Leading edge tape

[death trap]

This might not be Biplane Specific ( delete if needed ) , but I’d fabric and we might learn something. This is a Factory Built Airplane, not the only one I’ve seen covered this way . Being the Manufacturer covered it does that make it acceptable?
This is the leading edge ....notice the seam and tape
