Dismantling aircraft armament expendable stores
Overview
This standard identifies the competences you need to dismantle aircraft armament expendable stores (AES), in accordance with approved procedures. It covers both fixed wing and rotary winged aircraft. You will be required to select the appropriate tools and equipment to use, based on the operations to be performed and the equipment to be dismantled. The AES to be dismantled will include items such as aircraft gun ammunition, missiles, torpedoes, bombs and components, rockets, chaff and flare, depth charges and other specific stores. The dismantling activities will include making all necessary checks to ensure that the AES are safely dismantled and left in a safe condition.
Your responsibilities will require you to comply with organisational policy and procedures for the dismantling 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 ensure that all tools, equipment and materials used in the dismantling are correctly accounted for on completion of the activities and that all necessary job/task documentation is completed accurately and legibly. You will be expected to work with a minimum of 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 dismantling techniques and procedures to AES. You will understand the AES equipment being dismantled and its application and will know about the relevant components, fastening and securing 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 dismantling of the AES, for which personnel must be authorised and fully conversant. 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
You must be able to:
- work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines
- establish and, where appropriate, mark component for re-assembly
- ensure that any stored energy or substances are released safely and correctly
- make all isolations and disconnections to the equipment in line with approved procedures
- carry out the dismantling to the agreed level using correct tools and techniques
- store components for re-use in approved locations
- dispose of unwanted components and substances in accordance with approved procedures
- deal promptly and effectively with problems within your control and report those that cannot be solved
- leave the work area and AES assembly in a safe and appropriate condition, free from damage or foreign object debris on completion of the activities
- complete the relevant documentation, in accordance with organisational requirements
Knowledge and Understanding
You need to know and understand:
- the specific safety practices and procedures that you need to observe when working with AES (including any specific legislation, regulations/codes of practice for the activities, equipment or materials)
- the health and safety requirements of the work area where you are carrying out the activities and the responsibility these requirements place on you
- the hazards associated with dismantling AES and with the tools and equipment used and how to minimise them and reduce any risks
- the requirements and importance of understanding and applying human factors as defined by the regulatory requirements and the potential impact if these are not adhered to
the protective equipment that you need to use for both personal protection (PPE) and protection of the AES
the precautions to be taken to prevent electrostatic discharge (ESD) damage to circuits and sensitive components (such as use of earthed wrist straps)
- what constitutes a hazardous voltage and how to recognise victims of electric shock
how to reduce the risks of a phase to earth shock (such as insulated tools, rubber matting and isolating transformers)
how to extract and use information from engineering drawings and related specifications
- how to carry out currency/issue checks on the specifications you are working with
- the components to be dismantled and their function within the particular AES
- the quality control procedures to be followed during dismantling operations
- procedures for ensuring that you have the correct tools, equipment, components and fasteners for the activities
- the techniques used to dismantle the components from the AES without damage
- methods of lifting, handling and supporting the components/equipment during the dismantling activities
- why electrical bonding is critical and why it must be both mechanically and electrically secure
- the procedure for the safe disposal of waste materials
- how to recognise defects (such as leaks, poor seals, misalignment, ineffective fasteners, foreign object damage or contamination)
- the importance of ensuring that the AES is free from dirt, swarf and foreign object damage and of ensuring that any exposed components or pipe ends are correctly covered/protected
- the tools and equipment used in the dismantling activities and their calibration/care and control procedures
- why tool/equipment control is critical and what to do if a tool or piece of equipment is unaccounted for on completion of the activities
- the problems that can occur with the dismantling operations and how these can be overcome
- 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 responsibility and to whom you should report if you have problems that you cannot resolve
Scope/range
Scope Performance
Carry out all of the following during the dismantling of AES:
