URN: SEMAER211
Business Sectors (Suites): Aeronautical Engineering Suite 2
Developed by: Enginuity
Approved on: 30 Mar 2017

Overview

This standard identifies the competences you need to carry out servicing activities on aircrew life preserver equipment, 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 include dismantling the equipment to the appropriate level, and cleaning the various parts using suitable solutions. You will carry out a thorough examination of the life preserver equipment and associated parts, in line with the relevant schedule, identifying and replacing any `lifed' items, damaged, worn or defective parts. You will then reassemble the life preserver equipment, make any required adjustments, and check and test the equipment operation and performance.

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 that 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. 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 provide a sound basis for your work, and will provide an informed approach to applying the appropriate servicing techniques and procedures. You will have a basic understanding of the equipment being serviced, and its application, and will know about the servicing requirements and equipment used, 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.

  4. carry out the servicing activities in the specified sequence and in an agreed timescale
  5. report any instances where the servicing activities cannot be fully met or where there are identified defects outside the planned schedule
  6. complete relevant servicing records accurately and pass them on to the appropriate person
  7. dispose of waste materials in accordance with safe working practices and approved procedures
