Professionalism and Integrity
What is most important is to emphasise the combined responsibility of the organisation, its management and supervisors, its processes and procedures, as well as the individual responsibility of each employee (not just certifying engineers) towards safety.
Everyone has their own idea of what constitutes "professional" behaviour. Human factors training, and a company human factors programme can help set and maintain standards for professional behaviour, and provide staff with the mechanisms and support to enable them to work professionally. The problem might be that although staff know full well what they ought to be doing in keeping with professional standards, they are prevented from behaving as they would wish by organisational problems (e.g. poor procedures, commercial pressures, unavailability of correct tooling, poor training, etc.).
When the subject of professionalism is addressed in a company human factors training course, it is up to the trainer to determine whether any problems which might exist are with the lack of professionalism of individuals, or more systemic issues, and to ‘pitch’ the training accordingly. It should be remembered that professionalism is not something which is only necessary for LAEs or managers; it is important for all personnel whose actions (or non-action) can potentially affect safety and airworthiness, whether directly or indirectly. This also applies to personnel who work outside a Part-145 organisation, including the Operator, airport and ground staff, manufacturers and regulators. It is often said that the aviation industry is as safe as it is in large part due to the professionalism of the people who work within the industry. Appropriate training can re-reinforce the need to maintain such professional standards for all personnel
