This standard identifies the competences you need to prepare aircraft component coating/finishing materials for application by brush, roller or spray, in accordance with approved procedures. You will be required to obtain all information necessary to carry out the preparations of the coating/finishing materials. You will be expected to select the appropriate preparation or mixing equipment, and to ensure that it is fit for purpose. You will be expected to prepare a variety of coatings for a range of applications, which will include the painting and/or protection of bare substrates and the overcoating of previously painted surfaces. You will be required to check that all coatings have been prepared in accordance with manufacturers' recommendations for the application conditions.

Your responsibilities will require you to comply with organisational policy and procedures for the preparation of the coating materials, and for the disposal of surplus product, arisings, and contaminated solvents. You will be required to report any problems with the preparation activities, equipment or materials that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You will need to ensure that all tools, equipment and materials used in the preparation are correctly accounted for on completion of the activities, and you must complete all necessary job/task documentation accurately and legibly.

You will be expected to work either with a high level of supervision or as a member of a team, and you will take personal responsibility for your own actions and for the quality and accuracy of the work that you carry out. Where team working is involved, you must demonstrate a significant personal contribution during the team activities in order to satisfy the requirements of this standard, and you must demonstrate competence in all the areas required by the standard.

Your underpinning knowledge will be sufficient to provide a sound basis for your work, and will provide an informed approach to the preparation of aircraft coating/finishing materials. You will have an understanding of the properties of the aircraft coatings and the applications for which they are intended. You will know about pot life, induction times, viscosity and temperature conditioning requirements, in sufficient depth to provide a sound basis for carrying out the activities, and for ensuring that the coatings are prepared to the required standards.

You will understand the safety precautions required when carrying out the preparation activities, and when using the associated tools and equipment. You will be required to demonstrate safe working practices throughout. You will also understand your responsibilities for safety, and the importance of taking the necessary safeguards to protect yourself and others in the workplace.
