Guidelines on how to handle surface damages

Cracks on the wing surface

Cracks and damages on the WingtraOne surface can be of different sizes and in different locations. Usually, small cracks on the wing can be easily covered with duct tape, and flying is still safe. For longer cracks, the location and probability that they spread should be considered.

It is highly recommended to send pictures of any damage to Wingtra Support for a proper assessment of the extent of the damage. Wingtra Support will offer the best solution for each case.

Damaged but safe to fly

1. Scratches or dents on the surface

	Safe to fly No need to cover the damage If needed, put strong tape (i.e. duct tape, such as tesa 4662) over the damage

Damaged but safe to fly with tape

1. Crack near the pitot tube

crack near pitot3

Safe to fly
Put a strong tape (i.e. duct tape, such as tesa 4662) over the crack to mitigate spread
Using an adhesive would not work without cutting out and rebuilding the whole structure

2. Small cracks on the wing

	Safe to fly, even without tape in case of urgency When possible, use a strong tape, such as duct tape, like tesa 4662, or any strong water-resistant tape to cover the crack Flying for a long time without tape can lead to water/moisture getting inside and to issues with the lamination
	For such damage in this area, cover the hole with water-resistant tape and make sure to only hold the plane from the motors

Safe to fly only after fixing

1. Long cracks that can spread

Long cracks like the one in the picture can spread and make the wing unusable
To fix this without laminating, the customer needs to drill a hole through the surface of 2-3mm diameter at the very end of the crack and fix it with strong tape (duct tape)

Step by step instructions

	Starting from the end of the crack as indicated
	Drill a hole measuring 2-3mm in diameter at the end of the crack. We recommend that you use a new drill bit and press gently while drilling Take a picture of the hole and send it to Wingtra Support
	Tape the crack and smooth it as you press it down to avoid air bubbles Take a picture and send it to Wingtra Support

Unsafe to fly - wing replacement

More severe surface damages that do not fall in any of the above categories are not reparable and require replacement of the wing. In this case, you need to reach out either to your distributor or to Wingtra Support (if you have purchased your WingtraOne directly from Wingtra), providing detailed pictures of all the damages.
