Aviation Part 145 SMS Practical Safety Auditing & Setting Performance Indicators – 2 Days


An EASA Part 145 Aircraft Maintenance Organisation (AMO) or Maintenance Repair Organisation (MRO) is an incredibly complex business environment.

Demands placed on the organization and individuals to deliver are often considerable and place a burden on key individuals.

On a daily basis, we make decisions in real-time, weighing the probability and severity of any adverse consequences implied by the risk against the expected gain of taking the risk. (This process is known as risk management.” – ICAO).

We accept that absolute safety is generally an unachievable and very expensive goal, therefore the concept of acceptable safety has been adopted in aviation. The term “acceptable risk” describes an event with a probability of occurrence and consequences acceptable to society.

Managing Risks in Aviation

“The risks and costs in commercial aviation necessitate a rational process for decision-making.”

The term Acceptable Level of Safety (ALoS) defines an aviation service provider’s minimum level of acceptable risk for a given safety issue. “Acceptable” describes the need for no further mitigatory actions on the part of the service provider for the safety concern in question.

Safety performance indicators (SPI’s) should meet quality criteria to assure they are quantifiable, representative to safety performance, comprehendible, and can be cost-efficiently used. Developed safety performance indicators should be related to the main operational safety issues.

“You cannot manage what you cannot measure”

The concept of an acceptable level of safety is expressed by two specific metrics, namely safety performance targets and safety performance indicators.

This recurrent course details the process by which we can perform an effective audit of our Safety Management System and to develop meaningful Safety Performance Indicators.
