Carrying out aircraft routine servicing
Overview
This standard identifies the competences you need to carry out routine servicing of commercial, military or light aircraft, both fixed wing and rotary, 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. The servicing activities will involve assisting in de-fuelling, refuelling and replenishing gaseous systems, replenishing oil systems, checking undercarriages and wheels/skids, 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 with these activities that you cannot personally resolve, or are outside your permitted authority, to the relevant people. 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. You must demonstrate a significant personal contribution during the team activities, in order to satisfy the requirements of this standard, and competency in all the areas required by the standard must be demonstrated.
Your underpinning knowledge will be sufficient to provide a good understanding of your work and will provide an informed approach to applying the appropriate aircraft 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 aircraft 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.

P4 carry out the servicing activities in the specified sequence and in an agreed timescale
P5 report any instances where the servicing activities cannot be fully met or where there are identified defects outside the planned schedule
P6 complete and store all relevant documentation in accordance with organisational requirements
P7 dispose of waste materials in line with organisational and environmentally safe procedures

K7 the replenishments to be made, and the methods of replenishment
K8 electrical bonding/earthing specifications, and their importance
K9 how to identify the fuels, lubricants and gases to be used, and how to ensure that systems are not contaminated
K10 the procedures for checking undercarriages and wheels
K11 the quality control procedures to be followed during the servicing procedures
K12 how to conduct any necessary checks to ensure the system integrity and functionality
K13 the issues that can occur with the servicing and maintenance activities, and how these can be overcome
K14 the importance of correct securing and locking of connections
K15 the importance of tool control, and company tool control procedures
K16 how replenishment equipment is cared for, connected, operated and controlled
K17 the methods and equipment used to replenish aircraft systems, and how to check that the equipment is within its current certification dates
K18 the tools and equipment used in the servicing activities, and their calibration/care and control procedures.
K19 the importance of ensuring that, when the servicing is completed, the aircraft is free from dirt, swarf and foreign objects (FOD)
K20 the disposal methods for waste oil, fuel, other liquids and waste
K21 issues with the servicing procedures, and the importance of informing appropriate people of defects
K22 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
K23 the extent of your own responsibility, and to whom you should report if you have problems that you cannot resolve
