IS-BAO Audits

IS-BAO Audits

Normal accidents are not avoided by technology, but by an effective system.

Often, they happen to organizations working in ‘silos’. Unlike the silos farmers use to separate different types of grain, the organizational silos that separate different types of employees are seldom as benign. When employees interact poorly with people outside of their “silo,” it becomes difficult to do the work of the business. Opening a window for organizational accidents.

A tight-knit department that works well together can be a plus for a business. However, organizational silos can be like fortresses within a company and eventually cause serious safety problems that might not be noticed until the damage is done, such an accident or an occurrence.

IS-BAO enables a process for breaking up the silos, developing practices that enables communication and collaboration. Increased communication from management and among employers will increase trust and begin to solve the safety and compliance problems.

Last but not least, when silos are broken, IS-BAO enables the assessment and integration of functional system needs and interdependence, referred to as integrated risk management (IRM). IRM focuses on the overall risk reduction of the organization, thus IS-BAO.

Since 2016, all non E.U.-based business aviation commercial operators must have a Third Country Operator (TCO) authorization from EASA to conduct flights into the E.U. The International Business Aviation Council’s (IBAC) IS-BAO Programme issued in September 2016 an “IS-BAO-INFO-2016-1: EASA TCO SMS” (HERE) to provide guidance, based on the EASA website, and a step-by-step walk-through of the Basic Operator Data (BOD) TCO application pages.

The EASA TCO process assesses the risk profiles of commercial operators using many variables, including an operator’s SMS. To date, EASA has issued nearly 200 TCO authorizations (and counting) to operators implementing the IS-BAO SMS. IS-BAO continues to be an important part of the TCO process.

This IS-BAO INFO is issued to remind operators of the utility of the IS-BAO SMS in the EASA TCO context and to recall that only EASA has the authority to advise on methods for compliance with EASA requirements, such as TCO. Non-European authorities do not have that competence.

EASA confirms that the TCO SMS may be the IS-BAO SMS or a State approved SMS. EASA accepts the operator’s choice

About the IS-BAO Standard

Launched in 2002, the International Standard for Business Aircraft Operations (IS-BAO™) is designed to promote use of high quality operating practices for international business aircraft operations by:

  • Establishing a framework for effective safety and operational processes.
  • Providing tools to perform gap analyses to facilitate the implementation of safety best practices.
  • Delivering a Safety Management System appropriate to your operational profile.

IS-BAO™ is based on International Civil Aviation Organization (ICAO) standards that prepare the operator for both domestic and international operations. It is applicable to both large and small operators, fixed wing and rotor wing, AOC, ATO, Part-SPO, Part-NCC and Part-NCO.

IS-BAO™ was developed by the business aviation community and is maintained by the community via the IS-BAO™ Standards Board, a group of business aviation subject matter experts nominated by IBAC Member Associations. IS-BAO™ builds on the excellent safety record already established in business aviation.

The program centers on the Safety Management System (SMS) and leads the operator from establishing principles, to achieving an effective SMS, and eventually attaining a risk-averse, generative safety culture. Audits are conducted every two years (for Stage Two) and ensure conformance with the standards and recommended practices. The audits also provide valuable feedback to the operator. The registration certificate issued upon successful completion of an audit serves as proof of conformance to key ICAO standards.

Audits concentrate on SMS development through a gradual process of advancing maturity:

  • Stage One confirms that the SMS infrastructure is established and that safety management activities are appropriately targeted.
  • Stage Two ensures that safety risks are being effectively managed.
  • Stage Three verifies that safety management activities are fully integrated into the operator’s business and that a positive safety culture is being sustained.

More than 700 business aviation operators in 35 countries are currently IS-BAO™ registered, and continue to improve their safety risk profile, operating effectiveness and efficiency.
