AS350 Canopy
Hi Everyone,
This is my first post here...I stumbled upon this by accident and couldn't help but post a response.
I have a CAMO that has done a lot of repairs to the canopy structure and this is what we have found and know:
1) the canopy is "Polycarbonate" that is "ultrasonic fused" hence the wire mesh that is between the two layers.
2) the canopy is considered secondary structure.
3) the cracks at the upper door post is due to water ingress that breaks down the bond between the fused poly and wire.
4) the MRR fix is to inject resin up into the crack, allow to cure and then perform the stated repair with resin and glass. If you read it carefully they also tell you to apply vacuum.
the door post joggles and goes under the upper section by approx 4" but the bond is only 1/2" wide throughout the entire structure. To tell you the truth I am very impressed that bond is as strong as it is, and from our experience environmental issues are its biggest concern.
I hope this helps
