Blade Repair Standard / V5 23022026
Give constructive feedback on the participants’ above practice
The participants shall:
Practise the ability to:
a. safely remove damaged material from the leading edge of a blade, while creating overlaps and/or scarf joints and the correct surface finish for subsequent repair layers
b. lay up and correctly cure with a vacuum and heat a laminate repair on the leading edge with at least two layers of biax
c. measure the hardness using a Barcol and/or a shore D hardness tester
ELEMENT 30.4 - RELOCATE LEADING EDGE
Learning objectives:
287) The participants can perform the recreation of the leading-edge profile using filler (Skills, intermediate level)
288) The participants can act independently in recreating the leading-edge profile using filler (Ability, intermediate level)
The instructor shall:
Demonstrate the tools and techniques that can be used to shape the filler to the approximate profile shape of the leading edge, and explain that the final profile shape will be obtained by sanding
Facilitate practice to improve the participants’ ability to:
a. apply filler to a laminate repair on the leading edge, and to shape the filler to approximately match the surrounding aerodynamic profile of the leading edge
b. shape the cured filler with a sander so that it accurately matches the surrounding aerodynamic profile of the leading edge and has the correct surface finish for the adhesion of paint
c. apply the knowledge gained in Lesson 21 (Painting) by applying two-factor component paint to repairs using a roller
