Hello guys. Does anyone have knowledge of who flies for Chevron in Angola.Is it Sonair or Helimalongo or both? Im trying to research which is which.There are some old threads on here from 10 years ago so appreciate some up to date info specifically who carries out the maintenance on the EC225 that fly for Sonair and do they have any expat engineers workng there. An email contact for Director of maintenance would be so helpful....thks
