Training is the structured approach to enhance someone’s knowledge which often involves the undertaking of specific taught courses (theoretical knowledge) or on the job training (skills) where a person is given the knowledge needed to apply theory into practice. Often it is the combination of both. The EGR training without a doubt should be composed of a combination of those elements.
However, competency consists of a number of aspects, of which training is only one. Others include skills, knowledge, experience, appreciation, and understanding of the task at hand. It should be noted that training and/or qualifications alone will not necessarily mean that a person is competent.
Typically, the higher the degree of risk, expertise, and complexity involved in the task, the higher the competency needed.
Engine ground runs inherent risks & ensuring risk avoidance during engine running
Engine runs involved a lot of variables and cannot be considered a standalone procedure. It is intrinsically related to the maintenance organisation and its personnel (technical and not technical), the airport, the local regulations, the weather, etc.
Lots of questions must be answered before starting an engine as when, where, how, who, how long, etc.
On top of all those considerations, it must be noted that maintenance personnel mainly operate engines that are known to have failures, engines that require check after maintenance, engines that require verification, validation, and measurement.
So, to add to the inherent risks of performing an engine run on its own we must add the fact that failure may be present in a latent state.
Considering just the engine run itself, there are two main risks which may arise from engine ground running, these are mainly related to:
○ Loss of Control
○ Incorrect Handling of Engine Malfunctions
Loss of Control
It can be defined as the unintended movement of the aircraft during the run, especially during high power engine running.
Further Information
Engine Ground Running can be offered for many aircraft types – please enquire if you have a group of 4 persons.
