Ahh, had you filled in a Risk Assesment? :diablo:

Where high wings are to be found, I am told that the BBMF have some fancy suction system that sits on top of the wing and then the personnel can attach themselves to it with a lanyard.

I remember many years ago at Dx someone was working on Lindsays Corsair, started to slide off & grabbed the brace which resulted in him dislocating his shoulder.
Altho given the mists of time it may have been the OFMC Corsair, I know it wasn’t TFC’s one.
