot, training, and aircraft records an inspector samples during surveillance.
Baldwin Safety & Compliance (a Portside company)
Best SMS with Expert SupportBest For
Operators that want a configured SMS backed by credentialed aviation-safety professionals available 24/7 for implementation and ongoing support
Key Feature
Configurable SMS software plus a team of credentialed safety experts, with AI-assisted form summarization and broad integrations
FAA-Specific
14 CFR Part 5 SMS, configurable forms and reporting, internal evaluation programs, ICAO alignment
Strengths
- Mature SMS platform aligned to 14 CFR Part 5 and ICAO standards
- Credentialed safety experts available 24/7, strong for operators new to SMS
- AI-assisted summarization of safety forms reduces administrative load
- Integrations with ForeFlight Dispatch, Airplane Manager, Okta, NASA ASRS, and more
Limitations
- It is an SMS, not a records / document-intelligence platform
- No per-pilot currency matrix or medical/checkride expiration alerts
- No rule-cited document classification or one-click FAA inspector binder
- Quote-based pricing requires a sales conversation
Our take: Baldwin is an excellent SMS choice, especially for an operator that wants experienced safety professionals guiding the Part 5 build toward the May 2027 deadline. It is squarely an SMS, not a records engine. Pair it with FileFlo so the documents your SMS and operation generate are classified, currency-tracked, and inspector-ready in one place.
part135sms.com (eSMS)
Most Cost-Effective Part 135 SMSBest For
Single-aircraft and small Part 135 certificates that need an affordable, purpose-built electronic SMS to meet the 2027 Part 5 mandate
Key Feature
Part 135-specific eSMS with customizable SMS manual templates and guided program setup aligned to 14 CFR Part 5
FAA-Specific
14 CFR Part 5 SMS, hazard and risk management, SMS documentation, Part 135 manual templates
Strengths
- Purpose-built for Part 135 SMS and 14 CFR Part 5 compliance
- Customizable SMS manual templates plus tailored program-setup services
- Positioned as one of the most cost-effective eSMS options for small operators
- Intuitive interface aimed at small teams implementing SMS for the first time
Limitations
- Scope is SMS, not pilot/aircraft records, currency tracking, or audit-binder export
- No AI document classification mapped to specific 14 CFR 135 requirements
- No 90/60/30/7-day currency alerting on medicals or checkrides
- Larger-fleet pricing (over 6 aircraft) requires a quote
Our take: part135sms.com is a sensible, affordable way for a small certificate to stand up a compliant Part 5 SMS before May 2027. It solves the SMS requirement, not the records-readiness problem. FileFlo handles the other half, classifying and currency-tracking the pilot, training, and aircraft documents an FAA inspector actually asks to see, so a small operator gets both halves without overpaying for either.
eLeaP
Best for Training-Records & LMSBest For
Operators that need to deliver and document recurrent training and crew qualifications through a validated LMS with a built-in audit trail
Key Feature
Learning-management and quality system for regulated industries, pilot recurrency tracking, proficiency-check scheduling, and crew-qualification reporting with an audit trail
FAA-Specific
14 CFR training requirements, pilot recurrency, proficiency-check scheduling, crew-qualification reporting
Strengths
- Validated LMS/QMS built for regulated industries (FAA 14 CFR, OSHA, FDA 21 CFR Part 11)
- Aviation features: pilot recurrency tracking, proficiency-check scheduling, crew-qualification reporting
- Connects training events to competency verification with a complete audit trail
- 2,000+ ready-to-use courses plus a free trial to evaluate
Limitations
- It is an LMS/QMS, it delivers and documents training, it is not a full records-and-proof layer
- No rule-cited classification of arbitrary documents (COIs, airworthiness, OpSpecs)
- No one-click FAA inspector binder spanning pilot, aircraft, and operator records
- Per-user pricing can add up for larger crews
Our take: eLeaP is a strong LMS for operators that want to deliver recurrent training and prove crew qualifications with an audit trail, genuinely useful for the training side of Part 135. It is a learning system, not a document-intelligence engine. FileFlo complements it: eLeaP runs and records the training, FileFlo classifies the resulting certificates and every other audit document and surfaces what is expiring.

How to Choose the Right Platform for Your Certificate
If your goal is being ready for FAA surveillance, a base inspection, or a ramp check
Choose FileFlo. It is the only platform on this list purpose-built around the records-readiness use case, rule-cited document classification, a per-pilot currency matrix, an item opened 45 days before a check, medical or annual comes due, and an audit packet with an inspector link limited to one aircraft or one crew. Aviation starts with the Audit-Ready Crew Records Setup; 16 or more aircraft, air medical and fractional operations are priced by written quote. Start with the free FAA readiness score to see your gaps before you buy.
If you need scheduling, dispatch, crew legality, and maintenance in one ops platform
Evaluate myFLIGHTDATA or FlyAXS. myFLIGHTDATA publishes pricing from $45/month (eSMS), $85/month with the flight-ops bundle, and unifies scheduling, pilot legality, and maintenance; FlyAXS is a broader all-in-one charter platform (quote-based) with integrated SMS. Both are operations systems, pair either with FileFlo for the dedicated records-and-proof layer.
If your immediate priority is standing up an SMS before May 2027
Look at part135sms.com for an affordable, Part 135-specific eSMS, or Baldwin Safety & Compliance if you want credentialed safety experts guiding the build. SMS Pro is another mature, ICAO-compliant option. These solve the Part 5 mandate; FileFlo keeps the underlying records audit-ready alongside whichever SMS you choose.
If keeping controlled manuals FAA-approvable is your pain point
Web Manuals leads on controlled-manual authoring, revision control, compliance linking, and audit trails (GMM, GOM, SMS manual, MEL). That is the manual layer. For the pilot, training, and aircraft record files an inspector samples, FileFlo and Web Manuals serve different needs and work well together.
If you need to deliver and document recurrent training
eLeaP is a validated LMS with pilot-recurrency tracking, proficiency-check scheduling, and a built-in audit trail, plus a free trial. It runs and records the training; FileFlo classifies the resulting certificates and surfaces what is expiring. For the lowest-friction way to assess your overall records readiness first, the free FAA readiness score is the place to start.
A ramp check can happen on any flight, be ready before it does
FileFlo classifies pilot, training, and aircraft documents against the matching 14 CFR Part 135 requirement, computes each pilot's checks and medical in a per-pilot currency matrix, and builds an audit packet with an inspector link limited to one aircraft or one crew. Aviation starts with the Audit-Ready Crew Records Setup; 16 or more aircraft, air medical and fractional operations are priced by written quote.
Includes 30 days of FileFlo. After 30 days, FileFlo continues at $150 per aircraft per month on this card unless you cancel. We remind you 7 days and 1 day before. Each reminder email has a one-click cancel link. Cancel before day 30 and nothing further is charged. The plan covers 1 to 15 aircraft.
Frequently Asked Questions
What is FAA audit preparation software?
FAA audit preparation software helps Part 135 charter operators organize, maintain, and quickly produce the records that an FAA Principal Operations Inspector (POI) or Aviation Safety Inspector requests during surveillance, a base inspection, or a ramp check. This includes pilot certificates and medical certificates, recurrent training and checkride records (14 CFR 135.293/135.297/135.299), aircraft airworthiness and registration documents, maintenance and inspection records, weight-and-balance data, operations specifications, and insurance certificates. The strongest tools classify each document automatically, track currency dates, and assemble an inspector-ready binder. FileFlo is the records and proof layer in this category, it is not the SMS, the flight-operations system (FOS), or the learning-management system.
How much does FAA / Part 135 audit prep software cost?
Pricing varies widely across aviation platforms. Aviation starts with the Audit-Ready Crew Records Setup; 16 or more aircraft, air medical and fractional operations are priced by written quote. myFLIGHTDATA publishes plans starting at $45/month for its eSMS, $85/month with the flight-operations bundle. part135sms.com publicly lists $30/month for 1-3 aircraft and $60/month for 4-6 aircraft (larger fleets require a quote), and eLeaP starts at $5/user/month with volume discounts. Web Manuals, Baldwin Safety & Compliance, and FlyAXS are quote-based, you need a sales conversation to get a number.
What records does an FAA inspector look for during a Part 135 inspection?
During Part 135 surveillance or a ramp check, an FAA inspector typically verifies: (1) each pilot's airman certificate and current medical certificate (14 CFR 61.23 / Part 67); (2) recurrent training, ground/flight competency, and instrument proficiency checks (14 CFR 135.293, 135.297, 135.299); (3) the aircraft airworthiness certificate, registration, and operating limitations; (4) weight-and-balance and aircraft flight manual; (5) maintenance and inspection records and any MEL items; (6) the operations specifications (OpSpecs); and (7) duty-time and rest records. Missing or expired pilot medicals and lapsed recurrent-training currency are among the most common findings. FAA surveillance procedures are governed by FAA Order 8900.1.
Does the 2024 FAA SMS rule apply to my Part 135 operation?
Yes. The FAA published the final SMS rule on April 26, 2024 (effective May 28, 2024), extending Safety Management System requirements under 14 CFR Part 5 to all Part 135 operators and certain Part 91.147 air-tour operators. There is no fleet-size or aircraft-count threshold, single-aircraft certificates are included. Each affected operator must submit a Declaration of Compliance to the FAA no later than May 28, 2027 (14 CFR 5.9), meaning the SMS must be developed, implemented, and documented before that date. FileFlo does not provide the SMS itself, tools like part135sms.com, Baldwin, FlyAXS, and SMS Pro do. FileFlo keeps the underlying records and proof audit-ready alongside whichever SMS you run.
What is the difference between an FAA ramp check, surveillance, and a base inspection?
A ramp check is a brief, often unannounced inspection at the aircraft, the inspector verifies the pilot's certificate and medical, aircraft documents, and a few operational items before or after a flight. Surveillance is the FAA's ongoing, risk-based oversight of a certificate holder under FAA Order 8900.1, sampling pilot, training, maintenance, and operational records over time. A base inspection (or records inspection) is a deeper, scheduled review at the operator's facility covering training files, maintenance programs, OpSpecs, and recordkeeping. All three ask for the same underlying records, which is why having every pilot file, training record, and aircraft document classified and current in one place matters regardless of which form the oversight takes.
Can FileFlo replace my SMS, flight-operations system, or LMS?
No, FileFlo is complementary, not a replacement. Your SMS (part135sms.com, Baldwin, SMS Pro), your flight-operations and scheduling system / FOS (FlyAXS, myFLIGHTDATA), and your learning-management system (eLeaP) each own their domain. FileFlo is the document-intelligence and proof layer underneath them: it classifies each uploaded record against the relevant 14 CFR Part 135 requirement, computes each pilot's checks and medical in a per-pilot currency matrix that cites the rule, opens an item 45 days before a check, medical or annual comes due, and builds an audit packet with each document's standing. FileFlo runs alongside your existing SMS and ops platform.
What happens if a pilot's medical or recurrent training has lapsed when the FAA arrives?
A pilot flying Part 135 with an expired medical certificate is not qualified to act as a required crewmember (14 CFR 61.23 / 135.243), and lapsed recurrent training or a missed competency check under 14 CFR 135.293/135.297/135.299 means that pilot is not current for line operations. Discovered during surveillance or a ramp check, either can trigger findings, removal of the pilot from the schedule, and potential enforcement action under 14 CFR Part 13. FileFlo computes each pilot's checks and medical in a per-pilot currency matrix and opens an item 45 days before one comes due, so the lapse is visible before the inspector arrives. Always confirm currency requirements against your OpSpecs and current 14 CFR.
Stop assembling inspector binders by hand
FileFlo classifies Part 135 records against the matching 14 CFR requirement, computes each pilot's checks and medical in a per-pilot currency matrix, and builds an audit packet with an inspector link limited to one aircraft or one crew. Aviation starts with the Audit-Ready Crew Records Setup; 16 or more aircraft, air medical and fractional operations are priced by written quote. It is the records and proof layer, not your SMS or ops system.
Includes 30 days of FileFlo. After 30 days, FileFlo continues at $150 per aircraft per month on this card unless you cancel. We remind you 7 days and 1 day before. Each reminder email has a one-click cancel link. Cancel before day 30 and nothing further is charged. The plan covers 1 to 15 aircraft. 16 or more aircraft, air medical and fractional operations: by written quote. Request an aviation quote.
