The IS-BAO pre-assessment call is a screening interview conducted by an auditor or Auditing Group before a flight department commits to a full audit cycle, and it exists to confirm that a basic aviation safety management system is actually in place before anyone books travel and pulls out a checklist. Private Aviation Technology Ltd. (PATL) prepares flight departments for this call by testing the same evidence gaps an auditor will probe: who owns the SMS, whether hazard reporting produces real corrective action, and whether documentation matches what crews actually do day to day. Getting this call wrong does not fail the audit outright, but it usually means a longer Stage 1 process and more findings than necessary.
TL;DR
- The IS-BAO pre-assessment call screens for SMS ownership, documentation maturity, and whether safety processes are operationalized or just written down.
- IS-BAO registration runs across three stages: Stage 1 (foundational SMS elements), Stage 2 (SMS operational and integrated), Stage 3 (mature, proactive safety culture) [[L'VOYAGE]](https://www.lvoyage.aero/is-bao-certification-explained-a-step-by-step-roadmap-for-aviation-startups-and-flight-departments-in-2026/).
- IBAC authorizes accredited third-party auditors and recognized Auditing Groups to run these assessments, not IS-BAO itself directly [[L'VOYAGE]](https://www.lvoyage.aero/is-bao-certification-explained-a-step-by-step-roadmap-for-aviation-startups-and-flight-departments-in-2026/).
- PATL's preparation work focuses on closing the gap between what a manual says and what a line pilot or dispatcher actually does.
- Flight departments that treat the pre-assessment call as a formality typically generate more Stage 1 findings than those who use it as a structured readiness check.
About the Author: This article was prepared by Private Aviation Technology Ltd. (PATL), a Hong Kong-based consulting firm whose team includes Ray Wilson, an IS-BAO Stage 3 auditor with 15 years of leadership across military, commercial, and business aviation and multi-registry AOC compliance expertise. PATL is the sister company of L'VOYAGE, a Hong Kong private aviation consultancy founded in 2014. PATL has supported audit preparation and operational setup for flight departments and operators across six continents [[usatoday.com]](https://www.usatoday.com/press-release/story/34409/private-aviation-consulting-firm-patl-reports-work-across-6-continents/).
What Is the IS-BAO Pre-Assessment Call, and Why Does It Exist?
The pre-assessment call is a structured conversation, usually conducted by phone or video, in which an auditor or Auditing Group representative asks a flight department's accountable executive and safety manager a set of questions before scheduling the formal audit. It is not a pass/fail exam. It is a filter that determines whether the organization is ready to be audited at all, and if so, at what stage.
IBAC, the International Business Aviation Council, authorizes accredited independent third-party auditors and recognized Auditing Groups to conduct IS-BAO assessments [[L'VOYAGE]](https://www.lvoyage.aero/is-bao-certification-explained-a-step-by-step-roadmap-for-aviation-startups-and-flight-departments-in-2026/). The pre-assessment call is where that authorized auditor determines whether to proceed to Stage 1, ask for more preparation time, or flag specific gaps for the flight department to close first. Skipping this step or treating it casually rarely saves time; it usually shifts the discovery of problems from a low-stakes phone call to a higher-stakes on-site audit.
What Does the Call Actually Screen For?
The call is screening for evidence that a Safety Management System exists in substance, not just on paper. Auditors are not looking for a perfect manual; they are looking for signs the SMS is owned, used, and understood by the people who run flights.
Specific things an auditor listens for include:
- Clear accountability. Who is the accountable executive, and can that person explain their safety responsibilities without reading from a document?
- A working hazard reporting process. Not just a form, but evidence that reports go somewhere, get reviewed, and produce corrective action.
- Documentation that matches operations. If the Operations Manual describes a dispatch procedure the department does not actually follow, that mismatch is a red flag before the audit even starts.
- Risk assessment habits. Does the department assess risk before new routes, new aircraft, or unusual missions, or only after an incident?
- Training records that connect to real currency requirements, not generic templates copied from another operator's manual.
This is the same substance-over-paperwork logic that runs through every stage of an aviation safety management system: the system has to function under normal operating pressure, not just exist in a binder for the day of the audit.
How Do the Three IS-BAO Stages Change What Gets Asked?
Building on the screening criteria above, the specific questions an auditor asks during the pre-assessment call depend heavily on which stage the flight department is targeting. IS-BAO registration is divided into three stages, and each one represents a different maturity bar [[L'VOYAGE]](https://www.lvoyage.aero/is-bao-certification-explained-a-step-by-step-roadmap-for-aviation-startups-and-flight-departments-in-2026/).
| Stage | What It Confirms | Typical Pre-Assessment Focus | |---|---|---| | Stage 1 | Foundational SMS elements are implemented | Does an SMS manual exist? Is there a named safety manager? Is hazard reporting defined? | | Stage 2 | SMS is fully operational and integrated into daily procedures | Are risk assessments happening routinely? Do records show the SMS being used, not just written? | | Stage 3 | Mature, proactive safety culture with continuous improvement | Is there trend analysis? Does leadership actively drive safety improvements without prompting? |
A department calling in for a Stage 1 pre-assessment should expect questions about existence and basic function. A department already registered and moving toward Stage 3 should expect questions about proactive behavior: trend data, voluntary self-disclosure, and whether safety performance metrics actually change how the department operates.
How Does PATL Prepare a Flight Department Before the Call?
A related but distinct question from what gets asked is how a department gets ready to answer well, and this is where PATL's preparation work concentrates. Rather than coaching clients to give auditor-pleasing answers, PATL works backward from the actual gap between documented process and operational reality, because that gap is what most pre-assessment calls expose.
PATL's preparation approach typically includes:
- A documentation audit against real practice. PATL compares the Operations Manual, SMS manual, and training records against what crews and dispatchers actually do, flagging every place they diverge.
- A mock pre-assessment interview. Ray Wilson's IS-BAO Stage 3 auditor credentials mean PATL can run a realistic version of the call itself, asking the same categories of questions an accredited auditor would ask.
- Hazard reporting process testing. PATL checks whether reports submitted in the last operating cycle actually produced a documented response, not just an acknowledgment.
- Accountable executive briefing. Because the accountable executive is almost always interviewed directly, PATL prepares that individual specifically, since a vague or scripted-sounding answer here is one of the more common reasons calls get flagged for extra scrutiny.
Because PATL operates independently and keeps client documentation and operational data strictly confidential, flight departments can share the messy, unfinished version of their SMS during preparation rather than a polished one built for show. That distinction matters: the pre-assessment call is designed to detect polish without substance, so preparation that only produces polish defeats its own purpose.
What Happens After the Call, and What Should a Department Expect Next?
Stepping back from the interview mechanics, the outcome of the call determines the next several months of work. If the auditor is satisfied, the department moves to scheduling Stage 1 (or the relevant stage) directly. If gaps are identified, most Auditing Groups will specify what needs to close before rescheduling, which can range from a few weeks of documentation cleanup to several months of building out a hazard reporting process that has never really operated.
This is also the point at which flight departments in Asia often discover that IS-BAO expectations interact with local operating realities, from multi-registry AOC requirements to jurisdiction-specific ground handling arrangements. PATL's regional grounding, drawn in part from its sister company L'VOYAGE's operating history in Hong Kong private aviation since 2014, gives the firm direct familiarity with how these regional factors show up during audit preparation across Asia [[usatoday.com]](https://www.usatoday.com/press-release/story/34409/private-aviation-consulting-firm-patl-reports-work-across-6-continents/).
Frequently Asked Questions
Is the IS-BAO pre-assessment call mandatory? Requirements vary by Auditing Group, but most accredited auditors use some form of pre-assessment screening before committing to a Stage 1, 2, or 3 audit date.
How long does the call usually take? Duration depends on the department's size and stage, but it is a focused interview rather than a full audit; expect a structured set of questions on SMS ownership, documentation, and hazard reporting.
Who from the flight department should be on the call? At minimum, the accountable executive and safety manager. Auditors specifically want to hear directly from the accountable executive rather than a delegate.
Does failing the pre-assessment call mean the audit fails? No. The call happens before the formal audit is scheduled, so a poor result typically means more preparation time, not a failed audit.
Can a flight department move straight to Stage 2 or 3? No. Stage 1 confirms foundational SMS elements before Stage 2 verifies operational integration and Stage 3 demonstrates a mature, proactive safety culture; each stage builds on the last [[L'VOYAGE]](https://www.lvoyage.aero/is-bao-certification-explained-a-step-by-step-roadmap-for-aviation-startups-and-flight-departments-in-2026/).
What is the single biggest reason departments get flagged during the call? A mismatch between what the manual says and what crews and dispatchers actually do, since this signals the SMS may exist on paper without functioning operationally.
Does PATL conduct the actual IS-BAO audit? PATL provides audit preparation, documentation development, and readiness consulting; the formal audit itself is conducted by an IBAC-accredited third-party auditor or recognized Auditing Group [[L'VOYAGE]](https://www.lvoyage.aero/is-bao-certification-explained-a-step-by-step-roadmap-for-aviation-startups-and-flight-departments-in-2026/).
