Unit AEF10

K1 	Describe the hazards associated with installing aircraft mechanical fasteners,
and with the tools and equipment used (e.g. use of power tools, trailing leads
or hoses, damaged or badly maintained tools and equipment), and how they
can be minimised


K2 	Explain the importance of working to the installation instructions and
appropriate specifications


K3 	Explain the implications if the correct and specified fastener is not fitted to the
component and the impact this could have on the business


K4 	Describe the process for the control of materials, and the need for
component control and quarantine


K5 	Explain the methods of identifying the mechanical fasteners to be used (e.g.
material identification systems, codes used and grain flow indicators)


K6 	Explain why they must obtain design approval before removing and replacing
faulty fasteners


K7 	Describe the purpose and use of joint sealing agents and anti-electrolysis
barriers, and the precautions to be taken when using them


K8 	Explain the regulations concerning electrical bonding and anti-electrolysis
Barriers


K9 	Explain the various types and range of screwed fasteners used on aircraft
fittings, and the methods of installing them


K10 	Explain the types and applications of aircraft rivets, and the advantages of
hollow rivets over solid rivets


K11 	Explain the reasons for using screw fastenings rather than rivets


K12 	Describe the purpose and use of a countersink cage


K13 	Describe the various locking devices used with fastenings


K14 	Describe the purpose and use of locating dowels, gripping pins and gauges,
when carrying out fastening operations


K15 	Describe the procedures to be adopted when removing rivets and other
Fasteners


K16 	Explain the term `quilting', its occurrence and avoidance


K17 	Describe bolt break-offs, and where they occur


K18 	Explain how to check that riveting guns, power tools and attachments are in
a safe and usable condition, and the action to be taken in the event of
identifying defective equipment


K19 	Describe the types of gauges used to measure angles, depths, countersinks
and torque


K20 	Describe how and why tools are calibrated, and how to check that the tools
they are using are within calibration dates


K21 	Explain the importance of conducting the necessary checks to ensure the
accuracy and quality of the installations produced


K22 	Describe the problems that can occur with the installation of the mechanical
fasteners, and how these can be overcome
