Bond Bo 105s
In the mid to late 70s - Bond (or North Scottish as it was then), amassed lots of hours based offshore. THey were stationed on Auk, Forties, Brent and Ninian - to name but a few.
I personally was on Brent when we had 2 almost new Bo 105s (G-BDYZ & G-BEZJ) - over the course of 12 months those 2 aircraft amassed over 1200 Hours each ! During that time they hardly ever left the Brent field - we had a Hangar on Nordraug and did all the maintenance offshore.
They were busy little bees in those days. Some still are, especially the Lighthouse Support Machines.
All Bond Bo 105s were built in the 70s as Bo 105D Models, they were nearly all re-shelled in the 90s to become Bo 105DBS models. The reshelled models are recognisable by their dual serial number on the CAA Registration Database.
Hope that's not too "anoraky".
