I was surprised ( & a little sceptical) to see a comment like that from Ergon. I've been working with them & talking to them about marking wires for 15 years & was always told by them that it is always pilot error & they won't be moving/marking wires. Maybe the winds of "Duty of care" are blowing softly through Ergon?
I'd like to give them the benefit of the doubt, but given the size of the SWER line network in this country & the cost involved in modifying it to make it safer for airwork aircraft I don't believe for a minute that anything more than a glossy brochure for pilots will come from their "develop strategies" initiatives.
Good to hear Chris is mending, I hope the observer is doing well also.
