Performing maintenance properly – 5 key things to consider
Senior Consultant, Paul White, shares his view on what performing maintenance properly actually means and highlights 5 key areas to consider in order to state that maintenance has been performed properly.
Prior to maintenance being certified, the certifying staff needs to satisfy them self that “all the maintenance ordered has been properly carried out by the organisation “ – Part 145.A.50(a). To get to that stage the work should have been planned i.a.w. Part-145.A.47, with section (a) of this requirement stating that “the organisation shall have a system appropriate to the amount and complexity of work to plan the availability of all necessary personnel, tools, equipment, material, maintenance data and facilities in order to ensure the safe completion of the maintenance work”.
Taking these two key elements of a performing 145 organisation, we can state that to have maintenance performed “properly” we need to consider 5 key things
- tools & equipment
- maintenance data
Briefly then, what does this mean?
- Personnel – Are they competent (Skills, Knowledge, Attitude and behaviour) for the task they are performing? In relation to the technical aspects as well as the consideration of human performance.
- Availability of all necessary tools and equipment. Are they controlled, calibrated, specialist, general?
- Material – Components? Was it the right part for the aircraft/component? Are they in a satisfactory condition, are they appropriately tagged and segregated? Where standard parts may have been used, was that specified in the maintenance data?
- Was the maintenance data current and applicable? Was it readily available for use, when required – Part 145.A.45 (f)
- Were the facilities appropriate, ensuring protection from the weather, and such that contamination was unlikely to occur? This not only goes for the maintenance activity, but for the planning and supervision of the work. Was the environment suitable such that it did not impair the effectiveness of the person performing the task? Part 145.A.25(c)
If we can answer Yes to all of these questions, then the certifying staff can confidently state:
- “all maintenance ordered has been properly carried out by the organisation in accordance with the procedures.”
- … and release the aircraft or component.
