Build SMS architecture that survives audits. PATL designs safety systems tied to your operations, not templates, for IS-BAO, IS-BAH, and AOC compliance.
Most Safety Management Systems look fine on paper until an auditor or regulator starts pulling threads. Private Aviation Technology Ltd. (PATL) builds SMS architecture that holds up under IS-BAO, IS-BAH, and AOC scrutiny because it is designed from operational reality, not copied from a template.
Book a consultation →PATL's team includes an IS-BAO Stage 3 auditor with 15 years of leadership across military, commercial, and business aviation. PATL is the sister company of L'VOYAGE (founded 2014), operating in Hong Kong private aviation. EU ground handling organisations face a general SMS applicability date of 27 March 2028 under Regulations (EU) 2025/20 and 2025/23.
| Common Failure Mode | PATL's Approach |
|---|---|
| Generic template copied from another operator | SMS built around your specific fleet, bases, and registries |
| Safety reporting exists but nobody uses it | Reporting workflow designed into daily operations, not bolted on |
| Risk register updated once a year before audit | Continuous risk assessment tied to operational triggers |
| Documentation owned by one person who leaves | Documentation structured for handover and maintenance |
"Our IS-BAO Stage 3 auditing background means we build SMS systems to pass the same scrutiny we apply when we're the ones auditing."
An SMS is the management system itself: policy, risk management, assurance, and promotion processes that run continuously. IS-BAO is an audit standard that verifies your SMS and broader operation meet International Business Aviation Council benchmarks across three stages. You need a working SMS before an IS-BAO audit can succeed, which is why PATL builds the system first and audits against it second.
Timelines depend on your current documentation state, registry, and operational complexity, so PATL scopes each engagement individually rather than quoting a fixed timeline upfront. A single-aircraft startup with no existing SMS takes longer than an operator refining an existing system ahead of an IS-BAO Stage 2 or 3 audit. PATL evaluates your starting point first.
No. Ground handling organisations with up to 25 FTE per GH unit qualify as non-complex under Commission Delegated Regulation (EU) 2025/20 and get proportionality alleviations, including a scalable SMS, scaled training programmes, and the ability to combine safety-management roles across fewer people. The obligation still applies, but the implementation is deliberately lighter for smaller operations.
PATL's current operating depth is in Asia, built on the sister-company relationship with L'VOYAGE (founded 2014). PATL is actively expanding toward global markets and toward FBOs and ground handlers in addition to aircraft owners and operators, including engagement with the new EU ground handling oversight regime.
Yes. IS-BAH setup and preparation is a core PATL service, and EASA's own guidance names the IS-BAH standard as recognised supporting evidence for ground handlers declaring compliance under the new EU ground handling regulations. PATL builds SMS and IS-BAH readiness together rather than as separate, disconnected workstreams.
Your data stays confidential and is not shared across clients or third parties. PATL positions independence and confidentiality as foundational to every engagement, which matters specifically in SMS work because safety reporting and incident data are sensitive by nature.
Ray Wilson leads audit and compliance work as an IS-BAO Stage 3 auditor with 15 years of leadership across military, commercial, and business aviation and multi-registry AOC compliance expertise. The broader team combines aviation operating leadership, enterprise technology, and regulatory experience, which is why SMS design at PATL extends into real operational workflows and documentation, not just a compliance checklist.
