Blade Repair Standard / V4 2023-05-02
Explain the requirement to perform repairs in accordance with an approved work instruction by considering the safety and quality implications of repair work on the trailing edge Using the trailing edge section created in the sandwich panel topic create a crack running parallel to the trailing edge that extends through both sides of the trailing edge section but allows sufficient undamaged material at either end of the crack to allow the correct overlaps for the laminate repair
Demonstrate:
a. how to remove the damaged material from the trailing edge
b. how to create a temporary hardback repair on one side of the trailing edge and explain that this is temporary and to support the lamination of the other side of the trailing edge c. how to laminate and cure one side of the trailing edge using the temporary hardback repair as a support for the lamination d. how to remove the temporary hardback repair, and laminate and cure the remaining side of the trailing edge Facilitate practice to improve the participants’ ability to repair cracks running parallel to the trailing edge by using a temporary hardback repair to support the laminate repair on one side of the trailing edge, and then removing the temporary hardback and completing the repair by laminating the remaining side of the trailing edge
Give constructive feedback on the participants’ ability to repair cracks running parallel to the trailing edge
The participants shall:
Practise the ability to repair cracks running parallel to the trailing edge by using a temporary hardback repair to support the laminate repair on one side of the trailing edge and then removing the temporary hardback and completing the repair by laminating the remaining side of the trailing edge
