Direct Answer
During an FAA Part 135 ramp inspection, an inspector approaches your aircraft — usually unannounced — presents credentials, and works through three areas: the airmen, the aircraft, and the operation. They ask the crew for the pilot certificate, medical, and photo ID required by 14 CFR 61.3; confirm the ARROW documents required aboard by 14 CFR 91.203 (airworthiness certificate displayed, registration, radio license for international, operating limitations, weight and balance); look at the aircraft's condition and dated inspections; and check the Part 135 items — the operating information aboard under 14 CFR 135.83, the load manifest under 14 CFR 135.63, MEL deferral under 14 CFR 135.179, and that the flight is within your authority.
You are required to allow the inspection under 14 CFR 135.73 and to present your documents under 14 CFR 61.3, but you have the right to know who the inspector is, to be treated professionally, and to confirm answers from your records rather than guess. A routine ramp check is short and uneventful when your documents are current and aboard — the findings that turn up are almost always records-and-currency gaps, not unsafe flying.
This is the experience guide — what a ramp check feels like and how it unfolds. For the inspector's exact item list, see the Part 135 ramp inspection checklist; for the documents you should stage in each aircraft, see the ramp-check document checklist.

What an FAA Ramp Inspection Actually Is (and Why It Happens)
A ramp inspection — the "ramp check" — is a surveillance activity an FAA aviation safety inspector performs at the aircraft: on the ramp, at the FBO, or just before departure, rather than at your office. FAA guidance (FAA Order 8900.1) describes it as a way to observe the aircraft and crew in their normal operating environment and verify the documents that must be carried. It is a normal part of operating in the system — not, by itself, an accusation that you did something wrong.
The inspector's authority is statutory. 49 U.S.C. 44709 lets the Administrator "reinspect at any time a civil aircraft" and reexamine an airman, and 14 CFR 135.73 requires each Part 135 certificate holder and each person it employs to allow the FAA, "at any time or place, to make inspections or tests… to determine the holder's compliance." That is why a ramp check can be unannounced and why declining one is not really an option for a certificate holder.
Why an inspector might ramp-check you
- Random surveillance. Part 135 operators are higher on the FAA's surveillance priority than general-aviation pilots, so a routine, no-cause check is common.
- Something observed. An inspector who notices a possible discrepancy — at an airport, an event, or on the ramp — may follow up with a check.
- A complaint or referral. A reported concern can prompt a check, though that does not presume any violation.
- Risk signals in your file. Recent findings, an incident, new aircraft, or op-spec amendments can raise the frequency of surveillance under the FAA's risk-based model.
A ramp check is a spot check — not your base audit
The inspector is not pulling your training files, your General Operations Manual revision history, or your full maintenance records on the ramp — those live at your base and are reviewed during a separate Safety Assurance System (SAS) surveillance visit or base audit. The ramp check verifies that this flight, right now, is legal. That distinction is why the findings are almost always "a document was not aboard" rather than "the program is unsound."
How a Part 135 Ramp Check Unfolds, Step by Step
Every inspector is a little different, but a routine ramp check follows a recognizable arc. Here is what to expect from the moment they walk up to the debrief — with each step tied to the rule behind it.
The approach and the introduction
A ramp check is normally unannounced. An FAA aviation safety inspector walks up — at the FBO desk, on the ramp, or as you preflight — presents FAA credentials, and explains the scope of what they intend to look at. There is no ambush: a professional inspector identifies themselves and their FSDO before anything else. This is the moment to be courteous, note who they are, and set a cooperative tone.
Airman documents — the crew goes first
The inspector asks each required crewmember for the three documents 14 CFR 61.3 requires in your physical possession or readily accessible: your pilot certificate, your medical certificate, and government photo identification. They check that the category, class, and any type rating match the aircraft and the operation, and that the medical class is appropriate and current. A missing or expired item here is a finding on a flight that may otherwise be perfectly safe.
14 CFR 61.3Aircraft documents — the ARROW set
Next the inspector confirms the documents that must travel with the aircraft under 14 CFR 91.203, which pilots memorize as ARROW: Airworthiness certificate (and it must be displayed at the cabin or cockpit entrance), Registration certificate, Radio station license (international only), Operating limitations (the approved flight manual, placards, and markings), and Weight and balance data. They physically look for the airworthiness certificate on display and check the registration matches the N-number on the aircraft.
14 CFR 91.203A look at the aircraft and the dated inspections
The inspector does a walk-around-level look for obvious unairworthy conditions — leaks, tire and brake condition, damage, missing panels, required markings — and verifies time-limited inspection dates from the records: the transponder within the preceding 24 calendar months (14 CFR 91.413), the ELT within 12 (14 CFR 91.207), and the altimeter system within 24 for IFR (14 CFR 91.411). This is not a maintenance inspection; it is a confirmation that the aircraft presents as airworthy and the calendar items are current.
14 CFR 91.7, 91.413, 91.207The Part 135 layer — manifest, charts, MEL, authority
This is where a Part 135 ramp check goes beyond the Part 91 job aid. The inspector looks for the operating information 14 CFR 135.83 requires aboard (cockpit and emergency checklists, pertinent and IFR charts), the load manifest the pilot in command must carry under 14 CFR 135.63, that any inoperative item is properly deferred under an approved MEL (14 CFR 135.179), and that the flight is the kind of operation your certificate and operations specifications authorize.
14 CFR 135.63, 135.83, 135.179The debrief
The inspector closes by debriefing the crew on what they found. If everything is in order, that is the end of it — a brief, uneventful conversation. A paperwork discrepancy is typically documented for follow-up; a genuine airworthiness issue can keep the aircraft on the ground until resolved. Repeat or systemic problems can escalate beyond the ramp into the FAA’s broader surveillance and, in serious cases, certificate-action processes that carry their own notice-and-response protections under 49 U.S.C. 44709.
The single biggest variable in how this goes is how fast you can produce what is asked. A crew that hands over the airman documents and shows the required aboard-documents in moments turns the whole thing into a brief, professional conversation. A scramble through a flight bag — or a call back to the office to find a transponder-test date — stretches the check out and invites a closer look. Speed is not luck; it is the product of a record system that keeps everything current and retrievable.

Run the Free FAA Readiness ScoreYour Obligations and Your Rights
A ramp check is not a negotiation, but it is not a one-way street either. You have clear obligations — and clear rights. The constructive posture is simple: be professional, cooperative, and factual. Produce what is asked, give the inspector room, and answer what you know.
On answering questions: you are required to allow the inspection and produce required documents, but you are not required to speculate or guess. If you are unsure of a date or a detail, it is entirely appropriate to say you will confirm it from your records — an accurate "let me verify that" is far better than an inaccurate guess that becomes part of the record.
If the inspector finds a discrepancy, it does not automatically become an enforcement case. Many findings are documented for follow-up and corrected administratively. Where a matter could lead to certificate action, the process carries its own protections under 49 U.S.C. 44709 — notice of the charges and, except in emergencies, an opportunity to respond, with appeal rights to the NTSB. For what happens when a flight does not pass and the enforcement side of the picture, see FAA fines for Part 135 paperwork violations and the FAA crackdown on illegal (grey) charter. This is a compliance-document perspective, not legal advice — consult an aviation attorney about your specific situation.
How to Make an Unannounced Ramp Check a Non-Event
Because a ramp check arrives without warning, you cannot prepare for it the night before — you have to already be ready. Four habits eliminate nearly every routine ramp finding before an inspector ever walks up.
Keep a complete document set in every aircraft
The ARROW documents, the current airworthiness certificate displayed at the entrance, the 135.83 checklists and charts, and the load-manifest workflow — standardized so any pilot can produce the set in seconds, in any of your aircraft.
Track every expiration an inspector reads off a record
Medical certificates by pilot, and transponder (24 mo), ELT (12 mo), and altimeter (24 mo) inspection dates by aircraft. A 90/60/30-day alert on each removes the entire category of "interval lapsed" findings.
Run a clean MEL deferral log
Keep the approved MEL current and ensure every inoperative item is placarded and recorded with a record available to the pilot. An undocumented inoperative item is one of the few ramp findings that can actually stop a flight.
Brief crews on the ramp-check posture
Professional, cooperative, factual. Note who the inspector is, produce what is asked, give them room, and answer what you know — confirm anything you are unsure of from the records rather than guessing.
FileFlo: the proof layer that makes every ramp-check document producible on demand
FileFlo is a compliance document intelligence platform — a read-only proof layer that sits alongside your existing stack (scheduling, maintenance tracking, training software) and organizes the records those systems produce. It does not conduct the inspection, represent you to the FAA, or give legal advice, and it is not a replacement for your safety management system, dispatch, or maintenance tracking. What it does is keep the airman, aircraft, and operation records an inspector asks for current and instantly retrievable. It classifies over 600 document types against the governing CFR, tracks expiration windows on every medical and equipment inspection, and lets you pull any record — a pilot's medical, a transponder test date, the current airworthiness release — on demand.
For Part 135 on-demand charter operators, that means when an inspector walks up to the aircraft, the answer to "can I see the…" is already yes — not a scramble through a flight bag or a call back to the office.

Frequently Asked Questions
What happens during an FAA ramp check?
An FAA aviation safety inspector approaches your aircraft — usually at the FBO or on the ramp, often without advance notice — presents credentials, and explains what they are going to look at. They then work through three areas in roughly this order: the airmen, the aircraft, and the operation. From the crew, they ask for the documents 14 CFR 61.3 requires in your possession — pilot certificate, medical certificate, and photo ID. On the aircraft, they confirm the documents 14 CFR 91.203 requires aboard (a current airworthiness certificate displayed at the cabin or cockpit entrance, plus a valid registration certificate), do a walk-around-level look at the aircraft's condition, and verify time-limited inspection dates from the records. For a Part 135 flight, they add the operating information 14 CFR 135.83 requires aboard, the load manifest under 14 CFR 135.63, and that the flight is within the operator's authority. At the end they debrief you on anything they found. A routine ramp check is a short documents-and-condition spot check, not a deep records audit.
What is an FAA ramp inspection and why does it happen?
A ramp inspection — what most pilots call a "ramp check" — is a surveillance activity an FAA inspector performs at the aircraft rather than at your office. FAA guidance (Order 8900.1) frames it as a way to observe the aircraft and crew in their normal operating environment and verify the documents that must be carried. The inspector's authority comes from 49 U.S.C. 44709, which lets the Administrator reinspect aircraft and reexamine airmen at any time, and from 14 CFR 135.73, which requires each Part 135 certificate holder and its employees to allow the FAA to make inspections "at any time or place" to determine compliance. A ramp check can be triggered by random surveillance, by something an inspector observes, or by a complaint — it is a normal part of operating in the system, not an accusation.
Do I have to comply with an FAA ramp check?
Yes. As a Part 135 certificate holder you and your crews are required by 14 CFR 135.73 to allow the Administrator to make inspections and tests, at any time or place, to determine compliance — and 49 U.S.C. 44709 gives the FAA broad authority to reinspect aircraft and reexamine airmen. The pilot must present the certificate, medical, and photo ID that 14 CFR 61.3 requires upon request from the Administrator. The constructive posture is professional and cooperative: present your documents, give the inspector room to look at the aircraft, and answer factual questions accurately. You are not obligated to speculate — if you do not know an answer, it is appropriate to say you will confirm it from your records rather than guess.
What documents does the FAA ask for during a ramp check?
The inspector asks the crew for the airman documents 14 CFR 61.3 requires in possession — pilot certificate, medical certificate, and government photo ID — and for the aircraft documents 14 CFR 91.203 requires aboard, which pilots remember as ARROW: Airworthiness certificate (displayed at the cabin or cockpit entrance), Registration certificate, Radio station license (international operations only), Operating limitations (the approved flight manual, placards, and markings), and Weight and balance data. For a Part 135 flight, they also look for the operating information 14 CFR 135.83 requires aboard — the cockpit checklist, the emergency checklist for multiengine or retractable-gear aircraft, and pertinent aeronautical and IFR navigation charts — plus the load manifest the pilot in command must carry under 14 CFR 135.63. The deeper records (training files, the General Operations Manual, full maintenance logs) live at your base and are reviewed in a separate surveillance visit, not on the ramp.
How long does an FAA ramp check take?
There is no fixed duration, but a routine Part 135 ramp check is typically short — often on the order of fifteen to forty-five minutes when the documents are in order. FAA guidance directs inspectors to be courteous and to try to time the check so it does not delay the flight where possible. The length depends almost entirely on how quickly you can produce what is asked: a crew that can hand over the airman documents and show the required aboard-documents in moments turns the check into a brief, uneventful conversation, while a scramble through a flight bag or a call back to the office to find an expiration date stretches it out and invites a closer look.
Can the FAA ramp check me without notice, and can they stop my flight?
Yes to both, within limits. Ramp checks are normally unannounced — 14 CFR 135.73 lets the FAA inspect "at any time or place." Whether a finding stops your flight depends on what it is. A paperwork gap — a medical left at home, a document not aboard — is usually documented for follow-up rather than grounding you on the spot. But a genuine airworthiness issue (an inoperative item not properly deferred under the MEL, an obvious unairworthy condition, a lapsed required inspection) can keep the aircraft on the ground until it is resolved, because the pilot in command is responsible under 14 CFR 91.7 for determining the aircraft is in condition for safe flight. The inspector verifies; the responsibility to fly only an airworthy aircraft is yours.
What are my rights during an FAA ramp check?
You have the right to know who the inspector is — they should present FAA credentials, and you may note their name and office. You have the right to be treated professionally and to have the inspector avoid unnecessarily delaying your flight, consistent with FAA guidance. You are required to present the documents 14 CFR 61.3 and 91.203 cover and to allow the inspection under 14 CFR 135.73, but you are not required to speculate, guess, or make statements you are unsure of — it is reasonable to confirm details from your records. If the inspector identifies a discrepancy, you have the opportunity to understand and respond to it, and any certificate action that might follow carries its own procedural protections under 49 U.S.C. 44709, including notice and, except in emergencies, an opportunity to respond. This is a compliance-document perspective, not legal advice — consult an aviation attorney for questions about your specific rights.
How is a ramp inspection different from a Part 135 base audit?
A ramp inspection is a short, point-of-operation spot check at the aircraft, focused on the documents that must be carried and the aircraft's visible condition for the flight in front of the inspector. A base audit or SAS surveillance visit happens at your principal operations base and goes much deeper — the inspector reviews the General Operations Manual and its revision history, the full per-pilot training and currency files, maintenance and airworthiness records, the drug and alcohol program, and your operational control system. The ramp check verifies that this flight, right now, is legal; the base audit verifies that your program is sound over time. Both draw from the same body of compliance records — the difference is depth and location. For the base-audit side, see our companion guide on preparing for a Part 135 FAA surveillance audit.
