Carrying out routine servicing of aircraft
Overview
This standard identifies the competences you need to carry out routine servicing of commercial, military, light aircraft and rotary wing aircraft, in accordance with approved procedures. You will be required to select the appropriate tools and equipment to use, based on the servicing activities to be carried out and to check that they are in a safe and serviceable condition. You will be required to manoeuvre the aircraft to the appropriate location and prepare the aircraft for work. The servicing activities will involve defueling and refuelling (as appropriate), replenishing oxygen systems, replenishing oil systems, checking undercarriages and wheels and completing servicing records.
Your responsibilities will require you to comply with organisational policy and procedures for the servicing activities undertaken and to report any problems that you cannot personally resolve, or that are outside your permitted authority, to the relevant people. You will be expected to work with minimal supervision, taking personal responsibility for your own actions and for the quality and accuracy of the work that you carry out.
Your underpinning knowledge will provide a good understanding of your work and will provide an informed approach to applying the appropriate servicing techniques and procedures. You will understand the systems being serviced and their application and will know about the replenishment equipment and fastening devices, in adequate depth to provide a sound basis for carrying out the activities to the required specification.
You will understand the safety precautions required when carrying out the servicing operations. You will be required to demonstrate safe working practices throughout and will understand the responsibility you owe to yourself and others in the workplace.
Performance criteria

- carry out the maintenance activities in the specified sequence and in an agreed timescale
- report any instances where the servicing or maintenance activities cannot be fully met or where there are identified defects outside the planned schedule
complete the relevant maintenance records, in accordance with organisational requirements
dispose of waste materials in accordance with safe working practices and approved procedures
- leave the work area and aircraft in a safe and appropriate condition, free from foreign object debris on completion of the activities

- the tools and equipment used in the servicing activities and their calibration/care and control procedures.
- the importance of ensuring that, when the servicing is completed, the aircraft is free from dirt, swarf and foreign objects
- the disposal methods for waste oil, fuel and other liquids and waste
- problems with the servicing procedures and the importance of informing appropriate people of defects
- the recording documentation to be completed for the activities undertaken and where appropriate, the importance of marking and identifying specific pieces of work in relation to the documentation
- the extent of your own responsibility and to whom you should report if you have problems that you cannot resolve
